This table contains the full text for all our old WORDPRESS content in html form. The format is a bit odd as it represents a direct copy from wordpress content that includes a lot of wordpress specific comments that carry some meaning in terms of layout instructions etc.. The html in the content column can thus be rendered as is but will not look identical to the way it looks on our website as several post processing steps are not applied yet. The content should work though as a readable approximation for every post. For easy searching etc, a markdown copy of the content is available in the markdown column. If you want to query all posts (both wordpress and gdocs), use the posts_unified table or the posts_unified_with_content view.

1567	Happiness and Life Satisfaction	happiness-and-life-satisfaction	page	publish	<!-- wp:html --> <div class="blog-info"> <p>First published in 2013; substantive revision May 2017.</p> <p>The <strong>French translation</strong> of this entry is here: <a href="https://ourworldindata.org/bonheur-et-satisfaction/">Bonheur et satisfaction</a></p> </div> <!-- /wp:html --> <!-- wp:paragraph --> <p>How happy are people today? Were people happier in the past? How satisfied with their lives are people in different societies? And how do our living conditions affect all of this?</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>These are difficult questions to answer; but they are questions that undoubtedly matter for each of us personally. Indeed, today, life satisfaction and happiness are central research areas in the social sciences, including in ‘mainstream’ economics.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Social scientists often recommend that measures of subjective well-being should augment the usual measures of economic prosperity, such as <a rel="noopener noreferrer" href="https://ourworldindata.org/economic-growth" target="_blank">GDP per capita</a>.{ref}Particularly important was the <a rel="noreferrer noopener" href="https://en.wikipedia.org/wiki/Commission_on_the_Measurement_of_Economic_Performance_and_Social_Progress" target="_blank">Stiglitz-Sen-Fitoussi Commission</a>. It also relates to Bhutan’s famous measurement of Gross National Happiness (GNH) as indicator of progress (Wikipedia <a rel="noreferrer noopener" href="http://en.wikipedia.org/wiki/Gross_national_happiness" target="_blank">here</a>).{/ref} But how can happiness be measured? Are there reliable comparisons of happiness across time and space that can give us clues regarding what makes people declare themselves ‘happy’?</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>In this entry, we discuss the data and empirical evidence that might answer these questions. Our focus here will be on survey-based measures of self-reported happiness and life satisfaction. Here is a preview of what the data reveals.</p> <!-- /wp:paragraph --> <!-- wp:list {"ordered":true} --> <ol><li>Surveys asking people about life satisfaction and happiness do measure subjective well-being with reasonable accuracy.</li><li>Life satisfaction and happiness vary widely both within and among countries. It only takes a glimpse at the data to see that people are distributed along a wide spectrum of happiness levels.</li><li>Richer people tend to say they are happier than poorer people; richer countries tend to have higher average happiness levels; and across time, most countries that have experienced sustained economic growth have seen increasing happiness levels. So the evidence suggests that income and life satisfaction tend to go together (which still doesn’t mean they are one and the same).</li><li>Important life events such as marriage or divorce do affect our happiness, but have surprisingly little long-term impact. The evidence suggests that people tend to adapt to changes.</li></ol> <!-- /wp:list --> <!-- wp:heading --> <h2>Happiness across the world today</h2> <!-- /wp:heading --> <!-- wp:paragraph --> <p>The World Happiness Report is a well-known source of cross-country data and research on self-reported life satisfaction. The map here shows, country by country, the ‘happiness scores’ published this report.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The underlying source of the happiness scores in the World Happiness Report is the <a href="http://www.gallup.com/services/170945/world-poll.aspx" target="_blank" rel="noopener noreferrer">Gallup World Poll</a>—a set of nationally representative surveys undertaken in more than 160 countries in over 140 languages. The main life evaluation question asked in the poll is: “Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?” (Also known as the “Cantril Ladder”.)</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The map plots the average answer that survey-respondents provided to this question in different countries. As with the steps of the ladder, values in the map range from 0 to 10.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>There are large differences across countries. According to the most recent figures, European countries top the ranking: Finland, Denmark, Iceland, Switzerland and the Netherlands have the highest scores (all with averages above 7). In the same year, the lowest national scores correspond to Afghanistan, Lebanon, Zimbabwe, Rwanda and Botswana (all with average scores below 3.5).</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>You can click on any country on the map to plot time-series for specific countries.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>As we can see, self-reported life satisfaction correlates with other measures of well-being—richer and healthier countries tend to have higher average happiness scores. (More on this in the section <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#correlates-determinants-and-consequences">below</a>.)</p> <!-- /wp:paragraph --> <!-- wp:html --> <iframe src="https://ourworldindata.org/grapher/happiness-cantril-ladder" width="“300”" height="“150”"></iframe> <!-- /wp:html --> <!-- wp:heading --> <h2>Happiness over time</h2> <!-- /wp:heading --> <!-- wp:heading {"level":4} --> <h4>Findings from the World Value Survey</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>In addition to the Gallup World Poll (discussed above), the <a href="http://www.worldvaluessurvey.org/WVSDocumentationWV6.jsp">World Value Survey</a> also provides cross-country data on self-reported life satisfaction. These are the longest available time series of cross-country happiness estimates that include non-European nations.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The World Value Survey collects data from a series of representative national surveys covering almost 100 countries, with the earliest estimates dating back to 1981. In these surveys, respondents are asked: “Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy or (iv) Not at all happy”. This visualization plots the share of people answering they are Very happy or Rather happy.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>As we can see, in the majority of countries the trend is positive: In 49 of the 69 countries with data from two or more surveys, <a href="https://ourworldindata.org/grapher/share-who-say-happy-wvs-first-to-last">the most recent observation is higher than the earliest</a>. In some cases, the improvement has been very large; in Zimbabwe, for example, the share of people who reported being ‘very happy’ or ‘rather happy’ went from 56.4% in 2004 to 82.1% in 2014.</p> <!-- /wp:paragraph --> <!-- wp:html --> <iframe src="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy" width="“300”" height="“150”"></iframe> <!-- /wp:html --> <!-- wp:heading {"level":4} --> <h4>Findings from Eurobarometer</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>The <a href="http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/General/index">Eurobarometer</a> collects data on life satisfaction as part of their public opinion surveys. For several countries, these surveys have been conducted at least annually for more than 40 years. The visualization here shows the share of people who report being ‘very satisfied’ or ‘fairly satisfied’ with their standards of living, according to this source.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Two points are worth emphasizing. First, estimates of life satisfaction often fluctuate around trends. In France, for example, we can see that the overall trend in the period 1974-2016 is positive; yet there is a pattern of ups and downs. And second, despite temporary fluctuations, decade-long trends have been generally positive for most European countries.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>In most cases, the share of people who say they are ‘very satisfied’ or ‘fairly satisfied’ with their life has gone up over the full survey period.{ref}To be precise, in 27 out of 31 countries with data spanning longer than one decade, the estimate for 2016 is higher than the earliest available estimate.{/ref} Yet there are some clear exceptions, of which Greece is the most notable example. Add Greece to the chart and you can see that in 2007, around 67% of the Greeks said they were satisfied with their life; but five years later, after the financial crisis struck, the corresponding figure was down to 32.4%. Despite recent improvements, Greeks today are on average much less satisfied with their lives than before the financial crisis. No other European country in this dataset has gone through a comparable negative shock.</p> <!-- /wp:paragraph --> <!-- wp:html --> <iframe src="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy-eurobarometer" width="“300”" height="“150”"></iframe> <!-- /wp:html --> <!-- wp:heading --> <h2>The distribution of life satisfaction</h2> <!-- /wp:heading --> <!-- wp:heading {"level":4} --> <h4>More than averages—the distribution of life satisfaction scores</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>Most of the studies comparing happiness and life satisfaction among countries focus on averages. However, distributional differences are also important.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Life satisfaction is often reported on a scale from 0 to 10, with 10 representing the highest possible level of satisfaction. This is the so-called ‘Cantril Ladder’. This visualization shows how responses are distributed across steps in this ladder. In each case, the height of bars is proportional to the fraction of answers at each score. Each differently-colored distribution refers to a world region; and for each region, we have overlaid the distribution for the entire world as a reference.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>These plots show that in sub-Saharan Africa—the region with the lowest average scores–the distributions are consistently to the left of those in Europe. In economics lingo, we observe that the distribution of scores in European countries <em>stochastically dominates</em> the distribution in sub-Saharan Africa.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>This means that the share of people who are ‘happy’ is lower in sub-Saharan Africa than in Western Europe, independently of which score in the ladder we use as a threshold to define ‘happy’. Similar comparisons can be made by contrasting other regions with high average scores (e.g. North America, Australia and New Zealand) against those with low average scores (e.g. South Asia).</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Another important point to notice is that the distribution of self-reported life satisfaction in Latin America is high across the board—it is consistently to the right of other regions with roughly comparable income levels, such as Central and Eastern Europe.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>This is part of a broader pattern: Latin American countries tend to have a higher subjective well-being than other countries with comparable levels of economic development. As we will see in the section on <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#the-relationship-between-culture-and-life-satisfaction">social environment</a>, culture and history matter for self-reported life satisfaction.</p> <!-- /wp:paragraph --> <!-- wp:image --> <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2017/04/The-distribution-of-life-satisfaction.png" alt="Distribution of self-reported life satisfaction by world region"/></figure> <!-- /wp:image --> <!-- wp:paragraph --> <p>If you are interested in data on country-level distributions of scores, the <a href="http://www.pewglobal.org/question-search/?qid=365&cntIDs=&stdIDs=">Pew Global Attitudes Survey</a> provides such figures for more than 40 countries.</p> <!-- /wp:paragraph --> <!-- wp:heading --> <h2>(Mis)perceptions about others' happiness</h2> <!-- /wp:heading --> <!-- wp-block-tombstone 26982 --> <!-- wp:paragraph --> <p>We tend to underestimate the average happiness of people around us. The visualization shown demonstrates this for countries around the world, using data from Ipsos' <a rel="noopener noreferrer" href="http://perils.ipsos.com/" target="_blank">Perils of Perception</a>—a cross-country survey asking people to guess what others in their country have answered to the happiness question in the World Value Survey.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The horizontal axis in this chart shows the actual share of people who said they are 'Very Happy' or 'Rather Happy' in the World Value Survey; the vertical axis shows the average <em>guess</em> of the same number (i.e. the average guess that respondents made of the share of people reporting to be 'Very Happy' or 'Rather Happy' in their country).</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>If respondents would have guessed the correct share, all observations would fall on the red 45-degree line. But as we can see, all countries are far below the 45-degree line. In other words, people in every country underestimated the self-reported happiness of others. The most extreme deviations are in Asia—South Koreans think that 24% of people report being happy, when in reality 90% do.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The highest guesses in this sample (Canada and Norway) are 60%—this is lower than the lowest actual value of self-reported happiness in any country in the sample (corresponding to Hungary at 69%).</p> <!-- /wp:paragraph --> <!-- wp:image {"id":11310,"align":"center","linkDestination":"custom"} --> <div class="wp-block-image"><figure class="aligncenter"><a href="https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others.png"><img src="https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others-550x550.png" alt="" class="wp-image-11310"/></a></figure></div> <!-- /wp:image --> <!-- wp:paragraph --> <p>Why do people get their guesses so wrong? It's not as simple as brushing aside these numbers by saying they reflect differences in 'actual' vs. reported happiness.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>One possible explanation is that people tend to misreport their own happiness, therefore the average guesses might be a correct indicator of true life satisfaction (and an incorrect indicator of <em>reported</em> life satisfaction). However, for this to be true, people would have to commonly misreport their own happiness while assuming that others do <em>not</em> misreport theirs.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>And people are not bad at judging the well-being of other people who they know: There is substantial evidence showing that <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#can-happiness-really-be-measured">ratings of one's happiness made by friends correlate with one's happiness</a>, and that <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#how-much-does-language-matter-for-cross-country-comparisons-of-happiness">people are generally good at evaluating emotions from simply watching facial expressions</a>.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>An alternative explanation is that this mismatch is grounded in the well-established fact that people tend to be positive about themselves, but negative about other people they don't know.It has been observed in other contexts that people can be optimistic about their own future, while at the same time being deeply pessimistic about the future of their nation or the world. We discuss this phenomenon in more detail in our entry on <a href="https://ourworldindata.org/optimism-pessimism/">optimism and pessimism</a>, specifically in a section dedicated to <a href="https://ourworldindata.org/optimism-pessimism/#individual-optimism-and-social-pessimism">individual optimism and social pessimism</a>.</p> <!-- /wp:paragraph --> <!-- wp:heading --> <h2>Differences in happiness within countries</h2> <!-- /wp:heading --> <!-- wp:heading {"level":3} --> <h3>East and West Germany</h3> <!-- /wp:heading --> <!-- wp-block-tombstone 26506 --> <!-- wp:paragraph --> <p>In global surveys of happiness and life satisfaction, <a rel="noopener noreferrer" href="https://ourworldindata.org/grapher/happiness-cantril-ladder" target="_blank">Germany usually ranks high</a>.

This can still be consistent with growing income inequality, since public goods such as <a href="https://ourworldindata.org/health-meta/">better health</a> affect incomes and well-being differently.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Another possibility is that economic growth in rich countries has translated into a more diverse society in terms of cultural expressions (e.g. through the emergence of alternative lifestyles), which has allowed people to converge in happiness even if they diverge in incomes, tastes and consumption. Steven Quartz and Annette Asp explain this hypothesis in a <a href="https://www.nytimes.com/2015/04/12/opinion/sunday/unequal-yet-happy.html?smid=nytcore-ipad-share&smprod=nytcore-ipad&_r=0" target="_blank" rel="noopener noreferrer">New York Times article</a>, discussing evidence from experimental psychology.</p> <!-- /wp:paragraph --> <!-- wp:heading --> <h2>The link between happiness and income</h2> <!-- /wp:heading --> <!-- wp:heading {"level":3} --> <h3>The link across countries</h3> <!-- /wp:heading --> <!-- wp:heading {"level":4} --> <h4>Higher national incomes go together with higher average life satisfaction</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>If we compare life satisfaction reports from around the world at any given point in time, we immediately see that countries with higher average national incomes tend to have higher average life satisfaction scores.

In other words, the cross-country relationship between income and happiness is not linear on income (it is ‘log-linear’).

Some countries in some periods experience economic growth without increasing happiness. The experience of the US in recent decades is a case in point. These instances may seem paradoxical given the evidence—we explore this question in the following section.</p> <!-- /wp:paragraph --> <!-- wp:image {"id":43177,"sizeSlug":"full","linkDestination":"none"} --> <figure class="wp-block-image size-full"><img src="https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time.png" alt="" class="wp-image-43177"/></figure> <!-- /wp:image --> <!-- wp:heading {"level":3} --> <h3>The Easterlin Paradox</h3> <!-- /wp:heading --> <!-- wp:paragraph --> <p>The observation that economic growth does not always go together with increasing life satisfaction was first made by Richard Easterlin in the 1970s. Since then, there has been much discussion over what came to be known as the ‘Easterlin Paradox’.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>At the heart of the paradox was the fact that richer countries tend to have higher self-reported happiness, yet in some countries for which repeated surveys were available over the course of the 1970s, happiness was not increasing with rising national incomes. This combination of empirical findings was paradoxical because the cross-country evidence (countries with higher incomes tended to have higher self-reported happiness) did not, in some cases, fit the evidence over time (countries seemed not to get happier as national incomes increased).</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Notably, Easterlin and other researchers relied on data from the US and Japan to support this seemingly perplexing observation. If we look closely at the data underpinning the trends in these two countries, however, these cases are not in fact paradoxical.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Let us begin with the case of Japan. There, the earliest available data on self-reported life satisfaction came from the so-called ‘Life in Nation surveys’, which date back to 1958. At first glance, this source suggests that mean life satisfaction remained flat over a period of spectacular economic growth (see for example <a href="http://ourworldindata.org/app/uploads/2013/05/mean-subjective-well-being-japan-1958-1987-easterlin-in-land-michalos-and-sirgy-ed-2011.png">this chart</a> from Easterlin and Angelescu 2011).{ref}R.A.

The visualization here splits the life satisfaction data from the surveys into sub-periods where the questions remained constant. As we can see, the data is not supportive of a paradox: the correlation between GDP and happiness growth in Japan is positive within comparable survey periods. The reason for the alleged paradox is in fact mismeasurement of how happiness changed over time.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>In the US, the explanation is different, but can once again be traced to the underlying data. Specifically, if we look more closely at economic growth in the US over the recent decades, one fact looms large: growth has not benefitted the majority of people. Income inequality in the US is exceptionally high and has been on the rise in the last four decades, with incomes for the median household growing much more slowly than incomes for the top 10%. As a result, trends in aggregate life satisfaction should not be seen as paradoxical: the income and standard of living of the typical US citizen has not grown much in the last couple of decades.

However, it is important to bear in mind that “life satisfaction” and “happiness” are not really synonyms. And this is of course reflected in the data, since self-reported measures of these two variables come from asking different kinds of questions.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The World Value Survey asks directly about happiness: <em>“Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy, (iv) Not at all happy, (v) Don’t know.”</em></p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The Gallup World Poll, on the other hand, uses the Cantril Ladder question and asks respondents to evaluate their life: <em>“Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?”</em></p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>As the following scatter plot shows, these two measures are clearly closely related (countries that score high in one measure also tend to score high in the other), yet they are not identical (there is substantial dispersion, with many countries sharing the same score in one variable but diverging in the other).</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The differences in responses to questions inquiring about life satisfaction and happiness are consistent with the idea that subjective well-being has two sides: an experiential or emotional side, and an evaluative or cognitive side. Of course, the limits between emotional and cognitive aspects of well-being are blurred in our minds; so in practice both kinds of questions measure both aspects to some degree. Indeed, social scientists often construct ‘subjective well-being indexes’ where they simply average out results from various types of questions.</p> <!-- /wp:paragraph --> <!-- wp:html --> <iframe src="https://ourworldindata.org/grapher/Happiness-WVS-vs-Gallup" width="“300”" height="“150”"></iframe> <!-- /wp:html --> <!-- wp:heading {"level":3} --> <h3>Are happiness averages really meaningful?</h3> <!-- /wp:heading --> <!-- wp:paragraph --> <p>The most common way to analyze data on happiness consists in taking averages across groups of people. Indeed, cross-country comparisons of self-reported life satisfaction, such as those presented in ‘happiness rankings’, rely on national averages of reports on a scale from 0 to 10 (the Cantril Ladder).</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Is it reasonable to take averages of life satisfaction scores? Or, in more technical terms: are self reports of Cantril scores really a cardinal measure of well-being?</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The evidence tells us that survey-based reports on the Cantril Ladder do allow cardinal measurement reasonably well—respondents have been found to translate verbal labels, such as ‘very good’ and ‘very bad’, into roughly the same numerical values.{ref}Ferrer‐i‐Carbonell, A., & Frijters, P. (2004). How important is methodology for the estimates of the determinants of happiness?. The Economic Journal, 114(497), 641-659.{/ref} {ref}Van Praag, B.M.S. (1991). ‘Ordinal and cardinal utility: an integration of the two dimensions of the welfare concept’, Journal of Econometrics, vol. 50, pp. 69–89.{/ref}</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>But as with any other aggregate indicator of social progress, averages need to be interpreted carefully, even if they make sense arithmetically. For example, if we look at happiness by age in a given country, we may see that older people do not appear to be happier than younger people. Yet this may be because the average-by-age figure from the snapshot confounds two factors: the age effect (people from the same cohort do get happier as they grow older, across all cohorts) and the cohort effect (across all ages, earlier generations are less happy than more recent generations). If the cohort effect is very strong, the snapshot can even give a picture that suggests people become <em>less</em> happy as they grow older, even though the exact opposite is actually true within all generations.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>This example is in fact taken from the real world: using data from the US, Sutin et al. (2013){ref}Sutin, A. R., Terracciano, A., Milaneschi, Y., An, Y., Ferrucci, L., & Zonderman, A. B. (2013). The effect of birth cohort on well-being The legacy of economic hard times. Psychological science, 0956797612459658.{/ref} showed that self-reported feelings of well-being tend to increase with age across generations, but overall levels of well-being depend on when people were born.</p> <!-- /wp:paragraph --> <!-- wp:heading {"level":4} --> <h4>How much does language matter for cross-country comparisons of happiness?</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>Linguistic differences are often seen as a major obstacle for making cross-country comparisons of happiness. However, there is evidence suggesting that comparability issues, at least in respect to language, are less problematic than many people think.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Studies have shown, for example, that in interviews in which respondents are shown pictures or videos of other individuals, respondents can broadly identify whether the individual shown to them was happy or sad; and this is also true when respondents were asked to predict the evaluations of individuals from other cultural communities. (For evidence of this see Sandvik et al., 1993; Diener and Lucas, 1999).{ref}Sandvik, E., Diener, E. and Seidlitz, L. (1993). ‘Subjective well-being: the convergence and stability of self and non self report measures’, Journal of Personality, vol. 61, pp. 317–42. Diener, E. and Lucas, R.E. (1999). ‘Personality and subjective well-being’, in Kahneman et al. (1999) chapter 11.{/ref}</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Studies have also shown that ‘indigenous emotions’ across cultures (i.e. feelings that are unique in that they do not have equivalents in the English language) are not experienced any more frequently or differently than common translated emotions. (See Scollon et al. 2005).{ref}Scollon, C. N., Diener, E., Oishi, S., & Biswas-Diener, R. (2004). Emotions across cultures and methods. Journal of cross-cultural psychology, 35(3), 304-326.{/ref}</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The conclusion, therefore, seems to be that there is some basic understanding among humans about what it means to be ‘happy’. Survey-based measures of self-reported life satisfaction are informative about cross-country differences, even if these comparisons are obviously noisy.</p> <!-- /wp:paragraph --> <!-- wp:heading --> <h2>Data Sources</h2> <!-- /wp:heading --> <!-- wp:heading {"level":4} --> <h4>Cross-country estimates</h4> <!-- /wp:heading --> <!-- wp:heading {"level":4} --> <h4><a id="World_Happiness_Report_379"></a>World Happiness Report</h4> <!-- /wp:heading --> <!-- wp:list --> <ul><li><strong>Data:</strong> Country averages of self-reported life satisfaction (Question: Cantril Ladder).</li><li><strong>Underlying source:</strong> Gallup World Poll</li><li><strong>Time span:</strong> 2005-2022</li><li><strong>Available at:</strong> <a href="http://worldhappiness.report/">World Happiness Report</a></li></ul> <!-- /wp:list --> <!-- wp:heading {"level":4} --> <h4><a id="European_Commission__Eurobarometer_Interactive_386"></a>European Commission – Eurobarometer Interactive</h4> <!-- /wp:heading --> <!-- wp:list --> <ul><li><strong>Data:</strong> Life satisfaction (Question: <em>“On the whole are you very satisfied, fairly satisfied, not very satisfied or not at all satisfied with the life you lead ?”</em>)</li><li><strong>Geographical coverage:</strong> EU countries</li><li><strong>Time span:</strong> 1973 - 2015</li><li><strong>Available at:</strong> <a href="http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index">http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index</a></li></ul> <!-- /wp:list --> <!-- wp:separator --> <hr class="wp-block-separator"/> <!-- /wp:separator --> <!-- wp:heading {"level":4} --> <h4><a id="The_World_Value_Survey_WVS_395"></a>The World Value Survey (WVS)</h4> <!-- /wp:heading --> <!-- wp:list --> <ul><li><strong>Data:</strong> Happiness and life satisfaction, as well as many other social and cultural characteristics from cross-national time-series surveys.

between people and between countries. What explains these differences?	2017-12-04 10:21:32	2023-10-11 12:46:15	https://ourworldindata.org/wp-content/uploads/2021/03/Screen-Shot-2021-03-25-at-17.09.58.png	{}	First published in 2013; substantive revision May 2017. The French translation of this entry is here: [Bonheur et satisfaction](https://ourworldindata.org/bonheur-et-satisfaction/) How happy are people today? Were people happier in the past? How satisfied with their lives are people in different societies? And how do our living conditions affect all of this? These are difficult questions to answer; but they are questions that undoubtedly matter for each of us personally. Indeed, today, life satisfaction and happiness are central research areas in the social sciences, including in ‘mainstream’ economics. Social scientists often recommend that measures of subjective well-being should augment the usual measures of economic prosperity, such as [GDP per capita](https://ourworldindata.org/economic-growth).{ref}Particularly important was the [Stiglitz-Sen-Fitoussi Commission](https://en.wikipedia.org/wiki/Commission_on_the_Measurement_of_Economic_Performance_and_Social_Progress). It also relates to Bhutan’s famous measurement of Gross National Happiness (GNH) as indicator of progress (Wikipedia [here](http://en.wikipedia.org/wiki/Gross_national_happiness)).{/ref} But how can happiness be measured? Are there reliable comparisons of happiness across time and space that can give us clues regarding what makes people declare themselves ‘happy’? In this entry, we discuss the data and empirical evidence that might answer these questions. Our focus here will be on survey-based measures of self-reported happiness and life satisfaction. Here is a preview of what the data reveals. 0. Surveys asking people about life satisfaction and happiness do measure subjective well-being with reasonable accuracy. 1. Life satisfaction and happiness vary widely both within and among countries. It only takes a glimpse at the data to see that people are distributed along a wide spectrum of happiness levels. 2. Richer people tend to say they are happier than poorer people; richer countries tend to have higher average happiness levels; and across time, most countries that have experienced sustained economic growth have seen increasing happiness levels. So the evidence suggests that income and life satisfaction tend to go together (which still doesn’t mean they are one and the same). 3. Important life events such as marriage or divorce do affect our happiness, but have surprisingly little long-term impact. The evidence suggests that people tend to adapt to changes. [See all interactive charts on happiness and life satisfaction ↓](#all-charts) --- # Happiness across the world today --- The World Happiness Report is a well-known source of cross-country data and research on self-reported life satisfaction. The map here shows, country by country, the ‘happiness scores’ published this report. The underlying source of the happiness scores in the World Happiness Report is the [Gallup World Poll](http://www.gallup.com/services/170945/world-poll.aspx)—a set of nationally representative surveys undertaken in more than 160 countries in over 140 languages. The main life evaluation question asked in the poll is: “Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?” (Also known as the “Cantril Ladder”.) The map plots the average answer that survey-respondents provided to this question in different countries. As with the steps of the ladder, values in the map range from 0 to 10. There are large differences across countries. According to the most recent figures, European countries top the ranking: Finland, Denmark, Iceland, Switzerland and the Netherlands have the highest scores (all with averages above 7). In the same year, the lowest national scores correspond to Afghanistan, Lebanon, Zimbabwe, Rwanda and Botswana (all with average scores below 3.5). You can click on any country on the map to plot time-series for specific countries. As we can see, self-reported life satisfaction correlates with other measures of well-being—richer and healthier countries tend to have higher average happiness scores. (More on this in the section [below](https://ourworldindata.org/happiness-and-life-satisfaction/#correlates-determinants-and-consequences).) <Chart url="https://ourworldindata.org/grapher/happiness-cantril-ladder"/> --- # Happiness over time --- ### Findings from the World Value Survey In addition to the Gallup World Poll (discussed above), the [World Value Survey](http://www.worldvaluessurvey.org/WVSDocumentationWV6.jsp) also provides cross-country data on self-reported life satisfaction. These are the longest available time series of cross-country happiness estimates that include non-European nations. The World Value Survey collects data from a series of representative national surveys covering almost 100 countries, with the earliest estimates dating back to 1981. In these surveys, respondents are asked: “Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy or (iv) Not at all happy”. This visualization plots the share of people answering they are Very happy or Rather happy. As we can see, in the majority of countries the trend is positive: In 49 of the 69 countries with data from two or more surveys, [the most recent observation is higher than the earliest](https://ourworldindata.org/grapher/share-who-say-happy-wvs-first-to-last). In some cases, the improvement has been very large; in Zimbabwe, for example, the share of people who reported being ‘very happy’ or ‘rather happy’ went from 56.4% in 2004 to 82.1% in 2014. <Chart url="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy"/> ### Findings from Eurobarometer The [Eurobarometer](http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/General/index) collects data on life satisfaction as part of their public opinion surveys. For several countries, these surveys have been conducted at least annually for more than 40 years. The visualization here shows the share of people who report being ‘very satisfied’ or ‘fairly satisfied’ with their standards of living, according to this source. Two points are worth emphasizing. First, estimates of life satisfaction often fluctuate around trends. In France, for example, we can see that the overall trend in the period 1974-2016 is positive; yet there is a pattern of ups and downs. And second, despite temporary fluctuations, decade-long trends have been generally positive for most European countries. In most cases, the share of people who say they are ‘very satisfied’ or ‘fairly satisfied’ with their life has gone up over the full survey period.{ref}To be precise, in 27 out of 31 countries with data spanning longer than one decade, the estimate for 2016 is higher than the earliest available estimate.{/ref} Yet there are some clear exceptions, of which Greece is the most notable example. Add Greece to the chart and you can see that in 2007, around 67% of the Greeks said they were satisfied with their life; but five years later, after the financial crisis struck, the corresponding figure was down to 32.4%. Despite recent improvements, Greeks today are on average much less satisfied with their lives than before the financial crisis. No other European country in this dataset has gone through a comparable negative shock. <Chart url="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy-eurobarometer"/> --- # The distribution of life satisfaction --- ### More than averages—the distribution of life satisfaction scores Most of the studies comparing happiness and life satisfaction among countries focus on averages. However, distributional differences are also important. Life satisfaction is often reported on a scale from 0 to 10, with 10 representing the highest possible level of satisfaction. This is the so-called ‘Cantril Ladder’. This visualization shows how responses are distributed across steps in this ladder. In each case, the height of bars is proportional to the fraction of answers at each score. Each differently-colored distribution refers to a world region; and for each region, we have overlaid the distribution for the entire world as a reference. These plots show that in sub-Saharan Africa—the region with the lowest average scores–the distributions are consistently to the left of those in Europe. In economics lingo, we observe that the distribution of scores in European countries _stochastically dominates_ the distribution in sub-Saharan Africa. This means that the share of people who are ‘happy’ is lower in sub-Saharan Africa than in Western Europe, independently of which score in the ladder we use as a threshold to define ‘happy’. Similar comparisons can be made by contrasting other regions with high average scores (e.g. North America, Australia and New Zealand) against those with low average scores (e.g. South Asia). Another important point to notice is that the distribution of self-reported life satisfaction in Latin America is high across the board—it is consistently to the right of other regions with roughly comparable income levels, such as Central and Eastern Europe. This is part of a broader pattern: Latin American countries tend to have a higher subjective well-being than other countries with comparable levels of economic development. As we will see in the section on [social environment](https://ourworldindata.org/happiness-and-life-satisfaction/#the-relationship-between-culture-and-life-satisfaction), culture and history matter for self-reported life satisfaction. <Image filename="The-distribution-of-life-satisfaction.png" alt="Distribution of self-reported life satisfaction by world region"/> If you are interested in data on country-level distributions of scores, the [Pew Global Attitudes Survey](http://www.pewglobal.org/question-search/?qid=365&cntIDs=&stdIDs=) provides such figures for more than 40 countries. --- # (Mis)perceptions about others' happiness --- We tend to underestimate the average happiness of people around us. The visualization shown demonstrates this for countries around the world, using data from Ipsos' [Perils of Perception](http://perils.ipsos.com/)—a cross-country survey asking people to guess what others in their country have answered to the happiness question in the World Value Survey. The horizontal axis in this chart shows the actual share of people who said they are 'Very Happy' or 'Rather Happy' in the World Value Survey; the vertical axis shows the average _guess_ of the same number (i.e. the average guess that respondents made of the share of people reporting to be 'Very Happy' or 'Rather Happy' in their country). If respondents would have guessed the correct share, all observations would fall on the red 45-degree line. But as we can see, all countries are far below the 45-degree line. In other words, people in every country underestimated the self-reported happiness of others. The most extreme deviations are in Asia—South Koreans think that 24% of people report being happy, when in reality 90% do. The highest guesses in this sample (Canada and Norway) are 60%—this is lower than the lowest actual value of self-reported happiness in any country in the sample (corresponding to Hungary at 69%). <Image filename="Happiness-of-others.png" alt=""/> Why do people get their guesses so wrong? It's not as simple as brushing aside these numbers by saying they reflect differences in 'actual' vs. reported happiness. One possible explanation is that people tend to misreport their own happiness, therefore the average guesses might be a correct indicator of true life satisfaction (and an incorrect indicator of _reported_ life satisfaction). However, for this to be true, people would have to commonly misreport their own happiness while assuming that others do _not_ misreport theirs. And people are not bad at judging the well-being of other people who they know: There is substantial evidence showing that [ratings of one's happiness made by friends correlate with one's happiness](https://ourworldindata.org/happiness-and-life-satisfaction/#can-happiness-really-be-measured), and that [people are generally good at evaluating emotions from simply watching facial expressions](https://ourworldindata.org/happiness-and-life-satisfaction/#how-much-does-language-matter-for-cross-country-comparisons-of-happiness). An alternative explanation is that this mismatch is grounded in the well-established fact that people tend to be positive about themselves, but negative about other people they don't know.It has been observed in other contexts that people can be optimistic about their own future, while at the same time being deeply pessimistic about the future of their nation or the world. We discuss this phenomenon in more detail in our entry on [optimism and pessimism](https://ourworldindata.org/optimism-pessimism/), specifically in a section dedicated to [individual optimism and social pessimism](https://ourworldindata.org/optimism-pessimism/#individual-optimism-and-social-pessimism). --- # Differences in happiness within countries --- ## East and West Germany In global surveys of happiness and life satisfaction, [Germany usually ranks high](https://ourworldindata.org/grapher/happiness-cantril-ladder). However, these national averages mask large inequalities. In the map shown we focus on regional inequalities—specifically the gap in life satisfaction between West and East Germany. This map plots self-reported life satisfaction in Germany (using the [0-10 Cantril Ladder question](https://ourworldindata.org/happiness-and-life-satisfaction/#is-life-satisfaction-the-same-as-happiness)), aggregating averages scores at the level of [Federal States](https://en.wikipedia.org/wiki/States_of_Germany).{ref}In some cases, the underlying data had multiple average estimates for the same territory (e.g. Baden and Württemberg were treated as different entities). In these cases the map shows the average between these two observations. Details can be found in [this file](https://ourworldindata.org/app/uploads/2017/04/Germany-happiness-data.xlsx){/ref} What stands out is a clear divide between the East and the West, along the political division that existed before the reunification of Germany in 1990. For example, the difference in levels between neighboring Schleswig-Holstein (in West Germany) and Mecklenburg-Vorpommern (in East Germany) are similar to the difference between [Sweden and the US](https://ourworldindata.org/grapher/happiness-cantril-ladder) – a considerable contrast in self-reported life satisfaction. <Image filename="Germany-happiness-Gluecksatlas.png" alt=""/> Several academic studies have looked more closely at this 'happiness gap' in Germany using data from more detailed surveys, such as the German Socio-Economic Panel (e.g. Petrunyk and Pfeifer 2016).{ref}Petrunyk, I., & Pfeifer, C. (2016). Life satisfaction in Germany after reunification: Additional insights on the pattern of convergence. Jahrbücher für Nationalökonomie und Statistik, 236(2), 217-239.{/ref} These studies provide two main insights: First, the gap is partly driven by differences in household income and employment. But this is not the only aspect; even after controlling for socioeconomic and demographic differences, the East-West gap remains significant. ### Germany's happiness gap over time And second, the gap has been narrowing in recent years, as the chart shows. In fact, the finding that the gap is narrowing is true both for the raw average differences, as well as for the 'conditional differences' (i.e. the differences that are estimated after controlling for socioeconomic and demographic characteristics). ##### Trends in life satisfaction for East and West Germany, 1992-2013 <Image filename="East-West-German-Happiness-gaps-Petrunyk-and-Pfeifer-2016.png" alt=""/> The observation that socioeconomic and demographic differences do not fully predict the observed East-West differences in self-reported happiness is related to a broader empirical phenomenon: Culture and history matter for self-reported life satisfaction—and in particular, ex-communist countries tend to have a lower subjective well-being than other countries with comparable levels of economic development. ## Happiness inequality ### Happiness inequality in the US and other rich countries The General Social Survey (GSS) in the US is a survey administered to a nationally representative sample of about 1,500 respondents each year since 1972, and is an important source of information on long-run trends of self-reported life satisfaction in the country.{ref}The GSS asks people a very similar question to the World Value Survey: “Taken all together, how would you say things are these days—would you say that you are very happy, pretty happy, or not too happy?”{/ref} Using this source, Stevenson and Wolfers (2008){ref}Stevenson, Betsey, and Justin Wolfers. “Happiness inequality in the United States.” The Journal of Legal Studies 37.S2 (2008): S33-S79. An ungated earlier version of the paper is available [here](https://www.econstor.eu/bitstream/10419/35143/1/576953326.pdf).{/ref} show that while the national average has remained broadly constant, inequality in happiness has fallen substantially in the US in recent decades. The authors further note that this is true both when we think about inequality in terms of the dispersion of answers, and also when we think about inequality in terms of gaps between demographic groups. They note that two-thirds of the black-white happiness gap has been eroded (although today white Americans remain happier on average, even after controlling for differences in education and income), and the gender happiness gap has disappeared entirely (women used to be slightly happier than men, but they are becoming less happy, and today there is no statistical difference once we control for other characteristics).{ref}These results have been discussed in various blogs. Freakonomics provides a quick and interesting overview of the debate, specifically with regard to [gender gaps](http://freakonomics.com/2007/10/01/why-are-women-so-unhappy/).{/ref} The results from Stevenson and Wolfers are consistent with other studies looking at changes of happiness inequality (or life satisfaction inequality) over time. In particular, researchers have noted that there is a correlation between economic growth and reductions in happiness inequality—even when [income inequality](https://ourworldindata.org/income-inequality/) is increasing at the same time. The visualization here uses data from Clark, Fleche and Senik (2015){ref}Clark, Andrew E., Sarah Flèche, and Claudia Senik. “Economic growth evens out happiness: Evidence from six surveys.” Review of Income and Wealth (2015). An ungated earlier version of the paper is available [here](http://eprints.lse.ac.uk/60530/1/dp1306.pdf){/ref} shows this. It plots the evolution of happiness inequality within a selection of rich countries that experienced uninterrupted GDP growth. In this chart, happiness inequality is measured by the dispersion — specifically the standard deviation — of answers in the World Value Survey. As we can see, there is a broad negative trend. In their paper the authors show that the trend is positive in countries with falling GDP. <Chart url="https://ourworldindata.org/grapher/evolution-of-happiness-inequality-within-countries-during-periods-of-uninterrupted-economic-growth"/> Why could it be that happiness inequality falls with rising income inequality? Clark, Fleche, and Senik argue that part of the reason is that the growth of national income allows for the greater provision of public goods, which in turn tighten the distribution of subjective well-being. This can still be consistent with growing income inequality, since public goods such as [better health](https://ourworldindata.org/health-meta/) affect incomes and well-being differently. Another possibility is that economic growth in rich countries has translated into a more diverse society in terms of cultural expressions (e.g. through the emergence of alternative lifestyles), which has allowed people to converge in happiness even if they diverge in incomes, tastes and consumption. Steven Quartz and Annette Asp explain this hypothesis in a [New York Times article](https://www.nytimes.com/2015/04/12/opinion/sunday/unequal-yet-happy.html?smid=nytcore-ipad-share&smprod=nytcore-ipad&_r=0), discussing evidence from experimental psychology. --- # The link between happiness and income --- ## The link across countries ### Higher national incomes go together with higher average life satisfaction If we compare life satisfaction reports from around the world at any given point in time, we immediately see that countries with higher average national incomes tend to have higher average life satisfaction scores. In other words: People in richer countries tend to report higher life satisfaction than people in poorer countries. The scatter plot here shows this. Each dot in the visualization represents one country. The vertical position of the dots shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction); while the horizontal position shows GDP per capita based on purchasing power parity (i.e. GDP per head after adjusting for inflation and cross-country price differences). This correlation holds even if we control for other factors: Richer countries tend to have higher average self-reported life satisfaction than poorer countries that are comparable in terms of demographics and other measurable characteristics. You can read more about this in the [World Happiness Report 2017](http://worldhappiness.report/), specifically the discussion in Chapter 2. As we show below, income and happiness also tend to go together [within countries](https://ourworldindata.org/happiness-and-life-satisfaction/#higher-personal-incomes-go-together-with-higher-self-reported-life-satisfaction) and [across time](https://ourworldindata.org/happiness-and-life-satisfaction/#economic-growth-and-happiness). <Chart url="https://ourworldindata.org/grapher/gdp-vs-happiness"/> ## The link within countries ### Higher personal incomes go together with higher self-reported life satisfaction Above we point out that richer countries tend to be happier than poorer countries. Here we show that the same tends to be true within countries: richer people within a country tend to be happier than poorer people in the same country. The visualisations here show us this this by looking at happiness by income quintiles. Firstly we show each country in individual panels: within each panel is a connected scatter plot for a specific country. This means that for each country, we observe a line joining five points: each point marks the average income within an income quintile (horizontal axis) against the average self-reported life satisfaction of people at that income quintile (vertical axis). What does this visualization tell us? We see that in all cases lines are upward sloping: people in higher income quintiles tend to have higher average life satisfaction. Yet in some countries the lines are steep and linear (e.g. in Costa Rica richer people are happier than poorer people across the whole income distribution); while in some countries the lines are less steep and non-linear (e.g. the richest group of people in the Dominican Republic is as happy as the second-richest group). <Image filename="Happiness-by-Income-Quintiles-Small-Multiples.png" alt="Self-reported life-satisfaction across the income distribution"/> In a second visualization we present the same data, but instead of plotting each country separately, showing all countries in one grid. The resulting connected scatter plot may be messy, resembling a ‘spaghetti’ chart, but it is helpful to confirm the overall pattern: despite kinks here and there, lines are by and large upward sloping. <Image filename="Happiness-across-income-distribution.png" alt="Self-reported life satisfactino across the income distribution, country by country"/> ## Looking across and within countries ### A snapshot of the correlation between income and happiness—between and within countries Do income and happiness tend to go together? The visualization here shows that the answer to this question is yes, both within and across countries. It may take a minute to wrap your head around this visualization, but once you do, you can see that it handily condenses the key information from the previous three charts into one. To show the income-happiness correlation across countries, the chart plots the relationship between self-reported life satisfaction on the vertical axis and GDP per capita on the horizontal axis. Each country is an arrow on the grid, and the location of the arrow tells us the corresponding combination of average income and average happiness. To show the income-happiness correlation _within_ countries, each arrow has a slope corresponding to the correlation between household incomes and self-reported life satisfaction within that country. In other words: the slope of the arrow shows how strong the relationship between income and life satisfaction is within that country. ([This chart](https://ourworldindata.org/app/uploads/2013/05/South-Africa-inequality-of-income-and-happiness-as-example.png) gives you a visual example of how the arrows were constructed for each country). {ref}To be precise, the gradients correspond, country by country, to the regression coefficients between income quintiles and the related average life satisfaction reported by people within each income quintile.{/ref} If an arrow points northeast, that means richer people tend to report higher life satisfaction than poorer people in the same country. If an arrow is flat (i.e. points east), that means rich people are on average just as happy as poorer people in the same country. As we can see, there is a very clear pattern: richer countries tend to be happier than poorer countries (observations are lined up around an upward-sloping trend), and richer people within countries tend to be happier than poorer people in the same countries (arrows are consistently pointing northeast). <Image filename="GDP-vs-Happiness-and-gradient-within-countries.png" alt="People in richer countries tend to be happier and within all countries richer people tend to be happier"/> It’s important to note that the horizontal axis is measured in a logarithmic scale. The cross-country relationship we would observe in a linear scale would be different, since at high national income levels, slightly higher national incomes are associated with a smaller increase in average happiness than at low levels of national incomes. In other words, the cross-country relationship between income and happiness is not linear on income (it is ‘log-linear’). We use the logarithmic scale to highlight two key facts: (i) at no point in the global income distribution is the relationship flat; and (ii) a doubling of the average income is associated with roughly the same increase in the reported life-satisfaction, irrespective of the position in the global distribution. These findings have been explored in more detail in a number of recent academic studies. Importantly, the much-cited paper by Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online [here](https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF). {/ref} shows that these correlations hold even after controlling for various country characteristics such as demographic composition of the population, and are robust to different sources of data and types of subjective well-being measures. ## Economic growth and happiness In the charts above we show that there is robust evidence of a strong correlation between income and happiness across and within countries at fixed points in time. Here we want to show that, while less strong, there is also a correlation between income and happiness across time. Or, put differently, as countries get richer, the population tends to report higher average life satisfaction. The chart shown here uses data from the World Value Survey to plot the evolution of national average incomes and national average happiness over time. To be specific, this chart shows the share of people who say they are ‘very happy’ or ‘rather happy’ in the World Value Survey (vertical axis), against GDP per head (horizontal axis). Each country is drawn as a line joining first and last available observations across all survey waves.{ref}The dataset includes observations for Egypt. However, we have excluded these observations from our analysis. This is because the survey for Egypt in the wave labeled 2014 is from 2012, which was a year characterized by extreme political instability in that country.{/ref} As we can see, countries that experience economic growth also tend to experience happiness growth across waves in the World Value Survey. And this is a correlation that holds after controlling for other factors that also change over time (in [this chart](https://ourworldindata.org/app/uploads/2017/04/Stevenson-Wolfers-2008-%E2%80%93-Happiness-and-Growth-744x550.png) from Stevenson and Wolfers (2008) you can see how changes in GDP per capita compare to changes in life satisfaction after accounting for changes in demographic composition and other variables). An important point to note here is that economic growth and happiness growth tend to go together _on average_. Some countries in some periods experience economic growth without increasing happiness. The experience of the US in recent decades is a case in point. These instances may seem paradoxical given the evidence—we explore this question in the following section. <Image filename="Inc-vs-Happiness-over-time.png" alt=""/> ## The Easterlin Paradox The observation that economic growth does not always go together with increasing life satisfaction was first made by Richard Easterlin in the 1970s. Since then, there has been much discussion over what came to be known as the ‘Easterlin Paradox’. At the heart of the paradox was the fact that richer countries tend to have higher self-reported happiness, yet in some countries for which repeated surveys were available over the course of the 1970s, happiness was not increasing with rising national incomes. This combination of empirical findings was paradoxical because the cross-country evidence (countries with higher incomes tended to have higher self-reported happiness) did not, in some cases, fit the evidence over time (countries seemed not to get happier as national incomes increased). Notably, Easterlin and other researchers relied on data from the US and Japan to support this seemingly perplexing observation. If we look closely at the data underpinning the trends in these two countries, however, these cases are not in fact paradoxical. Let us begin with the case of Japan. There, the earliest available data on self-reported life satisfaction came from the so-called ‘Life in Nation surveys’, which date back to 1958. At first glance, this source suggests that mean life satisfaction remained flat over a period of spectacular economic growth (see for example [this chart](http://ourworldindata.org/app/uploads/2013/05/mean-subjective-well-being-japan-1958-1987-easterlin-in-land-michalos-and-sirgy-ed-2011.png) from Easterlin and Angelescu 2011).{ref}R.A. Easterlin and L. Angelescu – ‘Modern Economic Growth and Quality of Life: Cross-Sectional and Time Series Evidence’ in Land, Michalos, and Sirgy (ed.) (2011) – Handbook of Social Indicators and Quality of Life Research. Springer.{/ref} Digging a bit deeper, however, we find that things are more complex. Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online [here](https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF). {/ref} show that the life satisfaction questions in the ‘Life in Nation surveys’ changed over time, making it difficult—if not impossible—to track changes in happiness over the full period. The visualization here splits the life satisfaction data from the surveys into sub-periods where the questions remained constant. As we can see, the data is not supportive of a paradox: the correlation between GDP and happiness growth in Japan is positive within comparable survey periods. The reason for the alleged paradox is in fact mismeasurement of how happiness changed over time. In the US, the explanation is different, but can once again be traced to the underlying data. Specifically, if we look more closely at economic growth in the US over the recent decades, one fact looms large: growth has not benefitted the majority of people. Income inequality in the US is exceptionally high and has been on the rise in the last four decades, with incomes for the median household growing much more slowly than incomes for the top 10%. As a result, trends in aggregate life satisfaction should not be seen as paradoxical: the income and standard of living of the typical US citizen has not grown much in the last couple of decades. (You can read more about this in our entry on [inequality and incomes across the distribution](https://ourworldindata.org/incomes-across-the-distribution/#the-us-incomes-for-most-households-stagnate-inequality-increases-constantly).) ##### [](undefined)GDP per capita vs Life satisfaction across survey questions, Japan, 1958-2007 – Stevenson and Wolfers (2008){ref}Chart from Stevenson B, Wolfers J (2008) - Economic Growth and Subjective Well-Being: Reassessing the Easterlin Paradox. Brookings Paper Econ Activ 2008 (Spring):1–87. Underlying data source: Life in Nation surveys, 1958–2007.

In this visualization, we provide evidence of the cross-country relationship. Each dot in the scatterplot represents one country. The vertical position of the dots shows national life expectancy at birth, and the horizontal position shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction). As we can see, there is a strong positive correlation: countries where people tend to live longer are also countries where people tend to say more often that they are satisfied with their lives. A similar relationship holds for other health outcomes (e.g. [life satisfaction tends to be higher in countries with lower child mortality](https://ourworldindata.org/grapher/life-satisfaction-vs-child-mortality)). The relationship plotted in the chart clearly reflects more than just the link between health and happiness, since countries with high life expectancy also tend to be countries with many other distinct characteristics. However, the positive correlation between life expectancy and life satisfaction remains after controlling for observable country characteristics, such as incomes and social protection. You can read more about this in the [World Happiness Report 2017](http://worldhappiness.report/), specifically the discussion in Chapter 2. <Chart url="https://ourworldindata.org/grapher/life-satisfaction-vs-life-expectancy"/> ## Mental health and happiness When trying to discern a relationship between [mental health](https://owid.cloud/mental-health) and happiness, it is important to distinguish between macro and micro-level correlations. When we look at macro-level, [cross-country trends](https://ourworldindata.org/grapher/depression-vs-self-reported-life-satisfaction) in the prevalence of mental health disorders such as depression versus self-reported life satisfaction there is no clear relationship: it does not appear that countries with higher depression rates have lower self-reported happiness. However, when we look at micro-level, within-country correlations the data tells a different story. In this visualization, we provide evidence of the relationship between health and subjective well-being within countries—specifically; we focus here on mental health and self-reported life satisfaction. Each bar in the visualization measures the extent to which mental illness (depression and anxiety) is associated with self-reported life satisfaction, once we control for physical illness and other factors such as income and education. In other words, the bars show a ‘conditional correlation’—the strength of the link between mental illness and happiness after accounting for other factors. The negative values show that people who have been diagnosed with depression or anxiety tend to be more likely to have lower self-reported life satisfaction. The size of the coefficients, particularly in the US, and Australia, tell us that the relationship we observe is very strong. For context, in the UK, the US and Australia the magnitude of the correlation between mental illness and life satisfaction is [higher than the magnitude for the correlation between income and life satisfaction](https://ourworldindata.org/grapher/correlation-income-and-life-satisfaction). Clearly, this correlation is likely the result of a two-way relationship: depressed and anxious people are less likely to be happy, and unhappy people are more likely to be depressed or anxious. Nevertheless, it is still important to bear in mind that anxiety, depression and unhappiness often go together. Other studies provide further evidence of not only the negative correlation between depression and life satisfaction (i.e individuals with more severe depression report lower life satisfaction), but also evidence that treatment and improvement in depression are linked to increases in self-reported life satisfaction.{ref}Koivumaa‐Honkanen, H., Honkanen, R., Antikainen, R., Hintikka, J., Laukkanen, E., Honkalampi, K., & Viinamäki, H.

When asked to visualize happy and sad situations, researchers found individuals with depression to show notably less facial muscle activity relative to those without - a suggestion sign of both lower emotivity and disengagement.{ref}Gehricke, J.

The Economic Journal, 118(529).{/ref} use data from the German Socio-Economic Panel to identify groups of people experiencing significant life and labour market events, and trace how these events affect the evolution of their life satisfaction. The visualization here shows an overview of their main findings. In each individual chart, the red lines mark the estimated effect of a different event at a given point in time (with ‘whiskers’ marking the range of confidence of each estimate). In all cases the results are split by gender, and time is labeled so that 0 marks the point when the corresponding event took place (with negative and positive values denoting years before and after the event). All estimates control for individual characteristics, so the figures show the effect of the event after controlling for other factors (e.g. income, etc.). The first point to note is that most events denote the evolution of a latent situation: People grow unhappy in the period building up to a divorce, while they grow happy in the period building up to a marriage. The second point is that single life events do tend to affect happiness in the short run, but people often adapt to changes. Of course, there are clear differences in the extent to which people adapt. In the case of divorce, life satisfaction first drops, then goes up and stays high. For unemployment, there is a negative shock both in the short and long-run, notably among men. And for marriage, life satisfaction builds up before, and fades out after the wedding. In general, the evidence suggests that adaptation is an important feature of well-being. Many common but important life events have a modest long-term impact on self-reported happiness. Yet adaptation to some events, such as long-term unemployment, is neither perfect nor immediate. <Image filename="Life-events-on-happiness.png" alt="The effect of life events on life satisfaction"/> ## Does disability correlate with life satisfaction? A number of papers have noted that long-term paraplegics do not report themselves as particularly unhappy, when compared to non-paraplegics (see for example the much-cited paper by Brickman, Coates, and Janoff-Bulman, 1978).{ref} Brickman, P., Coates, D., & Janoff-Bulman, R. (1978). Lottery winners and accident victims: Is happiness relative?. Journal of personality and social psychology, 36(8), 917. Chicago. Available online [here](https://static1.squarespace.com/static/54694fa6e4b0eaec4530f99d/t/54c6fbbae4b057e0ac944d2e/1422326714627/Lottery+winners+and+Accident+Victims.pdf).{/ref} This assertion has received attention because it tells us something about the very meaning of well-being and has important consequences for policy. It is, for example, considered in courts of law with respect to the compensation for disability. However, comparing differences in self-reported life satisfaction among people with different disability statuses is not an ideal source of evidence regarding the effect of tragedy on happiness. Non-paraplegics are potentially different to paraplegics in ways that are hard to measure. A better source of evidence are longitudinal surveys where people are tracked over time. Oswald and Powdthavee (2008){ref}Oswald, A. J., & Powdthavee, N. (2008). Does happiness adapt? A longitudinal study of disability with implications for economists and judges. Journal of public economics, 92(5), 1061-1077.{/ref} use data from a longitudinal survey in the UK to explore whether accidents leading to disability imply long-term shocks to life satisfaction. The chart here, from Oswald and Powdthavee, shows the average reported life satisfaction of a group of people who became seriously disabled (at time T) and remained seriously disabled in the two following years (T+1 and T+2). Here, ‘seriously disabled’ means that disability prevented them from being able to do day-to-day activities. As we can see—and as the authors show more precisely through econometric techniques—those entering disability suffer a sudden drop in life satisfaction, and recover only partially. This supports the idea that while adaptation plays a role for common life events, the notion of life satisfaction is indeed sensitive to tragic events. ##### [](undefined)Life satisfaction of those entering serious disability, BHPS 1996-2002 – Oswald and Powdthavee (2006) <Image filename="Disability-and-happiness-Oswald-and-Powdthavee-2006.png" alt="Life satisfaction of those entering serious disability"/> --- # Life satisfaction and society --- ## Culture and life satisfaction Comparisons of happiness among countries suggest that culture and history shared by people in a given society matter for self-reported life satisfaction. For example, as the chart here shows, culturally and historically similar Latin American countries have a higher subjective well-being than other countries with comparable levels of economic development. (This chart plots self-reported life satisfaction as measured in the 10-point Cantril ladder in the vertical axis, against GDP per capita in the horizontal axis). Latin America is not a special case in this respect. Ex-communist countries, for example, tend to have lower subjective well-being than other countries with comparable characteristics and levels of economic development. Academic studies in positive psychology discuss other patterns. Diener and Suh (2002) write: “In recent years cultural differences in subjective well-being have been explored, with a realization that there are profound differences in what makes people happy. Self-esteem, for example, is less strongly associated with life satisfaction, and extraversion is less strongly associated with pleasant affect in collectivist cultures than in individualist cultures”.{ref}Diener, E., Oishi, S., & Lucas, R. E. (2009). Subjective well-being: The science of happiness and life satisfaction. Oxford handbook of positive psychology, 2, 187-194.{/ref} To our knowledge, there are no rigorous studies exploring the causal mechanisms linking culture and happiness. However, it seems natural to expect that cultural factors shape the way people collectively understand happiness and the meaning of life. <Image filename="continent-version-GDP-pc-vs-Happiness-By-culture.png" alt="Self-reported life satisfaction vs GDP per capita, in 2015"/> ## Sense of freedom and life satisfaction A particular channel through which social environment may affect happiness is freedom: the society we live in may crucially affect the availability of options that we have to shape our own life. This visualization shows the relationship between self-reported sense of freedom and self-reported life satisfaction using data from the [Gallup World Poll](http://www.gallup.com/services/170945/world-poll.aspx). The variable measuring life satisfaction corresponds to country-level averages of survey responses to the Cantril Ladder question (a 0-10 scale, where 10 is the highest level of life satisfaction); while the variable measuring freedom corresponds to the share of people who agree with the statement “In this country, I am satisfied with my freedom to choose what I do with my life”.{ref}To be precise, the Gallup World Poll asks: “In this country, are you satisfied or dissatisfied with your freedom to choose what you do with your life?”{/ref} As we can see, there is a clear positive relationship: countries where people feel free to choose and control their lives tend to be countries where people are happier. As Inglehart et al. (2008){ref}Inglehart, R., Foa, R., Peterson, C., & Welzel, C. (2008). Development, freedom, and rising happiness: A global perspective (1981–2007). Perspectives on psychological science, 3(4), 264-285.{/ref} show, this positive relationship holds even after we control for other factors, such as incomes and strength of religiosity. Interestingly, this chart also shows that while there are some countries where the perceived sense of freedom is high but average life satisfaction is low (e.g. Rwanda); there are no countries where the perceived sense of freedom is low but average life satisfaction is high (i.e. there are no countries in the top left area of the chart). To our knowledge there are no rigorous studies exploring the causal mechanisms linking freedom and happiness. However, it seems natural to expect that self-determination and absence of coercion are important components of what people consider a happy and meaningful life. <Image filename="Happiness-vs-Freedom-in-Your-Life.png" alt="Perception of freedom vs self-reported life satisfaction, 2016"/> ## The link between media and gloominess A number of studies have found that there is a link between emotional exposure to negative content in news and changes in mood. Johnston and Davey (1997),{ref} Johnston, W. M., & Davey, G. C. (1997). The psychological impact of negative TV news bulletins: The catastrophizing of personal worries. British Journal of Psychology, 88(1), 85-91.{/ref} for example, conducted an experiment in which they edited short TV news to display positive, neutral or negative material, and then showed them to three different groups of people. The authors found that people who watched the ‘negative’ clip were more likely to report a sad mood. This link between emotional content in news and changes in mood is all the more important if we consider that media gatekeepers tend to prefer negative to positive coverage of newsworthy facts (see, for example, Combs and Slovic 1979{ref} Combs, B., & Slovic, P. (1979). Newspaper coverage of causes of death. Journalism Quarterly, 56(4), 837-849.{/ref}). Of course, mood is not the same as life satisfaction. Yet, as we discuss below in the [section on measurement and data quality](https://ourworldindata.org/happiness-and-life-satisfaction/#data-quality-and-measurement), surveys measuring happiness often do capture emotional aspects of well-being. And in any case, people’s perceptions of what it means to lead a meaningful life are heavily influenced by their expectations of what is possible and likely to occur with their lives; and this has also been shown to depend on media exposure.{ref}Riddle (2010), for example, found that people watching more vivid violent media gave higher estimates of the prevalence of crime in the real world. (Riddle, 2010, “Always on my mind: Exploring how frequent, recent, and vivid television portrayals are used in the formation of social reality judgments.” Media Psychology.) {/ref} --- # Data Quality and Measurement --- ## Can ‘happiness’ really be measured? The most natural way to attempt to measure subjective well-being is to ask people what they think and feel. Indeed, this is the most common approach. In practice, social scientists tend to rely on questions inquiring directly about happiness, or on questions inquiring about life satisfaction. The former tend to measure the experiential or emotional aspects of well-being (e.g. “I feel very happy”), while the latter tend to measure the evaluative or cognitive aspects of well-being (e.g. “I think I lead a very positive life”). Self-reports about happiness and life satisfaction are known to correlate with things that people typically associate with contentment, such as cheerfulness and smiling. (In [this scatter plot](https://ourworldindata.org/app/uploads/2017/04/Life-Satisfaction-vs-Laugh-Gallup.png) you can see that countries where people have higher self-reported life satisfaction are also countries where people tend to smile more). Experimental psychologists have also shown that self reports of well-being from surveys turn out to correlate with activity in the parts of the brain associated with pleasure and satisfaction. And various surveys have confirmed that people who say they are happy also tend to sleep better and express positive emotions verbally more frequently. The following table, adapted from Kahneman and Krueger (2006){ref}Kahneman, D., & Krueger, A. B. (2006). Developments in the measurement of subjective well-being. The journal of economic perspectives, 20(1), 3-24.{/ref}, provides a list of the variables that researchers have found to be related to self-reported happiness and life satisfaction. The main conclusion from the evidence is that survey-based measures of happiness and life satisfaction do provide a reasonably consistent and reliable picture of subjective well-being. <div class="raw-html-table__container"><table><thead><tr><th scope="col" colspan="1"><div style="float: left;"> Correlates of high life satisfaction and happiness</div></th></tr></thead><tbody><tr><td colspan="1" rowspan="1"><div style="float: left;">Smiling frequency</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Smiling with the eyes ("unfakeable smile") </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Ratings of one's happiness made by friends</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Frequent verbal expressions of positive emotions </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Sociability and extraversion</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Sleep quality </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Happiness of close relatives </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Self-reported health </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;"> High income, and high income rank in a reference group </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;"> Active involvement in religion</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;"> Recent positive changes of circumstances (increased income, marriage) </div></td></tr></tbody></table></div> ## Is ‘life satisfaction’ the same as ‘happiness’? In this entry we discuss data and empirical research on happiness and life satisfaction. However, it is important to bear in mind that “life satisfaction” and “happiness” are not really synonyms. And this is of course reflected in the data, since self-reported measures of these two variables come from asking different kinds of questions. The World Value Survey asks directly about happiness: _“Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy, (iv) Not at all happy, (v) Don’t know.”_ The Gallup World Poll, on the other hand, uses the Cantril Ladder question and asks respondents to evaluate their life: _“Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?”_ As the following scatter plot shows, these two measures are clearly closely related (countries that score high in one measure also tend to score high in the other), yet they are not identical (there is substantial dispersion, with many countries sharing the same score in one variable but diverging in the other). The differences in responses to questions inquiring about life satisfaction and happiness are consistent with the idea that subjective well-being has two sides: an experiential or emotional side, and an evaluative or cognitive side. Of course, the limits between emotional and cognitive aspects of well-being are blurred in our minds; so in practice both kinds of questions measure both aspects to some degree. Indeed, social scientists often construct ‘subjective well-being indexes’ where they simply average out results from various types of questions. <Chart url="https://ourworldindata.org/grapher/Happiness-WVS-vs-Gallup"/> ## Are happiness averages really meaningful? The most common way to analyze data on happiness consists in taking averages across groups of people. Indeed, cross-country comparisons of self-reported life satisfaction, such as those presented in ‘happiness rankings’, rely on national averages of reports on a scale from 0 to 10 (the Cantril Ladder). Is it reasonable to take averages of life satisfaction scores? Or, in more technical terms: are self reports of Cantril scores really a cardinal measure of well-being? The evidence tells us that survey-based reports on the Cantril Ladder do allow cardinal measurement reasonably well—respondents have been found to translate verbal labels, such as ‘very good’ and ‘very bad’, into roughly the same numerical values.{ref}Ferrer‐i‐Carbonell, A., & Frijters, P. (2004). How important is methodology for the estimates of the determinants of happiness?. The Economic Journal, 114(497), 641-659.{/ref} {ref}Van Praag, B.M.S. (1991). ‘Ordinal and cardinal utility: an integration of the two dimensions of the welfare concept’, Journal of Econometrics, vol. 50, pp. 69–89.{/ref} But as with any other aggregate indicator of social progress, averages need to be interpreted carefully, even if they make sense arithmetically. For example, if we look at happiness by age in a given country, we may see that older people do not appear to be happier than younger people. Yet this may be because the average-by-age figure from the snapshot confounds two factors: the age effect (people from the same cohort do get happier as they grow older, across all cohorts) and the cohort effect (across all ages, earlier generations are less happy than more recent generations). If the cohort effect is very strong, the snapshot can even give a picture that suggests people become _less_ happy as they grow older, even though the exact opposite is actually true within all generations. This example is in fact taken from the real world: using data from the US, Sutin et al. (2013){ref}Sutin, A. R., Terracciano, A., Milaneschi, Y., An, Y., Ferrucci, L., & Zonderman, A. B. (2013). The effect of birth cohort on well-being The legacy of economic hard times. Psychological science, 0956797612459658.{/ref} showed that self-reported feelings of well-being tend to increase with age across generations, but overall levels of well-being depend on when people were born. ### How much does language matter for cross-country comparisons of happiness? Linguistic differences are often seen as a major obstacle for making cross-country comparisons of happiness. However, there is evidence suggesting that comparability issues, at least in respect to language, are less problematic than many people think. Studies have shown, for example, that in interviews in which respondents are shown pictures or videos of other individuals, respondents can broadly identify whether the individual shown to them was happy or sad; and this is also true when respondents were asked to predict the evaluations of individuals from other cultural communities. (For evidence of this see Sandvik et al., 1993; Diener and Lucas, 1999).{ref}Sandvik, E., Diener, E. and Seidlitz, L. (1993). ‘Subjective well-being: the convergence and stability of self and non self report measures’, Journal of Personality, vol. 61, pp. 317–42. Diener, E. and Lucas, R.E. (1999). ‘Personality and subjective well-being’, in Kahneman et al. (1999) chapter 11.{/ref} Studies have also shown that ‘indigenous emotions’ across cultures (i.e. feelings that are unique in that they do not have equivalents in the English language) are not experienced any more frequently or differently than common translated emotions. (See Scollon et al. 2005).{ref}Scollon, C. N., Diener, E., Oishi, S., & Biswas-Diener, R. (2004). Emotions across cultures and methods. Journal of cross-cultural psychology, 35(3), 304-326.{/ref} The conclusion, therefore, seems to be that there is some basic understanding among humans about what it means to be ‘happy’. Survey-based measures of self-reported life satisfaction are informative about cross-country differences, even if these comparisons are obviously noisy. --- # Data Sources --- ### Cross-country estimates ### [](undefined)World Happiness Report * Data: Country averages of self-reported life satisfaction (Question: Cantril Ladder). * Underlying source: Gallup World Poll * Time span: 2005-2022 * Available at:[World Happiness Report](http://worldhappiness.report/) ### [](undefined)European Commission – Eurobarometer Interactive * Data: Life satisfaction (Question: _“On the whole are you very satisfied, fairly satisfied, not very satisfied or not at all satisfied with the life you lead ?”_) * Geographical coverage: EU countries * Time span: 1973 - 2015 * Available at:[http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index](http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index) ### [](undefined)The World Value Survey (WVS) * Data: Happiness and life satisfaction, as well as many other social and cultural characteristics from cross-national time-series surveys.

The main life evaluation question asked in the poll is: \u201cPlease imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?\u201d (Also known as the \u201cCantril Ladder\u201d.)</p>\n\n\n\n<p>The map plots the average answer that survey-respondents provided to this question in different countries. As with the steps of the ladder, values in the map range from 0 to 10.</p>\n\n\n\n<p>There are large differences across countries. According to the most recent figures, European countries top the ranking: Finland, Denmark, Iceland, Switzerland and the Netherlands have the highest scores (all with averages above 7).

This visualization plots the share of people answering they are Very happy or Rather happy.</p>\n\n\n\n<p>As we can see, in the majority of countries the trend is positive: In 49 of the 69 countries with data from two or more surveys, <a href=\"https://ourworldindata.org/grapher/share-who-say-happy-wvs-first-to-last\">the most recent observation is higher than the earliest</a>. In some cases, the improvement has been very large; in Zimbabwe, for example, the share of people who reported being \u2018very happy\u2019 or \u2018rather happy\u2019 went from 56.4% in 2004 to 82.1% in 2014.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h4>Findings from Eurobarometer</h4>\n\n\n\n<p>The <a href=\"http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/General/index\">Eurobarometer</a> collects data on life satisfaction as part of their public opinion surveys. For several countries, these surveys have been conducted at least annually for more than 40 years. The visualization here shows the share of people who report being \u2018very satisfied\u2019 or \u2018fairly satisfied\u2019 with their standards of living, according to this source.</p>\n\n\n\n<p>Two points are worth emphasizing. First, estimates of life satisfaction often fluctuate around trends. In France, for example, we can see that the overall trend in the period 1974-2016 is positive; yet there is a pattern of ups and downs. And second, despite temporary fluctuations, decade-long trends have been generally positive for most European countries.</p>\n\n\n\n<p>In most cases, the share of people who say they are \u2018very satisfied\u2019 or \u2018fairly satisfied\u2019 with their life has gone up over the full survey period.{ref}To be precise, in 27 out of 31 countries with data spanning longer than one decade, the estimate for 2016 is higher than the earliest available estimate.{/ref} Yet there are some clear exceptions, of which Greece is the most notable example. Add Greece to the chart and you can see that in 2007, around 67% of the Greeks said they were satisfied with their life; but five years later, after the financial crisis struck, the corresponding figure was down to 32.4%. Despite recent improvements, Greeks today are on average much less satisfied with their lives than before the financial crisis. No other European country in this dataset has gone through a comparable negative shock.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy-eurobarometer\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h2>The distribution of life satisfaction</h2>\n\n\n\n<h4>More than averages\u2014the distribution of life satisfaction scores</h4>\n\n\n\n<p>Most of the studies comparing happiness and life satisfaction among countries focus on averages. However, distributional differences are also important.</p>\n\n\n\n<p>Life satisfaction is often reported on a scale from 0 to 10, with 10 representing the highest possible level of satisfaction. This is the so-called \u2018Cantril Ladder\u2019. This visualization shows how responses are distributed across steps in this ladder. In each case, the height of bars is proportional to the fraction of answers at each score. Each differently-colored distribution refers to a world region; and for each region, we have overlaid the distribution for the entire world as a reference.</p>\n\n\n\n<p>These plots show that in sub-Saharan Africa\u2014the region with the lowest average scores\u2013the distributions are consistently to the left of those in Europe. In economics lingo, we observe that the distribution of scores in European countries <em>stochastically dominates</em> the distribution in sub-Saharan Africa.</p>\n\n\n\n<p>This means that the share of people who are \u2018happy\u2019 is lower in sub-Saharan Africa than in Western Europe, independently of which score in the ladder we use as a threshold to define \u2018happy\u2019. Similar comparisons can be made by contrasting other regions with high average scores (e.g. North America, Australia and New Zealand) against those with low average scores (e.g. South Asia).</p>\n\n\n\n<p>Another important point to notice is that the distribution of self-reported life satisfaction in Latin America is high across the board\u2014it is consistently to the right of other regions with roughly comparable income levels, such as Central and Eastern Europe.</p>\n\n\n\n<p>This is part of a broader pattern: Latin American countries tend to have a higher subjective well-being than other countries with comparable levels of economic development. As we will see in the section on <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#the-relationship-between-culture-and-life-satisfaction\">social environment</a>, culture and history matter for self-reported life satisfaction.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/The-distribution-of-life-satisfaction.png\" alt=\"Distribution of self-reported life satisfaction by world region\"/></figure>\n\n\n\n<p>If you are interested in data on country-level distributions of scores, the <a href=\"http://www.pewglobal.org/question-search/?qid=365&cntIDs=&stdIDs=\">Pew Global Attitudes Survey</a> provides such figures for more than 40 countries.</p>\n\n\n\n<h2>(Mis)perceptions about others’ happiness</h2>\n\n\n\n<p>We tend to underestimate the average happiness of people around us. The visualization shown demonstrates this for countries around the world, using data from Ipsos’ <a rel=\"noopener noreferrer\" href=\"http://perils.ipsos.com/\" target=\"_blank\">Perils of Perception</a>\u2014a cross-country survey asking people to guess what others in their country have answered to the happiness question in the World Value Survey.</p>\n\n\n\n<p>The horizontal axis in this chart shows the actual share of people who said they are ‘Very Happy’ or ‘Rather Happy’ in the World Value Survey; the vertical axis shows the average <em>guess</em> of the same number (i.e. the average guess that respondents made of the share of people reporting to be ‘Very Happy’ or ‘Rather Happy’ in their country).</p>\n\n\n\n<p>If respondents would have guessed the correct share, all observations would fall on the red 45-degree line. But as we can see, all countries are far below the 45-degree line. In other words, people in every country underestimated the self-reported happiness of others. The most extreme deviations are in Asia\u2014South Koreans think that 24% of people report being happy, when in reality 90% do.</p>\n\n\n\n<p>The highest guesses in this sample (Canada and Norway) are 60%\u2014this is lower than the lowest actual value of self-reported happiness in any country in the sample (corresponding to Hungary at 69%).</p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others.png\"><img loading=\"lazy\" width=\"550\" height=\"550\" src=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others-550x550.png\" alt=\"\" class=\"wp-image-11310\" srcset=\"https://owid.cloud/app/uploads/2017/04/Happiness-of-others-550x550.png 550w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-150x150.png 150w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-400x400.png 400w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-768x768.png 768w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-32x32.png 32w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-50x50.png 50w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-64x64.png 64w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-96x96.png 96w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-128x128.png 128w\" sizes=\"(max-width: 550px) 100vw, 550px\" /></a></figure></div>\n\n\n\n<p>Why do people get their guesses so wrong? It’s not as simple as brushing aside these numbers by saying they reflect differences in ‘actual’ vs. reported happiness.</p>\n\n\n\n<p>One possible explanation is that people tend to misreport their own happiness, therefore the average guesses might be a correct indicator of true life satisfaction (and an incorrect indicator of <em>reported</em> life satisfaction). However, for this to be true, people would have to commonly misreport their own happiness while assuming that others do <em>not</em> misreport theirs.</p>\n\n\n\n<p>And people are not bad at judging the well-being of other people who they know: There is substantial evidence showing that <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#can-happiness-really-be-measured\">ratings of one’s happiness made by friends correlate with one’s happiness</a>, and that <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#how-much-does-language-matter-for-cross-country-comparisons-of-happiness\">people are generally good at evaluating emotions from simply watching facial expressions</a>.</p>\n\n\n\n<p>An alternative explanation is that this mismatch is grounded in the well-established fact that people tend to be positive about themselves, but negative about other people they don’t know.It has been observed in other contexts that people can be optimistic about their own future, while at the same time being deeply pessimistic about the future of their nation or the world. We discuss this phenomenon in more detail in our entry on <a href=\"https://ourworldindata.org/optimism-pessimism/\">optimism and pessimism</a>, specifically in a section dedicated to <a href=\"https://ourworldindata.org/optimism-pessimism/#individual-optimism-and-social-pessimism\">individual optimism and social pessimism</a>.</p>\n\n\n\n<h2>Differences in happiness within countries</h2>\n\n\n\n<h3>East and West Germany</h3>\n\n\n\n<p>In global surveys of happiness and life satisfaction, <a rel=\"noopener noreferrer\" href=\"https://ourworldindata.org/grapher/happiness-cantril-ladder\" target=\"_blank\">Germany usually ranks high</a>. However, these national averages mask large inequalities.

They note that two-thirds of the black-white happiness gap has been eroded (although today white Americans remain happier on average, even after controlling for differences in education and income), and the gender happiness gap has disappeared entirely (women used to be slightly happier than men, but they are becoming less happy, and today there is no statistical difference once we control for other characteristics).{ref}These results have been discussed in various blogs. Freakonomics provides a quick and interesting overview of the debate, specifically with regard to <a rel=\"noreferrer noopener\" href=\"http://freakonomics.com/2007/10/01/why-are-women-so-unhappy/\" target=\"_blank\">gender gaps</a>.{/ref}</p>\n\n\n\n<p>The results from Stevenson and Wolfers are consistent with other studies looking at changes of happiness inequality (or life satisfaction inequality) over time. In particular, researchers have noted that there is a correlation between economic growth and reductions in happiness inequality\u2014even when <a rel=\"noopener noreferrer\" href=\"https://ourworldindata.org/income-inequality/\" target=\"_blank\">income inequality</a> is increasing at the same time. The visualization here uses data from Clark, Fleche and Senik (2015){ref}Clark, Andrew E., Sarah Fl\u00e8che, and Claudia Senik. \u201cEconomic growth evens out happiness: Evidence from six surveys.\u201d Review of Income and Wealth (2015).

This can still be consistent with growing income inequality, since public goods such as <a href=\"https://ourworldindata.org/health-meta/\">better health</a> affect incomes and well-being differently.</p>\n\n\n\n<p>Another possibility is that economic growth in rich countries has translated into a more diverse society in terms of cultural expressions (e.g. through the emergence of alternative lifestyles), which has allowed people to converge in happiness even if they diverge in incomes, tastes and consumption. Steven Quartz and Annette Asp explain this hypothesis in a <a href=\"https://www.nytimes.com/2015/04/12/opinion/sunday/unequal-yet-happy.html?smid=nytcore-ipad-share&smprod=nytcore-ipad&_r=0\" target=\"_blank\" rel=\"noopener noreferrer\">New York Times article</a>, discussing evidence from experimental psychology.</p>\n\n\n\n<h2>The link between happiness and income</h2>\n\n\n\n<h3>The link across countries</h3>\n\n\n\n<h4>Higher national incomes go together with higher average life satisfaction</h4>\n\n\n\n<p>If we compare life satisfaction reports from around the world at any given point in time, we immediately see that countries with higher average national incomes tend to have higher average life satisfaction scores. In other words: People in richer countries tend to report higher life satisfaction than people in poorer countries. The scatter plot here shows this.</p>\n\n\n\n<p>Each dot in the visualization represents one country. The vertical position of the dots shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction); while the horizontal position shows GDP per capita based on purchasing power parity (i.e. GDP per head after adjusting for inflation and cross-country price differences).</p>\n\n\n\n<p>This correlation holds even if we control for other factors: Richer countries tend to have higher average self-reported life satisfaction than poorer countries that are comparable in terms of demographics and other measurable characteristics. You can read more about this in the <a href=\"http://worldhappiness.report/\">World Happiness Report 2017</a>, specifically the discussion in Chapter 2.</p>\n\n\n\n<p>As we show below, income and happiness also tend to go together <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#higher-personal-incomes-go-together-with-higher-self-reported-life-satisfaction\">within countries</a> and <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#economic-growth-and-happiness\">across time</a>.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/gdp-vs-happiness\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h3>The link within countries</h3>\n\n\n\n<h4>Higher personal incomes go together with higher self-reported life satisfaction</h4>\n\n\n\n<p>Above we point out that richer countries tend to be happier than poorer countries. Here we show that the same tends to be true within countries: richer people within a country tend to be happier than poorer people in the same country. The visualisations here show us this this by looking at happiness by income quintiles.</p>\n\n\n\n<p>Firstly we show each country in individual panels: within each panel is a connected scatter plot for a specific country. This means that for each country, we observe a line joining five points: each point marks the average income within an income quintile (horizontal axis) against the average self-reported life satisfaction of people at that income quintile (vertical axis).</p>\n\n\n\n<p>What does this visualization tell us? We see that in all cases lines are upward sloping: people in higher income quintiles tend to have higher average life satisfaction. Yet in some countries the lines are steep and linear (e.g. in Costa Rica richer people are happier than poorer people across the whole income distribution); while in some countries the lines are less steep and non-linear (e.g. the richest group of people in the Dominican Republic is as happy as the second-richest group).</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-by-Income-Quintiles-Small-Multiples.png\" alt=\"Self-reported life-satisfaction across the income distribution\"/></figure>\n\n\n\n<p>In a second visualization we present the same data, but instead of plotting each country separately, showing all countries in one grid.</p>\n\n\n\n<p>The resulting connected scatter plot may be messy, resembling a \u2018spaghetti\u2019 chart, but it is helpful to confirm the overall pattern: despite kinks here and there, lines are by and large upward sloping.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-across-income-distribution.png\" alt=\"Self-reported life satisfactino across the income distribution, country by country\"/></figure>\n\n\n\n<h3>Looking across and within countries</h3>\n\n\n\n<h4>A snapshot of the correlation between income and happiness\u2014between and within countries</h4>\n\n\n\n<p>Do income and happiness tend to go together? The visualization here shows that the answer to this question is yes, both within and across countries.</p>\n\n\n\n<p>It may take a minute to wrap your head around this visualization, but once you do, you can see that it handily condenses the key information from the previous three charts into one.</p>\n\n\n\n<p>To show the income-happiness correlation across countries, the chart plots the relationship between self-reported life satisfaction on the vertical axis and GDP per capita on the horizontal axis. Each country is an arrow on the grid, and the location of the arrow tells us the corresponding combination of average income and average happiness.</p>\n\n\n\n<p>To show the income-happiness correlation <em>within</em> countries, each arrow has a slope corresponding to the correlation between household incomes and self-reported life satisfaction within that country. In other words: the slope of the arrow shows how strong the relationship between income and life satisfaction is within that country. (<a href=\"https://ourworldindata.org/app/uploads/2013/05/South-Africa-inequality-of-income-and-happiness-as-example.png\">This chart</a> gives you a visual example of how the arrows were constructed for each country). {ref}To be precise, the gradients correspond, country by country, to the regression coefficients between income quintiles and the related average life satisfaction reported by people within each income quintile.{/ref}</p>\n\n\n\n<p>If an arrow points northeast, that means richer people tend to report higher life satisfaction than poorer people in the same country. If an arrow is flat (i.e. points east), that means rich people are on average just as happy as poorer people in the same country.</p>\n\n\n\n<p>As we can see, there is a very clear pattern: richer countries tend to be happier than poorer countries (observations are lined up around an upward-sloping trend), and richer people within countries tend to be happier than poorer people in the same countries (arrows are consistently pointing northeast).</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/GDP-vs-Happiness-and-gradient-within-countries.png\" alt=\"People in richer countries tend to be happier and within all countries richer people tend to be happier\"/></figure>\n\n\n\n<p>It\u2019s important to note that the horizontal axis is measured in a logarithmic scale. The cross-country relationship we would observe in a linear scale would be different, since at high national income levels, slightly higher national incomes are associated with a smaller increase in average happiness than at low levels of national incomes. In other words, the cross-country relationship between income and happiness is not linear on income (it is \u2018log-linear\u2019). We use the logarithmic scale to highlight two key facts: (i) at no point in the global income distribution is the relationship flat; and (ii) a doubling of the average income is associated with roughly the same increase in the reported life-satisfaction, irrespective of the position in the global distribution.</p>\n\n\n\n<p>These findings have been explored in more detail in a number of recent academic studies. Importantly, the much-cited paper by Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87.

Here we want to show that, while less strong, there is also a correlation between income and happiness across time. Or, put differently, as countries get richer, the population tends to report higher average life satisfaction.</p>\n\n\n\n<p>The chart shown here uses data from the World Value Survey to plot the evolution of national average incomes and national average happiness over time. To be specific, this chart shows the share of people who say they are \u2018very happy\u2019 or \u2018rather happy\u2019 in the World Value Survey (vertical axis), against GDP per head (horizontal axis). Each country is drawn as a line joining first and last available observations across all survey waves.{ref}The dataset includes observations for Egypt. However, we have excluded these observations from our analysis. This is because the survey for Egypt in the wave labeled 2014 is from 2012, which was a year characterized by extreme political instability in that country.{/ref}</p>\n\n\n\n<p>As we can see, countries that experience economic growth also tend to experience happiness growth across waves in the World Value Survey. And this is a correlation that holds after controlling for other factors that also change over time (in <a href=\"https://ourworldindata.org/app/uploads/2017/04/Stevenson-Wolfers-2008-%E2%80%93-Happiness-and-Growth-744x550.png\" target=\"_blank\" rel=\"noopener noreferrer\">this chart</a> from Stevenson and Wolfers (2008) you can see how changes in GDP per capita compare to changes in life satisfaction after accounting for changes in demographic composition and other variables).</p>\n\n\n\n<p>An important point to note here is that economic growth and happiness growth tend to go together <em>on average</em>. Some countries in some periods experience economic growth without increasing happiness. The experience of the US in recent decades is a case in point. These instances may seem paradoxical given the evidence\u2014we explore this question in the following section.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"3000\" height=\"2204\" src=\"https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time.png\" alt=\"\" class=\"wp-image-43177\" srcset=\"https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time.png 3000w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-400x294.png 400w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-749x550.png 749w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-150x110.png 150w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-768x564.png 768w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-1536x1128.png 1536w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-2048x1505.png 2048w\" sizes=\"(max-width: 3000px) 100vw, 3000px\" /></figure>\n\n\n\n<h3>The Easterlin Paradox</h3>\n\n\n\n<p>The observation that economic growth does not always go together with increasing life satisfaction was first made by Richard Easterlin in the 1970s. Since then, there has been much discussion over what came to be known as the \u2018Easterlin Paradox\u2019.</p>\n\n\n\n<p>At the heart of the paradox was the fact that richer countries tend to have higher self-reported happiness, yet in some countries for which repeated surveys were available over the course of the 1970s, happiness was not increasing with rising national incomes. This combination of empirical findings was paradoxical because the cross-country evidence (countries with higher incomes tended to have higher self-reported happiness) did not, in some cases, fit the evidence over time (countries seemed not to get happier as national incomes increased).</p>\n\n\n\n<p>Notably, Easterlin and other researchers relied on data from the US and Japan to support this seemingly perplexing observation. If we look closely at the data underpinning the trends in these two countries, however, these cases are not in fact paradoxical.</p>\n\n\n\n<p>Let us begin with the case of Japan. There, the earliest available data on self-reported life satisfaction came from the so-called \u2018Life in Nation surveys\u2019, which date back to 1958. At first glance, this source suggests that mean life satisfaction remained flat over a period of spectacular economic growth (see for example <a href=\"http://ourworldindata.org/app/uploads/2013/05/mean-subjective-well-being-japan-1958-1987-easterlin-in-land-michalos-and-sirgy-ed-2011.png\">this chart</a> from Easterlin and Angelescu 2011).{ref}R.A.

Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online <a href=\"https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF\">here</a>. {/ref} show that the life satisfaction questions in the \u2018Life in Nation surveys\u2019 changed over time, making it difficult\u2014if not impossible\u2014to track changes in happiness over the full period. The visualization here splits the life satisfaction data from the surveys into sub-periods where the questions remained constant. As we can see, the data is not supportive of a paradox: the correlation between GDP and happiness growth in Japan is positive within comparable survey periods. The reason for the alleged paradox is in fact mismeasurement of how happiness changed over time.</p>\n\n\n\n<p>In the US, the explanation is different, but can once again be traced to the underlying data. Specifically, if we look more closely at economic growth in the US over the recent decades, one fact looms large: growth has not benefitted the majority of people. Income inequality in the US is exceptionally high and has been on the rise in the last four decades, with incomes for the median household growing much more slowly than incomes for the top 10%. As a result, trends in aggregate life satisfaction should not be seen as paradoxical: the income and standard of living of the typical US citizen has not grown much in the last couple of decades.

In this visualization, we provide evidence of the cross-country relationship.</p>\n\n\n\n<p>Each dot in the scatterplot represents one country. The vertical position of the dots shows national life expectancy at birth, and the horizontal position shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction).</p>\n\n\n\n<p>As we can see, there is a strong positive correlation: countries where people tend to live longer are also countries where people tend to say more often that they are satisfied with their lives. A similar relationship holds for other health outcomes (e.g. <a href=\"https://ourworldindata.org/grapher/life-satisfaction-vs-child-mortality\">life satisfaction tends to be higher in countries with lower child mortality</a>).</p>\n\n\n\n<p>The relationship plotted in the chart clearly reflects more than just the link between health and happiness, since countries with high life expectancy also tend to be countries with many other distinct characteristics. However, the positive correlation between life expectancy and life satisfaction remains after controlling for observable country characteristics, such as incomes and social protection. You can read more about this in the <a href=\"http://worldhappiness.report/\">World Happiness Report 2017</a>, specifically the discussion in Chapter 2.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/life-satisfaction-vs-life-expectancy\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h3>Mental health and happiness</h3>\n\n\n\n<p>When trying to discern a relationship between <a href=\"https://owid.cloud/mental-health\">mental health</a> and happiness, it is important to distinguish between macro and micro-level correlations. When we look at macro-level, <a rel=\"\u201cnoopener\u201d noopener noreferrer\" href=\"https://ourworldindata.org/grapher/depression-vs-self-reported-life-satisfaction\" target=\"_blank\">cross-country trends</a> in the prevalence of mental health disorders such as depression versus self-reported life satisfaction there is no clear relationship: it does not appear that countries with higher depression rates have lower self-reported happiness.</p>\n\n\n\n<p>However, when we look at micro-level, within-country correlations the data tells a different story. In this visualization, we provide evidence of the relationship between health and subjective well-being within countries\u2014specifically; we focus here on mental health and self-reported life satisfaction.</p>\n\n\n\n<p>Each bar in the visualization measures the extent to which mental illness (depression and anxiety) is associated with self-reported life satisfaction, once we control for physical illness and other factors such as income and education. In other words, the bars show a \u2018conditional correlation\u2019\u2014the strength of the link between mental illness and happiness after accounting for other factors.</p>\n\n\n\n<p>The negative values show that people who have been diagnosed with depression or anxiety tend to be more likely to have lower self-reported life satisfaction.</p>\n\n\n\n<p>The size of the coefficients, particularly in the US, and Australia, tell us that the relationship we observe is very strong. For context, in the UK, the US and Australia the magnitude of the correlation between mental illness and life satisfaction is <a href=\"https://ourworldindata.org/grapher/correlation-income-and-life-satisfaction\">higher than the magnitude for the correlation between income and life satisfaction</a>.</p>\n\n\n\n<p>Clearly, this correlation is likely the result of a two-way relationship: depressed and anxious people are less likely to be happy, and unhappy people are more likely to be depressed or anxious. Nevertheless, it is still important to bear in mind that anxiety, depression and unhappiness often go together.</p>\n\n\n\n<p>Other studies provide further evidence of not only the negative correlation between depression and life satisfaction (i.e individuals with more severe depression report lower life satisfaction), but also evidence that treatment and improvement in depression are linked to increases in self-reported life satisfaction.{ref}Koivumaa\u2010Honkanen, H., Honkanen, R., Antikainen, R., Hintikka, J., Laukkanen, E., Honkalampi, K., & Viinam\u00e4ki, H.

(2008){ref}Clark, A. E., Diener, E., Georgellis, Y., & Lucas, R. E. (2008). Lags and leads in life satisfaction: A test of the baseline hypothesis. The Economic Journal, 118(529).{/ref} use data from the German Socio-Economic Panel to identify groups of people experiencing significant life and labour market events, and trace how these events affect the evolution of their life satisfaction. The visualization here shows an overview of their main findings. In each individual chart, the red lines mark the estimated effect of a different event at a given point in time (with \u2018whiskers\u2019 marking the range of confidence of each estimate).</p>\n\n\n\n<p>In all cases the results are split by gender, and time is labeled so that 0 marks the point when the corresponding event took place (with negative and positive values denoting years before and after the event). All estimates control for individual characteristics, so the figures show the effect of the event after controlling for other factors (e.g. income, etc.).</p>\n\n\n\n<p>The first point to note is that most events denote the evolution of a latent situation: People grow unhappy in the period building up to a divorce, while they grow happy in the period building up to a marriage.</p>\n\n\n\n<p>The second point is that single life events do tend to affect happiness in the short run, but people often adapt to changes. Of course, there are clear differences in the extent to which people adapt. In the case of divorce, life satisfaction first drops, then goes up and stays high. For unemployment, there is a negative shock both in the short and long-run, notably among men. And for marriage, life satisfaction builds up before, and fades out after the wedding.</p>\n\n\n\n<p>In general, the evidence suggests that adaptation is an important feature of well-being. Many common but important life events have a modest long-term impact on self-reported happiness. Yet adaptation to some events, such as long-term unemployment, is neither perfect nor immediate.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Life-events-on-happiness.png\" alt=\"The effect of life events on life satisfaction\"/></figure>\n\n\n\n<h3>Does disability correlate with life satisfaction?</h3>\n\n\n\n<p>A number of papers have noted that long-term paraplegics do not report themselves as particularly unhappy, when compared to non-paraplegics (see for example the much-cited paper by Brickman, Coates, and Janoff-Bulman, 1978).{ref} Brickman, P., Coates, D., & Janoff-Bulman, R. (1978). Lottery winners and accident victims: Is happiness relative?. Journal of personality and social psychology, 36(8), 917. Chicago.

It is, for example, considered in courts of law with respect to the compensation for disability.</p>\n\n\n\n<p>However, comparing differences in self-reported life satisfaction among people with different disability statuses is not an ideal source of evidence regarding the effect of tragedy on happiness. Non-paraplegics are potentially different to paraplegics in ways that are hard to measure. A better source of evidence are longitudinal surveys where people are tracked over time.</p>\n\n\n\n<p>Oswald and Powdthavee (2008){ref}Oswald, A. J., & Powdthavee, N. (2008). Does happiness adapt? A longitudinal study of disability with implications for economists and judges. Journal of public economics, 92(5), 1061-1077.{/ref} use data from a longitudinal survey in the UK to explore whether accidents leading to disability imply long-term shocks to life satisfaction.</p>\n\n\n\n<p>The chart here, from Oswald and Powdthavee, shows the average reported life satisfaction of a group of people who became seriously disabled (at time T) and remained seriously disabled in the two following years (T+1 and T+2). Here, \u2018seriously disabled\u2019 means that disability prevented them from being able to do day-to-day activities.</p>\n\n\n\n<p>As we can see\u2014and as the authors show more precisely through econometric techniques\u2014those entering disability suffer a sudden drop in life satisfaction, and recover only partially. This supports the idea that while adaptation plays a role for common life events, the notion of life satisfaction is indeed sensitive to tragic events.</p>\n\n\n\n<h6><a id=\"Life_satisfaction_of_those_entering_serious_disability_BHPS_19962002__Oswald_and_Powdthavee_2006_280\"></a>Life satisfaction of those entering serious disability, BHPS 1996-2002 \u2013 Oswald and Powdthavee (2006)</h6>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Disability-and-happiness-Oswald-and-Powdthavee-2006.png\" alt=\"Life satisfaction of those entering serious disability\"/></figure>\n\n\n\n<h2>Life satisfaction and society</h2>\n\n\n\n<h3>Culture and life satisfaction</h3>\n\n\n\n<p>Comparisons of happiness among countries suggest that culture and history shared by people in a given society matter for self-reported life satisfaction. For example, as the chart here shows, culturally and historically similar Latin American countries have a higher subjective well-being than other countries with comparable levels of economic development. (This chart plots self-reported life satisfaction as measured in the 10-point Cantril ladder in the vertical axis, against GDP per capita in the horizontal axis).</p>\n\n\n\n<p>Latin America is not a special case in this respect. Ex-communist countries, for example, tend to have lower subjective well-being than other countries with comparable characteristics and levels of economic development.</p>\n\n\n\n<p>Academic studies in positive psychology discuss other patterns. Diener and Suh (2002) write: \u201cIn recent years cultural differences in subjective well-being have been explored, with a realization that there are profound differences in what makes people happy. Self-esteem, for example, is less strongly associated with life satisfaction, and extraversion is less strongly associated with pleasant affect in collectivist cultures than in individualist cultures\u201d.{ref}Diener, E., Oishi, S., & Lucas, R. E. (2009). Subjective well-being: The science of happiness and life satisfaction. Oxford handbook of positive psychology, 2, 187-194.{/ref}</p>\n\n\n\n<p>To our knowledge, there are no rigorous studies exploring the causal mechanisms linking culture and happiness. However, it seems natural to expect that cultural factors shape the way people collectively understand happiness and the meaning of life.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2013/05/continent-version-GDP-pc-vs-Happiness-By-culture.png\" alt=\"Self-reported life satisfaction vs GDP per capita, in 2015\"/></figure>\n\n\n\n<h3>Sense of freedom and life satisfaction</h3>\n\n\n\n<p>A particular channel through which social environment may affect happiness is freedom: the society we live in may crucially affect the availability of options that we have to shape our own life.</p>\n\n\n\n<p>This visualization shows the relationship between self-reported sense of freedom and self-reported life satisfaction using data from the <a href=\"http://www.gallup.com/services/170945/world-poll.aspx\">Gallup World Poll</a>. The variable measuring life satisfaction corresponds to country-level averages of survey responses to the Cantril Ladder question (a 0-10 scale, where 10 is the highest level of life satisfaction); while the variable measuring freedom corresponds to the share of people who agree with the statement \u201cIn this country, I am satisfied with my freedom to choose what I do with my life\u201d.{ref}To be precise, the Gallup World Poll asks: \u201cIn this country, are you satisfied or dissatisfied with your freedom to choose what you do with your life?\u201d{/ref}</p>\n\n\n\n<p>As we can see, there is a clear positive relationship: countries where people feel free to choose and control their lives tend to be countries where people are happier. As Inglehart et al. (2008){ref}Inglehart, R., Foa, R., Peterson, C., & Welzel, C. (2008). Development, freedom, and rising happiness: A global perspective (1981\u20132007). Perspectives on psychological science, 3(4), 264-285.{/ref} show, this positive relationship holds even after we control for other factors, such as incomes and strength of religiosity.</p>\n\n\n\n<p>Interestingly, this chart also shows that while there are some countries where the perceived sense of freedom is high but average life satisfaction is low (e.g. Rwanda); there are no countries where the perceived sense of freedom is low but average life satisfaction is high (i.e. there are no countries in the top left area of the chart).</p>\n\n\n\n<p>To our knowledge there are no rigorous studies exploring the causal mechanisms linking freedom and happiness. However, it seems natural to expect that self-determination and absence of coercion are important components of what people consider a happy and meaningful life.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2013/05/Happiness-vs-Freedom-in-Your-Life.png\" alt=\"Perception of freedom vs self-reported life satisfaction, 2016\"/></figure>\n\n\n\n<h3>The link between media and gloominess</h3>\n\n\n\n<p>A number of studies have found that there is a link between emotional exposure to negative content in news and changes in mood.</p>\n\n\n\n<p>Johnston and Davey (1997),{ref} Johnston, W. M., & Davey, G. C. (1997). The psychological impact of negative TV news bulletins: The catastrophizing of personal worries. British Journal of Psychology, 88(1), 85-91.{/ref} for example, conducted an experiment in which they edited short TV news to display positive, neutral or negative material, and then showed them to three different groups of people. The authors found that people who watched the \u2018negative\u2019 clip were more likely to report a sad mood.</p>\n\n\n\n<p>This link between emotional content in news and changes in mood is all the more important if we consider that media gatekeepers tend to prefer negative to positive coverage of newsworthy facts (see, for example, Combs and Slovic 1979{ref} Combs, B., & Slovic, P. (1979). Newspaper coverage of causes of death. Journalism Quarterly, 56(4), 837-849.{/ref}).</p>\n\n\n\n<p>Of course, mood is not the same as life satisfaction. Yet, as we discuss below in the <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#data-quality-and-measurement\">section on measurement and data quality</a>, surveys measuring happiness often do capture emotional aspects of well-being. And in any case, people\u2019s perceptions of what it means to lead a meaningful life are heavily influenced by their expectations of what is possible and likely to occur with their lives; and this has also been shown to depend on media exposure.{ref}Riddle (2010), for example, found that people watching more vivid violent media gave higher estimates of the prevalence of crime in the real world. (Riddle, 2010, \u201cAlways on my mind: Exploring how frequent, recent, and vivid television portrayals are used in the formation of social reality judgments.\u201d Media Psychology.) {/ref}</p>\n\n\n\n<h2>Data Quality and Measurement</h2>\n\n\n\n<h3>Can \u2018happiness\u2019 really be measured?</h3>\n\n\n\n<p>The most natural way to attempt to measure subjective well-being is to ask people what they think and feel. Indeed, this is the most common approach.</p>\n\n\n\n<p>In practice, social scientists tend to rely on questions inquiring directly about happiness, or on questions inquiring about life satisfaction. The former tend to measure the experiential or emotional aspects of well-being (e.g. \u201cI feel very happy\u201d), while the latter tend to measure the evaluative or cognitive aspects of well-being (e.g. \u201cI think I lead a very positive life\u201d).</p>\n\n\n\n<p>Self-reports about happiness and life satisfaction are known to correlate with things that people typically associate with contentment, such as cheerfulness and smiling. (In <a href=\"https://ourworldindata.org/app/uploads/2017/04/Life-Satisfaction-vs-Laugh-Gallup.png\">this scatter plot</a> you can see that countries where people have higher self-reported life satisfaction are also countries where people tend to smile more).</p>\n\n\n\n<p>Experimental psychologists have also shown that self reports of well-being from surveys turn out to correlate with activity in the parts of the brain associated with pleasure and satisfaction. And various surveys have confirmed that people who say they are happy also tend to sleep better and express positive emotions verbally more frequently.</p>\n\n\n\n<p>The following table, adapted from Kahneman and Krueger (2006){ref}Kahneman, D., & Krueger, A.

However, it is important to bear in mind that \u201clife satisfaction\u201d and \u201chappiness\u201d are not really synonyms. And this is of course reflected in the data, since self-reported measures of these two variables come from asking different kinds of questions.</p>\n\n\n\n<p>The World Value Survey asks directly about happiness: <em>\u201cTaking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy, (iv) Not at all happy, (v) Don\u2019t know.\u201d</em></p>\n\n\n\n<p>The Gallup World Poll, on the other hand, uses the Cantril Ladder question and asks respondents to evaluate their life: <em>\u201cPlease imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?\u201d</em></p>\n\n\n\n<p>As the following scatter plot shows, these two measures are clearly closely related (countries that score high in one measure also tend to score high in the other), yet they are not identical (there is substantial dispersion, with many countries sharing the same score in one variable but diverging in the other).</p>\n\n\n\n<p>The differences in responses to questions inquiring about life satisfaction and happiness are consistent with the idea that subjective well-being has two sides: an experiential or emotional side, and an evaluative or cognitive side. Of course, the limits between emotional and cognitive aspects of well-being are blurred in our minds; so in practice both kinds of questions measure both aspects to some degree. Indeed, social scientists often construct \u2018subjective well-being indexes\u2019 where they simply average out results from various types of questions.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/Happiness-WVS-vs-Gallup\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h3>Are happiness averages really meaningful?</h3>\n\n\n\n<p>The most common way to analyze data on happiness consists in taking averages across groups of people. Indeed, cross-country comparisons of self-reported life satisfaction, such as those presented in \u2018happiness rankings\u2019, rely on national averages of reports on a scale from 0 to 10 (the Cantril Ladder).</p>\n\n\n\n<p>Is it reasonable to take averages of life satisfaction scores? Or, in more technical terms: are self reports of Cantril scores really a cardinal measure of well-being?</p>\n\n\n\n<p>The evidence tells us that survey-based reports on the Cantril Ladder do allow cardinal measurement reasonably well\u2014respondents have been found to translate verbal labels, such as \u2018very good\u2019 and \u2018very bad\u2019, into roughly the same numerical values.{ref}Ferrer\u2010i\u2010Carbonell, A., & Frijters, P. (2004). How important is methodology for the estimates of the determinants of happiness?. The Economic Journal, 114(497), 641-659.{/ref} {ref}Van Praag, B.M.S. (1991). \u2018Ordinal and cardinal utility: an integration of the two dimensions of the welfare concept\u2019, Journal of Econometrics, vol. 50, pp. 69\u201389.{/ref}</p>\n\n\n\n<p>But as with any other aggregate indicator of social progress, averages need to be interpreted carefully, even if they make sense arithmetically. For example, if we look at happiness by age in a given country, we may see that older people do not appear to be happier than younger people. Yet this may be because the average-by-age figure from the snapshot confounds two factors: the age effect (people from the same cohort do get happier as they grow older, across all cohorts) and the cohort effect (across all ages, earlier generations are less happy than more recent generations). If the cohort effect is very strong, the snapshot can even give a picture that suggests people become <em>less</em> happy as they grow older, even though the exact opposite is actually true within all generations.</p>\n\n\n\n<p>This example is in fact taken from the real world: using data from the US, Sutin et al. (2013){ref}Sutin, A. R., Terracciano, A., Milaneschi, Y., An, Y., Ferrucci, L., & Zonderman, A. B. (2013). The effect of birth cohort on well-being The legacy of economic hard times. Psychological science, 0956797612459658.{/ref} showed that self-reported feelings of well-being tend to increase with age across generations, but overall levels of well-being depend on when people were born.</p>\n\n\n\n<h4>How much does language matter for cross-country comparisons of happiness?</h4>\n\n\n\n<p>Linguistic differences are often seen as a major obstacle for making cross-country comparisons of happiness. However, there is evidence suggesting that comparability issues, at least in respect to language, are less problematic than many people think.</p>\n\n\n\n<p>Studies have shown, for example, that in interviews in which respondents are shown pictures or videos of other individuals, respondents can broadly identify whether the individual shown to them was happy or sad; and this is also true when respondents were asked to predict the evaluations of individuals from other cultural communities. (For evidence of this see Sandvik et al., 1993; Diener and Lucas, 1999).{ref}Sandvik, E., Diener, E. and Seidlitz, L. (1993). \u2018Subjective well-being: the convergence and stability of self and non self report measures\u2019, Journal of Personality, vol. 61, pp. 317\u201342. Diener, E. and Lucas, R.E. (1999). \u2018Personality and subjective well-being\u2019, in Kahneman et al. (1999) chapter 11.{/ref}</p>\n\n\n\n<p>Studies have also shown that \u2018indigenous emotions\u2019 across cultures (i.e. feelings that are unique in that they do not have equivalents in the English language) are not experienced any more frequently or differently than common translated emotions. (See Scollon et al. 2005).{ref}Scollon, C. N., Diener, E., Oishi, S., & Biswas-Diener, R. (2004). Emotions across cultures and methods. Journal of cross-cultural psychology, 35(3), 304-326.{/ref}</p>\n\n\n\n<p>The conclusion, therefore, seems to be that there is some basic understanding among humans about what it means to be \u2018happy\u2019. Survey-based measures of self-reported life satisfaction are informative about cross-country differences, even if these comparisons are obviously noisy.</p>\n\n\n\n<h2>Data Sources</h2>\n\n\n\n<h4>Cross-country estimates</h4>\n\n\n\n<h4><a id=\"World_Happiness_Report_379\"></a>World Happiness Report</h4>\n\n\n\n<ul><li><strong>Data:</strong> Country averages of self-reported life satisfaction (Question: Cantril Ladder).</li><li><strong>Underlying source:</strong> Gallup World Poll</li><li><strong>Time span:</strong> 2005-2022</li><li><strong>Available at:</strong> <a href=\"http://worldhappiness.report/\">World Happiness Report</a></li></ul>\n\n\n\n<h4><a id=\"European_Commission__Eurobarometer_Interactive_386\"></a>European Commission \u2013 Eurobarometer Interactive</h4>\n\n\n\n<ul><li><strong>Data:</strong> Life satisfaction (Question: <em>\u201cOn the whole are you very satisfied, fairly satisfied, not very satisfied or not at all satisfied with the life you lead ?\u201d</em>)</li><li><strong>Geographical coverage:</strong> EU countries</li><li><strong>Time span:</strong> 1973 – 2015</li><li><strong>Available at:</strong> <a href=\"http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index\">http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index</a></li></ul>\n\n\n\n<hr class=\"wp-block-separator\"/>\n\n\n\n<h4><a id=\"The_World_Value_Survey_WVS_395\"></a>The World Value Survey (WVS)</h4>\n\n\n\n<ul><li><strong>Data:</strong> Happiness and life satisfaction, as well as many other social and cultural characteristics from cross-national time-series surveys.

<div class="blog-info"> <p>First published in 2013; substantive revision May 2017.</p> <p>The <strong>French translation</strong> of this entry is here: <a href="https://ourworldindata.org/bonheur-et-satisfaction/">Bonheur et satisfaction</a></p> </div>   <p>How happy are people today? Were people happier in the past? How satisfied with their lives are people in different societies? And how do our living conditions affect all of this?</p>   <p>These are difficult questions to answer; but they are questions that undoubtedly matter for each of us personally. Indeed, today, life satisfaction and happiness are central research areas in the social sciences, including in ‘mainstream’ economics.</p>   <p>Social scientists often recommend that measures of subjective well-being should augment the usual measures of economic prosperity, such as <a rel="noopener noreferrer" href="https://ourworldindata.org/economic-growth" target="_blank">GDP per capita</a>.{ref}Particularly important was the <a rel="noreferrer noopener" href="https://en.wikipedia.org/wiki/Commission_on_the_Measurement_of_Economic_Performance_and_Social_Progress" target="_blank">Stiglitz-Sen-Fitoussi Commission</a>. It also relates to Bhutan’s famous measurement of Gross National Happiness (GNH) as indicator of progress (Wikipedia <a rel="noreferrer noopener" href="http://en.wikipedia.org/wiki/Gross_national_happiness" target="_blank">here</a>).{/ref} But how can happiness be measured? Are there reliable comparisons of happiness across time and space that can give us clues regarding what makes people declare themselves ‘happy’?</p>   <p>In this entry, we discuss the data and empirical evidence that might answer these questions. Our focus here will be on survey-based measures of self-reported happiness and life satisfaction. Here is a preview of what the data reveals.</p>   <ol><li>Surveys asking people about life satisfaction and happiness do measure subjective well-being with reasonable accuracy.</li><li>Life satisfaction and happiness vary widely both within and among countries. It only takes a glimpse at the data to see that people are distributed along a wide spectrum of happiness levels.</li><li>Richer people tend to say they are happier than poorer people; richer countries tend to have higher average happiness levels; and across time, most countries that have experienced sustained economic growth have seen increasing happiness levels. So the evidence suggests that income and life satisfaction tend to go together (which still doesn’t mean they are one and the same).</li><li>Important life events such as marriage or divorce do affect our happiness, but have surprisingly little long-term impact. The evidence suggests that people tend to adapt to changes.</li></ol>   <h2>Happiness across the world today</h2>   <p>The World Happiness Report is a well-known source of cross-country data and research on self-reported life satisfaction. The map here shows, country by country, the ‘happiness scores’ published this report.</p>   <p>The underlying source of the happiness scores in the World Happiness Report is the <a href="http://www.gallup.com/services/170945/world-poll.aspx" target="_blank" rel="noopener noreferrer">Gallup World Poll</a>—a set of nationally representative surveys undertaken in more than 160 countries in over 140 languages. The main life evaluation question asked in the poll is: “Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?” (Also known as the “Cantril Ladder”.)</p>   <p>The map plots the average answer that survey-respondents provided to this question in different countries. As with the steps of the ladder, values in the map range from 0 to 10.</p>   <p>There are large differences across countries. According to the most recent figures, European countries top the ranking: Finland, Denmark, Iceland, Switzerland and the Netherlands have the highest scores (all with averages above 7). In the same year, the lowest national scores correspond to Afghanistan, Lebanon, Zimbabwe, Rwanda and Botswana (all with average scores below 3.5).</p>   <p>You can click on any country on the map to plot time-series for specific countries.</p>   <p>As we can see, self-reported life satisfaction correlates with other measures of well-being—richer and healthier countries tend to have higher average happiness scores. (More on this in the section <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#correlates-determinants-and-consequences">below</a>.)</p>   <iframe src="https://ourworldindata.org/grapher/happiness-cantril-ladder" width="“300”" height="“150”"></iframe>   <h2>Happiness over time</h2>   <h4>Findings from the World Value Survey</h4>   <p>In addition to the Gallup World Poll (discussed above), the <a href="http://www.worldvaluessurvey.org/WVSDocumentationWV6.jsp">World Value Survey</a> also provides cross-country data on self-reported life satisfaction. These are the longest available time series of cross-country happiness estimates that include non-European nations.</p>   <p>The World Value Survey collects data from a series of representative national surveys covering almost 100 countries, with the earliest estimates dating back to 1981. In these surveys, respondents are asked: “Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy or (iv) Not at all happy”. This visualization plots the share of people answering they are Very happy or Rather happy.</p>   <p>As we can see, in the majority of countries the trend is positive: In 49 of the 69 countries with data from two or more surveys, <a href="https://ourworldindata.org/grapher/share-who-say-happy-wvs-first-to-last">the most recent observation is higher than the earliest</a>. In some cases, the improvement has been very large; in Zimbabwe, for example, the share of people who reported being ‘very happy’ or ‘rather happy’ went from 56.4% in 2004 to 82.1% in 2014.</p>   <iframe src="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy" width="“300”" height="“150”"></iframe>   <h4>Findings from Eurobarometer</h4>   <p>The <a href="http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/General/index">Eurobarometer</a> collects data on life satisfaction as part of their public opinion surveys. For several countries, these surveys have been conducted at least annually for more than 40 years. The visualization here shows the share of people who report being ‘very satisfied’ or ‘fairly satisfied’ with their standards of living, according to this source.</p>   <p>Two points are worth emphasizing. First, estimates of life satisfaction often fluctuate around trends. In France, for example, we can see that the overall trend in the period 1974-2016 is positive; yet there is a pattern of ups and downs. And second, despite temporary fluctuations, decade-long trends have been generally positive for most European countries.</p>   <p>In most cases, the share of people who say they are ‘very satisfied’ or ‘fairly satisfied’ with their life has gone up over the full survey period.{ref}To be precise, in 27 out of 31 countries with data spanning longer than one decade, the estimate for 2016 is higher than the earliest available estimate.{/ref} Yet there are some clear exceptions, of which Greece is the most notable example. Add Greece to the chart and you can see that in 2007, around 67% of the Greeks said they were satisfied with their life; but five years later, after the financial crisis struck, the corresponding figure was down to 32.4%. Despite recent improvements, Greeks today are on average much less satisfied with their lives than before the financial crisis. No other European country in this dataset has gone through a comparable negative shock.</p>   <iframe src="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy-eurobarometer" width="“300”" height="“150”"></iframe>   <h2>The distribution of life satisfaction</h2>   <h4>More than averages—the distribution of life satisfaction scores</h4>   <p>Most of the studies comparing happiness and life satisfaction among countries focus on averages. However, distributional differences are also important.</p>   <p>Life satisfaction is often reported on a scale from 0 to 10, with 10 representing the highest possible level of satisfaction. This is the so-called ‘Cantril Ladder’. This visualization shows how responses are distributed across steps in this ladder. In each case, the height of bars is proportional to the fraction of answers at each score. Each differently-colored distribution refers to a world region; and for each region, we have overlaid the distribution for the entire world as a reference.</p>   <p>These plots show that in sub-Saharan Africa—the region with the lowest average scores–the distributions are consistently to the left of those in Europe. In economics lingo, we observe that the distribution of scores in European countries <em>stochastically dominates</em> the distribution in sub-Saharan Africa.</p>   <p>This means that the share of people who are ‘happy’ is lower in sub-Saharan Africa than in Western Europe, independently of which score in the ladder we use as a threshold to define ‘happy’. Similar comparisons can be made by contrasting other regions with high average scores (e.g. North America, Australia and New Zealand) against those with low average scores (e.g. South Asia).</p>   <p>Another important point to notice is that the distribution of self-reported life satisfaction in Latin America is high across the board—it is consistently to the right of other regions with roughly comparable income levels, such as Central and Eastern Europe.</p>   <p>This is part of a broader pattern: Latin American countries tend to have a higher subjective well-being than other countries with comparable levels of economic development. As we will see in the section on <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#the-relationship-between-culture-and-life-satisfaction">social environment</a>, culture and history matter for self-reported life satisfaction.</p>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2017/04/The-distribution-of-life-satisfaction.png" alt="Distribution of self-reported life satisfaction by world region"/></figure>   <p>If you are interested in data on country-level distributions of scores, the <a href="http://www.pewglobal.org/question-search/?qid=365&cntIDs=&stdIDs=">Pew Global Attitudes Survey</a> provides such figures for more than 40 countries.</p>   <h2>(Mis)perceptions about others' happiness</h2>    <p>We tend to underestimate the average happiness of people around us. The visualization shown demonstrates this for countries around the world, using data from Ipsos' <a rel="noopener noreferrer" href="http://perils.ipsos.com/" target="_blank">Perils of Perception</a>—a cross-country survey asking people to guess what others in their country have answered to the happiness question in the World Value Survey.</p>   <p>The horizontal axis in this chart shows the actual share of people who said they are 'Very Happy' or 'Rather Happy' in the World Value Survey; the vertical axis shows the average <em>guess</em> of the same number (i.e. the average guess that respondents made of the share of people reporting to be 'Very Happy' or 'Rather Happy' in their country).</p>   <p>If respondents would have guessed the correct share, all observations would fall on the red 45-degree line. But as we can see, all countries are far below the 45-degree line. In other words, people in every country underestimated the self-reported happiness of others. The most extreme deviations are in Asia—South Koreans think that 24% of people report being happy, when in reality 90% do.</p>   <p>The highest guesses in this sample (Canada and Norway) are 60%—this is lower than the lowest actual value of self-reported happiness in any country in the sample (corresponding to Hungary at 69%).</p>   <div class="wp-block-image"><figure class="aligncenter"><a href="https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others.png"><img src="https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others-550x550.png" alt="" class="wp-image-11310"/></a></figure></div>   <p>Why do people get their guesses so wrong? It's not as simple as brushing aside these numbers by saying they reflect differences in 'actual' vs. reported happiness.</p>   <p>One possible explanation is that people tend to misreport their own happiness, therefore the average guesses might be a correct indicator of true life satisfaction (and an incorrect indicator of <em>reported</em> life satisfaction). However, for this to be true, people would have to commonly misreport their own happiness while assuming that others do <em>not</em> misreport theirs.</p>   <p>And people are not bad at judging the well-being of other people who they know: There is substantial evidence showing that <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#can-happiness-really-be-measured">ratings of one's happiness made by friends correlate with one's happiness</a>, and that <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#how-much-does-language-matter-for-cross-country-comparisons-of-happiness">people are generally good at evaluating emotions from simply watching facial expressions</a>.</p>   <p>An alternative explanation is that this mismatch is grounded in the well-established fact that people tend to be positive about themselves, but negative about other people they don't know.It has been observed in other contexts that people can be optimistic about their own future, while at the same time being deeply pessimistic about the future of their nation or the world. We discuss this phenomenon in more detail in our entry on <a href="https://ourworldindata.org/optimism-pessimism/">optimism and pessimism</a>, specifically in a section dedicated to <a href="https://ourworldindata.org/optimism-pessimism/#individual-optimism-and-social-pessimism">individual optimism and social pessimism</a>.</p>   <h2>Differences in happiness within countries</h2>   <h3>East and West Germany</h3>    <p>In global surveys of happiness and life satisfaction, <a rel="noopener noreferrer" href="https://ourworldindata.org/grapher/happiness-cantril-ladder" target="_blank">Germany usually ranks high</a>.

They note that two-thirds of the black-white happiness gap has been eroded (although today white Americans remain happier on average, even after controlling for differences in education and income), and the gender happiness gap has disappeared entirely (women used to be slightly happier than men, but they are becoming less happy, and today there is no statistical difference once we control for other characteristics).{ref}These results have been discussed in various blogs.

In particular, researchers have noted that there is a correlation between economic growth and reductions in happiness inequality—even when <a rel="noopener noreferrer" href="https://ourworldindata.org/income-inequality/" target="_blank">income inequality</a> is increasing at the same time.

It plots the evolution of happiness inequality within a selection of rich countries that experienced uninterrupted GDP growth.</p>   <p>In this chart, happiness inequality is measured by the dispersion — specifically the standard deviation — of answers in the World Value Survey. As we can see, there is a broad negative trend. In their paper the authors show that the trend is positive in countries with falling GDP.</p>   <iframe src="https://ourworldindata.org/grapher/evolution-of-happiness-inequality-within-countries-during-periods-of-uninterrupted-economic-growth" width="“300”" height="“150”"></iframe>   <p>Why could it be that happiness inequality falls with rising income inequality?</p>   <p>Clark, Fleche, and Senik argue that part of the reason is that the growth of national income allows for the greater provision of public goods, which in turn tighten the distribution of subjective well-being. This can still be consistent with growing income inequality, since public goods such as <a href="https://ourworldindata.org/health-meta/">better health</a> affect incomes and well-being differently.</p>   <p>Another possibility is that economic growth in rich countries has translated into a more diverse society in terms of cultural expressions (e.g. through the emergence of alternative lifestyles), which has allowed people to converge in happiness even if they diverge in incomes, tastes and consumption. Steven Quartz and Annette Asp explain this hypothesis in a <a href="https://www.nytimes.com/2015/04/12/opinion/sunday/unequal-yet-happy.html?smid=nytcore-ipad-share&smprod=nytcore-ipad&_r=0" target="_blank" rel="noopener noreferrer">New York Times article</a>, discussing evidence from experimental psychology.</p>   <h2>The link between happiness and income</h2>   <h3>The link across countries</h3>   <h4>Higher national incomes go together with higher average life satisfaction</h4>   <p>If we compare life satisfaction reports from around the world at any given point in time, we immediately see that countries with higher average national incomes tend to have higher average life satisfaction scores. In other words: People in richer countries tend to report higher life satisfaction than people in poorer countries. The scatter plot here shows this.</p>   <p>Each dot in the visualization represents one country. The vertical position of the dots shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction); while the horizontal position shows GDP per capita based on purchasing power parity (i.e. GDP per head after adjusting for inflation and cross-country price differences).</p>   <p>This correlation holds even if we control for other factors: Richer countries tend to have higher average self-reported life satisfaction than poorer countries that are comparable in terms of demographics and other measurable characteristics. You can read more about this in the <a href="http://worldhappiness.report/">World Happiness Report 2017</a>, specifically the discussion in Chapter 2.</p>   <p>As we show below, income and happiness also tend to go together <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#higher-personal-incomes-go-together-with-higher-self-reported-life-satisfaction">within countries</a> and <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#economic-growth-and-happiness">across time</a>.</p>   <iframe src="https://ourworldindata.org/grapher/gdp-vs-happiness" width="“300”" height="“150”"></iframe>   <h3>The link within countries</h3>   <h4>Higher personal incomes go together with higher self-reported life satisfaction</h4>   <p>Above we point out that richer countries tend to be happier than poorer countries. Here we show that the same tends to be true within countries: richer people within a country tend to be happier than poorer people in the same country. The visualisations here show us this this by looking at happiness by income quintiles.</p>   <p>Firstly we show each country in individual panels: within each panel is a connected scatter plot for a specific country. This means that for each country, we observe a line joining five points: each point marks the average income within an income quintile (horizontal axis) against the average self-reported life satisfaction of people at that income quintile (vertical axis).</p>   <p>What does this visualization tell us? We see that in all cases lines are upward sloping: people in higher income quintiles tend to have higher average life satisfaction. Yet in some countries the lines are steep and linear (e.g. in Costa Rica richer people are happier than poorer people across the whole income distribution); while in some countries the lines are less steep and non-linear (e.g. the richest group of people in the Dominican Republic is as happy as the second-richest group).</p>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2017/04/Happiness-by-Income-Quintiles-Small-Multiples.png" alt="Self-reported life-satisfaction across the income distribution"/></figure>   <p>In a second visualization we present the same data, but instead of plotting each country separately, showing all countries in one grid.</p>   <p>The resulting connected scatter plot may be messy, resembling a ‘spaghetti’ chart, but it is helpful to confirm the overall pattern: despite kinks here and there, lines are by and large upward sloping.</p>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2017/04/Happiness-across-income-distribution.png" alt="Self-reported life satisfactino across the income distribution, country by country"/></figure>   <h3>Looking across and within countries</h3>   <h4>A snapshot of the correlation between income and happiness—between and within countries</h4>   <p>Do income and happiness tend to go together? The visualization here shows that the answer to this question is yes, both within and across countries.</p>   <p>It may take a minute to wrap your head around this visualization, but once you do, you can see that it handily condenses the key information from the previous three charts into one.</p>   <p>To show the income-happiness correlation across countries, the chart plots the relationship between self-reported life satisfaction on the vertical axis and GDP per capita on the horizontal axis. Each country is an arrow on the grid, and the location of the arrow tells us the corresponding combination of average income and average happiness.</p>   <p>To show the income-happiness correlation <em>within</em> countries, each arrow has a slope corresponding to the correlation between household incomes and self-reported life satisfaction within that country. In other words: the slope of the arrow shows how strong the relationship between income and life satisfaction is within that country. (<a href="https://ourworldindata.org/app/uploads/2013/05/South-Africa-inequality-of-income-and-happiness-as-example.png">This chart</a> gives you a visual example of how the arrows were constructed for each country). {ref}To be precise, the gradients correspond, country by country, to the regression coefficients between income quintiles and the related average life satisfaction reported by people within each income quintile.{/ref}</p>   <p>If an arrow points northeast, that means richer people tend to report higher life satisfaction than poorer people in the same country. If an arrow is flat (i.e. points east), that means rich people are on average just as happy as poorer people in the same country.</p>   <p>As we can see, there is a very clear pattern: richer countries tend to be happier than poorer countries (observations are lined up around an upward-sloping trend), and richer people within countries tend to be happier than poorer people in the same countries (arrows are consistently pointing northeast).</p>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2017/04/GDP-vs-Happiness-and-gradient-within-countries.png" alt="People in richer countries tend to be happier and within all countries richer people tend to be happier"/></figure>   <p>It’s important to note that the horizontal axis is measured in a logarithmic scale. The cross-country relationship we would observe in a linear scale would be different, since at high national income levels, slightly higher national incomes are associated with a smaller increase in average happiness than at low levels of national incomes. In other words, the cross-country relationship between income and happiness is not linear on income (it is ‘log-linear’). We use the logarithmic scale to highlight two key facts: (i) at no point in the global income distribution is the relationship flat; and (ii) a doubling of the average income is associated with roughly the same increase in the reported life-satisfaction, irrespective of the position in the global distribution.</p>   <p>These findings have been explored in more detail in a number of recent academic studies. Importantly, the much-cited paper by Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online <a rel="noreferrer noopener" href="https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF" target="_blank">here</a>. {/ref} shows that these correlations hold even after controlling for various country characteristics such as demographic composition of the population, and are robust to different sources of data and types of subjective well-being measures.</p>   <h3>Economic growth and happiness</h3>   <p>In the charts above we show that there is robust evidence of a strong correlation between income and happiness across and within countries at fixed points in time. Here we want to show that, while less strong, there is also a correlation between income and happiness across time. Or, put differently, as countries get richer, the population tends to report higher average life satisfaction.</p>   <p>The chart shown here uses data from the World Value Survey to plot the evolution of national average incomes and national average happiness over time. To be specific, this chart shows the share of people who say they are ‘very happy’ or ‘rather happy’ in the World Value Survey (vertical axis), against GDP per head (horizontal axis). Each country is drawn as a line joining first and last available observations across all survey waves.{ref}The dataset includes observations for Egypt. However, we have excluded these observations from our analysis. This is because the survey for Egypt in the wave labeled 2014 is from 2012, which was a year characterized by extreme political instability in that country.{/ref}</p>   <p>As we can see, countries that experience economic growth also tend to experience happiness growth across waves in the World Value Survey. And this is a correlation that holds after controlling for other factors that also change over time (in <a href="https://ourworldindata.org/app/uploads/2017/04/Stevenson-Wolfers-2008-%E2%80%93-Happiness-and-Growth-744x550.png" target="_blank" rel="noopener noreferrer">this chart</a> from Stevenson and Wolfers (2008) you can see how changes in GDP per capita compare to changes in life satisfaction after accounting for changes in demographic composition and other variables).</p>   <p>An important point to note here is that economic growth and happiness growth tend to go together <em>on average</em>. Some countries in some periods experience economic growth without increasing happiness. The experience of the US in recent decades is a case in point. These instances may seem paradoxical given the evidence—we explore this question in the following section.</p>   <figure class="wp-block-image size-full"><img src="https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time.png" alt="" class="wp-image-43177"/></figure>   <h3>The Easterlin Paradox</h3>   <p>The observation that economic growth does not always go together with increasing life satisfaction was first made by Richard Easterlin in the 1970s. Since then, there has been much discussion over what came to be known as the ‘Easterlin Paradox’.</p>   <p>At the heart of the paradox was the fact that richer countries tend to have higher self-reported happiness, yet in some countries for which repeated surveys were available over the course of the 1970s, happiness was not increasing with rising national incomes. This combination of empirical findings was paradoxical because the cross-country evidence (countries with higher incomes tended to have higher self-reported happiness) did not, in some cases, fit the evidence over time (countries seemed not to get happier as national incomes increased).</p>   <p>Notably, Easterlin and other researchers relied on data from the US and Japan to support this seemingly perplexing observation. If we look closely at the data underpinning the trends in these two countries, however, these cases are not in fact paradoxical.</p>   <p>Let us begin with the case of Japan. There, the earliest available data on self-reported life satisfaction came from the so-called ‘Life in Nation surveys’, which date back to 1958. At first glance, this source suggests that mean life satisfaction remained flat over a period of spectacular economic growth (see for example <a href="http://ourworldindata.org/app/uploads/2013/05/mean-subjective-well-being-japan-1958-1987-easterlin-in-land-michalos-and-sirgy-ed-2011.png">this chart</a> from Easterlin and Angelescu 2011).{ref}R.A. Easterlin and L. Angelescu – ‘Modern Economic Growth and Quality of Life: Cross-Sectional and Time Series Evidence’ in Land, Michalos, and Sirgy (ed.) (2011) – Handbook of Social Indicators and Quality of Life Research. Springer.{/ref} Digging a bit deeper, however, we find that things are more complex.</p>   <p>Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online <a href="https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF">here</a>. {/ref} show that the life satisfaction questions in the ‘Life in Nation surveys’ changed over time, making it difficult—if not impossible—to track changes in happiness over the full period. The visualization here splits the life satisfaction data from the surveys into sub-periods where the questions remained constant. As we can see, the data is not supportive of a paradox: the correlation between GDP and happiness growth in Japan is positive within comparable survey periods. The reason for the alleged paradox is in fact mismeasurement of how happiness changed over time.</p>   <p>In the US, the explanation is different, but can once again be traced to the underlying data. Specifically, if we look more closely at economic growth in the US over the recent decades, one fact looms large: growth has not benefitted the majority of people. Income inequality in the US is exceptionally high and has been on the rise in the last four decades, with incomes for the median household growing much more slowly than incomes for the top 10%. As a result, trends in aggregate life satisfaction should not be seen as paradoxical: the income and standard of living of the typical US citizen has not grown much in the last couple of decades.

In this visualization, we provide evidence of the cross-country relationship.</p>   <p>Each dot in the scatterplot represents one country. The vertical position of the dots shows national life expectancy at birth, and the horizontal position shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction).</p>   <p>As we can see, there is a strong positive correlation: countries where people tend to live longer are also countries where people tend to say more often that they are satisfied with their lives. A similar relationship holds for other health outcomes (e.g. <a href="https://ourworldindata.org/grapher/life-satisfaction-vs-child-mortality">life satisfaction tends to be higher in countries with lower child mortality</a>).</p>   <p>The relationship plotted in the chart clearly reflects more than just the link between health and happiness, since countries with high life expectancy also tend to be countries with many other distinct characteristics. However, the positive correlation between life expectancy and life satisfaction remains after controlling for observable country characteristics, such as incomes and social protection. You can read more about this in the <a href="http://worldhappiness.report/">World Happiness Report 2017</a>, specifically the discussion in Chapter 2.</p>   <iframe src="https://ourworldindata.org/grapher/life-satisfaction-vs-life-expectancy" width="“300”" height="“150”"></iframe>   <h3>Mental health and happiness</h3>   <p>When trying to discern a relationship between <a href="https://owid.cloud/mental-health">mental health</a> and happiness, it is important to distinguish between macro and micro-level correlations. When we look at macro-level, <a rel="“noopener” noopener noreferrer" href="https://ourworldindata.org/grapher/depression-vs-self-reported-life-satisfaction" target="_blank">cross-country trends</a> in the prevalence of mental health disorders such as depression versus self-reported life satisfaction there is no clear relationship: it does not appear that countries with higher depression rates have lower self-reported happiness.</p>   <p>However, when we look at micro-level, within-country correlations the data tells a different story. In this visualization, we provide evidence of the relationship between health and subjective well-being within countries—specifically; we focus here on mental health and self-reported life satisfaction.</p>   <p>Each bar in the visualization measures the extent to which mental illness (depression and anxiety) is associated with self-reported life satisfaction, once we control for physical illness and other factors such as income and education. In other words, the bars show a ‘conditional correlation’—the strength of the link between mental illness and happiness after accounting for other factors.</p>   <p>The negative values show that people who have been diagnosed with depression or anxiety tend to be more likely to have lower self-reported life satisfaction.</p>   <p>The size of the coefficients, particularly in the US, and Australia, tell us that the relationship we observe is very strong. For context, in the UK, the US and Australia the magnitude of the correlation between mental illness and life satisfaction is <a href="https://ourworldindata.org/grapher/correlation-income-and-life-satisfaction">higher than the magnitude for the correlation between income and life satisfaction</a>.</p>   <p>Clearly, this correlation is likely the result of a two-way relationship: depressed and anxious people are less likely to be happy, and unhappy people are more likely to be depressed or anxious. Nevertheless, it is still important to bear in mind that anxiety, depression and unhappiness often go together.</p>   <p>Other studies provide further evidence of not only the negative correlation between depression and life satisfaction (i.e individuals with more severe depression report lower life satisfaction), but also evidence that treatment and improvement in depression are linked to increases in self-reported life satisfaction.{ref}Koivumaa‐Honkanen, H., Honkanen, R., Antikainen, R., Hintikka, J., Laukkanen, E., Honkalampi, K., & Viinamäki, H.

(2008){ref}Clark, A. E., Diener, E., Georgellis, Y., & Lucas, R. E. (2008). Lags and leads in life satisfaction: A test of the baseline hypothesis. The Economic Journal, 118(529).{/ref} use data from the German Socio-Economic Panel to identify groups of people experiencing significant life and labour market events, and trace how these events affect the evolution of their life satisfaction. The visualization here shows an overview of their main findings. In each individual chart, the red lines mark the estimated effect of a different event at a given point in time (with ‘whiskers’ marking the range of confidence of each estimate).</p>   <p>In all cases the results are split by gender, and time is labeled so that 0 marks the point when the corresponding event took place (with negative and positive values denoting years before and after the event). All estimates control for individual characteristics, so the figures show the effect of the event after controlling for other factors (e.g. income, etc.).</p>   <p>The first point to note is that most events denote the evolution of a latent situation: People grow unhappy in the period building up to a divorce, while they grow happy in the period building up to a marriage.</p>   <p>The second point is that single life events do tend to affect happiness in the short run, but people often adapt to changes. Of course, there are clear differences in the extent to which people adapt. In the case of divorce, life satisfaction first drops, then goes up and stays high. For unemployment, there is a negative shock both in the short and long-run, notably among men. And for marriage, life satisfaction builds up before, and fades out after the wedding.</p>   <p>In general, the evidence suggests that adaptation is an important feature of well-being. Many common but important life events have a modest long-term impact on self-reported happiness. Yet adaptation to some events, such as long-term unemployment, is neither perfect nor immediate.</p>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2017/04/Life-events-on-happiness.png" alt="The effect of life events on life satisfaction"/></figure>   <h3>Does disability correlate with life satisfaction?</h3>   <p>A number of papers have noted that long-term paraplegics do not report themselves as particularly unhappy, when compared to non-paraplegics (see for example the much-cited paper by Brickman, Coates, and Janoff-Bulman, 1978).{ref} Brickman, P., Coates, D., & Janoff-Bulman, R. (1978). Lottery winners and accident victims: Is happiness relative?. Journal of personality and social psychology, 36(8), 917. Chicago. Available online <a href="https://static1.squarespace.com/static/54694fa6e4b0eaec4530f99d/t/54c6fbbae4b057e0ac944d2e/1422326714627/Lottery+winners+and+Accident+Victims.pdf">here</a>.{/ref}</p>   <p>This assertion has received attention because it tells us something about the very meaning of well-being and has important consequences for policy. It is, for example, considered in courts of law with respect to the compensation for disability.</p>   <p>However, comparing differences in self-reported life satisfaction among people with different disability statuses is not an ideal source of evidence regarding the effect of tragedy on happiness. Non-paraplegics are potentially different to paraplegics in ways that are hard to measure. A better source of evidence are longitudinal surveys where people are tracked over time.</p>   <p>Oswald and Powdthavee (2008){ref}Oswald, A. J., & Powdthavee, N. (2008). Does happiness adapt? A longitudinal study of disability with implications for economists and judges. Journal of public economics, 92(5), 1061-1077.{/ref} use data from a longitudinal survey in the UK to explore whether accidents leading to disability imply long-term shocks to life satisfaction.</p>   <p>The chart here, from Oswald and Powdthavee, shows the average reported life satisfaction of a group of people who became seriously disabled (at time T) and remained seriously disabled in the two following years (T+1 and T+2). Here, ‘seriously disabled’ means that disability prevented them from being able to do day-to-day activities.</p>   <p>As we can see—and as the authors show more precisely through econometric techniques—those entering disability suffer a sudden drop in life satisfaction, and recover only partially. This supports the idea that while adaptation plays a role for common life events, the notion of life satisfaction is indeed sensitive to tragic events.</p>   <h6><a id="Life_satisfaction_of_those_entering_serious_disability_BHPS_19962002__Oswald_and_Powdthavee_2006_280"></a>Life satisfaction of those entering serious disability, BHPS 1996-2002 – Oswald and Powdthavee (2006)</h6>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2017/04/Disability-and-happiness-Oswald-and-Powdthavee-2006.png" alt="Life satisfaction of those entering serious disability"/></figure>   <h2>Life satisfaction and society</h2>   <h3>Culture and life satisfaction</h3>   <p>Comparisons of happiness among countries suggest that culture and history shared by people in a given society matter for self-reported life satisfaction. For example, as the chart here shows, culturally and historically similar Latin American countries have a higher subjective well-being than other countries with comparable levels of economic development. (This chart plots self-reported life satisfaction as measured in the 10-point Cantril ladder in the vertical axis, against GDP per capita in the horizontal axis).</p>   <p>Latin America is not a special case in this respect. Ex-communist countries, for example, tend to have lower subjective well-being than other countries with comparable characteristics and levels of economic development.</p>   <p>Academic studies in positive psychology discuss other patterns. Diener and Suh (2002) write: “In recent years cultural differences in subjective well-being have been explored, with a realization that there are profound differences in what makes people happy. Self-esteem, for example, is less strongly associated with life satisfaction, and extraversion is less strongly associated with pleasant affect in collectivist cultures than in individualist cultures”.{ref}Diener, E., Oishi, S., & Lucas, R. E. (2009). Subjective well-being: The science of happiness and life satisfaction. Oxford handbook of positive psychology, 2, 187-194.{/ref}</p>   <p>To our knowledge, there are no rigorous studies exploring the causal mechanisms linking culture and happiness. However, it seems natural to expect that cultural factors shape the way people collectively understand happiness and the meaning of life.</p>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2013/05/continent-version-GDP-pc-vs-Happiness-By-culture.png" alt="Self-reported life satisfaction vs GDP per capita, in 2015"/></figure>   <h3>Sense of freedom and life satisfaction</h3>   <p>A particular channel through which social environment may affect happiness is freedom: the society we live in may crucially affect the availability of options that we have to shape our own life.</p>   <p>This visualization shows the relationship between self-reported sense of freedom and self-reported life satisfaction using data from the <a href="http://www.gallup.com/services/170945/world-poll.aspx">Gallup World Poll</a>. The variable measuring life satisfaction corresponds to country-level averages of survey responses to the Cantril Ladder question (a 0-10 scale, where 10 is the highest level of life satisfaction); while the variable measuring freedom corresponds to the share of people who agree with the statement “In this country, I am satisfied with my freedom to choose what I do with my life”.{ref}To be precise, the Gallup World Poll asks: “In this country, are you satisfied or dissatisfied with your freedom to choose what you do with your life?”{/ref}</p>   <p>As we can see, there is a clear positive relationship: countries where people feel free to choose and control their lives tend to be countries where people are happier. As Inglehart et al. (2008){ref}Inglehart, R., Foa, R., Peterson, C., & Welzel, C. (2008). Development, freedom, and rising happiness: A global perspective (1981–2007). Perspectives on psychological science, 3(4), 264-285.{/ref} show, this positive relationship holds even after we control for other factors, such as incomes and strength of religiosity.</p>   <p>Interestingly, this chart also shows that while there are some countries where the perceived sense of freedom is high but average life satisfaction is low (e.g. Rwanda); there are no countries where the perceived sense of freedom is low but average life satisfaction is high (i.e. there are no countries in the top left area of the chart).</p>   <p>To our knowledge there are no rigorous studies exploring the causal mechanisms linking freedom and happiness. However, it seems natural to expect that self-determination and absence of coercion are important components of what people consider a happy and meaningful life.</p>   <figure class="wp-block-image"><img src="https://ourworldindata.org/app/uploads/2013/05/Happiness-vs-Freedom-in-Your-Life.png" alt="Perception of freedom vs self-reported life satisfaction, 2016"/></figure>   <h3>The link between media and gloominess</h3>   <p>A number of studies have found that there is a link between emotional exposure to negative content in news and changes in mood.</p>   <p>Johnston and Davey (1997),{ref} Johnston, W. M., & Davey, G. C. (1997). The psychological impact of negative TV news bulletins: The catastrophizing of personal worries. British Journal of Psychology, 88(1), 85-91.{/ref} for example, conducted an experiment in which they edited short TV news to display positive, neutral or negative material, and then showed them to three different groups of people. The authors found that people who watched the ‘negative’ clip were more likely to report a sad mood.</p>   <p>This link between emotional content in news and changes in mood is all the more important if we consider that media gatekeepers tend to prefer negative to positive coverage of newsworthy facts (see, for example, Combs and Slovic 1979{ref} Combs, B., & Slovic, P. (1979). Newspaper coverage of causes of death. Journalism Quarterly, 56(4), 837-849.{/ref}).</p>   <p>Of course, mood is not the same as life satisfaction. Yet, as we discuss below in the <a href="https://ourworldindata.org/happiness-and-life-satisfaction/#data-quality-and-measurement">section on measurement and data quality</a>, surveys measuring happiness often do capture emotional aspects of well-being. And in any case, people’s perceptions of what it means to lead a meaningful life are heavily influenced by their expectations of what is possible and likely to occur with their lives; and this has also been shown to depend on media exposure.{ref}Riddle (2010), for example, found that people watching more vivid violent media gave higher estimates of the prevalence of crime in the real world. (Riddle, 2010, “Always on my mind: Exploring how frequent, recent, and vivid television portrayals are used in the formation of social reality judgments.” Media Psychology.) {/ref}</p>   <h2>Data Quality and Measurement</h2>   <h3>Can ‘happiness’ really be measured?</h3>   <p>The most natural way to attempt to measure subjective well-being is to ask people what they think and feel. Indeed, this is the most common approach.</p>   <p>In practice, social scientists tend to rely on questions inquiring directly about happiness, or on questions inquiring about life satisfaction. The former tend to measure the experiential or emotional aspects of well-being (e.g. “I feel very happy”), while the latter tend to measure the evaluative or cognitive aspects of well-being (e.g. “I think I lead a very positive life”).</p>   <p>Self-reports about happiness and life satisfaction are known to correlate with things that people typically associate with contentment, such as cheerfulness and smiling. (In <a href="https://ourworldindata.org/app/uploads/2017/04/Life-Satisfaction-vs-Laugh-Gallup.png">this scatter plot</a> you can see that countries where people have higher self-reported life satisfaction are also countries where people tend to smile more).</p>   <p>Experimental psychologists have also shown that self reports of well-being from surveys turn out to correlate with activity in the parts of the brain associated with pleasure and satisfaction. And various surveys have confirmed that people who say they are happy also tend to sleep better and express positive emotions verbally more frequently.</p>   <p>The following table, adapted from Kahneman and Krueger (2006){ref}Kahneman, D., & Krueger, A. B. (2006). Developments in the measurement of subjective well-being. The journal of economic perspectives, 20(1), 3-24.{/ref}, provides a list of the variables that researchers have found to be related to self-reported happiness and life satisfaction.</p>   <p>The main conclusion from the evidence is that survey-based measures of happiness and life satisfaction do provide a reasonably consistent and reliable picture of subjective well-being.</p>   <table><thead><tr><th scope="col" colSpan="1"><div style="float: left;"> Correlates of high life satisfaction and happiness</div></th></tr></thead><tbody><tr><td colSpan="1" rowspan="1"><div style="float: left;">Smiling frequency</div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;">Smiling with the eyes ("unfakeable smile") </div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;">Ratings of one's happiness made by friends</div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;">Frequent verbal expressions of positive emotions </div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;">Sociability and extraversion</div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;">Sleep quality </div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;">Happiness of close relatives </div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;">Self-reported health </div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;"> High income, and high income rank in a reference group </div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;"> Active involvement in religion</div></td></tr><tr><td colSpan="1" rowspan="1"><div style="float: left;"> Recent positive changes of circumstances (increased income, marriage) </div></td></tr></tbody></table>   <h3>Is ‘life satisfaction’ the same as ‘happiness’?</h3>   <p>In this entry we discuss data and empirical research on happiness and life satisfaction. However, it is important to bear in mind that “life satisfaction” and “happiness” are not really synonyms. And this is of course reflected in the data, since self-reported measures of these two variables come from asking different kinds of questions.</p>   <p>The World Value Survey asks directly about happiness: <em>“Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy, (iv) Not at all happy, (v) Don’t know.”</em></p>   <p>The Gallup World Poll, on the other hand, uses the Cantril Ladder question and asks respondents to evaluate their life: <em>“Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?”</em></p>   <p>As the following scatter plot shows, these two measures are clearly closely related (countries that score high in one measure also tend to score high in the other), yet they are not identical (there is substantial dispersion, with many countries sharing the same score in one variable but diverging in the other).</p>   <p>The differences in responses to questions inquiring about life satisfaction and happiness are consistent with the idea that subjective well-being has two sides: an experiential or emotional side, and an evaluative or cognitive side. Of course, the limits between emotional and cognitive aspects of well-being are blurred in our minds; so in practice both kinds of questions measure both aspects to some degree. Indeed, social scientists often construct ‘subjective well-being indexes’ where they simply average out results from various types of questions.</p>   <iframe src="https://ourworldindata.org/grapher/Happiness-WVS-vs-Gallup" width="“300”" height="“150”"></iframe>   <h3>Are happiness averages really meaningful?</h3>   <p>The most common way to analyze data on happiness consists in taking averages across groups of people. Indeed, cross-country comparisons of self-reported life satisfaction, such as those presented in ‘happiness rankings’, rely on national averages of reports on a scale from 0 to 10 (the Cantril Ladder).</p>   <p>Is it reasonable to take averages of life satisfaction scores? Or, in more technical terms: are self reports of Cantril scores really a cardinal measure of well-being?</p>   <p>The evidence tells us that survey-based reports on the Cantril Ladder do allow cardinal measurement reasonably well—respondents have been found to translate verbal labels, such as ‘very good’ and ‘very bad’, into roughly the same numerical values.{ref}Ferrer‐i‐Carbonell, A., & Frijters, P. (2004). How important is methodology for the estimates of the determinants of happiness?. The Economic Journal, 114(497), 641-659.{/ref} {ref}Van Praag, B.M.S. (1991). ‘Ordinal and cardinal utility: an integration of the two dimensions of the welfare concept’, Journal of Econometrics, vol. 50, pp. 69–89.{/ref}</p>   <p>But as with any other aggregate indicator of social progress, averages need to be interpreted carefully, even if they make sense arithmetically. For example, if we look at happiness by age in a given country, we may see that older people do not appear to be happier than younger people. Yet this may be because the average-by-age figure from the snapshot confounds two factors: the age effect (people from the same cohort do get happier as they grow older, across all cohorts) and the cohort effect (across all ages, earlier generations are less happy than more recent generations). If the cohort effect is very strong, the snapshot can even give a picture that suggests people become <em>less</em> happy as they grow older, even though the exact opposite is actually true within all generations.</p>   <p>This example is in fact taken from the real world: using data from the US, Sutin et al. (2013){ref}Sutin, A. R., Terracciano, A., Milaneschi, Y., An, Y., Ferrucci, L., & Zonderman, A. B. (2013). The effect of birth cohort on well-being The legacy of economic hard times. Psychological science, 0956797612459658.{/ref} showed that self-reported feelings of well-being tend to increase with age across generations, but overall levels of well-being depend on when people were born.</p>   <h4>How much does language matter for cross-country comparisons of happiness?</h4>   <p>Linguistic differences are often seen as a major obstacle for making cross-country comparisons of happiness. However, there is evidence suggesting that comparability issues, at least in respect to language, are less problematic than many people think.</p>   <p>Studies have shown, for example, that in interviews in which respondents are shown pictures or videos of other individuals, respondents can broadly identify whether the individual shown to them was happy or sad; and this is also true when respondents were asked to predict the evaluations of individuals from other cultural communities. (For evidence of this see Sandvik et al., 1993; Diener and Lucas, 1999).{ref}Sandvik, E., Diener, E. and Seidlitz, L. (1993). ‘Subjective well-being: the convergence and stability of self and non self report measures’, Journal of Personality, vol. 61, pp. 317–42. Diener, E. and Lucas, R.E. (1999). ‘Personality and subjective well-being’, in Kahneman et al. (1999) chapter 11.{/ref}</p>   <p>Studies have also shown that ‘indigenous emotions’ across cultures (i.e. feelings that are unique in that they do not have equivalents in the English language) are not experienced any more frequently or differently than common translated emotions. (See Scollon et al. 2005).{ref}Scollon, C. N., Diener, E., Oishi, S., & Biswas-Diener, R. (2004). Emotions across cultures and methods. Journal of cross-cultural psychology, 35(3), 304-326.{/ref}</p>   <p>The conclusion, therefore, seems to be that there is some basic understanding among humans about what it means to be ‘happy’. Survey-based measures of self-reported life satisfaction are informative about cross-country differences, even if these comparisons are obviously noisy.</p>   <h2>Data Sources</h2>   <h4>Cross-country estimates</h4>   <h4><a id="World_Happiness_Report_379"></a>World Happiness Report</h4>   <ul><li><strong>Data:</strong> Country averages of self-reported life satisfaction (Question: Cantril Ladder).</li><li><strong>Underlying source:</strong> Gallup World Poll</li><li><strong>Time span:</strong> 2005-2022</li><li><strong>Available at:</strong> <a href="http://worldhappiness.report/">World Happiness Report</a></li></ul>   <h4><a id="European_Commission__Eurobarometer_Interactive_386"></a>European Commission – Eurobarometer Interactive</h4>   <ul><li><strong>Data:</strong> Life satisfaction (Question: <em>“On the whole are you very satisfied, fairly satisfied, not very satisfied or not at all satisfied with the life you lead ?”</em>)</li><li><strong>Geographical coverage:</strong> EU countries</li><li><strong>Time span:</strong> 1973 - 2015</li><li><strong>Available at:</strong> <a href="http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index">http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index</a></li></ul>   <hr class="wp-block-separator"/>   <h4><a id="The_World_Value_Survey_WVS_395"></a>The World Value Survey (WVS)</h4>   <ul><li><strong>Data:</strong> Happiness and life satisfaction, as well as many other social and cultural characteristics from cross-national time-series surveys.

First published in 2013; substantive revision May 2017. The **French translation** of this entry is here: [Bonheur et satisfaction](https://ourworldindata.org/bonheur-et-satisfaction/) How happy are people today? Were people happier in the past? How satisfied with their lives are people in different societies? And how do our living conditions affect all of this? These are difficult questions to answer; but they are questions that undoubtedly matter for each of us personally. Indeed, today, life satisfaction and happiness are central research areas in the social sciences, including in ‘mainstream’ economics. Social scientists often recommend that measures of subjective well-being should augment the usual measures of economic prosperity, such as [GDP per capita](https://ourworldindata.org/economic-growth).{ref}Particularly important was the [Stiglitz-Sen-Fitoussi Commission](https://en.wikipedia.org/wiki/Commission_on_the_Measurement_of_Economic_Performance_and_Social_Progress). It also relates to Bhutan’s famous measurement of Gross National Happiness (GNH) as indicator of progress (Wikipedia [here](http://en.wikipedia.org/wiki/Gross_national_happiness)).{/ref} But how can happiness be measured? Are there reliable comparisons of happiness across time and space that can give us clues regarding what makes people declare themselves ‘happy’? In this entry, we discuss the data and empirical evidence that might answer these questions. Our focus here will be on survey-based measures of self-reported happiness and life satisfaction. Here is a preview of what the data reveals. 0. Surveys asking people about life satisfaction and happiness do measure subjective well-being with reasonable accuracy. 1. Life satisfaction and happiness vary widely both within and among countries. It only takes a glimpse at the data to see that people are distributed along a wide spectrum of happiness levels. 2. Richer people tend to say they are happier than poorer people; richer countries tend to have higher average happiness levels; and across time, most countries that have experienced sustained economic growth have seen increasing happiness levels. So the evidence suggests that income and life satisfaction tend to go together (which still doesn’t mean they are one and the same). 3. Important life events such as marriage or divorce do affect our happiness, but have surprisingly little long-term impact. The evidence suggests that people tend to adapt to changes. **[See all interactive charts on happiness and life satisfaction ↓](#all-charts)** --- # Happiness across the world today --- The World Happiness Report is a well-known source of cross-country data and research on self-reported life satisfaction. The map here shows, country by country, the ‘happiness scores’ published this report. The underlying source of the happiness scores in the World Happiness Report is the [Gallup World Poll](http://www.gallup.com/services/170945/world-poll.aspx)—a set of nationally representative surveys undertaken in more than 160 countries in over 140 languages. The main life evaluation question asked in the poll is: “Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?” (Also known as the “Cantril Ladder”.) The map plots the average answer that survey-respondents provided to this question in different countries. As with the steps of the ladder, values in the map range from 0 to 10. There are large differences across countries. According to the most recent figures, European countries top the ranking: Finland, Denmark, Iceland, Switzerland and the Netherlands have the highest scores (all with averages above 7). In the same year, the lowest national scores correspond to Afghanistan, Lebanon, Zimbabwe, Rwanda and Botswana (all with average scores below 3.5). You can click on any country on the map to plot time-series for specific countries. As we can see, self-reported life satisfaction correlates with other measures of well-being—richer and healthier countries tend to have higher average happiness scores. (More on this in the section [below](https://ourworldindata.org/happiness-and-life-satisfaction/#correlates-determinants-and-consequences).) <Chart url="https://ourworldindata.org/grapher/happiness-cantril-ladder"/> --- # Happiness over time --- ### Findings from the World Value Survey In addition to the Gallup World Poll (discussed above), the [World Value Survey](http://www.worldvaluessurvey.org/WVSDocumentationWV6.jsp) also provides cross-country data on self-reported life satisfaction. These are the longest available time series of cross-country happiness estimates that include non-European nations. The World Value Survey collects data from a series of representative national surveys covering almost 100 countries, with the earliest estimates dating back to 1981. In these surveys, respondents are asked: “Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy or (iv) Not at all happy”. This visualization plots the share of people answering they are Very happy or Rather happy. As we can see, in the majority of countries the trend is positive: In 49 of the 69 countries with data from two or more surveys, [the most recent observation is higher than the earliest](https://ourworldindata.org/grapher/share-who-say-happy-wvs-first-to-last). In some cases, the improvement has been very large; in Zimbabwe, for example, the share of people who reported being ‘very happy’ or ‘rather happy’ went from 56.4% in 2004 to 82.1% in 2014. <Chart url="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy"/> ### Findings from Eurobarometer The [Eurobarometer](http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/General/index) collects data on life satisfaction as part of their public opinion surveys. For several countries, these surveys have been conducted at least annually for more than 40 years. The visualization here shows the share of people who report being ‘very satisfied’ or ‘fairly satisfied’ with their standards of living, according to this source. Two points are worth emphasizing. First, estimates of life satisfaction often fluctuate around trends. In France, for example, we can see that the overall trend in the period 1974-2016 is positive; yet there is a pattern of ups and downs. And second, despite temporary fluctuations, decade-long trends have been generally positive for most European countries. In most cases, the share of people who say they are ‘very satisfied’ or ‘fairly satisfied’ with their life has gone up over the full survey period.{ref}To be precise, in 27 out of 31 countries with data spanning longer than one decade, the estimate for 2016 is higher than the earliest available estimate.{/ref} Yet there are some clear exceptions, of which Greece is the most notable example. Add Greece to the chart and you can see that in 2007, around 67% of the Greeks said they were satisfied with their life; but five years later, after the financial crisis struck, the corresponding figure was down to 32.4%. Despite recent improvements, Greeks today are on average much less satisfied with their lives than before the financial crisis. No other European country in this dataset has gone through a comparable negative shock. <Chart url="https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy-eurobarometer"/> --- # The distribution of life satisfaction --- ### More than averages—the distribution of life satisfaction scores Most of the studies comparing happiness and life satisfaction among countries focus on averages. However, distributional differences are also important. Life satisfaction is often reported on a scale from 0 to 10, with 10 representing the highest possible level of satisfaction. This is the so-called ‘Cantril Ladder’. This visualization shows how responses are distributed across steps in this ladder. In each case, the height of bars is proportional to the fraction of answers at each score. Each differently-colored distribution refers to a world region; and for each region, we have overlaid the distribution for the entire world as a reference. These plots show that in sub-Saharan Africa—the region with the lowest average scores–the distributions are consistently to the left of those in Europe. In economics lingo, we observe that the distribution of scores in European countries _stochastically dominates_ the distribution in sub-Saharan Africa. This means that the share of people who are ‘happy’ is lower in sub-Saharan Africa than in Western Europe, independently of which score in the ladder we use as a threshold to define ‘happy’. Similar comparisons can be made by contrasting other regions with high average scores (e.g. North America, Australia and New Zealand) against those with low average scores (e.g. South Asia). Another important point to notice is that the distribution of self-reported life satisfaction in Latin America is high across the board—it is consistently to the right of other regions with roughly comparable income levels, such as Central and Eastern Europe. This is part of a broader pattern: Latin American countries tend to have a higher subjective well-being than other countries with comparable levels of economic development. As we will see in the section on [social environment](https://ourworldindata.org/happiness-and-life-satisfaction/#the-relationship-between-culture-and-life-satisfaction), culture and history matter for self-reported life satisfaction. <Image filename="The-distribution-of-life-satisfaction.png" alt="Distribution of self-reported life satisfaction by world region"/> If you are interested in data on country-level distributions of scores, the [Pew Global Attitudes Survey](http://www.pewglobal.org/question-search/?qid=365&cntIDs=&stdIDs=) provides such figures for more than 40 countries. --- # (Mis)perceptions about others' happiness --- We tend to underestimate the average happiness of people around us. The visualization shown demonstrates this for countries around the world, using data from Ipsos' [Perils of Perception](http://perils.ipsos.com/)—a cross-country survey asking people to guess what others in their country have answered to the happiness question in the World Value Survey. The horizontal axis in this chart shows the actual share of people who said they are 'Very Happy' or 'Rather Happy' in the World Value Survey; the vertical axis shows the average _guess_ of the same number (i.e. the average guess that respondents made of the share of people reporting to be 'Very Happy' or 'Rather Happy' in their country). If respondents would have guessed the correct share, all observations would fall on the red 45-degree line. But as we can see, all countries are far below the 45-degree line. In other words, people in every country underestimated the self-reported happiness of others. The most extreme deviations are in Asia—South Koreans think that 24% of people report being happy, when in reality 90% do. The highest guesses in this sample (Canada and Norway) are 60%—this is lower than the lowest actual value of self-reported happiness in any country in the sample (corresponding to Hungary at 69%). <Image filename="Happiness-of-others.png" alt=""/> Why do people get their guesses so wrong? It's not as simple as brushing aside these numbers by saying they reflect differences in 'actual' vs. reported happiness. One possible explanation is that people tend to misreport their own happiness, therefore the average guesses might be a correct indicator of true life satisfaction (and an incorrect indicator of _reported_ life satisfaction). However, for this to be true, people would have to commonly misreport their own happiness while assuming that others do _not_ misreport theirs. And people are not bad at judging the well-being of other people who they know: There is substantial evidence showing that [ratings of one's happiness made by friends correlate with one's happiness](https://ourworldindata.org/happiness-and-life-satisfaction/#can-happiness-really-be-measured), and that [people are generally good at evaluating emotions from simply watching facial expressions](https://ourworldindata.org/happiness-and-life-satisfaction/#how-much-does-language-matter-for-cross-country-comparisons-of-happiness). An alternative explanation is that this mismatch is grounded in the well-established fact that people tend to be positive about themselves, but negative about other people they don't know.It has been observed in other contexts that people can be optimistic about their own future, while at the same time being deeply pessimistic about the future of their nation or the world. We discuss this phenomenon in more detail in our entry on [optimism and pessimism](https://ourworldindata.org/optimism-pessimism/), specifically in a section dedicated to [individual optimism and social pessimism](https://ourworldindata.org/optimism-pessimism/#individual-optimism-and-social-pessimism). --- # Differences in happiness within countries --- ## East and West Germany In global surveys of happiness and life satisfaction, [Germany usually ranks high](https://ourworldindata.org/grapher/happiness-cantril-ladder). However, these national averages mask large inequalities. In the map shown we focus on regional inequalities—specifically the gap in life satisfaction between West and East Germany. This map plots self-reported life satisfaction in Germany (using the [0-10 Cantril Ladder question](https://ourworldindata.org/happiness-and-life-satisfaction/#is-life-satisfaction-the-same-as-happiness)), aggregating averages scores at the level of [Federal States](https://en.wikipedia.org/wiki/States_of_Germany).{ref}In some cases, the underlying data had multiple average estimates for the same territory (e.g. Baden and Württemberg were treated as different entities). In these cases the map shows the average between these two observations. Details can be found in [this file](https://ourworldindata.org/app/uploads/2017/04/Germany-happiness-data.xlsx){/ref} What stands out is a clear divide between the East and the West, along the political division that existed before the reunification of Germany in 1990. For example, the difference in levels between neighboring Schleswig-Holstein (in West Germany) and Mecklenburg-Vorpommern (in East Germany) are similar to the difference between [Sweden and the US](https://ourworldindata.org/grapher/happiness-cantril-ladder) – a considerable contrast in self-reported life satisfaction. <Image filename="Germany-happiness-Gluecksatlas.png" alt=""/> Several academic studies have looked more closely at this 'happiness gap' in Germany using data from more detailed surveys, such as the German Socio-Economic Panel (e.g. Petrunyk and Pfeifer 2016).{ref}Petrunyk, I., & Pfeifer, C. (2016). Life satisfaction in Germany after reunification: Additional insights on the pattern of convergence. Jahrbücher für Nationalökonomie und Statistik, 236(2), 217-239.{/ref} These studies provide two main insights: First, the gap is partly driven by differences in household income and employment. But this is not the only aspect; even after controlling for socioeconomic and demographic differences, the East-West gap remains significant. ### Germany's happiness gap over time And second, the gap has been narrowing in recent years, as the chart shows. In fact, the finding that the gap is narrowing is true both for the raw average differences, as well as for the 'conditional differences' (i.e. the differences that are estimated after controlling for socioeconomic and demographic characteristics). ##### Trends in life satisfaction for East and West Germany, 1992-2013 <Image filename="East-West-German-Happiness-gaps-Petrunyk-and-Pfeifer-2016.png" alt=""/> The observation that socioeconomic and demographic differences do not fully predict the observed East-West differences in self-reported happiness is related to a broader empirical phenomenon: Culture and history matter for self-reported life satisfaction—and in particular, ex-communist countries tend to have a lower subjective well-being than other countries with comparable levels of economic development. ## Happiness inequality ### Happiness inequality in the US and other rich countries The General Social Survey (GSS) in the US is a survey administered to a nationally representative sample of about 1,500 respondents each year since 1972, and is an important source of information on long-run trends of self-reported life satisfaction in the country.{ref}The GSS asks people a very similar question to the World Value Survey: “Taken all together, how would you say things are these days—would you say that you are very happy, pretty happy, or not too happy?”{/ref} Using this source, Stevenson and Wolfers (2008){ref}Stevenson, Betsey, and Justin Wolfers. “Happiness inequality in the United States.” The Journal of Legal Studies 37.S2 (2008): S33-S79. An ungated earlier version of the paper is available [here](https://www.econstor.eu/bitstream/10419/35143/1/576953326.pdf).{/ref} show that while the national average has remained broadly constant, inequality in happiness has fallen substantially in the US in recent decades. The authors further note that this is true both when we think about inequality in terms of the dispersion of answers, and also when we think about inequality in terms of gaps between demographic groups. They note that two-thirds of the black-white happiness gap has been eroded (although today white Americans remain happier on average, even after controlling for differences in education and income), and the gender happiness gap has disappeared entirely (women used to be slightly happier than men, but they are becoming less happy, and today there is no statistical difference once we control for other characteristics).{ref}These results have been discussed in various blogs. Freakonomics provides a quick and interesting overview of the debate, specifically with regard to [gender gaps](http://freakonomics.com/2007/10/01/why-are-women-so-unhappy/).{/ref} The results from Stevenson and Wolfers are consistent with other studies looking at changes of happiness inequality (or life satisfaction inequality) over time. In particular, researchers have noted that there is a correlation between economic growth and reductions in happiness inequality—even when [income inequality](https://ourworldindata.org/income-inequality/) is increasing at the same time. The visualization here uses data from Clark, Fleche and Senik (2015){ref}Clark, Andrew E., Sarah Flèche, and Claudia Senik. “Economic growth evens out happiness: Evidence from six surveys.” Review of Income and Wealth (2015). An ungated earlier version of the paper is available [here](http://eprints.lse.ac.uk/60530/1/dp1306.pdf){/ref} shows this. It plots the evolution of happiness inequality within a selection of rich countries that experienced uninterrupted GDP growth. In this chart, happiness inequality is measured by the dispersion — specifically the standard deviation — of answers in the World Value Survey. As we can see, there is a broad negative trend. In their paper the authors show that the trend is positive in countries with falling GDP. <Chart url="https://ourworldindata.org/grapher/evolution-of-happiness-inequality-within-countries-during-periods-of-uninterrupted-economic-growth"/> Why could it be that happiness inequality falls with rising income inequality? Clark, Fleche, and Senik argue that part of the reason is that the growth of national income allows for the greater provision of public goods, which in turn tighten the distribution of subjective well-being. This can still be consistent with growing income inequality, since public goods such as [better health](https://ourworldindata.org/health-meta/) affect incomes and well-being differently. Another possibility is that economic growth in rich countries has translated into a more diverse society in terms of cultural expressions (e.g. through the emergence of alternative lifestyles), which has allowed people to converge in happiness even if they diverge in incomes, tastes and consumption. Steven Quartz and Annette Asp explain this hypothesis in a [New York Times article](https://www.nytimes.com/2015/04/12/opinion/sunday/unequal-yet-happy.html?smid=nytcore-ipad-share&smprod=nytcore-ipad&_r=0), discussing evidence from experimental psychology. --- # The link between happiness and income --- ## The link across countries ### Higher national incomes go together with higher average life satisfaction If we compare life satisfaction reports from around the world at any given point in time, we immediately see that countries with higher average national incomes tend to have higher average life satisfaction scores. In other words: People in richer countries tend to report higher life satisfaction than people in poorer countries. The scatter plot here shows this. Each dot in the visualization represents one country. The vertical position of the dots shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction); while the horizontal position shows GDP per capita based on purchasing power parity (i.e. GDP per head after adjusting for inflation and cross-country price differences). This correlation holds even if we control for other factors: Richer countries tend to have higher average self-reported life satisfaction than poorer countries that are comparable in terms of demographics and other measurable characteristics. You can read more about this in the [World Happiness Report 2017](http://worldhappiness.report/), specifically the discussion in Chapter 2. As we show below, income and happiness also tend to go together [within countries](https://ourworldindata.org/happiness-and-life-satisfaction/#higher-personal-incomes-go-together-with-higher-self-reported-life-satisfaction) and [across time](https://ourworldindata.org/happiness-and-life-satisfaction/#economic-growth-and-happiness). <Chart url="https://ourworldindata.org/grapher/gdp-vs-happiness"/> ## The link within countries ### Higher personal incomes go together with higher self-reported life satisfaction Above we point out that richer countries tend to be happier than poorer countries. Here we show that the same tends to be true within countries: richer people within a country tend to be happier than poorer people in the same country. The visualisations here show us this this by looking at happiness by income quintiles. Firstly we show each country in individual panels: within each panel is a connected scatter plot for a specific country. This means that for each country, we observe a line joining five points: each point marks the average income within an income quintile (horizontal axis) against the average self-reported life satisfaction of people at that income quintile (vertical axis). What does this visualization tell us? We see that in all cases lines are upward sloping: people in higher income quintiles tend to have higher average life satisfaction. Yet in some countries the lines are steep and linear (e.g. in Costa Rica richer people are happier than poorer people across the whole income distribution); while in some countries the lines are less steep and non-linear (e.g. the richest group of people in the Dominican Republic is as happy as the second-richest group). <Image filename="Happiness-by-Income-Quintiles-Small-Multiples.png" alt="Self-reported life-satisfaction across the income distribution"/> In a second visualization we present the same data, but instead of plotting each country separately, showing all countries in one grid. The resulting connected scatter plot may be messy, resembling a ‘spaghetti’ chart, but it is helpful to confirm the overall pattern: despite kinks here and there, lines are by and large upward sloping. <Image filename="Happiness-across-income-distribution.png" alt="Self-reported life satisfactino across the income distribution, country by country"/> ## Looking across and within countries ### A snapshot of the correlation between income and happiness—between and within countries Do income and happiness tend to go together? The visualization here shows that the answer to this question is yes, both within and across countries. It may take a minute to wrap your head around this visualization, but once you do, you can see that it handily condenses the key information from the previous three charts into one. To show the income-happiness correlation across countries, the chart plots the relationship between self-reported life satisfaction on the vertical axis and GDP per capita on the horizontal axis. Each country is an arrow on the grid, and the location of the arrow tells us the corresponding combination of average income and average happiness. To show the income-happiness correlation _within_ countries, each arrow has a slope corresponding to the correlation between household incomes and self-reported life satisfaction within that country. In other words: the slope of the arrow shows how strong the relationship between income and life satisfaction is within that country. ([This chart](https://ourworldindata.org/app/uploads/2013/05/South-Africa-inequality-of-income-and-happiness-as-example.png) gives you a visual example of how the arrows were constructed for each country). {ref}To be precise, the gradients correspond, country by country, to the regression coefficients between income quintiles and the related average life satisfaction reported by people within each income quintile.{/ref} If an arrow points northeast, that means richer people tend to report higher life satisfaction than poorer people in the same country. If an arrow is flat (i.e. points east), that means rich people are on average just as happy as poorer people in the same country. As we can see, there is a very clear pattern: richer countries tend to be happier than poorer countries (observations are lined up around an upward-sloping trend), and richer people within countries tend to be happier than poorer people in the same countries (arrows are consistently pointing northeast). <Image filename="GDP-vs-Happiness-and-gradient-within-countries.png" alt="People in richer countries tend to be happier and within all countries richer people tend to be happier"/> It’s important to note that the horizontal axis is measured in a logarithmic scale. The cross-country relationship we would observe in a linear scale would be different, since at high national income levels, slightly higher national incomes are associated with a smaller increase in average happiness than at low levels of national incomes. In other words, the cross-country relationship between income and happiness is not linear on income (it is ‘log-linear’). We use the logarithmic scale to highlight two key facts: (i) at no point in the global income distribution is the relationship flat; and (ii) a doubling of the average income is associated with roughly the same increase in the reported life-satisfaction, irrespective of the position in the global distribution. These findings have been explored in more detail in a number of recent academic studies. Importantly, the much-cited paper by Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online [here](https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF). {/ref} shows that these correlations hold even after controlling for various country characteristics such as demographic composition of the population, and are robust to different sources of data and types of subjective well-being measures. ## Economic growth and happiness In the charts above we show that there is robust evidence of a strong correlation between income and happiness across and within countries at fixed points in time. Here we want to show that, while less strong, there is also a correlation between income and happiness across time. Or, put differently, as countries get richer, the population tends to report higher average life satisfaction. The chart shown here uses data from the World Value Survey to plot the evolution of national average incomes and national average happiness over time. To be specific, this chart shows the share of people who say they are ‘very happy’ or ‘rather happy’ in the World Value Survey (vertical axis), against GDP per head (horizontal axis). Each country is drawn as a line joining first and last available observations across all survey waves.{ref}The dataset includes observations for Egypt. However, we have excluded these observations from our analysis. This is because the survey for Egypt in the wave labeled 2014 is from 2012, which was a year characterized by extreme political instability in that country.{/ref} As we can see, countries that experience economic growth also tend to experience happiness growth across waves in the World Value Survey. And this is a correlation that holds after controlling for other factors that also change over time (in [this chart](https://ourworldindata.org/app/uploads/2017/04/Stevenson-Wolfers-2008-%E2%80%93-Happiness-and-Growth-744x550.png) from Stevenson and Wolfers (2008) you can see how changes in GDP per capita compare to changes in life satisfaction after accounting for changes in demographic composition and other variables). An important point to note here is that economic growth and happiness growth tend to go together _on average_. Some countries in some periods experience economic growth without increasing happiness. The experience of the US in recent decades is a case in point. These instances may seem paradoxical given the evidence—we explore this question in the following section. <Image filename="Inc-vs-Happiness-over-time.png" alt=""/> ## The Easterlin Paradox The observation that economic growth does not always go together with increasing life satisfaction was first made by Richard Easterlin in the 1970s. Since then, there has been much discussion over what came to be known as the ‘Easterlin Paradox’. At the heart of the paradox was the fact that richer countries tend to have higher self-reported happiness, yet in some countries for which repeated surveys were available over the course of the 1970s, happiness was not increasing with rising national incomes. This combination of empirical findings was paradoxical because the cross-country evidence (countries with higher incomes tended to have higher self-reported happiness) did not, in some cases, fit the evidence over time (countries seemed not to get happier as national incomes increased). Notably, Easterlin and other researchers relied on data from the US and Japan to support this seemingly perplexing observation. If we look closely at the data underpinning the trends in these two countries, however, these cases are not in fact paradoxical. Let us begin with the case of Japan. There, the earliest available data on self-reported life satisfaction came from the so-called ‘Life in Nation surveys’, which date back to 1958. At first glance, this source suggests that mean life satisfaction remained flat over a period of spectacular economic growth (see for example [this chart](http://ourworldindata.org/app/uploads/2013/05/mean-subjective-well-being-japan-1958-1987-easterlin-in-land-michalos-and-sirgy-ed-2011.png) from Easterlin and Angelescu 2011).{ref}R.A. Easterlin and L. Angelescu – ‘Modern Economic Growth and Quality of Life: Cross-Sectional and Time Series Evidence’ in Land, Michalos, and Sirgy (ed.) (2011) – Handbook of Social Indicators and Quality of Life Research. Springer.{/ref} Digging a bit deeper, however, we find that things are more complex. Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online [here](https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF). {/ref} show that the life satisfaction questions in the ‘Life in Nation surveys’ changed over time, making it difficult—if not impossible—to track changes in happiness over the full period. The visualization here splits the life satisfaction data from the surveys into sub-periods where the questions remained constant. As we can see, the data is not supportive of a paradox: the correlation between GDP and happiness growth in Japan is positive within comparable survey periods. The reason for the alleged paradox is in fact mismeasurement of how happiness changed over time. In the US, the explanation is different, but can once again be traced to the underlying data. Specifically, if we look more closely at economic growth in the US over the recent decades, one fact looms large: growth has not benefitted the majority of people. Income inequality in the US is exceptionally high and has been on the rise in the last four decades, with incomes for the median household growing much more slowly than incomes for the top 10%. As a result, trends in aggregate life satisfaction should not be seen as paradoxical: the income and standard of living of the typical US citizen has not grown much in the last couple of decades. (You can read more about this in our entry on [inequality and incomes across the distribution](https://ourworldindata.org/incomes-across-the-distribution/#the-us-incomes-for-most-households-stagnate-inequality-increases-constantly).) ##### [](undefined)GDP per capita vs Life satisfaction across survey questions, Japan, 1958-2007 – Stevenson and Wolfers (2008){ref}Chart from Stevenson B, Wolfers J (2008) - Economic Growth and Subjective Well-Being: Reassessing the Easterlin Paradox. Brookings Paper Econ Activ 2008 (Spring):1–87. Underlying data source: Life in Nation surveys, 1958–2007. Note from the authors: “The series in each of the four panels reports responses to a different life satisfaction question, and therefore comparisons should be made only within each panel.

In this visualization, we provide evidence of the cross-country relationship. Each dot in the scatterplot represents one country. The vertical position of the dots shows national life expectancy at birth, and the horizontal position shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction). As we can see, there is a strong positive correlation: countries where people tend to live longer are also countries where people tend to say more often that they are satisfied with their lives. A similar relationship holds for other health outcomes (e.g. [life satisfaction tends to be higher in countries with lower child mortality](https://ourworldindata.org/grapher/life-satisfaction-vs-child-mortality)). The relationship plotted in the chart clearly reflects more than just the link between health and happiness, since countries with high life expectancy also tend to be countries with many other distinct characteristics. However, the positive correlation between life expectancy and life satisfaction remains after controlling for observable country characteristics, such as incomes and social protection. You can read more about this in the [World Happiness Report 2017](http://worldhappiness.report/), specifically the discussion in Chapter 2. <Chart url="https://ourworldindata.org/grapher/life-satisfaction-vs-life-expectancy"/> ## Mental health and happiness When trying to discern a relationship between [mental health](https://owid.cloud/mental-health) and happiness, it is important to distinguish between macro and micro-level correlations. When we look at macro-level, [cross-country trends](https://ourworldindata.org/grapher/depression-vs-self-reported-life-satisfaction) in the prevalence of mental health disorders such as depression versus self-reported life satisfaction there is no clear relationship: it does not appear that countries with higher depression rates have lower self-reported happiness. However, when we look at micro-level, within-country correlations the data tells a different story. In this visualization, we provide evidence of the relationship between health and subjective well-being within countries—specifically; we focus here on mental health and self-reported life satisfaction. Each bar in the visualization measures the extent to which mental illness (depression and anxiety) is associated with self-reported life satisfaction, once we control for physical illness and other factors such as income and education. In other words, the bars show a ‘conditional correlation’—the strength of the link between mental illness and happiness after accounting for other factors. The negative values show that people who have been diagnosed with depression or anxiety tend to be more likely to have lower self-reported life satisfaction. The size of the coefficients, particularly in the US, and Australia, tell us that the relationship we observe is very strong. For context, in the UK, the US and Australia the magnitude of the correlation between mental illness and life satisfaction is [higher than the magnitude for the correlation between income and life satisfaction](https://ourworldindata.org/grapher/correlation-income-and-life-satisfaction). Clearly, this correlation is likely the result of a two-way relationship: depressed and anxious people are less likely to be happy, and unhappy people are more likely to be depressed or anxious. Nevertheless, it is still important to bear in mind that anxiety, depression and unhappiness often go together. Other studies provide further evidence of not only the negative correlation between depression and life satisfaction (i.e individuals with more severe depression report lower life satisfaction), but also evidence that treatment and improvement in depression are linked to increases in self-reported life satisfaction.{ref}Koivumaa‐Honkanen, H., Honkanen, R., Antikainen, R., Hintikka, J., Laukkanen, E., Honkalampi, K., & Viinamäki, H.

When asked to visualize happy and sad situations, researchers found individuals with depression to show notably less facial muscle activity relative to those without - a suggestion sign of both lower emotivity and disengagement.{ref}Gehricke, J. G., & Shapiro, D. (2000). Reduced facial expression and social context in major depression: discrepancies between facial muscle activity and self-reported emotion.

Do people tend to adapt to common life events by converging back to a baseline level of happiness? Clark et al. (2008){ref}Clark, A. E., Diener, E., Georgellis, Y., & Lucas, R. E. (2008). Lags and leads in life satisfaction: A test of the baseline hypothesis. The Economic Journal, 118(529).{/ref} use data from the German Socio-Economic Panel to identify groups of people experiencing significant life and labour market events, and trace how these events affect the evolution of their life satisfaction. The visualization here shows an overview of their main findings. In each individual chart, the red lines mark the estimated effect of a different event at a given point in time (with ‘whiskers’ marking the range of confidence of each estimate). In all cases the results are split by gender, and time is labeled so that 0 marks the point when the corresponding event took place (with negative and positive values denoting years before and after the event). All estimates control for individual characteristics, so the figures show the effect of the event after controlling for other factors (e.g. income, etc.). The first point to note is that most events denote the evolution of a latent situation: People grow unhappy in the period building up to a divorce, while they grow happy in the period building up to a marriage. The second point is that single life events do tend to affect happiness in the short run, but people often adapt to changes. Of course, there are clear differences in the extent to which people adapt. In the case of divorce, life satisfaction first drops, then goes up and stays high. For unemployment, there is a negative shock both in the short and long-run, notably among men. And for marriage, life satisfaction builds up before, and fades out after the wedding. In general, the evidence suggests that adaptation is an important feature of well-being. Many common but important life events have a modest long-term impact on self-reported happiness. Yet adaptation to some events, such as long-term unemployment, is neither perfect nor immediate. <Image filename="Life-events-on-happiness.png" alt="The effect of life events on life satisfaction"/> ## Does disability correlate with life satisfaction? A number of papers have noted that long-term paraplegics do not report themselves as particularly unhappy, when compared to non-paraplegics (see for example the much-cited paper by Brickman, Coates, and Janoff-Bulman, 1978).{ref} Brickman, P., Coates, D., & Janoff-Bulman, R. (1978). Lottery winners and accident victims: Is happiness relative?. Journal of personality and social psychology, 36(8), 917. Chicago. Available online [here](https://static1.squarespace.com/static/54694fa6e4b0eaec4530f99d/t/54c6fbbae4b057e0ac944d2e/1422326714627/Lottery+winners+and+Accident+Victims.pdf).{/ref} This assertion has received attention because it tells us something about the very meaning of well-being and has important consequences for policy. It is, for example, considered in courts of law with respect to the compensation for disability. However, comparing differences in self-reported life satisfaction among people with different disability statuses is not an ideal source of evidence regarding the effect of tragedy on happiness. Non-paraplegics are potentially different to paraplegics in ways that are hard to measure. A better source of evidence are longitudinal surveys where people are tracked over time. Oswald and Powdthavee (2008){ref}Oswald, A. J., & Powdthavee, N. (2008). Does happiness adapt? A longitudinal study of disability with implications for economists and judges. Journal of public economics, 92(5), 1061-1077.{/ref} use data from a longitudinal survey in the UK to explore whether accidents leading to disability imply long-term shocks to life satisfaction. The chart here, from Oswald and Powdthavee, shows the average reported life satisfaction of a group of people who became seriously disabled (at time T) and remained seriously disabled in the two following years (T+1 and T+2). Here, ‘seriously disabled’ means that disability prevented them from being able to do day-to-day activities. As we can see—and as the authors show more precisely through econometric techniques—those entering disability suffer a sudden drop in life satisfaction, and recover only partially. This supports the idea that while adaptation plays a role for common life events, the notion of life satisfaction is indeed sensitive to tragic events. ##### [](undefined)Life satisfaction of those entering serious disability, BHPS 1996-2002 – Oswald and Powdthavee (2006) <Image filename="Disability-and-happiness-Oswald-and-Powdthavee-2006.png" alt="Life satisfaction of those entering serious disability"/> --- # Life satisfaction and society --- ## Culture and life satisfaction Comparisons of happiness among countries suggest that culture and history shared by people in a given society matter for self-reported life satisfaction. For example, as the chart here shows, culturally and historically similar Latin American countries have a higher subjective well-being than other countries with comparable levels of economic development. (This chart plots self-reported life satisfaction as measured in the 10-point Cantril ladder in the vertical axis, against GDP per capita in the horizontal axis). Latin America is not a special case in this respect. Ex-communist countries, for example, tend to have lower subjective well-being than other countries with comparable characteristics and levels of economic development. Academic studies in positive psychology discuss other patterns. Diener and Suh (2002) write: “In recent years cultural differences in subjective well-being have been explored, with a realization that there are profound differences in what makes people happy. Self-esteem, for example, is less strongly associated with life satisfaction, and extraversion is less strongly associated with pleasant affect in collectivist cultures than in individualist cultures”.{ref}Diener, E., Oishi, S., & Lucas, R. E. (2009). Subjective well-being: The science of happiness and life satisfaction. Oxford handbook of positive psychology, 2, 187-194.{/ref} To our knowledge, there are no rigorous studies exploring the causal mechanisms linking culture and happiness. However, it seems natural to expect that cultural factors shape the way people collectively understand happiness and the meaning of life. <Image filename="continent-version-GDP-pc-vs-Happiness-By-culture.png" alt="Self-reported life satisfaction vs GDP per capita, in 2015"/> ## Sense of freedom and life satisfaction A particular channel through which social environment may affect happiness is freedom: the society we live in may crucially affect the availability of options that we have to shape our own life. This visualization shows the relationship between self-reported sense of freedom and self-reported life satisfaction using data from the [Gallup World Poll](http://www.gallup.com/services/170945/world-poll.aspx). The variable measuring life satisfaction corresponds to country-level averages of survey responses to the Cantril Ladder question (a 0-10 scale, where 10 is the highest level of life satisfaction); while the variable measuring freedom corresponds to the share of people who agree with the statement “In this country, I am satisfied with my freedom to choose what I do with my life”.{ref}To be precise, the Gallup World Poll asks: “In this country, are you satisfied or dissatisfied with your freedom to choose what you do with your life?”{/ref} As we can see, there is a clear positive relationship: countries where people feel free to choose and control their lives tend to be countries where people are happier. As Inglehart et al. (2008){ref}Inglehart, R., Foa, R., Peterson, C., & Welzel, C. (2008). Development, freedom, and rising happiness: A global perspective (1981–2007). Perspectives on psychological science, 3(4), 264-285.{/ref} show, this positive relationship holds even after we control for other factors, such as incomes and strength of religiosity. Interestingly, this chart also shows that while there are some countries where the perceived sense of freedom is high but average life satisfaction is low (e.g. Rwanda); there are no countries where the perceived sense of freedom is low but average life satisfaction is high (i.e. there are no countries in the top left area of the chart). To our knowledge there are no rigorous studies exploring the causal mechanisms linking freedom and happiness. However, it seems natural to expect that self-determination and absence of coercion are important components of what people consider a happy and meaningful life. <Image filename="Happiness-vs-Freedom-in-Your-Life.png" alt="Perception of freedom vs self-reported life satisfaction, 2016"/> ## The link between media and gloominess A number of studies have found that there is a link between emotional exposure to negative content in news and changes in mood. Johnston and Davey (1997),{ref} Johnston, W. M., & Davey, G. C. (1997). The psychological impact of negative TV news bulletins: The catastrophizing of personal worries. British Journal of Psychology, 88(1), 85-91.{/ref} for example, conducted an experiment in which they edited short TV news to display positive, neutral or negative material, and then showed them to three different groups of people. The authors found that people who watched the ‘negative’ clip were more likely to report a sad mood. This link between emotional content in news and changes in mood is all the more important if we consider that media gatekeepers tend to prefer negative to positive coverage of newsworthy facts (see, for example, Combs and Slovic 1979{ref} Combs, B., & Slovic, P. (1979). Newspaper coverage of causes of death. Journalism Quarterly, 56(4), 837-849.{/ref}). Of course, mood is not the same as life satisfaction. Yet, as we discuss below in the [section on measurement and data quality](https://ourworldindata.org/happiness-and-life-satisfaction/#data-quality-and-measurement), surveys measuring happiness often do capture emotional aspects of well-being. And in any case, people’s perceptions of what it means to lead a meaningful life are heavily influenced by their expectations of what is possible and likely to occur with their lives; and this has also been shown to depend on media exposure.{ref}Riddle (2010), for example, found that people watching more vivid violent media gave higher estimates of the prevalence of crime in the real world. (Riddle, 2010, “Always on my mind: Exploring how frequent, recent, and vivid television portrayals are used in the formation of social reality judgments.” Media Psychology.) {/ref} --- # Data Quality and Measurement --- ## Can ‘happiness’ really be measured? The most natural way to attempt to measure subjective well-being is to ask people what they think and feel. Indeed, this is the most common approach. In practice, social scientists tend to rely on questions inquiring directly about happiness, or on questions inquiring about life satisfaction. The former tend to measure the experiential or emotional aspects of well-being (e.g. “I feel very happy”), while the latter tend to measure the evaluative or cognitive aspects of well-being (e.g. “I think I lead a very positive life”). Self-reports about happiness and life satisfaction are known to correlate with things that people typically associate with contentment, such as cheerfulness and smiling. (In [this scatter plot](https://ourworldindata.org/app/uploads/2017/04/Life-Satisfaction-vs-Laugh-Gallup.png) you can see that countries where people have higher self-reported life satisfaction are also countries where people tend to smile more). Experimental psychologists have also shown that self reports of well-being from surveys turn out to correlate with activity in the parts of the brain associated with pleasure and satisfaction. And various surveys have confirmed that people who say they are happy also tend to sleep better and express positive emotions verbally more frequently. The following table, adapted from Kahneman and Krueger (2006){ref}Kahneman, D., & Krueger, A. B. (2006). Developments in the measurement of subjective well-being. The journal of economic perspectives, 20(1), 3-24.{/ref}, provides a list of the variables that researchers have found to be related to self-reported happiness and life satisfaction. The main conclusion from the evidence is that survey-based measures of happiness and life satisfaction do provide a reasonably consistent and reliable picture of subjective well-being. <div class="raw-html-table__container"><table><thead><tr><th scope="col" colspan="1"><div style="float: left;"> Correlates of high life satisfaction and happiness</div></th></tr></thead><tbody><tr><td colspan="1" rowspan="1"><div style="float: left;">Smiling frequency</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Smiling with the eyes ("unfakeable smile") </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Ratings of one's happiness made by friends</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Frequent verbal expressions of positive emotions </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Sociability and extraversion</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Sleep quality </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Happiness of close relatives </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;">Self-reported health </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;"> High income, and high income rank in a reference group </div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;"> Active involvement in religion</div></td></tr><tr><td colspan="1" rowspan="1"><div style="float: left;"> Recent positive changes of circumstances (increased income, marriage) </div></td></tr></tbody></table></div> ## Is ‘life satisfaction’ the same as ‘happiness’? In this entry we discuss data and empirical research on happiness and life satisfaction. However, it is important to bear in mind that “life satisfaction” and “happiness” are not really synonyms. And this is of course reflected in the data, since self-reported measures of these two variables come from asking different kinds of questions. The World Value Survey asks directly about happiness: _“Taking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy, (iv) Not at all happy, (v) Don’t know.”_ The Gallup World Poll, on the other hand, uses the Cantril Ladder question and asks respondents to evaluate their life: _“Please imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?”_ As the following scatter plot shows, these two measures are clearly closely related (countries that score high in one measure also tend to score high in the other), yet they are not identical (there is substantial dispersion, with many countries sharing the same score in one variable but diverging in the other). The differences in responses to questions inquiring about life satisfaction and happiness are consistent with the idea that subjective well-being has two sides: an experiential or emotional side, and an evaluative or cognitive side. Of course, the limits between emotional and cognitive aspects of well-being are blurred in our minds; so in practice both kinds of questions measure both aspects to some degree. Indeed, social scientists often construct ‘subjective well-being indexes’ where they simply average out results from various types of questions. <Chart url="https://ourworldindata.org/grapher/Happiness-WVS-vs-Gallup"/> ## Are happiness averages really meaningful? The most common way to analyze data on happiness consists in taking averages across groups of people. Indeed, cross-country comparisons of self-reported life satisfaction, such as those presented in ‘happiness rankings’, rely on national averages of reports on a scale from 0 to 10 (the Cantril Ladder). Is it reasonable to take averages of life satisfaction scores? Or, in more technical terms: are self reports of Cantril scores really a cardinal measure of well-being? The evidence tells us that survey-based reports on the Cantril Ladder do allow cardinal measurement reasonably well—respondents have been found to translate verbal labels, such as ‘very good’ and ‘very bad’, into roughly the same numerical values.{ref}Ferrer‐i‐Carbonell, A., & Frijters, P. (2004). How important is methodology for the estimates of the determinants of happiness?. The Economic Journal, 114(497), 641-659.{/ref} {ref}Van Praag, B.M.S. (1991). ‘Ordinal and cardinal utility: an integration of the two dimensions of the welfare concept’, Journal of Econometrics, vol. 50, pp. 69–89.{/ref} But as with any other aggregate indicator of social progress, averages need to be interpreted carefully, even if they make sense arithmetically. For example, if we look at happiness by age in a given country, we may see that older people do not appear to be happier than younger people. Yet this may be because the average-by-age figure from the snapshot confounds two factors: the age effect (people from the same cohort do get happier as they grow older, across all cohorts) and the cohort effect (across all ages, earlier generations are less happy than more recent generations). If the cohort effect is very strong, the snapshot can even give a picture that suggests people become _less_ happy as they grow older, even though the exact opposite is actually true within all generations. This example is in fact taken from the real world: using data from the US, Sutin et al. (2013){ref}Sutin, A. R., Terracciano, A., Milaneschi, Y., An, Y., Ferrucci, L., & Zonderman, A. B. (2013). The effect of birth cohort on well-being The legacy of economic hard times. Psychological science, 0956797612459658.{/ref} showed that self-reported feelings of well-being tend to increase with age across generations, but overall levels of well-being depend on when people were born. ### How much does language matter for cross-country comparisons of happiness? Linguistic differences are often seen as a major obstacle for making cross-country comparisons of happiness. However, there is evidence suggesting that comparability issues, at least in respect to language, are less problematic than many people think. Studies have shown, for example, that in interviews in which respondents are shown pictures or videos of other individuals, respondents can broadly identify whether the individual shown to them was happy or sad; and this is also true when respondents were asked to predict the evaluations of individuals from other cultural communities. (For evidence of this see Sandvik et al., 1993; Diener and Lucas, 1999).{ref}Sandvik, E., Diener, E. and Seidlitz, L. (1993). ‘Subjective well-being: the convergence and stability of self and non self report measures’, Journal of Personality, vol. 61, pp. 317–42. Diener, E. and Lucas, R.E. (1999). ‘Personality and subjective well-being’, in Kahneman et al. (1999) chapter 11.{/ref} Studies have also shown that ‘indigenous emotions’ across cultures (i.e. feelings that are unique in that they do not have equivalents in the English language) are not experienced any more frequently or differently than common translated emotions. (See Scollon et al. 2005).{ref}Scollon, C. N., Diener, E., Oishi, S., & Biswas-Diener, R. (2004). Emotions across cultures and methods. Journal of cross-cultural psychology, 35(3), 304-326.{/ref} The conclusion, therefore, seems to be that there is some basic understanding among humans about what it means to be ‘happy’. Survey-based measures of self-reported life satisfaction are informative about cross-country differences, even if these comparisons are obviously noisy. --- # Data Sources --- ### Cross-country estimates ### [](undefined)World Happiness Report * **Data:** Country averages of self-reported life satisfaction (Question: Cantril Ladder). * **Underlying source:** Gallup World Poll * **Time span:** 2005-2022 * **Available at:**[World Happiness Report](http://worldhappiness.report/) ### [](undefined)European Commission – Eurobarometer Interactive * **Data:** Life satisfaction (Question: _“On the whole are you very satisfied, fairly satisfied, not very satisfied or not at all satisfied with the life you lead ?”_) * **Geographical coverage:** EU countries * **Time span:** 1973 - 2015 * **Available at:**[http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index](http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index) ### [](undefined)The World Value Survey (WVS) * **Data:** Happiness and life satisfaction, as well as many other social and cultural characteristics from cross-national time-series surveys.

Were people happier in the past? How satisfied with their lives are people in different societies? And how do our living conditions affect all of this?</p>\n\n\n\n<p>These are difficult questions to answer; but they are questions that undoubtedly matter for each of us personally. Indeed, today, life satisfaction and happiness are central research areas in the social sciences, including in \u2018mainstream\u2019 economics.</p>\n\n\n\n<p>Social scientists often recommend that measures of subjective well-being should augment the usual measures of economic prosperity, such as <a rel=\"noopener noreferrer\" href=\"https://ourworldindata.org/economic-growth\" target=\"_blank\">GDP per capita</a>.{ref}Particularly important was the <a rel=\"noreferrer noopener\" href=\"https://en.wikipedia.org/wiki/Commission_on_the_Measurement_of_Economic_Performance_and_Social_Progress\" target=\"_blank\">Stiglitz-Sen-Fitoussi Commission</a>. It also relates to Bhutan\u2019s famous measurement of Gross National Happiness (GNH) as indicator of progress (Wikipedia <a rel=\"noreferrer noopener\" href=\"http://en.wikipedia.org/wiki/Gross_national_happiness\" target=\"_blank\">here</a>).{/ref} But how can happiness be measured? Are there reliable comparisons of happiness across time and space that can give us clues regarding what makes people declare themselves \u2018happy\u2019?</p>\n\n\n\n<p>In this entry, we discuss the data and empirical evidence that might answer these questions. Our focus here will be on survey-based measures of self-reported happiness and life satisfaction. Here is a preview of what the data reveals.</p>\n\n\n\n<ol><li>Surveys asking people about life satisfaction and happiness do measure subjective well-being with reasonable accuracy.</li><li>Life satisfaction and happiness vary widely both within and among countries. It only takes a glimpse at the data to see that people are distributed along a wide spectrum of happiness levels.</li><li>Richer people tend to say they are happier than poorer people; richer countries tend to have higher average happiness levels; and across time, most countries that have experienced sustained economic growth have seen increasing happiness levels. So the evidence suggests that income and life satisfaction tend to go together (which still doesn\u2019t mean they are one and the same).</li><li>Important life events such as marriage or divorce do affect our happiness, but have surprisingly little long-term impact.

The map here shows, country by country, the \u2018happiness scores\u2019 published this report.</p>\n\n\n\n<p>The underlying source of the happiness scores in the World Happiness Report is the <a href=\"http://www.gallup.com/services/170945/world-poll.aspx\" target=\"_blank\" rel=\"noopener noreferrer\">Gallup World Poll</a>\u2014a set of nationally representative surveys undertaken in more than 160 countries in over 140 languages. The main life evaluation question asked in the poll is: \u201cPlease imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?\u201d (Also known as the \u201cCantril Ladder\u201d.)</p>\n\n\n\n<p>The map plots the average answer that survey-respondents provided to this question in different countries. As with the steps of the ladder, values in the map range from 0 to 10.</p>\n\n\n\n<p>There are large differences across countries. According to the most recent figures, European countries top the ranking: Finland, Denmark, Iceland, Switzerland and the Netherlands have the highest scores (all with averages above 7). In the same year, the lowest national scores correspond to Afghanistan, Lebanon, Zimbabwe, Rwanda and Botswana (all with average scores below 3.5).</p>\n\n\n\n<p>You can click on any country on the map to plot time-series for specific countries.</p>\n\n\n\n<p>As we can see, self-reported life satisfaction correlates with other measures of well-being\u2014richer and healthier countries tend to have higher average happiness scores. (More on this in the section <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#correlates-determinants-and-consequences\">below</a>.)</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/happiness-cantril-ladder\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h2>Happiness over time</h2>\n\n\n\n<h4>Findings from the World Value Survey</h4>\n\n\n\n<p>In addition to the Gallup World Poll (discussed above), the <a href=\"http://www.worldvaluessurvey.org/WVSDocumentationWV6.jsp\">World Value Survey</a> also provides cross-country data on self-reported life satisfaction. These are the longest available time series of cross-country happiness estimates that include non-European nations.</p>\n\n\n\n<p>The World Value Survey collects data from a series of representative national surveys covering almost 100 countries, with the earliest estimates dating back to 1981. In these surveys, respondents are asked: \u201cTaking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy or (iv) Not at all happy\u201d. This visualization plots the share of people answering they are Very happy or Rather happy.</p>\n\n\n\n<p>As we can see, in the majority of countries the trend is positive: In 49 of the 69 countries with data from two or more surveys, <a href=\"https://ourworldindata.org/grapher/share-who-say-happy-wvs-first-to-last\">the most recent observation is higher than the earliest</a>. In some cases, the improvement has been very large; in Zimbabwe, for example, the share of people who reported being \u2018very happy\u2019 or \u2018rather happy\u2019 went from 56.4% in 2004 to 82.1% in 2014.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h4>Findings from Eurobarometer</h4>\n\n\n\n<p>The <a href=\"http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/General/index\">Eurobarometer</a> collects data on life satisfaction as part of their public opinion surveys. For several countries, these surveys have been conducted at least annually for more than 40 years. The visualization here shows the share of people who report being \u2018very satisfied\u2019 or \u2018fairly satisfied\u2019 with their standards of living, according to this source.</p>\n\n\n\n<p>Two points are worth emphasizing. First, estimates of life satisfaction often fluctuate around trends. In France, for example, we can see that the overall trend in the period 1974-2016 is positive; yet there is a pattern of ups and downs. And second, despite temporary fluctuations, decade-long trends have been generally positive for most European countries.</p>\n\n\n\n<p>In most cases, the share of people who say they are \u2018very satisfied\u2019 or \u2018fairly satisfied\u2019 with their life has gone up over the full survey period.{ref}To be precise, in 27 out of 31 countries with data spanning longer than one decade, the estimate for 2016 is higher than the earliest available estimate.{/ref} Yet there are some clear exceptions, of which Greece is the most notable example. Add Greece to the chart and you can see that in 2007, around 67% of the Greeks said they were satisfied with their life; but five years later, after the financial crisis struck, the corresponding figure was down to 32.4%. Despite recent improvements, Greeks today are on average much less satisfied with their lives than before the financial crisis. No other European country in this dataset has gone through a comparable negative shock.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/share-of-people-who-say-they-are-happy-eurobarometer\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h2>The distribution of life satisfaction</h2>\n\n\n\n<h4>More than averages\u2014the distribution of life satisfaction scores</h4>\n\n\n\n<p>Most of the studies comparing happiness and life satisfaction among countries focus on averages. However, distributional differences are also important.</p>\n\n\n\n<p>Life satisfaction is often reported on a scale from 0 to 10, with 10 representing the highest possible level of satisfaction. This is the so-called \u2018Cantril Ladder\u2019. This visualization shows how responses are distributed across steps in this ladder. In each case, the height of bars is proportional to the fraction of answers at each score. Each differently-colored distribution refers to a world region; and for each region, we have overlaid the distribution for the entire world as a reference.</p>\n\n\n\n<p>These plots show that in sub-Saharan Africa\u2014the region with the lowest average scores\u2013the distributions are consistently to the left of those in Europe. In economics lingo, we observe that the distribution of scores in European countries <em>stochastically dominates</em> the distribution in sub-Saharan Africa.</p>\n\n\n\n<p>This means that the share of people who are \u2018happy\u2019 is lower in sub-Saharan Africa than in Western Europe, independently of which score in the ladder we use as a threshold to define \u2018happy\u2019. Similar comparisons can be made by contrasting other regions with high average scores (e.g. North America, Australia and New Zealand) against those with low average scores (e.g. South Asia).</p>\n\n\n\n<p>Another important point to notice is that the distribution of self-reported life satisfaction in Latin America is high across the board\u2014it is consistently to the right of other regions with roughly comparable income levels, such as Central and Eastern Europe.</p>\n\n\n\n<p>This is part of a broader pattern: Latin American countries tend to have a higher subjective well-being than other countries with comparable levels of economic development. As we will see in the section on <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#the-relationship-between-culture-and-life-satisfaction\">social environment</a>, culture and history matter for self-reported life satisfaction.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/The-distribution-of-life-satisfaction.png\" alt=\"Distribution of self-reported life satisfaction by world region\"/></figure>\n\n\n\n<p>If you are interested in data on country-level distributions of scores, the <a href=\"http://www.pewglobal.org/question-search/?qid=365&amp;cntIDs=&amp;stdIDs=\">Pew Global Attitudes Survey</a> provides such figures for more than 40 countries.</p>\n\n\n\n<h2>(Mis)perceptions about others&#8217; happiness</h2>\n\n\n\n<p>We tend to underestimate the average happiness of people around us. The visualization shown demonstrates this for countries around the world, using data from Ipsos&#8217; <a rel=\"noopener noreferrer\" href=\"http://perils.ipsos.com/\" target=\"_blank\">Perils of Perception</a>\u2014a cross-country survey asking people to guess what others in their country have answered to the happiness question in the World Value Survey.</p>\n\n\n\n<p>The horizontal axis in this chart shows the actual share of people who said they are &#8216;Very Happy&#8217; or &#8216;Rather Happy&#8217; in the World Value Survey; the vertical axis shows the average <em>guess</em> of the same number (i.e. the average guess that respondents made of the share of people reporting to be &#8216;Very Happy&#8217; or &#8216;Rather Happy&#8217; in their country).</p>\n\n\n\n<p>If respondents would have guessed the correct share, all observations would fall on the red 45-degree line. But as we can see, all countries are far below the 45-degree line. In other words, people in every country underestimated the self-reported happiness of others. The most extreme deviations are in Asia\u2014South Koreans think that 24% of people report being happy, when in reality 90% do.</p>\n\n\n\n<p>The highest guesses in this sample (Canada and Norway) are 60%\u2014this is lower than the lowest actual value of self-reported happiness in any country in the sample (corresponding to Hungary at 69%).</p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others.png\"><img loading=\"lazy\" width=\"550\" height=\"550\" src=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-of-others-550x550.png\" alt=\"\" class=\"wp-image-11310\" srcset=\"https://owid.cloud/app/uploads/2017/04/Happiness-of-others-550x550.png 550w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-150x150.png 150w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-400x400.png 400w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-768x768.png 768w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-32x32.png 32w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-50x50.png 50w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-64x64.png 64w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-96x96.png 96w, https://owid.cloud/app/uploads/2017/04/Happiness-of-others-128x128.png 128w\" sizes=\"(max-width: 550px) 100vw, 550px\" /></a></figure></div>\n\n\n\n<p>Why do people get their guesses so wrong? It&#8217;s not as simple as brushing aside these numbers by saying they reflect differences in &#8216;actual&#8217; vs. reported happiness.</p>\n\n\n\n<p>One possible explanation is that people tend to misreport their own happiness, therefore the average guesses might be a correct indicator of true life satisfaction (and an incorrect indicator of <em>reported</em> life satisfaction). However, for this to be true, people would have to commonly misreport their own happiness while assuming that others do <em>not</em> misreport theirs.</p>\n\n\n\n<p>And people are not bad at judging the well-being of other people who they know: There is substantial evidence showing that <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#can-happiness-really-be-measured\">ratings of one&#8217;s happiness made by friends correlate with one&#8217;s happiness</a>, and that <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#how-much-does-language-matter-for-cross-country-comparisons-of-happiness\">people are generally good at evaluating emotions from simply watching facial expressions</a>.</p>\n\n\n\n<p>An alternative explanation is that this mismatch is grounded in the well-established fact that people tend to be positive about themselves, but negative about other people they don&#8217;t know.It has been observed in other contexts that people can be optimistic about their own future, while at the same time being deeply pessimistic about the future of their nation or the world. We discuss this phenomenon in more detail in our entry on <a href=\"https://ourworldindata.org/optimism-pessimism/\">optimism and pessimism</a>, specifically in a section dedicated to <a href=\"https://ourworldindata.org/optimism-pessimism/#individual-optimism-and-social-pessimism\">individual optimism and social pessimism</a>.</p>\n\n\n\n<h2>Differences in happiness within countries</h2>\n\n\n\n<h3>East and West Germany</h3>\n\n\n\n<p>In global surveys of happiness and life satisfaction, <a rel=\"noopener noreferrer\" href=\"https://ourworldindata.org/grapher/happiness-cantril-ladder\" target=\"_blank\">Germany usually ranks high</a>.

They note that two-thirds of the black-white happiness gap has been eroded (although today white Americans remain happier on average, even after controlling for differences in education and income), and the gender happiness gap has disappeared entirely (women used to be slightly happier than men, but they are becoming less happy, and today there is no statistical difference once we control for other characteristics).{ref}These results have been discussed in various blogs. Freakonomics provides a quick and interesting overview of the debate, specifically with regard to <a rel=\"noreferrer noopener\" href=\"http://freakonomics.com/2007/10/01/why-are-women-so-unhappy/\" target=\"_blank\">gender gaps</a>.{/ref}</p>\n\n\n\n<p>The results from Stevenson and Wolfers are consistent with other studies looking at changes of happiness inequality (or life satisfaction inequality) over time. In particular, researchers have noted that there is a correlation between economic growth and reductions in happiness inequality\u2014even when <a rel=\"noopener noreferrer\" href=\"https://ourworldindata.org/income-inequality/\" target=\"_blank\">income inequality</a> is increasing at the same time. The visualization here uses data from Clark, Fleche and Senik (2015){ref}Clark, Andrew E., Sarah Fl\u00e8che, and Claudia Senik. \u201cEconomic growth evens out happiness: Evidence from six surveys.\u201d Review of Income and Wealth (2015).

This can still be consistent with growing income inequality, since public goods such as <a href=\"https://ourworldindata.org/health-meta/\">better health</a> affect incomes and well-being differently.</p>\n\n\n\n<p>Another possibility is that economic growth in rich countries has translated into a more diverse society in terms of cultural expressions (e.g. through the emergence of alternative lifestyles), which has allowed people to converge in happiness even if they diverge in incomes, tastes and consumption. Steven Quartz and Annette Asp explain this hypothesis in a <a href=\"https://www.nytimes.com/2015/04/12/opinion/sunday/unequal-yet-happy.html?smid=nytcore-ipad-share&amp;smprod=nytcore-ipad&amp;_r=0\" target=\"_blank\" rel=\"noopener noreferrer\">New York Times article</a>, discussing evidence from experimental psychology.</p>\n\n\n\n<h2>The link between happiness and income</h2>\n\n\n\n<h3>The link across countries</h3>\n\n\n\n<h4>Higher national incomes go together with higher average life satisfaction</h4>\n\n\n\n<p>If we compare life satisfaction reports from around the world at any given point in time, we immediately see that countries with higher average national incomes tend to have higher average life satisfaction scores. In other words: People in richer countries tend to report higher life satisfaction than people in poorer countries. The scatter plot here shows this.</p>\n\n\n\n<p>Each dot in the visualization represents one country. The vertical position of the dots shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction); while the horizontal position shows GDP per capita based on purchasing power parity (i.e. GDP per head after adjusting for inflation and cross-country price differences).</p>\n\n\n\n<p>This correlation holds even if we control for other factors: Richer countries tend to have higher average self-reported life satisfaction than poorer countries that are comparable in terms of demographics and other measurable characteristics. You can read more about this in the <a href=\"http://worldhappiness.report/\">World Happiness Report 2017</a>, specifically the discussion in Chapter 2.</p>\n\n\n\n<p>As we show below, income and happiness also tend to go together <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#higher-personal-incomes-go-together-with-higher-self-reported-life-satisfaction\">within countries</a> and <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#economic-growth-and-happiness\">across time</a>.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/gdp-vs-happiness\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h3>The link within countries</h3>\n\n\n\n<h4>Higher personal incomes go together with higher self-reported life satisfaction</h4>\n\n\n\n<p>Above we point out that richer countries tend to be happier than poorer countries. Here we show that the same tends to be true within countries: richer people within a country tend to be happier than poorer people in the same country. The visualisations here show us this this by looking at happiness by income quintiles.</p>\n\n\n\n<p>Firstly we show each country in individual panels: within each panel is a connected scatter plot for a specific country. This means that for each country, we observe a line joining five points: each point marks the average income within an income quintile (horizontal axis) against the average self-reported life satisfaction of people at that income quintile (vertical axis).</p>\n\n\n\n<p>What does this visualization tell us? We see that in all cases lines are upward sloping: people in higher income quintiles tend to have higher average life satisfaction. Yet in some countries the lines are steep and linear (e.g. in Costa Rica richer people are happier than poorer people across the whole income distribution); while in some countries the lines are less steep and non-linear (e.g. the richest group of people in the Dominican Republic is as happy as the second-richest group).</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-by-Income-Quintiles-Small-Multiples.png\" alt=\"Self-reported life-satisfaction across the income distribution\"/></figure>\n\n\n\n<p>In a second visualization we present the same data, but instead of plotting each country separately, showing all countries in one grid.</p>\n\n\n\n<p>The resulting connected scatter plot may be messy, resembling a \u2018spaghetti\u2019 chart, but it is helpful to confirm the overall pattern: despite kinks here and there, lines are by and large upward sloping.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Happiness-across-income-distribution.png\" alt=\"Self-reported life satisfactino across the income distribution, country by country\"/></figure>\n\n\n\n<h3>Looking across and within countries</h3>\n\n\n\n<h4>A snapshot of the correlation between income and happiness\u2014between and within countries</h4>\n\n\n\n<p>Do income and happiness tend to go together? The visualization here shows that the answer to this question is yes, both within and across countries.</p>\n\n\n\n<p>It may take a minute to wrap your head around this visualization, but once you do, you can see that it handily condenses the key information from the previous three charts into one.</p>\n\n\n\n<p>To show the income-happiness correlation across countries, the chart plots the relationship between self-reported life satisfaction on the vertical axis and GDP per capita on the horizontal axis. Each country is an arrow on the grid, and the location of the arrow tells us the corresponding combination of average income and average happiness.</p>\n\n\n\n<p>To show the income-happiness correlation <em>within</em> countries, each arrow has a slope corresponding to the correlation between household incomes and self-reported life satisfaction within that country. In other words: the slope of the arrow shows how strong the relationship between income and life satisfaction is within that country. (<a href=\"https://ourworldindata.org/app/uploads/2013/05/South-Africa-inequality-of-income-and-happiness-as-example.png\">This chart</a> gives you a visual example of how the arrows were constructed for each country). {ref}To be precise, the gradients correspond, country by country, to the regression coefficients between income quintiles and the related average life satisfaction reported by people within each income quintile.{/ref}</p>\n\n\n\n<p>If an arrow points northeast, that means richer people tend to report higher life satisfaction than poorer people in the same country. If an arrow is flat (i.e. points east), that means rich people are on average just as happy as poorer people in the same country.</p>\n\n\n\n<p>As we can see, there is a very clear pattern: richer countries tend to be happier than poorer countries (observations are lined up around an upward-sloping trend), and richer people within countries tend to be happier than poorer people in the same countries (arrows are consistently pointing northeast).</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/GDP-vs-Happiness-and-gradient-within-countries.png\" alt=\"People in richer countries tend to be happier and within all countries richer people tend to be happier\"/></figure>\n\n\n\n<p>It\u2019s important to note that the horizontal axis is measured in a logarithmic scale. The cross-country relationship we would observe in a linear scale would be different, since at high national income levels, slightly higher national incomes are associated with a smaller increase in average happiness than at low levels of national incomes. In other words, the cross-country relationship between income and happiness is not linear on income (it is \u2018log-linear\u2019). We use the logarithmic scale to highlight two key facts: (i) at no point in the global income distribution is the relationship flat; and (ii) a doubling of the average income is associated with roughly the same increase in the reported life-satisfaction, irrespective of the position in the global distribution.</p>\n\n\n\n<p>These findings have been explored in more detail in a number of recent academic studies. Importantly, the much-cited paper by Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online <a rel=\"noreferrer noopener\" href=\"https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF\" target=\"_blank\">here</a>. {/ref} shows that these correlations hold even after controlling for various country characteristics such as demographic composition of the population, and are robust to different sources of data and types of subjective well-being measures.</p>\n\n\n\n<h3>Economic growth and happiness</h3>\n\n\n\n<p>In the charts above we show that there is robust evidence of a strong correlation between income and happiness across and within countries at fixed points in time. Here we want to show that, while less strong, there is also a correlation between income and happiness across time. Or, put differently, as countries get richer, the population tends to report higher average life satisfaction.</p>\n\n\n\n<p>The chart shown here uses data from the World Value Survey to plot the evolution of national average incomes and national average happiness over time. To be specific, this chart shows the share of people who say they are \u2018very happy\u2019 or \u2018rather happy\u2019 in the World Value Survey (vertical axis), against GDP per head (horizontal axis). Each country is drawn as a line joining first and last available observations across all survey waves.{ref}The dataset includes observations for Egypt. However, we have excluded these observations from our analysis. This is because the survey for Egypt in the wave labeled 2014 is from 2012, which was a year characterized by extreme political instability in that country.{/ref}</p>\n\n\n\n<p>As we can see, countries that experience economic growth also tend to experience happiness growth across waves in the World Value Survey. And this is a correlation that holds after controlling for other factors that also change over time (in <a href=\"https://ourworldindata.org/app/uploads/2017/04/Stevenson-Wolfers-2008-%E2%80%93-Happiness-and-Growth-744x550.png\" target=\"_blank\" rel=\"noopener noreferrer\">this chart</a> from Stevenson and Wolfers (2008) you can see how changes in GDP per capita compare to changes in life satisfaction after accounting for changes in demographic composition and other variables).</p>\n\n\n\n<p>An important point to note here is that economic growth and happiness growth tend to go together <em>on average</em>. Some countries in some periods experience economic growth without increasing happiness. The experience of the US in recent decades is a case in point. These instances may seem paradoxical given the evidence\u2014we explore this question in the following section.</p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" width=\"3000\" height=\"2204\" src=\"https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time.png\" alt=\"\" class=\"wp-image-43177\" srcset=\"https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time.png 3000w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-400x294.png 400w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-749x550.png 749w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-150x110.png 150w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-768x564.png 768w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-1536x1128.png 1536w, https://owid.cloud/app/uploads/2021/05/Inc-vs-Happiness-over-time-2048x1505.png 2048w\" sizes=\"(max-width: 3000px) 100vw, 3000px\" /></figure>\n\n\n\n<h3>The Easterlin Paradox</h3>\n\n\n\n<p>The observation that economic growth does not always go together with increasing life satisfaction was first made by Richard Easterlin in the 1970s. Since then, there has been much discussion over what came to be known as the \u2018Easterlin Paradox\u2019.</p>\n\n\n\n<p>At the heart of the paradox was the fact that richer countries tend to have higher self-reported happiness, yet in some countries for which repeated surveys were available over the course of the 1970s, happiness was not increasing with rising national incomes. This combination of empirical findings was paradoxical because the cross-country evidence (countries with higher incomes tended to have higher self-reported happiness) did not, in some cases, fit the evidence over time (countries seemed not to get happier as national incomes increased).</p>\n\n\n\n<p>Notably, Easterlin and other researchers relied on data from the US and Japan to support this seemingly perplexing observation. If we look closely at the data underpinning the trends in these two countries, however, these cases are not in fact paradoxical.</p>\n\n\n\n<p>Let us begin with the case of Japan. There, the earliest available data on self-reported life satisfaction came from the so-called \u2018Life in Nation surveys\u2019, which date back to 1958. At first glance, this source suggests that mean life satisfaction remained flat over a period of spectacular economic growth (see for example <a href=\"http://ourworldindata.org/app/uploads/2013/05/mean-subjective-well-being-japan-1958-1987-easterlin-in-land-michalos-and-sirgy-ed-2011.png\">this chart</a> from Easterlin and Angelescu 2011).{ref}R.A.

(2011) \u2013 Handbook of Social Indicators and Quality of Life Research. Springer.{/ref} Digging a bit deeper, however, we find that things are more complex.</p>\n\n\n\n<p>Stevenson and Wolfers (2008){ref}Stevenson, B. and Wolfers, J. (2008). Economic growth and subjective well-being: Reassessing the Easterlin Paradox. Brookings Papers on Economic Activity, 1-87. An earlier version is available online <a href=\"https://www.econstor.eu/bitstream/10419/26439/1/577841831.PDF\">here</a>. {/ref} show that the life satisfaction questions in the \u2018Life in Nation surveys\u2019 changed over time, making it difficult\u2014if not impossible\u2014to track changes in happiness over the full period. The visualization here splits the life satisfaction data from the surveys into sub-periods where the questions remained constant. As we can see, the data is not supportive of a paradox: the correlation between GDP and happiness growth in Japan is positive within comparable survey periods. The reason for the alleged paradox is in fact mismeasurement of how happiness changed over time.</p>\n\n\n\n<p>In the US, the explanation is different, but can once again be traced to the underlying data. Specifically, if we look more closely at economic growth in the US over the recent decades, one fact looms large: growth has not benefitted the majority of people. Income inequality in the US is exceptionally high and has been on the rise in the last four decades, with incomes for the median household growing much more slowly than incomes for the top 10%. As a result, trends in aggregate life satisfaction should not be seen as paradoxical: the income and standard of living of the typical US citizen has not grown much in the last couple of decades.

In this visualization, we provide evidence of the cross-country relationship.</p>\n\n\n\n<p>Each dot in the scatterplot represents one country. The vertical position of the dots shows national life expectancy at birth, and the horizontal position shows national average self-reported life satisfaction in the Cantril Ladder (a scale ranging from 0-10 where 10 is the highest possible life satisfaction).</p>\n\n\n\n<p>As we can see, there is a strong positive correlation: countries where people tend to live longer are also countries where people tend to say more often that they are satisfied with their lives. A similar relationship holds for other health outcomes (e.g. <a href=\"https://ourworldindata.org/grapher/life-satisfaction-vs-child-mortality\">life satisfaction tends to be higher in countries with lower child mortality</a>).</p>\n\n\n\n<p>The relationship plotted in the chart clearly reflects more than just the link between health and happiness, since countries with high life expectancy also tend to be countries with many other distinct characteristics. However, the positive correlation between life expectancy and life satisfaction remains after controlling for observable country characteristics, such as incomes and social protection. You can read more about this in the <a href=\"http://worldhappiness.report/\">World Happiness Report 2017</a>, specifically the discussion in Chapter 2.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/life-satisfaction-vs-life-expectancy\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h3>Mental health and happiness</h3>\n\n\n\n<p>When trying to discern a relationship between <a href=\"https://owid.cloud/mental-health\">mental health</a> and happiness, it is important to distinguish between macro and micro-level correlations. When we look at macro-level, <a rel=\"\u201cnoopener\u201d noopener noreferrer\" href=\"https://ourworldindata.org/grapher/depression-vs-self-reported-life-satisfaction\" target=\"_blank\">cross-country trends</a> in the prevalence of mental health disorders such as depression versus self-reported life satisfaction there is no clear relationship: it does not appear that countries with higher depression rates have lower self-reported happiness.</p>\n\n\n\n<p>However, when we look at micro-level, within-country correlations the data tells a different story. In this visualization, we provide evidence of the relationship between health and subjective well-being within countries\u2014specifically; we focus here on mental health and self-reported life satisfaction.</p>\n\n\n\n<p>Each bar in the visualization measures the extent to which mental illness (depression and anxiety) is associated with self-reported life satisfaction, once we control for physical illness and other factors such as income and education. In other words, the bars show a \u2018conditional correlation\u2019\u2014the strength of the link between mental illness and happiness after accounting for other factors.</p>\n\n\n\n<p>The negative values show that people who have been diagnosed with depression or anxiety tend to be more likely to have lower self-reported life satisfaction.</p>\n\n\n\n<p>The size of the coefficients, particularly in the US, and Australia, tell us that the relationship we observe is very strong. For context, in the UK, the US and Australia the magnitude of the correlation between mental illness and life satisfaction is <a href=\"https://ourworldindata.org/grapher/correlation-income-and-life-satisfaction\">higher than the magnitude for the correlation between income and life satisfaction</a>.</p>\n\n\n\n<p>Clearly, this correlation is likely the result of a two-way relationship: depressed and anxious people are less likely to be happy, and unhappy people are more likely to be depressed or anxious. Nevertheless, it is still important to bear in mind that anxiety, depression and unhappiness often go together.</p>\n\n\n\n<p>Other studies provide further evidence of not only the negative correlation between depression and life satisfaction (i.e individuals with more severe depression report lower life satisfaction), but also evidence that treatment and improvement in depression are linked to increases in self-reported life satisfaction.{ref}Koivumaa\u2010Honkanen, H., Honkanen, R., Antikainen, R., Hintikka, J., Laukkanen, E., Honkalampi, K., &amp; Viinam\u00e4ki, H.

(2008){ref}Clark, A. E., Diener, E., Georgellis, Y., &amp; Lucas, R. E. (2008). Lags and leads in life satisfaction: A test of the baseline hypothesis. The Economic Journal, 118(529).{/ref} use data from the German Socio-Economic Panel to identify groups of people experiencing significant life and labour market events, and trace how these events affect the evolution of their life satisfaction. The visualization here shows an overview of their main findings. In each individual chart, the red lines mark the estimated effect of a different event at a given point in time (with \u2018whiskers\u2019 marking the range of confidence of each estimate).</p>\n\n\n\n<p>In all cases the results are split by gender, and time is labeled so that 0 marks the point when the corresponding event took place (with negative and positive values denoting years before and after the event). All estimates control for individual characteristics, so the figures show the effect of the event after controlling for other factors (e.g. income, etc.).</p>\n\n\n\n<p>The first point to note is that most events denote the evolution of a latent situation: People grow unhappy in the period building up to a divorce, while they grow happy in the period building up to a marriage.</p>\n\n\n\n<p>The second point is that single life events do tend to affect happiness in the short run, but people often adapt to changes. Of course, there are clear differences in the extent to which people adapt. In the case of divorce, life satisfaction first drops, then goes up and stays high. For unemployment, there is a negative shock both in the short and long-run, notably among men. And for marriage, life satisfaction builds up before, and fades out after the wedding.</p>\n\n\n\n<p>In general, the evidence suggests that adaptation is an important feature of well-being. Many common but important life events have a modest long-term impact on self-reported happiness. Yet adaptation to some events, such as long-term unemployment, is neither perfect nor immediate.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Life-events-on-happiness.png\" alt=\"The effect of life events on life satisfaction\"/></figure>\n\n\n\n<h3>Does disability correlate with life satisfaction?</h3>\n\n\n\n<p>A number of papers have noted that long-term paraplegics do not report themselves as particularly unhappy, when compared to non-paraplegics (see for example the much-cited paper by Brickman, Coates, and Janoff-Bulman, 1978).{ref} Brickman, P., Coates, D., &amp; Janoff-Bulman, R. (1978). Lottery winners and accident victims: Is happiness relative?. Journal of personality and social psychology, 36(8), 917. Chicago.

It is, for example, considered in courts of law with respect to the compensation for disability.</p>\n\n\n\n<p>However, comparing differences in self-reported life satisfaction among people with different disability statuses is not an ideal source of evidence regarding the effect of tragedy on happiness. Non-paraplegics are potentially different to paraplegics in ways that are hard to measure. A better source of evidence are longitudinal surveys where people are tracked over time.</p>\n\n\n\n<p>Oswald and Powdthavee (2008){ref}Oswald, A. J., &amp; Powdthavee, N. (2008).

Here, \u2018seriously disabled\u2019 means that disability prevented them from being able to do day-to-day activities.</p>\n\n\n\n<p>As we can see\u2014and as the authors show more precisely through econometric techniques\u2014those entering disability suffer a sudden drop in life satisfaction, and recover only partially. This supports the idea that while adaptation plays a role for common life events, the notion of life satisfaction is indeed sensitive to tragic events.</p>\n\n\n\n<h6><a id=\"Life_satisfaction_of_those_entering_serious_disability_BHPS_19962002__Oswald_and_Powdthavee_2006_280\"></a>Life satisfaction of those entering serious disability, BHPS 1996-2002 \u2013 Oswald and Powdthavee (2006)</h6>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2017/04/Disability-and-happiness-Oswald-and-Powdthavee-2006.png\" alt=\"Life satisfaction of those entering serious disability\"/></figure>\n\n\n\n<h2>Life satisfaction and society</h2>\n\n\n\n<h3>Culture and life satisfaction</h3>\n\n\n\n<p>Comparisons of happiness among countries suggest that culture and history shared by people in a given society matter for self-reported life satisfaction. For example, as the chart here shows, culturally and historically similar Latin American countries have a higher subjective well-being than other countries with comparable levels of economic development. (This chart plots self-reported life satisfaction as measured in the 10-point Cantril ladder in the vertical axis, against GDP per capita in the horizontal axis).</p>\n\n\n\n<p>Latin America is not a special case in this respect. Ex-communist countries, for example, tend to have lower subjective well-being than other countries with comparable characteristics and levels of economic development.</p>\n\n\n\n<p>Academic studies in positive psychology discuss other patterns. Diener and Suh (2002) write: \u201cIn recent years cultural differences in subjective well-being have been explored, with a realization that there are profound differences in what makes people happy. Self-esteem, for example, is less strongly associated with life satisfaction, and extraversion is less strongly associated with pleasant affect in collectivist cultures than in individualist cultures\u201d.{ref}Diener, E., Oishi, S., &amp; Lucas, R. E. (2009). Subjective well-being: The science of happiness and life satisfaction. Oxford handbook of positive psychology, 2, 187-194.{/ref}</p>\n\n\n\n<p>To our knowledge, there are no rigorous studies exploring the causal mechanisms linking culture and happiness. However, it seems natural to expect that cultural factors shape the way people collectively understand happiness and the meaning of life.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2013/05/continent-version-GDP-pc-vs-Happiness-By-culture.png\" alt=\"Self-reported life satisfaction vs GDP per capita, in 2015\"/></figure>\n\n\n\n<h3>Sense of freedom and life satisfaction</h3>\n\n\n\n<p>A particular channel through which social environment may affect happiness is freedom: the society we live in may crucially affect the availability of options that we have to shape our own life.</p>\n\n\n\n<p>This visualization shows the relationship between self-reported sense of freedom and self-reported life satisfaction using data from the <a href=\"http://www.gallup.com/services/170945/world-poll.aspx\">Gallup World Poll</a>. The variable measuring life satisfaction corresponds to country-level averages of survey responses to the Cantril Ladder question (a 0-10 scale, where 10 is the highest level of life satisfaction); while the variable measuring freedom corresponds to the share of people who agree with the statement \u201cIn this country, I am satisfied with my freedom to choose what I do with my life\u201d.{ref}To be precise, the Gallup World Poll asks: \u201cIn this country, are you satisfied or dissatisfied with your freedom to choose what you do with your life?\u201d{/ref}</p>\n\n\n\n<p>As we can see, there is a clear positive relationship: countries where people feel free to choose and control their lives tend to be countries where people are happier. As Inglehart et al. (2008){ref}Inglehart, R., Foa, R., Peterson, C., &amp; Welzel, C. (2008). Development, freedom, and rising happiness: A global perspective (1981\u20132007). Perspectives on psychological science, 3(4), 264-285.{/ref} show, this positive relationship holds even after we control for other factors, such as incomes and strength of religiosity.</p>\n\n\n\n<p>Interestingly, this chart also shows that while there are some countries where the perceived sense of freedom is high but average life satisfaction is low (e.g. Rwanda); there are no countries where the perceived sense of freedom is low but average life satisfaction is high (i.e. there are no countries in the top left area of the chart).</p>\n\n\n\n<p>To our knowledge there are no rigorous studies exploring the causal mechanisms linking freedom and happiness. However, it seems natural to expect that self-determination and absence of coercion are important components of what people consider a happy and meaningful life.</p>\n\n\n\n<figure class=\"wp-block-image\"><img src=\"https://ourworldindata.org/app/uploads/2013/05/Happiness-vs-Freedom-in-Your-Life.png\" alt=\"Perception of freedom vs self-reported life satisfaction, 2016\"/></figure>\n\n\n\n<h3>The link between media and gloominess</h3>\n\n\n\n<p>A number of studies have found that there is a link between emotional exposure to negative content in news and changes in mood.</p>\n\n\n\n<p>Johnston and Davey (1997),{ref} Johnston, W. M., &amp; Davey, G. C. (1997). The psychological impact of negative TV news bulletins: The catastrophizing of personal worries. British Journal of Psychology, 88(1), 85-91.{/ref} for example, conducted an experiment in which they edited short TV news to display positive, neutral or negative material, and then showed them to three different groups of people. The authors found that people who watched the \u2018negative\u2019 clip were more likely to report a sad mood.</p>\n\n\n\n<p>This link between emotional content in news and changes in mood is all the more important if we consider that media gatekeepers tend to prefer negative to positive coverage of newsworthy facts (see, for example, Combs and Slovic 1979{ref} Combs, B., &amp; Slovic, P. (1979). Newspaper coverage of causes of death. Journalism Quarterly, 56(4), 837-849.{/ref}).</p>\n\n\n\n<p>Of course, mood is not the same as life satisfaction. Yet, as we discuss below in the <a href=\"https://ourworldindata.org/happiness-and-life-satisfaction/#data-quality-and-measurement\">section on measurement and data quality</a>, surveys measuring happiness often do capture emotional aspects of well-being. And in any case, people\u2019s perceptions of what it means to lead a meaningful life are heavily influenced by their expectations of what is possible and likely to occur with their lives; and this has also been shown to depend on media exposure.{ref}Riddle (2010), for example, found that people watching more vivid violent media gave higher estimates of the prevalence of crime in the real world. (Riddle, 2010, \u201cAlways on my mind: Exploring how frequent, recent, and vivid television portrayals are used in the formation of social reality judgments.\u201d Media Psychology.) {/ref}</p>\n\n\n\n<h2>Data Quality and Measurement</h2>\n\n\n\n<h3>Can \u2018happiness\u2019 really be measured?</h3>\n\n\n\n<p>The most natural way to attempt to measure subjective well-being is to ask people what they think and feel. Indeed, this is the most common approach.</p>\n\n\n\n<p>In practice, social scientists tend to rely on questions inquiring directly about happiness, or on questions inquiring about life satisfaction. The former tend to measure the experiential or emotional aspects of well-being (e.g. \u201cI feel very happy\u201d), while the latter tend to measure the evaluative or cognitive aspects of well-being (e.g. \u201cI think I lead a very positive life\u201d).</p>\n\n\n\n<p>Self-reports about happiness and life satisfaction are known to correlate with things that people typically associate with contentment, such as cheerfulness and smiling. (In <a href=\"https://ourworldindata.org/app/uploads/2017/04/Life-Satisfaction-vs-Laugh-Gallup.png\">this scatter plot</a> you can see that countries where people have higher self-reported life satisfaction are also countries where people tend to smile more).</p>\n\n\n\n<p>Experimental psychologists have also shown that self reports of well-being from surveys turn out to correlate with activity in the parts of the brain associated with pleasure and satisfaction. And various surveys have confirmed that people who say they are happy also tend to sleep better and express positive emotions verbally more frequently.</p>\n\n\n\n<p>The following table, adapted from Kahneman and Krueger (2006){ref}Kahneman, D., &amp; Krueger, A. B. (2006). Developments in the measurement of subjective well-being. The journal of economic perspectives, 20(1), 3-24.{/ref}, provides a list of the variables that researchers have found to be related to self-reported happiness and life satisfaction.</p>\n\n\n\n<p>The main conclusion from the evidence is that survey-based measures of happiness and life satisfaction do provide a reasonably consistent and reliable picture of subjective well-being.</p>\n\n\n\n<table id=\"tablepress-65\" class=\"tablepress tablepress-id-65\">\n<thead>\n<tr class=\"row-1\">\n\t<th class=\"column-1\"><div style=\"float: left;\"> Correlates of high life satisfaction and happiness</div></th>\n</tr>\n</thead>\n<tbody>\n<tr class=\"row-2\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Smiling frequency</div></td>\n</tr>\n<tr class=\"row-3\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Smiling with the eyes (\"unfakeable smile\") </div></td>\n</tr>\n<tr class=\"row-4\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Ratings of one's happiness made by friends</div></td>\n</tr>\n<tr class=\"row-5\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Frequent verbal expressions of positive emotions </div></td>\n</tr>\n<tr class=\"row-6\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Sociability and extraversion</div></td>\n</tr>\n<tr class=\"row-7\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Sleep quality </div></td>\n</tr>\n<tr class=\"row-8\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Happiness of close relatives </div></td>\n</tr>\n<tr class=\"row-9\">\n\t<td class=\"column-1\"><div style=\"float: left;\">Self-reported health </div></td>\n</tr>\n<tr class=\"row-10\">\n\t<td class=\"column-1\"><div style=\"float: left;\"> High income, and high income rank in a reference group </div></td>\n</tr>\n<tr class=\"row-11\">\n\t<td class=\"column-1\"><div style=\"float: left;\"> Active involvement in religion</div></td>\n</tr>\n<tr class=\"row-12\">\n\t<td class=\"column-1\"><div style=\"float: left;\"> Recent positive changes of circumstances (increased income, marriage) </div></td>\n</tr>\n</tbody>\n</table>\n\n\n\n\n<h3>Is \u2018life satisfaction\u2019 the same as \u2018happiness\u2019?</h3>\n\n\n\n<p>In this entry we discuss data and empirical research on happiness and life satisfaction. However, it is important to bear in mind that \u201clife satisfaction\u201d and \u201chappiness\u201d are not really synonyms. And this is of course reflected in the data, since self-reported measures of these two variables come from asking different kinds of questions.</p>\n\n\n\n<p>The World Value Survey asks directly about happiness: <em>\u201cTaking all things together, would you say you are (i) Very happy, (ii) Rather happy, (iii) Not very happy, (iv) Not at all happy, (v) Don\u2019t know.\u201d</em></p>\n\n\n\n<p>The Gallup World Poll, on the other hand, uses the Cantril Ladder question and asks respondents to evaluate their life: <em>\u201cPlease imagine a ladder, with steps numbered from 0 at the bottom to 10 at the top. The top of the ladder represents the best possible life for you and the bottom of the ladder represents the worst possible life for you. On which step of the ladder would you say you personally feel you stand at this time?\u201d</em></p>\n\n\n\n<p>As the following scatter plot shows, these two measures are clearly closely related (countries that score high in one measure also tend to score high in the other), yet they are not identical (there is substantial dispersion, with many countries sharing the same score in one variable but diverging in the other).</p>\n\n\n\n<p>The differences in responses to questions inquiring about life satisfaction and happiness are consistent with the idea that subjective well-being has two sides: an experiential or emotional side, and an evaluative or cognitive side. Of course, the limits between emotional and cognitive aspects of well-being are blurred in our minds; so in practice both kinds of questions measure both aspects to some degree. Indeed, social scientists often construct \u2018subjective well-being indexes\u2019 where they simply average out results from various types of questions.</p>\n\n\n\n<iframe loading=\"lazy\" src=\"https://ourworldindata.org/grapher/Happiness-WVS-vs-Gallup\" width=\"\u201c300\u201d\" height=\"\u201c150\u201d\"></iframe>\n\n\n\n<h3>Are happiness averages really meaningful?</h3>\n\n\n\n<p>The most common way to analyze data on happiness consists in taking averages across groups of people. Indeed, cross-country comparisons of self-reported life satisfaction, such as those presented in \u2018happiness rankings\u2019, rely on national averages of reports on a scale from 0 to 10 (the Cantril Ladder).</p>\n\n\n\n<p>Is it reasonable to take averages of life satisfaction scores? Or, in more technical terms: are self reports of Cantril scores really a cardinal measure of well-being?</p>\n\n\n\n<p>The evidence tells us that survey-based reports on the Cantril Ladder do allow cardinal measurement reasonably well\u2014respondents have been found to translate verbal labels, such as \u2018very good\u2019 and \u2018very bad\u2019, into roughly the same numerical values.{ref}Ferrer\u2010i\u2010Carbonell, A., &amp; Frijters, P. (2004). How important is methodology for the estimates of the determinants of happiness?. The Economic Journal, 114(497), 641-659.{/ref} {ref}Van Praag, B.M.S. (1991). \u2018Ordinal and cardinal utility: an integration of the two dimensions of the welfare concept\u2019, Journal of Econometrics, vol. 50, pp. 69\u201389.{/ref}</p>\n\n\n\n<p>But as with any other aggregate indicator of social progress, averages need to be interpreted carefully, even if they make sense arithmetically. For example, if we look at happiness by age in a given country, we may see that older people do not appear to be happier than younger people. Yet this may be because the average-by-age figure from the snapshot confounds two factors: the age effect (people from the same cohort do get happier as they grow older, across all cohorts) and the cohort effect (across all ages, earlier generations are less happy than more recent generations). If the cohort effect is very strong, the snapshot can even give a picture that suggests people become <em>less</em> happy as they grow older, even though the exact opposite is actually true within all generations.</p>\n\n\n\n<p>This example is in fact taken from the real world: using data from the US, Sutin et al. (2013){ref}Sutin, A. R., Terracciano, A., Milaneschi, Y., An, Y., Ferrucci, L., &amp; Zonderman, A. B. (2013). The effect of birth cohort on well-being The legacy of economic hard times. Psychological science, 0956797612459658.{/ref} showed that self-reported feelings of well-being tend to increase with age across generations, but overall levels of well-being depend on when people were born.</p>\n\n\n\n<h4>How much does language matter for cross-country comparisons of happiness?</h4>\n\n\n\n<p>Linguistic differences are often seen as a major obstacle for making cross-country comparisons of happiness. However, there is evidence suggesting that comparability issues, at least in respect to language, are less problematic than many people think.</p>\n\n\n\n<p>Studies have shown, for example, that in interviews in which respondents are shown pictures or videos of other individuals, respondents can broadly identify whether the individual shown to them was happy or sad; and this is also true when respondents were asked to predict the evaluations of individuals from other cultural communities. (For evidence of this see Sandvik et al., 1993; Diener and Lucas, 1999).{ref}Sandvik, E., Diener, E. and Seidlitz, L. (1993). \u2018Subjective well-being: the convergence and stability of self and non self report measures\u2019, Journal of Personality, vol. 61, pp. 317\u201342. Diener, E. and Lucas, R.E. (1999). \u2018Personality and subjective well-being\u2019, in Kahneman et al. (1999) chapter 11.{/ref}</p>\n\n\n\n<p>Studies have also shown that \u2018indigenous emotions\u2019 across cultures (i.e. feelings that are unique in that they do not have equivalents in the English language) are not experienced any more frequently or differently than common translated emotions. (See Scollon et al. 2005).{ref}Scollon, C. N., Diener, E., Oishi, S., &amp; Biswas-Diener, R. (2004). Emotions across cultures and methods. Journal of cross-cultural psychology, 35(3), 304-326.{/ref}</p>\n\n\n\n<p>The conclusion, therefore, seems to be that there is some basic understanding among humans about what it means to be \u2018happy\u2019. Survey-based measures of self-reported life satisfaction are informative about cross-country differences, even if these comparisons are obviously noisy.</p>\n\n\n\n<h2>Data Sources</h2>\n\n\n\n<h4>Cross-country estimates</h4>\n\n\n\n<h4><a id=\"World_Happiness_Report_379\"></a>World Happiness Report</h4>\n\n\n\n<ul><li><strong>Data:</strong> Country averages of self-reported life satisfaction (Question: Cantril Ladder).</li><li><strong>Underlying source:</strong> Gallup World Poll</li><li><strong>Time span:</strong> 2005-2022</li><li><strong>Available at:</strong> <a href=\"http://worldhappiness.report/\">World Happiness Report</a></li></ul>\n\n\n\n<h4><a id=\"European_Commission__Eurobarometer_Interactive_386\"></a>European Commission \u2013 Eurobarometer Interactive</h4>\n\n\n\n<ul><li><strong>Data:</strong> Life satisfaction (Question: <em>\u201cOn the whole are you very satisfied, fairly satisfied, not very satisfied or not at all satisfied with the life you lead ?\u201d</em>)</li><li><strong>Geographical coverage:</strong> EU countries</li><li><strong>Time span:</strong> 1973 &#8211; 2015</li><li><strong>Available at:</strong> <a href=\"http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index\">http://ec.europa.eu/commfrontoffice/publicopinion/index.cfm/Chart/index</a></li></ul>\n\n\n\n<hr class=\"wp-block-separator\"/>\n\n\n\n<h4><a id=\"The_World_Value_Survey_WVS_395\"></a>The World Value Survey (WVS)</h4>\n\n\n\n<ul><li><strong>Data:</strong> Happiness and life satisfaction, as well as many other social and cultural characteristics from cross-national time-series surveys.
