Data from this early period shows that government funds to finance the expansion of education came from a number of different sources, but specifically taxes at the local level played a crucial role. The historical role of local funding for public schools is important to help us understand changes – or persistence– in regional inequalities.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The second half of the 20th century marked the beginning of education expansion as a global phenomenon.

Yet behind these broad global trends there is substantial cross-country – and cross-regional – heterogeneity. In high-income countries, for instance, households shoulder a larger share of education expenditures at higher education levels than at lower levels – but in low-income countries this is not the case. Malawi is a stark example: tertiary education is almost completely subsidised by the state, yet household contribute almost 20% of the costs of primary education.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Following the agreement of the Millennium Development Goals, the first decade of the 21st century saw an important increase in international financial flows under the umbrella of development assistance. Recent estimates show that development assistance for education has stopped growing since 2010, with notable aggregate reductions on flows going to primary education. These changes in the priorization of development assistance for education across levels and regions, can have potentially large distributional effects, particularly within low income countries that depend substantially on this source of funding for basic education.{ref}As per estimates reported in Steer L. and K.

This is indicative of a complex 'education production function' whereby for any given level of expenditure, output achieved depends crucially on the input mix.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Available evidence specifically on the importance of school inputs to produce education, suggests that learning outcomes may be more sensitive to improvements in the quality of teachers, than to improvements in class sizes. Regarding household inputs, the recent experimental evidence suggests that interventions that increase the benefits of attending school (e.g. conditional cash transfers) are particularly likely to increase student time in school; and that those that incentivise academic effort (e.g. scholarships) are likely to improve learning outcomes.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Policy experiments have also shown that pre-school investment in demand-side inputs leads to large positive impacts on education – and other important outcomes later in life.

This is a recent social achievement. The advancement of the idea to provide education for more and more children only began in the mid 19th century, when most of today’s industrialized countries started expanding primary education. The following visualization, plotting public expenditure on education as a share of <a href="https://ourworldindata.org/gdp-data/">Gross Domestic Product </a>(GDP) for a number of early-industrialized countries, shows that this expansion took place mainly through public funding.{ref}The source for the visualization below – Tanzi & Schuktnecht (2000) – compiles estimates from many sources, including: League of Nations Statistical Yearbook (various years), Mitchell (1962), OECD Education at a Glance (1996), UNESCO World Education Report (1993), UNDP Human Development Report (1996), UN World Economics Survey (various years). To the extent that the authors do not specify which sources were prioritised for each year/country, it is not possible for us to reliably extend the time series with newer data. For instance, the OECD Education at a Glance report (1998), which presents estimates for the years 1990 and 1995, suggests discrepancies with the values reported by Tanzi & Schuktnecht (2000) for 1993.{/ref} Our entry on <a href="https://ourworldindata.org/primary-education-and-schools/">Primary Education and Schools</a> provides details regarding how this expansion in funding materialized in better education outcomes for these countries.</p> <!-- /wp:paragraph --> <!-- wp:html --> <figure><iframe style="width: 100%; height: 600px; border: 0px none;" src="https://ourworldindata.org/grapher/total-government-expenditure-on-education-gdp?tab=chart" width="300" height="150"></iframe></figure> <!-- /wp:html --> <!-- wp:heading {"level":4} --> <h4>How did the US finance the expansion of public education?</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>Public schools in the US currently educate more than 90% of all children enrolled in elementary and secondary schools.{ref}As per <a href="https://nces.ed.gov/programs/digest/d15/tables/dt15_105.20.asp">2015 enrolment estimates from the NCES.</a>{/ref}</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>This is the result of a process of education expansion that relied heavily on public funding, particularly from local governments. The visualization shows the sources of revenues for public schools in the US over the last 120 years. As it can be seen, states and localities are – and have always been – the main sources of funding for public primary education in the US. In fact, we observe three broad periods in this graph: there is first a period of stable revenues until 1920, then a period of sharp growth and decline during the interwar years, and then a period of substantial growth since the second world war, slowing down in the 1970s. In all these periods, federal funding was always very small, as can be seen when changing the visualisation from 'absolute' to 'relative'. Disaggregated data from the last couple of decades gives further insights into the specific sources of local revenues for schools in the US: the largest part comes from property taxes (about 80% of local revenues came from property taxes in 2013), while only a very small part comes from fees and donations (private funding for public schools, which is considered a local revenue, amounted to less than 2% of total public school revenues in 2013). This heavily decentralised system relying on property taxes has the potential of creating large inequalities in education, since public schools in affluent urban areas are able to raise more funding from local revenues. Indeed, a significant part of the debate on education inequalities in the US today focuses on the importance of increasing progressive federal spending to reduce inequalities in public school funding.{ref}A <a href="http://www.huffingtonpost.com/2015/03/13/arne-duncan-school-funding-disparities_n_6864866.html">recent article from the Huffington Post</a> highlights this point, including interesting visualizations documenting the important role that federal funding plays in reducing expenditure inequalities.{/ref}</p> <!-- /wp:paragraph --> <!-- wp:html --> <figure><iframe style="width: 100%; height: 600px; border: 0px none;" src="https://ourworldindata.org/grapher/revenues-for-public-schools-by-source-us" width="300" height="150"></iframe></figure> <!-- /wp:html --> <!-- wp:heading {"level":4} --> <h4>How did France finance the expansion of public education?</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>The case of the US above shows that funding for public schools has been historically a responsibility of local governments. In other countries, such as France, the expansion of public education also took place initially with resources from local governments, but relatively quickly the fiscal burden was shifted to the national level. In France this transition was associated with a sharp jump towards universal access and a concomitant reduction in regional inequalities. The following visualization from Lindert (2004){ref}Lindert, Peter H. <em>Growing public: Volume 1, the story: Social spending and economic growth since the eighteenth century</em>. Vol. 1. Cambridge University Press, 2004.{/ref} provides evidence of the French experience. As we can see there are three distinct periods: education spending was initially low and mainly private, then in 1833 funding began growing with local resources after the introduction of a law liberating communes to raise more local taxes for schools, and finally in 1881 the national government took over most of the financial responsibility after the introduction of a new law that abolished all fees and tuition charges in public elementary schools. In the source book, Lindert (2004) provides further evidence of how this transition towards centrally funded public education reduced north-south inequalities in France.</p> <!-- /wp:paragraph --> <!-- wp:heading {"level":6} --> <h6>Sources of funds for France’s public primary schools, 1820–1913 – Figure 5.5 in Lindert (2004){ref}Lindert, Peter H. <em>Growing public: Volume 1, the story: Social spending and economic growth since the eighteenth century</em>.

The following graph does this using data from the National Center for Education Statistics in the US.

The visualization, using data from Szirmai (2005){ref} Szirmai, A. (2005) The Dynamics of Socio-Economic Development: An Introduction. Cambridge University Press. {/ref}, shows government expenditure on education as a share of national income for a selection of low and middle-income countries, together with the corresponding average for high-income countries, for the period 1960-2010. As it can be seen, by 1990 government spending on education in many developing countries was already close to the average observed in developed countries.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>It is important to point out that the remark above makes reference to convergence in expenditure relative to <em>income</em>. To the extent that low-income countries remain poorer than high-income countries, gaps in levels of expenditure per pupil are persistently large. Indeed, cross-country heterogeneity in education expenditure per pupil is currently much higher than heterogeneity in expenditure as share of GDP.{ref}In 2010, high income countries spent 6721 US PPP dollars per primary school pupil. Low income countries, in contrast, spent 115 US PPP dollars per pupil (UNESCO EFA Global Monitoring Report 2014). {/ref} One factor contributing to the slower convergence of expenditure per pupil in real terms is the fact that teachers' salaries – <a href="https://ourworldindata.org/financing-education#where-does-funding-for-education-go-to">the main component of education expenditure</a> – are much higher in high-income countries, because labour has a higher opportunity cost in these countries. In general, the opportunity cost of labour is a key variable that governments in developing countries should factor in when deciding whether to expand education now, rather than later.</p> <!-- /wp:paragraph --> <!-- wp:html --> <figure><iframe style="width: 100%; height: 600px; border: 0px none;" src="https://ourworldindata.org/grapher/share-of-education-in-government-expenditure" width="300" height="150"></iframe></figure> <!-- /wp:html --> <!-- wp:heading {"level":4} --> <h4>Education inequality is falling around the world</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>An important consequence of the global education expansion is a reduction in education inequality across the globe. The following visualization shows this through a series of graphs plotting changes in the Gini coefficient of the distribution of years of schooling across different world regions. The Gini coefficient is a measure of inequality and higher values indicate higher inequality – you can read about the definition and estimation of Gini coefficients in our entry on <a href="https://ourworldindata.org/income-inequality/#the-gini-coefficient">income inequality</a>. The time-series chart shows inequality by age group. It can be seen that as inequality is falling over time, the level of inequality is higher for older generations than it is for younger generations. We can also see that in the reference period education inequality went down every year, for all age groups and in all world regions.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Have gains from historical education expansion fully materialized? The breakdown by age gives us a view into the future: as the inequality is lower among today's younger generations, we can expect the decline of inequality to continue in the future. Thus, further reductions in education inequality are still to be expected within developing countries; and if the expansion of global education can be continued, we can speed up this important process of global convergence.</p> <!-- /wp:paragraph --> <!-- wp:heading {"level":6} --> <h6>Education Gini coefficients by world region for selected age groups, 1960- 2010 – Figure 4 in Crespo Cuaresma et al.

The following visualization show two graphs comparing the concentration of years of education in South Korean between the years 1970 and 2010. To be precise, each of these graphs shows an education Lorenz curve: a plot showing the cumulative percentage of the schooling years across all levels of education on the vertical axis, and the cumulative percentage of the population on the horizontal axis. As it can be seen, in 2010 education was much less concentrated than in 1970, not only because there was a smaller share of individuals without schooling (shown along the bottom of the chart), but also because there was a smaller share of individuals concentrating large proportions of school-years at higher levels of education. Indeed, in only 40 years South Korea was able to double the mean years of schooling (from 6 to 12 years) and at the same time get remarkably close to the 45-degree line marking the hypothetical scenario of perfect equality of schooling. In other entries we show that in this same period South Korea increased drastically its <a href="https://ourworldindata.org/gdp-growth-over-the-last-centuries/#real-gdp-per-capita-around-the-world-ppp-adjusted-since-1000-max-roserref"> GDP per capita</a> while significantly improving health outcomes, such as <a href="https://ourworldindata.org/grapher/child-mortality?country=KOR">child mortality</a>.</p> <!-- /wp:paragraph --> <!-- wp:heading {"level":6} --> <h6>Inequality of Educational Attainment in South Korea 1970 and 2010{ref}Data from Petra Sauer (2016) – The Role of Age and Gender in Education Expansion.

For instance, of the 36 countries with available data for 2000 to 2010, only around half increased spending on education relative to the other sectors. The data does suggest, however, that there is large and persistent cross-country heterogeneity in the relative importance of education vis-a-vis other sectors, even within developing countries.

The top chart in this figure, corresponding to high income countries, shows a very clear pattern: households contribute the largest share of expenses in tertiary education, and the smallest share in primary education. Roughly speaking, this pattern tends to be progressive, since students from wealthier households are more likely to attend tertiary education, and those individuals who attend tertiary education are likely to perceive large private benefits (more on this in our entry on <a href="https://ourworldindata.org/skill-premium-income-by-education/">Skill Premium</a>).{ref}Strictly speaking, for this spending pattern to be truly progressive there must be subsidies or income-contingent loans to guarantee that low-income students can also access tertiary education and reap the private benefits from this type of investment.{/ref} In contrast, the bottom chart shows a very different picture: in several low-income countries households contribute proportionally more to primary education than to higher levels.

Today, public resources still dominate funding for the primary, secondary and post-secondary non-tertiary education levels in these countries. While in the last decade the share of public funding for these levels of education has decreased slightly, the broad pattern is remarkably stable. The visualization presents OECD-average expenditure on education institutions by source of funds.{ref}The OECD provides country-specific figures. However, there is relatively little variation across OECD countries in this respect. This is explained by near-universal enrolment rates at these levels of education and the demographic structure of the population.{/ref} By clicking on the option labeled 'relative' you can see the corresponding share of each source: private funding went up from 7.9% in 2000, to 9.4% in 2012.

In fact, the OECD reports that in Europe the concept of universal access to education for 3-6 year-olds is generally accepted: most countries in this region provide all children with at least two years of free, publicly funded pre-primary education in schools before they begin primary education.</p> <!-- /wp:paragraph --> <!-- wp:heading {"level":6} --> <h6>Expenditure on pre-primary educational institutions (% of GDP), OECD, 2012 – Figure C2.4 in <a href="http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1">Education at a Glance (2015)</a></h6> <!-- /wp:heading --> <!-- wp:image {"align":"center","id":8074,"linkDestination":"custom"} --> <div class="wp-block-image"><figure class="aligncenter"><a href="https://ourworldindata.org/app/uploads/2016/06/OECD_Expenditure_Pre-primary.png"><img src="https://ourworldindata.org/app/uploads/2016/06/OECD_Expenditure_Pre-primary-750x301.png" alt="OECD_Expenditure_Pre-primary" class="wp-image-8074"/></a></figure></div> <!-- /wp:image --> <!-- wp:heading {"level":4} --> <h4>Where does funding for education go to?</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>The largest part of funding devoted to education in OECD countries goes to finance current expenditures, mainly compensation of staff – specifically, teachers.

The following table provides further details regarding the type of expenditures that comprise current spending. Specifically, this chart shows a breakdown of expenditure for tertiary-level institutions in the US (public and private), during the period 1980-1997. It shows that instruction accounts for almost half of expenditure; and while there are some small differences across sectors, there is a fair amount of stability in expenditures across time. This serves as a benchmark for lower education levels, where instruction takes an even larger share of expenditure.{ref}This is a stylized fact of OECD education spending. In all the OECD countries, the share of spending devoted to compensation of teachers is by far the largest component of current expenditure. Moreover, expenditure on teachers' compensation is larger at the combined primary, secondary and post-secondary non-tertiary levels of education than at the tertiary level.

As it can be seen, there are two distinct periods: in 2003-2010 flows for education increased substantially, more than doubling in real terms across all levels of education; and in the years 2010-2013 funding for basic education <em>decreased</em>, while funding for secondary and post-secondary education remained relatively constant. For many low income countries, where development assistance contributes a substantial share of funding for education, this marked change in trends is important. As a reference, in 2012 development assistance accounted for more than 20 percent of all domestic spending on basic education in recipient low-income countries.{ref}Steer L. and K.

Specifically, the share of development assistance for primary education going to sub-Saharan Africa has been decreasing sharply since the agreement of the Millennium Development Goals. The following chart shows this: sub-Saharan Africa’s share in total aid to primary education declined from 52 percent in 2002 to 30 percent in 2013, while the continent’s share in the total number of out-of-school children rose from 46 percent to 57 percent. This pattern is something specific to the education sector within the broader development assistance landscape: in the healthcare sector the overall slowdown of flows started a couple of years later, was less abrupt, and affected proportionally less the sub-Saharan countries.{ref}The share of development assistance going to sub-Saharan Africa has decreased as a whole – from 55 percent in 2002 to 40 percent in 2013 –, but as we note the drop specifically for primary education has been steeper.{/ref} Indeed, recent studies further highlight that development assistance for education is significantly different to assistance for healthcare in other ways: the education sector attracts less earmarked funding through multilaterals, and includes a smaller proportion of resources that developing governments can directly control for programming.{ref}Steer L. and K.

But for any given country, with a determined income distribution and demographic structure, the extent to which public spending on education contributes to reduce inequality depends crucially on the way in which spending is focused across education levels. The recent UNICEF report <a href="http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf">The Investment Case for Education and Equity</a> shows that in low income countries, on average 46 percent of public resources are allocated to the 10 percent of students who are most educated – while this figure goes down to 26 and 13 percent in lower-middle and upper-middle income countries respectively. The following visualization shows further details on the concentration of public spending across different countries. The vertical axis shows the percentage of public education resources going to the 10% most educated or 10% least educated students – as we can see expenditure is heavily concentrated at the top in many low income countries.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>The earlier remarks about trends in international education financing flows (namely that aid is very important in low-income countries, and that a relatively low and shrinking share of aid is going to primary levels), suggest that inequality in public spending will worsen in low income countries. Yet development assistance priorities have a scope for changing this.{ref}The conclusion from these figures is that, while public spending does reduce education inequality in low income countries, remaining inequalities could be further reduced by shifting resources towards lower levels of education. This evidently does not mean that resources <em>should</em> be shifted – low income countries and aid donors may have other objectives apart from reducing inequality. But the case for reducing inequality at the bottom is very strong, and some studies suggest that returns to education at the primary level might be higher than at post-primary levels in low income countries (for a discussion of the vast literature on returns to education, and the ongoing debate on the validity of estimates, see Heckman, J.

The logic is that individuals may not spend enough on education because they fail to internalize the positive effect that their education has on other people. But there are, of course, also equity arguments to justify government intervention in the provision of education – for instance, reducing inequality in education may be of intrinsic value, or may be instrumental in reducing inequalities in other outcomes.{/ref} This essentially means that investing in education yields both private and social returns. Private returns to education include higher wages and better employment prospects. Social return include pro-social behaviour (e.g. volunteering, political participation) and interpersonal <a href="https://ourworldindata.org/trust/">trust</a>. The following chart uses OECD results from the Survey of Adult Skills to show how self-reported trust in others correlates with educational attainment. More precisely, this chart plots the percentage-point difference in the likelihood of reporting to trust others, by education level of respondents. Those individuals with upper secondary or post-secondary non-tertiary education are taken as the reference group, so the percentage point difference is expressed in relation to this group. As we can see, in all countries those individuals with tertiary education were by far the group most likely to report trusting others. And in almost every country, those with post-secondary non-tertiary education were more likely to trust others than those with primary or lower secondary education.

In this table, the left-hand side summarizes results from econometric studies focusing on developing countries, while the right-hand side presents evidence from the US (where studies have concentrated extensively). We can see that for all listed inputs and across all countries, the share of studies that have found a positive effect is small – in fact, the majority of studies find either no effect, or a negative effect. This clearly does not mean that these classroom resources are not important, but rather that it is very difficult to know with confidence when and where they are a binding constraint to improve learning outcomes. A first conclusion, therefore, seems to be that context and input mix are fundamental to improving outcomes – even in developing countries where the expected returns to additional resources is large across the board.</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>Taking the ratio of positive to negative effects detected in the literature as a proxy for what tends to work best, we can derive a second conclusion from the table: spending more resources on better teachers (i.e. improving teacher experience and teacher education) tends to work better to improve learning outcomes than simply increasing the number of teachers per pupil. And this seems to be true both in developed and developing countries. This last conclusion is consistent with the main message from the OECD's report <a href="http://www.oecd.org/pisa/pisaproducts/pisainfocus/49685503.pdf">Does money buy strong performance in PISA?</a>, which points out that countries that prioritised the quality of teachers over class sizes performed better in PISA tests.{ref} This claim is clearly only descriptive, since there are many underlying variables that simultaneously drive teacher characteristics and student outcomes in any particular country. Indeed, most of the available evidence on whether teacher quality and quantity matters is difficult to interpret causally, as it is hard to find instances where teacher quality / quantity varies exogenously. A recent study concludes on the topic: <em> "teachers vary in many ways, but we found no high-quality studies that have examined the impact of teacher characteristics on student learning or time in school" </em>(source: page 696, Glewwe, P. and Muralidharan, K.

And we have also pointed out that improving teacher quality may be a particularly good instrument to improve teaching outcomes. This leads to a natural question: are pay-for-performance teacher contracts an effective instrument to improve learning outcomes? A growing body of literature in the economics of education has started using randomized control trials (i.e. policy 'experiments') to answer this question. Glewwe and Muralidharan (2016){ref}Glewwe, P. and Muralidharan, K.

In simple words, it is possible that pay-for-performance yields 'teaching to the test'. Alternative incentive mechanisms, such as community-based monitoring of teachers, have been proposed as an alternative. Glewwe and Muralidharan (2016) also provide a review of the – somewhat limited – available evidence on such alternative incentive mechanisms.{ref}They conclude that "evidence on the impact of monitoring on time in school is scarce and not encouraging...[while] the evidence of the impact of monitoring on student learning is only somewhat more encouraging"{/ref}</p> <!-- /wp:paragraph --> <!-- wp:heading {"level":3} --> <h3>Household inputs</h3> <!-- /wp:heading --> <!-- wp:heading {"level":4} --> <h4>School attendance and student effort are responsive to incentives</h4> <!-- /wp:heading --> <!-- wp:paragraph --> <p>Demand-side inputs are as important as supply-side inputs to produce education. Attending school and exerting effort are perhaps the most obvious examples: without these inputs even the best endowed schools will fail to deliver good outcomes. The table summarizes information on different demand-side investments that have shown to successfully improve quality and quantity outcomes. More precisely, this table gathers evidence from randomized control trials in developing countries, as per the review in Glewwe and Muralidharan (2016). The reported figures correspond to positive/negative significant/insignificant estimates across a set of available experimental studies (bear in mind some studies estimate more than one effect – e.g. by measuring outcomes at several points in time). As we can see, the evidence suggests interventions that increase the benefits of attending school – such as conditional cash transfers – are likely to increase student time in school. And those that increase the benefits of higher effort and better academic performance – such as merit scholarships – are likely to improve learning outcomes (see Glewwe and Muralidharan 2016 for further details on the underlying policy interventions, plus further evidence and discussion of results).</p> <!-- /wp:paragraph --> <!-- wp:heading {"level":6} --> <h6>Summary of impacts for selected demand-side interventions on education outcomes in developing countries – based on Tables 4 and 5 from Glewwe and Muralidharan (2016){ref}Glewwe, P. and Muralidharan, K.

The following visualization presents a comparison of the impact that a number of different health interventions have achieved in different countries – together with some non-health-related interventions that serve as reference. The height of each bar in this graph reflects the additional school years achieved per hundred dollars spent on the corresponding intervention; so these estimates can be interpreted as a measure of how cost-effective the different interventions are.{ref}Bear in mind that the reported gains in school years are a measure of the <em>total</em> impact of the program across the treated population, rather than impact per treated student. Further information on cost-effectiveness analysis is available from the source of the graph.{/ref}</p> <!-- /wp:paragraph --> <!-- wp:paragraph --> <p>We see that treating children for intestinal worms (labeled 'deworming' in the chart) led to an additional 13.9 years of education for every $100 spent in Kenya; while a program targeting anaemia (labeled 'iron fortification') led to 2.7 additional years per $100 in India. These interventions seem to be much more cost-effective to improve test scores than conditional cash transfers, free school uniforms, or merit scholarships (further details on all interventions available from Dhaliwal et al. 2012{ref}Dhaliwal, I., Duflo, E., Glennerster, R., & Tulloch, C.

Of course, ranking these interventions is not trivial since most programmes achieve multiple outcomes – indeed, we have already discussed that remedial teaching is generally effective to increase test-scores, although here we see a particular instance where it had no impact on school attendance. Nevertheless, health interventions seem to be particularly interesting, since they lead to substantial achievements in both education <em>and</em> health outcomes (for a recent analysis of the literature on the impacts of mass deworming see Croke et al. 2016{ref}Croke, Kevin, Joan Hamory Hicks, Eric Hsu, Michel Kremer, and Edward Miguel. 2016. “<a href="http://scholar.harvard.edu/files/kremer/files/deworming-nber_2016-06-30.pdf">Does Mass Deworming Affect Child Nutrition?

To a great extent, this is what drives large and remarkably persistent gaps in the education achievement between individuals in the same country, but in different socioeconomic environments. Cunha et al. (2006) provide a detailed account of the theory and evidence behind this claim, and discuss its implications for the design of education policies. In the chart we see the impacts from the Perry Preschool Program – a flagship experimental intervention study, designed to test the impact of pre-school education on subsequent education outcomes.{ref}More specifically, the Perry pre-school 'experiment' consisted in enrolling 65 randomly selected black children in a pre-school program, and comparing their outcomes later in life against those achieved by a control group of roughly the same size. The treatment consisted of a daily 2.5-hour classroom session on weekday mornings and a weekly 90-minute home visit by the teacher on weekday afternoons to involve the mother in the child's educational process. More information and details on the intervention are available in Cunha et al. (2006).{/ref} The chart shows disadvantaged children participating in the pre-school program (the 'treatment group') had higher grades and were more likely to graduate from high school than the reference control group. Moreover, they spent substantially less time in special education.

In most countries basic education is nowadays perceived not only as a right, but also as a duty – governments are typically expected to ensure access to basic education, while citizens are often required by law to attain education up to a certain basic level.{ref} See the Wikipedia entry on [compulsory education](https://en.wikipedia.org/wiki/Compulsory_education) for a table of the ages of compulsory schooling around the world.{/ref} This was not always the case: the advancement of these ideas began in the mid 19th century, when most of today’s industrialized countries started expanding primary education, mainly through public finances and government intervention. Data from this early period shows that government funds to finance the expansion of education came from a number of different sources, but specifically taxes at the local level played a crucial role. The historical role of local funding for public schools is important to help us understand changes – or persistence– in regional inequalities. The second half of the 20th century marked the beginning of education expansion as a global phenomenon. Available data shows that by 1990 government spending on education as a share of national income in many developing countries was already close to the average observed in developed countries.{ref}As per estimates from Adam Szirmai, (2015) The Dynamics of Socio-Economic Development, [www.dynamicsofdevelopment.com](https://web.archive.org/web/20191223132520/http://www.dynamicsofdevelopment.com:80/){/ref} This global education expansion in the 20th century resulted in a historical reduction in education inequality across the globe: in the period 1960-2010 education inequality went down every year, for all age groups and in all world regions. Recent estimates of education inequality across age groups suggest that further reductions in schooling inequality are still to be expected within developing countries.{ref}As per estimates of Gini coefficients for the distribution of school years in Crespo Cuaresma, J., KC, S., & Sauer, P. (2013). Age-specific education inequality, education mobility and income growth (No. 6). WWWforEurope. Available online from [www.ecineq.org](http://www.ecineq.org/ecineq_bari13/FILESxBari13/CR2/p100.pdf){/ref} Recent cross-country data from UNESCO tells us that the world is expanding government funding for education today, and these additional public funds for education are not necessarily at the expense of other government sectors. Yet behind these broad global trends there is substantial cross-country – and cross-regional – heterogeneity. In high-income countries, for instance, households shoulder a larger share of education expenditures at higher education levels than at lower levels – but in low-income countries this is not the case. Malawi is a stark example: tertiary education is almost completely subsidised by the state, yet household contribute almost 20% of the costs of primary education. Following the agreement of the Millennium Development Goals, the first decade of the 21st century saw an important increase in international financial flows under the umbrella of development assistance. Recent estimates show that development assistance for education has stopped growing since 2010, with notable aggregate reductions on flows going to primary education. These changes in the priorization of development assistance for education across levels and regions, can have potentially large distributional effects, particularly within low income countries that depend substantially on this source of funding for basic education.{ref}As per estimates reported in Steer L. and K. Smith (2015), [Financing education: Opportunities for global action](http://files.eric.ed.gov/fulltext/ED568940.pdf). Center for Universal Education. Available Online from the Brookings Institution{/ref} When analysing correlates, determinants and consequences of education consumption, the macro data indicates that national expenditure on education does not explain well cross-country differences in learning outcomes. This is indicative of a complex 'education production function' whereby for any given level of expenditure, output achieved depends crucially on the input mix. Available evidence specifically on the importance of school inputs to produce education, suggests that learning outcomes may be more sensitive to improvements in the quality of teachers, than to improvements in class sizes. Regarding household inputs, the recent experimental evidence suggests that interventions that increase the benefits of attending school (e.g. conditional cash transfers) are particularly likely to increase student time in school; and that those that incentivise academic effort (e.g. scholarships) are likely to improve learning outcomes. Policy experiments have also shown that pre-school investment in demand-side inputs leads to large positive impacts on education – and other important outcomes later in life. The environment that children are exposed to early in life, plays a crucial role in shaping their abilities, behavior and talents. ## Historical perspective on financing education #### When did the provision of education first become a public policy priority? Governments around the world are nowadays widely perceived to be responsible for ensuring the provision of accessible quality education. This is a recent social achievement. The advancement of the idea to provide education for more and more children only began in the mid 19th century, when most of today’s industrialized countries started expanding primary education. The following visualization, plotting public expenditure on education as a share of [Gross Domestic Product ](https://ourworldindata.org/gdp-data/)(GDP) for a number of early-industrialized countries, shows that this expansion took place mainly through public funding.{ref}The source for the visualization below – Tanzi & Schuktnecht (2000) – compiles estimates from many sources, including: League of Nations Statistical Yearbook (various years), Mitchell (1962), OECD Education at a Glance (1996), UNESCO World Education Report (1993), UNDP Human Development Report (1996), UN World Economics Survey (various years). To the extent that the authors do not specify which sources were prioritised for each year/country, it is not possible for us to reliably extend the time series with newer data. For instance, the OECD Education at a Glance report (1998), which presents estimates for the years 1990 and 1995, suggests discrepancies with the values reported by Tanzi & Schuktnecht (2000) for 1993.{/ref} Our entry on [Primary Education and Schools](https://ourworldindata.org/primary-education-and-schools/) provides details regarding how this expansion in funding materialized in better education outcomes for these countries. <Chart url="https://ourworldindata.org/grapher/total-government-expenditure-on-education-gdp?tab=chart"/> #### How did the US finance the expansion of public education? Public schools in the US currently educate more than 90% of all children enrolled in elementary and secondary schools.{ref}As per [2015 enrolment estimates from the NCES.](https://nces.ed.gov/programs/digest/d15/tables/dt15_105.20.asp){/ref} This is the result of a process of education expansion that relied heavily on public funding, particularly from local governments. The visualization shows the sources of revenues for public schools in the US over the last 120 years. As it can be seen, states and localities are – and have always been – the main sources of funding for public primary education in the US. In fact, we observe three broad periods in this graph: there is first a period of stable revenues until 1920, then a period of sharp growth and decline during the interwar years, and then a period of substantial growth since the second world war, slowing down in the 1970s. In all these periods, federal funding was always very small, as can be seen when changing the visualisation from 'absolute' to 'relative'. Disaggregated data from the last couple of decades gives further insights into the specific sources of local revenues for schools in the US: the largest part comes from property taxes (about 80% of local revenues came from property taxes in 2013), while only a very small part comes from fees and donations (private funding for public schools, which is considered a local revenue, amounted to less than 2% of total public school revenues in 2013). This heavily decentralised system relying on property taxes has the potential of creating large inequalities in education, since public schools in affluent urban areas are able to raise more funding from local revenues. Indeed, a significant part of the debate on education inequalities in the US today focuses on the importance of increasing progressive federal spending to reduce inequalities in public school funding.{ref}A [recent article from the Huffington Post](http://www.huffingtonpost.com/2015/03/13/arne-duncan-school-funding-disparities_n_6864866.html) highlights this point, including interesting visualizations documenting the important role that federal funding plays in reducing expenditure inequalities.{/ref} <Chart url="https://ourworldindata.org/grapher/revenues-for-public-schools-by-source-us"/> #### How did France finance the expansion of public education? The case of the US above shows that funding for public schools has been historically a responsibility of local governments. In other countries, such as France, the expansion of public education also took place initially with resources from local governments, but relatively quickly the fiscal burden was shifted to the national level. In France this transition was associated with a sharp jump towards universal access and a concomitant reduction in regional inequalities. The following visualization from Lindert (2004){ref}Lindert, Peter H. _Growing public: Volume 1, the story: Social spending and economic growth since the eighteenth century_. Vol. 1. Cambridge University Press, 2004.{/ref} provides evidence of the French experience. As we can see there are three distinct periods: education spending was initially low and mainly private, then in 1833 funding began growing with local resources after the introduction of a law liberating communes to raise more local taxes for schools, and finally in 1881 the national government took over most of the financial responsibility after the introduction of a new law that abolished all fees and tuition charges in public elementary schools. In the source book, Lindert (2004) provides further evidence of how this transition towards centrally funded public education reduced north-south inequalities in France. ###### Sources of funds for France’s public primary schools, 1820–1913 – Figure 5.5 in Lindert (2004){ref}Lindert, Peter H. _Growing public: Volume 1, the story: Social spending and economic growth since the eighteenth century_. Vol. 1. Cambridge University Press, 2004.{/ref} <Image filename="Lindert-2004-France_EarlyEducation_Breakdown.png" alt="Lindert (2004) France_EarlyEducation_Breakdown"/> #### In the US growth in education expenditure was characterized by growth specifically in the public sector A comparison of expenditure between public and private education institutions is helpful to contextualize the role the public sector played in the process of education expansion in industrialized countries. The following graph does this using data from the National Center for Education Statistics in the US. It shows that during the years 1950-1970 – a period of substantial growth in education expenditure in the US – expenditure grew _specifically_ in the public sector.{ref}Bear in mind that the estimates from the National Center for Education Statistics are not broken down by source of funds. Rather, they show expenditure by type of institution – which is not equivalent, since public institutions may spend private resources, and vice versa.{/ref} <Chart url="https://ourworldindata.org/grapher/us-education-expenditure-as-share-of-gdp-public-and-private"/> #### When did the expansion of basic education become a global phenomenon? The second half of the 20th century marked the beginning of education expansion as a global phenomenon. The visualization, using data from Szirmai (2005){ref} Szirmai, A. (2005) The Dynamics of Socio-Economic Development: An Introduction. Cambridge University Press. {/ref}, shows government expenditure on education as a share of national income for a selection of low and middle-income countries, together with the corresponding average for high-income countries, for the period 1960-2010. As it can be seen, by 1990 government spending on education in many developing countries was already close to the average observed in developed countries. It is important to point out that the remark above makes reference to convergence in expenditure relative to _income_. To the extent that low-income countries remain poorer than high-income countries, gaps in levels of expenditure per pupil are persistently large. Indeed, cross-country heterogeneity in education expenditure per pupil is currently much higher than heterogeneity in expenditure as share of GDP.{ref}In 2010, high income countries spent 6721 US PPP dollars per primary school pupil. Low income countries, in contrast, spent 115 US PPP dollars per pupil (UNESCO EFA Global Monitoring Report 2014). {/ref} One factor contributing to the slower convergence of expenditure per pupil in real terms is the fact that teachers' salaries – [the main component of education expenditure](https://ourworldindata.org/financing-education#where-does-funding-for-education-go-to) – are much higher in high-income countries, because labour has a higher opportunity cost in these countries. In general, the opportunity cost of labour is a key variable that governments in developing countries should factor in when deciding whether to expand education now, rather than later. <Chart url="https://ourworldindata.org/grapher/share-of-education-in-government-expenditure"/> #### Education inequality is falling around the world An important consequence of the global education expansion is a reduction in education inequality across the globe. The following visualization shows this through a series of graphs plotting changes in the Gini coefficient of the distribution of years of schooling across different world regions. The Gini coefficient is a measure of inequality and higher values indicate higher inequality – you can read about the definition and estimation of Gini coefficients in our entry on [income inequality](https://ourworldindata.org/income-inequality/#the-gini-coefficient). The time-series chart shows inequality by age group. It can be seen that as inequality is falling over time, the level of inequality is higher for older generations than it is for younger generations. We can also see that in the reference period education inequality went down every year, for all age groups and in all world regions. Have gains from historical education expansion fully materialized? The breakdown by age gives us a view into the future: as the inequality is lower among today's younger generations, we can expect the decline of inequality to continue in the future. Thus, further reductions in education inequality are still to be expected within developing countries; and if the expansion of global education can be continued, we can speed up this important process of global convergence. ###### Education Gini coefficients by world region for selected age groups, 1960- 2010 – Figure 4 in Crespo Cuaresma et al. (2013){ref}Jesus Crespo Cuaresma, Samir K.C., and Petra Sauer (2013) – Age-Specific Education Inequality, Education Mobility and Income Growth WWWforEurope working paper; Working Paper no 6; Online at [http://www.foreurope.eu/fileadmin/documents/pdf/Workingpapers/WWWforEurope_WPS_no006_MS15.pdf](https://web.archive.org/web/20170811085131/http://www.foreurope.eu/fileadmin/documents/pdf/Workingpapers/WWWforEurope_WPS_no006_MS15.pdf){/ref} <Image filename="Cuaresma-etal2013-edu_gini_1960_2010-.png" alt="Cuaresma etal(2013) edu_gini_1960_2010"/> #### Education inequality can decline rapidly across all levels of education – South Korea is an example The experience of South Korea shows that it is possible to reduce education inequality rapidly across all levels of education. The following visualization show two graphs comparing the concentration of years of education in South Korean between the years 1970 and 2010. To be precise, each of these graphs shows an education Lorenz curve: a plot showing the cumulative percentage of the schooling years across all levels of education on the vertical axis, and the cumulative percentage of the population on the horizontal axis. As it can be seen, in 2010 education was much less concentrated than in 1970, not only because there was a smaller share of individuals without schooling (shown along the bottom of the chart), but also because there was a smaller share of individuals concentrating large proportions of school-years at higher levels of education. Indeed, in only 40 years South Korea was able to double the mean years of schooling (from 6 to 12 years) and at the same time get remarkably close to the 45-degree line marking the hypothetical scenario of perfect equality of schooling. In other entries we show that in this same period South Korea increased drastically its [ GDP per capita](https://ourworldindata.org/gdp-growth-over-the-last-centuries/#real-gdp-per-capita-around-the-world-ppp-adjusted-since-1000-max-roserref) while significantly improving health outcomes, such as [child mortality](https://ourworldindata.org/grapher/child-mortality?country=KOR). ###### Inequality of Educational Attainment in South Korea 1970 and 2010{ref}Data from Petra Sauer (2016) – The Role of Age and Gender in Education Expansion.

The following chart plots trends in public expenditure on education as a share of GDP. As usual, a selection of countries is shown by default, but other countries can be added by clicking on the relevant option at the top of the chart. Although the data is highly irregular due to missing observations for many countries – an issue we discuss in more detail in our section on Data Quality below –, we can still observe a broad upward trend for the majority of countries. Specifically, it can be checked that of the 88 countries with available data for 2000/2010, three-fourths increased education spending as a share of GDP within this decade. As incomes – measured by GDP per capita – are generally increasing around the world, this means that the total amount of global resources spent on education is also increasing in absolute terms. <Chart url="https://ourworldindata.org/grapher/total-government-expenditure-on-education-gdp"/> You can explore the trends by education level in these interactive charts: * [Government expenditure on pre-primary education as share of GDP](https://ourworldindata.org/grapher/government-expenditure-on-pre-primary-education-as-share-of-gdp) * [Government expenditure on primary education as share of GDP](https://ourworldindata.org/grapher/government-expenditure-on-primary-education-as-share-of-gdp) * [Government expenditure on secondary education as share of GDP](https://ourworldindata.org/grapher/government-expenditure-on-secondary-education-as-share-of-gdp) * [Government expenditure on tertiary education as share of GDP](https://ourworldindata.org/grapher/government-expenditure-on-tertiary-education-as-share-of-gdp) #### Is additional funding for education taking resources from other sectors? The above-mentioned growth in overall government expenditure on education as a share of GDP cannot be entirely attributed to a wide-spread change in the prioritization of education spending within domestic budgets. The following visualization shows government expenditure on education as a share of total government expenditure. In this case the available data does not suggest a discernible global pattern. For instance, of the 36 countries with available data for 2000 to 2010, only around half increased spending on education relative to the other sectors. The data does suggest, however, that there is large and persistent cross-country heterogeneity in the relative importance of education vis-a-vis other sectors, even within developing countries. For example, in 2011 education accounted for about 8% of government spending in the Central African Republic, while it accounted for about 30% in Ghana. <Chart url="https://ourworldindata.org/grapher/share-of-education-in-government-expenditure"/> #### European countries tend to assign a lower share of public budgets to education, relative to the amount of their income that is devoted to education Generally speaking, countries that spend a large share of their income on education also tend to prioritize education highly within their budgets. The following visualization presents a snapshot of government spending on education around the world for the year 2016. Specifically, this graph plots government expenditure on education as a share of GDP in the vertical axis, and government expenditure on education as a share of total government expenditure in the horizontal axis. Each dot on this chart represents a different country, with the assigned colors denoting different world regions. As we can see, there is a positive correlation, but regional differences are stark: for almost every level of spending as a share of GDP along the horizontal axis, European countries (marked in light orange) spend a smaller budget share on education. <Chart url="https://ourworldindata.org/grapher/share-edu-spending-gdp-vs-share-edu-total-spending"/> #### In European countries the weight of primary education within total education spending is lower than in other countries In comparison to countries where education started expanding later, European countries tend to assign relatively more of their government education budgets to the secondary and tertiary levels, while at the same time devoting relatively less of their general government budgets to education as a whole. This can be appreciated in the following visualization, where the priorization of primary education (i.e. the share of primary education within the education budget) is plotted against the overall priorization of education (i.e. the share of education within the entire government budget). It can be seen that European countries (marked again in light orange) are mostly located in the bottom-left. And there is a weak positive correlation between the variables, both across all countries and across European countries.{ref}For reference, the correlation for all countries in this scatter plot is 0.24.{/ref} <Chart url="https://ourworldindata.org/grapher/primary-edu-spending-vs-overall-edu-spending"/> #### In high-income countries households shoulder a larger share of education expenditures at higher education levels than at lower levels – but in low-income countries this is not the case The following visualization shows the percentage of total education expenditures contributed directly by households in 15 high income countries and 15 low/middle income countries (most recent data available on 2014). The top chart in this figure, corresponding to high income countries, shows a very clear pattern: households contribute the largest share of expenses in tertiary education, and the smallest share in primary education. Roughly speaking, this pattern tends to be progressive, since students from wealthier households are more likely to attend tertiary education, and those individuals who attend tertiary education are likely to perceive large private benefits (more on this in our entry on [Skill Premium](https://ourworldindata.org/skill-premium-income-by-education/)).{ref}Strictly speaking, for this spending pattern to be truly progressive there must be subsidies or income-contingent loans to guarantee that low-income students can also access tertiary education and reap the private benefits from this type of investment.{/ref} In contrast, the bottom chart shows a very different picture: in several low-income countries households contribute proportionally more to primary education than to higher levels. Malawi is a notable case in point – tertiary education is almost completely subsidised by the state, yet household contribute with almost 20% of the costs in primary education. Such distribution of private household contributions to education is regressive. ###### Percentage of total education expenditures contributed directly by households in 30 countries, grouped by country income – Figure 32 in [The Investment Case for Education and Equity (UNICEF - 2015)](http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf) <Image filename="UNICEF-Private-Education-Expenditure-Levels.png" alt="UNICEF Private Education Expenditure Levels"/> ## Recent funding structures in OECD countries #### Primary education continues to be publicly funded in industrialized countries We have already mentioned that those countries that pioneered the expansion of primary education in the 19th century – all of which are current OECD member states – relied heavily on public funding to do so. Today, public resources still dominate funding for the primary, secondary and post-secondary non-tertiary education levels in these countries. While in the last decade the share of public funding for these levels of education has decreased slightly, the broad pattern is remarkably stable. The visualization presents OECD-average expenditure on education institutions by source of funds.{ref}The OECD provides country-specific figures. However, there is relatively little variation across OECD countries in this respect. This is explained by near-universal enrolment rates at these levels of education and the demographic structure of the population.{/ref} By clicking on the option labeled 'relative' you can see the corresponding share of each source: private funding went up from 7.9% in 2000, to 9.4% in 2012. The role of public funding for other levels of education is however quite different. At the tertiary level public sources account for less than 70% of funding on average (2012 figures). Below we provide evidence of the pre-school level. <Chart url="https://ourworldindata.org/grapher/average-oecd-education-expenditure-by-source-of-funding-gdp"/> #### Publicly funded pre-primary education is more strongly developed in the European countries of the OECD High-income countries tend to have better developed pre-primary education systems than lower-income countries. However, within high-income countries there is substantial heterogeneity in the extent to which pre-primary education is publicly financed. The visualization presents expenditure on pre-primary educational institutions as a share of GDP across the OECD. As it can be seen, publicly funded pre-primary education tends to be more strongly developed in the European than the non-European countries of the OECD. In fact, the OECD reports that in Europe the concept of universal access to education for 3-6 year-olds is generally accepted: most countries in this region provide all children with at least two years of free, publicly funded pre-primary education in schools before they begin primary education. ###### Expenditure on pre-primary educational institutions (% of GDP), OECD, 2012 – Figure C2.4 in [Education at a Glance (2015)](http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1) <Image filename="OECD_Expenditure_Pre-primary.png" alt="OECD_Expenditure_Pre-primary"/> #### Where does funding for education go to? The largest part of funding devoted to education in OECD countries goes to finance current expenditures, mainly compensation of staff – specifically, teachers. The following two charts, taken from the OECD's report [Education at a Glance (2015)](http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1), highlight the labour-intensive nature of education. In the lower levels of education (i.e. primary, secondary and post-secondary non-tertiary) the share of current expenditure is very large and exhibits little cross-country variation – between 90 and 97 percent of total expenditure corresponds to current expenditure across all of the OECD countries. In higher levels of education (i.e. tertiary) there is more cross-country variation, but current expenditure still dominates by a large margin across all countries. ###### Distribution of current and capital expenditure on educational institutions – Figure B6.2 in [Education at a Glance (2015)](http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1) <Image filename="OECD_Expenditure_Education_Resources-.png" alt="OECD_Expenditure_Education_Resources"/> #### What drives current expenditure on education? In the figures above we noted the importance of current expenditure in the production of education. The following table provides further details regarding the type of expenditures that comprise current spending. Specifically, this chart shows a breakdown of expenditure for tertiary-level institutions in the US (public and private), during the period 1980-1997. It shows that instruction accounts for almost half of expenditure; and while there are some small differences across sectors, there is a fair amount of stability in expenditures across time. This serves as a benchmark for lower education levels, where instruction takes an even larger share of expenditure.{ref}This is a stylized fact of OECD education spending. In all the OECD countries, the share of spending devoted to compensation of teachers is by far the largest component of current expenditure. Moreover, expenditure on teachers' compensation is larger at the combined primary, secondary and post-secondary non-tertiary levels of education than at the tertiary level. See Table B6.2 in [Education at a Glance (2015)](http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1) for details on the breakdown of current expenditure across all OECD countries by education level. {/ref} ###### Percent distribution of college and university current expenditures in the US, by control over time – Table 8 in Welch and Hanushek (2006){ref}Welch, F., & Hanushek, E. A. (2006). Handbook of the Economics of Education, Two Volumes. North Holland.{/ref} <Image filename="US_CurrentExpenditure_Types.png" alt="US_CurrentExpenditure_Types"/> ## International financing flows #### Education financing in developing countries has been largely affected by development assistance Following the agreement of the Millennium Development Goals, the first decade of the 21st century saw an important increase in international financial flows under the umbrella of development assistance (often also called development aid, or simply 'aid'). The following chart shows total OECD development assistance flows for education by level, in constant 2013 US dollars, for the period 2002-2013. As it can be seen, there are two distinct periods: in 2003-2010 flows for education increased substantially, more than doubling in real terms across all levels of education; and in the years 2010-2013 funding for basic education _decreased_, while funding for secondary and post-secondary education remained relatively constant. For many low income countries, where development assistance contributes a substantial share of funding for education, this marked change in trends is important. As a reference, in 2012 development assistance accounted for more than 20 percent of all domestic spending on basic education in recipient low-income countries.{ref}Steer L. and K. Smith (2015), [Financing education: Opportunities for global action](http://files.eric.ed.gov/fulltext/ED568940.pdf). Center for Universal Education.

Specifically, the share of development assistance for primary education going to sub-Saharan Africa has been decreasing sharply since the agreement of the Millennium Development Goals. The following chart shows this: sub-Saharan Africa’s share in total aid to primary education declined from 52 percent in 2002 to 30 percent in 2013, while the continent’s share in the total number of out-of-school children rose from 46 percent to 57 percent. This pattern is something specific to the education sector within the broader development assistance landscape: in the healthcare sector the overall slowdown of flows started a couple of years later, was less abrupt, and affected proportionally less the sub-Saharan countries.{ref}The share of development assistance going to sub-Saharan Africa has decreased as a whole – from 55 percent in 2002 to 40 percent in 2013 –, but as we note the drop specifically for primary education has been steeper.{/ref} Indeed, recent studies further highlight that development assistance for education is significantly different to assistance for healthcare in other ways: the education sector attracts less earmarked funding through multilaterals, and includes a smaller proportion of resources that developing governments can directly control for programming.{ref}Steer L. and K. Smith (2015), [Financing education: Opportunities for global action](http://files.eric.ed.gov/fulltext/ED568940.pdf). Center for Universal Education.

But for any given country, with a determined income distribution and demographic structure, the extent to which public spending on education contributes to reduce inequality depends crucially on the way in which spending is focused across education levels. The recent UNICEF report [The Investment Case for Education and Equity](http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf) shows that in low income countries, on average 46 percent of public resources are allocated to the 10 percent of students who are most educated – while this figure goes down to 26 and 13 percent in lower-middle and upper-middle income countries respectively. The following visualization shows further details on the concentration of public spending across different countries. The vertical axis shows the percentage of public education resources going to the 10% most educated or 10% least educated students – as we can see expenditure is heavily concentrated at the top in many low income countries. The earlier remarks about trends in international education financing flows (namely that aid is very important in low-income countries, and that a relatively low and shrinking share of aid is going to primary levels), suggest that inequality in public spending will worsen in low income countries. Yet development assistance priorities have a scope for changing this.{ref}The conclusion from these figures is that, while public spending does reduce education inequality in low income countries, remaining inequalities could be further reduced by shifting resources towards lower levels of education. This evidently does not mean that resources _should_ be shifted – low income countries and aid donors may have other objectives apart from reducing inequality. But the case for reducing inequality at the bottom is very strong, and some studies suggest that returns to education at the primary level might be higher than at post-primary levels in low income countries (for a discussion of the vast literature on returns to education, and the ongoing debate on the validity of estimates, see Heckman, J. J., Lochner, L. J., & Todd, P. E. (2006). Earnings functions, rates of return and treatment effects: The Mincer equation and beyond. Handbook of the Economics of Education, 1, 307-458. ).{/ref} ###### Percentage of public education resources going to the 10% most educated or 10% least educated students – Figure 29 in [The Investment Case for Education and Equity (UNICEF - 2015)](http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf) <Image filename="UNICEF-Education-Expenditure-Concentration.png" alt="UNICEF Education Expenditure Concentration"/> ## What determines educational finance? ### The big picture #### Why do governments finance education? One of the reasons to justify government intervention in the market for education, is that education generates positive externalities.{ref}That positive externalities justify government intervention in the provision of education is essentially an efficiency argument. The logic is that individuals may not spend enough on education because they fail to internalize the positive effect that their education has on other people. But there are, of course, also equity arguments to justify government intervention in the provision of education – for instance, reducing inequality in education may be of intrinsic value, or may be instrumental in reducing inequalities in other outcomes.{/ref} This essentially means that investing in education yields both private and social returns. Private returns to education include higher wages and better employment prospects. Social return include pro-social behaviour (e.g. volunteering, political participation) and interpersonal [trust](https://ourworldindata.org/trust/). The following chart uses OECD results from the Survey of Adult Skills to show how self-reported trust in others correlates with educational attainment. More precisely, this chart plots the percentage-point difference in the likelihood of reporting to trust others, by education level of respondents. Those individuals with upper secondary or post-secondary non-tertiary education are taken as the reference group, so the percentage point difference is expressed in relation to this group. As we can see, in all countries those individuals with tertiary education were by far the group most likely to report trusting others. And in almost every country, those with post-secondary non-tertiary education were more likely to trust others than those with primary or lower secondary education. The OECD's report [Education at a Glance (2015)](http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1) provides similar descriptive evidence for other social outcomes. The conclusion is that adults with higher qualifications are more likely to report desirable social outcomes, including good or excellent health, participation in volunteer activities, interpersonal trust, and political efficacy. And these results hold after controlling for literacy, gender, age and monthly earnings. ###### Likelihood of reporting to trust others, by educational attainment, OECD 2012 – Figure A8.4 in [Education at a Glance (2015)](http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1){ref}As per the source notes: "Percentage-point difference reflects the relative change of reporting to trust others compared to the reference category. For example, in Norway, the percentage of individuals with tertiary education reporting to trust others increases by 20 percentage points compared to someone who has upper secondary or post-secondary non-tertiary education. Similarly, after accounting for literacy proficiency, the percentage of individuals with tertiary education increases by 16 percentage points compared to someone who has upper secondary or post-secondary non-tertiary education."{/ref} <Image filename="OECD_Education_Trust.png" alt="OECD_Education_Trust"/> #### Do countries that spend more public resources on education tend to have better education outcomes? Education outcomes are typically measured via 'quantity' output (e.g. years of schooling) and ['quality' output](https://ourworldindata.org/quality-of-education) (e.g. learning outcomes, such as test scores from the Programme for International Student Assessment – PISA). The following visualization presents three scatter plots using 2010 data to show the cross-country correlation between (i) education expenditure (as a share of GDP), (ii) mean years of schooling, and (iii) mean PISA test scores. At a cross-sectional level, expenditure on education correlates positively with both quantity and quality measures; and not surprisingly, the quality and quantity measures also correlate positively with each-other. But obviously correlation does not imply causation: there are many factors that simultaneously affect education spending and outcomes. Indeed, these scatterplots show that despite the broad positive correlation, there is substantial dispersion away from the trend line – in other words, there is substantial variation in outcomes that does not seem to be captured by differences in expenditure. ###### Correlation between education outcomes and education expenditure (2010 data){ref}Data on expenditure corresponds to 2010 total government education expenditure across all levels, as a share of GDP (source: World Bank Education Statistics). Data on PISA scores corresponds to 2010 mean average test scores across categories – mathematics, reading and science (source: OECD PISA). Data on years of schooling corresponds to 2010 mean years of schooling for the population aged 15 and over (source: Barro Lee Education dataset){/ref} <Image filename="Edu_OutcomesVsExpenditure.png" alt="Edu_OutcomesVsExpenditure"/> #### Does cross-country variation in government education expenditure explain cross-country differences in education outcomes? The following visualization presents the relationship between PISA reading outcomes and average education spending per student, splitting the sample of countries by income levels. It shows that income is an important factor that affects both expenditure on education and education outcomes: we can see that above a certain national income level, the relationship between PISA scores and education expenditure per pupil becomes virtually inexistent. Several studies with more sophisticated econometric models corroborate the fact that expenditure on education does not explain well cross-country differences in learning outcomes.{ref}For a discussion of evidence supporting this claim, see Hanushek, E. A., (2006). School Resources. Handbook of the Economics of Education, 2.{/ref} You can read more about test scores and learning outcomes in our entry on [Quality of Education](https://ourworldindata.org/quality-of-education-drop-out-rates/). ###### Average reading performance in PISA and average spending per student from the age of 6 to 15 - Figure 1 in OECD (2012){ref} Does money buy strong performance in PISA? - OECD.

The fact that expenditure on education does not explain well cross-country differences in learning outcomes is indicative of the intricate nature of the process through which such outcomes are produced. Borrowing the terms from the economics literature, the following ‘production function’ provides a conceptual framework to think about the determinants of learning outcomes{ref}P. Glewwe, K. Muralidharan (2016). _[Improving Education Outcomes in Developing Countries: Evidence, Knowledge Gaps, and Policy Implications](https://www.sciencedirect.com/science/article/pii/B9780444634597000105)_. Handbook of the Economics of Education, Volume 5.{/ref}: [latex]A=a(s,\mathbf{Q},\mathbf{C},\mathbf{H},\mathbf{I})[/latex] where _A_ is skills learned (achievement), _s_ is years of schooling, **Q** is a vector of school and teacher characteristics (quality), **C** is a vector of child characteristics (including "innate ability"), **H** is a vector of household characteristics, and **I** is a vector of school inputs under the control of households, such as children’s daily attendance, effort in school and in doing homework, and purchases of school supplies. This conceptualization highlights that, for any given level of expenditure, the output achieved will depend on the input mix. And consequently, this implies that in order to explain education outcomes, we must rely on information about specific inputs. In the following sections we explore evidence regarding the returns to household inputs (i.e. different elements of **Q**) and demand-side inputs (i.e. elements of **C,H** and **I**). ### School inputs #### Each education system is different, but improving teacher quality is often more effective to improve learning outcomes than increasing the number of teachers per pupil A vast number of studies have tried to estimate the impact of classroom resources on learning outcomes. The following table summarizes results from the systematic review in Hanushek (2006){ref}Hanushek, E. A., (2006). School Resources. Handbook of the Economics of Education, Volume 2. Elsevier.{/ref}. In this table, the left-hand side summarizes results from econometric studies focusing on developing countries, while the right-hand side presents evidence from the US (where studies have concentrated extensively). We can see that for all listed inputs and across all countries, the share of studies that have found a positive effect is small – in fact, the majority of studies find either no effect, or a negative effect. This clearly does not mean that these classroom resources are not important, but rather that it is very difficult to know with confidence when and where they are a binding constraint to improve learning outcomes. A first conclusion, therefore, seems to be that context and input mix are fundamental to improving outcomes – even in developing countries where the expected returns to additional resources is large across the board. Taking the ratio of positive to negative effects detected in the literature as a proxy for what tends to work best, we can derive a second conclusion from the table: spending more resources on better teachers (i.e. improving teacher experience and teacher education) tends to work better to improve learning outcomes than simply increasing the number of teachers per pupil. And this seems to be true both in developed and developing countries. This last conclusion is consistent with the main message from the OECD's report [Does money buy strong performance in PISA?](http://www.oecd.org/pisa/pisaproducts/pisainfocus/49685503.pdf), which points out that countries that prioritised the quality of teachers over class sizes performed better in PISA tests.{ref} This claim is clearly only descriptive, since there are many underlying variables that simultaneously drive teacher characteristics and student outcomes in any particular country. Indeed, most of the available evidence on whether teacher quality and quantity matters is difficult to interpret causally, as it is hard to find instances where teacher quality / quantity varies exogenously. A recent study concludes on the topic: _ "teachers vary in many ways, but we found no high-quality studies that have examined the impact of teacher characteristics on student learning or time in school" _(source: page 696, Glewwe, P. and Muralidharan, K. (2016) [Improving Education Outcomes in Developing Countries: Evidence, Knowledge Gaps, and Policy Implications](https://www.sciencedirect.com/science/article/pii/B9780444634597000105). Handbook of the Economics of Education, Volume 5. ) {/ref} And it is also consistent with a recent high-quality study on the impact of teacher quality on test scores using data from the US, which suggests that improvements in teacher quality can causally raise students’ test scores (evidence from Chetty et al. (2014){ref}Chetty, Raj, John N. Friedman, and Jonah E. Rockoff. 2014. “Measuring the Impacts of Teachers I: Evaluating Bias in Teacher Value-Added Estimates.” American Economic Review, 104(9): 2593-26{/ref} – see our entry on [Quality of Education ](https://ourworldindata.org/quality-of-education#teacher-quality)for a discussion of their results). ###### Percentage distribution of estimated effect of selected key resources on student performance – based on Tables 3 and 6 in Hanushek (2006){ref}Hanushek, E. A., (2006). School Resources. Handbook of the Economics of Education, 2.{/ref} <Image filename="Hanushek_Supply_Interventions.png" alt="Hanushek_Supply_Interventions"/> #### Remedial teaching can yield substantial improvements in learning outcomes Education in low-income countries is particularly difficult because there is substantial heterogeneity in the degree of preparation that children have when they enter school – much more so than in high-income countries. Recent evidence from policy 'experiments' in developing countries suggests remedial teaching, in the form of assistants teaching targeted lessons to the bottom of the class, can yield substantial improvements in learning outcomes. The following visualization summarizes the effects of four different policy treatments within the so-called Teacher Community Assistant Initiative (TCAI) in Ghana – this is an initiative that evaluated four different such remedial teaching interventions.{ref}Further details in Innovations for Poverty Action, 2014. Implementation Lessons: The Teacher Community Assistant Initiative (TCAI). Available online from [www.poverty-action.org](http://www.poverty-action.org/sites/default/files/publications/TCAI_Final%20Results_040115.pdf) {/ref} The units in this figure are standard deviations of test results. The first two sets of estimates correspond to the test-score impacts of enabling community assistants to provide remedial instruction specifically to low-performing children, either during school, or after school. The third set of estimates corresponds to test-score impacts of providing a community assistant and reducing class size, without targeting instruction to low-performing pupils. And the last set of results corresponds to testing the effect of training teachers to provide small-group instruction targeted at pupils’ actual learning levels. As we can see, while all interventions had a positive effect, the lowest impacts – across all tests – come from the non-targeted 'normal curriculum' intervention that reduced class sizes, and from the intervention that provided training to teachers on how to engage in targeted remedial teaching themselves. This suggests that the improvements in outcomes were caused by the combination of targeted instruction and TCAs who, unlike teachers, were specifically dedicated to this purpose. These results are consistent with findings from across Africa, suggesting that teaching at the right level causes better learning outcomes in a cost-effective way (see Glewwe and Muralidharan 2016{ref}Glewwe, P. and Muralidharan, K.

We have already made the point that the bulk of education expenditure goes specifically towards financing teachers. And we have also pointed out that improving teacher quality may be a particularly good instrument to improve teaching outcomes. This leads to a natural question: are pay-for-performance teacher contracts an effective instrument to improve learning outcomes? A growing body of literature in the economics of education has started using randomized control trials (i.e. policy 'experiments') to answer this question. Glewwe and Muralidharan (2016){ref}Glewwe, P. and Muralidharan, K. (2016) [Improving Education Outcomes in Developing Countries: Evidence, Knowledge Gaps, and Policy Implications](https://www.sciencedirect.com/science/article/pii/B9780444634597000105). Handbook of the Economics of Education, Volume 5. Elsevier. (Link only to working paper){/ref} provide the following account of the available evidence: -- undefined The conclusion is that well-designed pay-for-performance contracts are a cost-effective instrument to boost test scores; but this does not mean that they are necessarily effective at achieving other – perhaps equally important – objectives of time spent in school. In simple words, it is possible that pay-for-performance yields 'teaching to the test'. Alternative incentive mechanisms, such as community-based monitoring of teachers, have been proposed as an alternative. Glewwe and Muralidharan (2016) also provide a review of the – somewhat limited – available evidence on such alternative incentive mechanisms.{ref}They conclude that "evidence on the impact of monitoring on time in school is scarce and not encouraging...[while] the evidence of the impact of monitoring on student learning is only somewhat more encouraging"{/ref} ### Household inputs #### School attendance and student effort are responsive to incentives Demand-side inputs are as important as supply-side inputs to produce education. Attending school and exerting effort are perhaps the most obvious examples: without these inputs even the best endowed schools will fail to deliver good outcomes. The table summarizes information on different demand-side investments that have shown to successfully improve quality and quantity outcomes. More precisely, this table gathers evidence from randomized control trials in developing countries, as per the review in Glewwe and Muralidharan (2016). The reported figures correspond to positive/negative significant/insignificant estimates across a set of available experimental studies (bear in mind some studies estimate more than one effect – e.g. by measuring outcomes at several points in time). As we can see, the evidence suggests interventions that increase the benefits of attending school – such as conditional cash transfers – are likely to increase student time in school. And those that increase the benefits of higher effort and better academic performance – such as merit scholarships – are likely to improve learning outcomes (see Glewwe and Muralidharan 2016 for further details on the underlying policy interventions, plus further evidence and discussion of results). ###### Summary of impacts for selected demand-side interventions on education outcomes in developing countries – based on Tables 4 and 5 from Glewwe and Muralidharan (2016){ref}Glewwe, P. and Muralidharan, K. (2016) [Improving Education Outcomes in Developing Countries: Evidence, Knowledge Gaps, and Policy Implications](https://www.sciencedirect.com/science/article/pii/B9780444634597000105).

(Link only to working paper){/ref} <Image filename="Glewwe2016_DemandInterventions_RCTs-1.png" alt="Glewwe2016_DemandInterventions_RCTs"/> #### Targeting health problems can be a particularly cost-effective way of increasing school attendance In many low-income countries, health problems are an important factor preventing children from attending school. The following visualization presents a comparison of the impact that a number of different health interventions have achieved in different countries – together with some non-health-related interventions that serve as reference. The height of each bar in this graph reflects the additional school years achieved per hundred dollars spent on the corresponding intervention; so these estimates can be interpreted as a measure of how cost-effective the different interventions are.{ref}Bear in mind that the reported gains in school years are a measure of the _total_ impact of the program across the treated population, rather than impact per treated student. Further information on cost-effectiveness analysis is available from the source of the graph.{/ref} We see that treating children for intestinal worms (labeled 'deworming' in the chart) led to an additional 13.9 years of education for every $100 spent in Kenya; while a program targeting anaemia (labeled 'iron fortification') led to 2.7 additional years per $100 in India. These interventions seem to be much more cost-effective to improve test scores than conditional cash transfers, free school uniforms, or merit scholarships (further details on all interventions available from Dhaliwal et al. 2012{ref}Dhaliwal, I., Duflo, E., Glennerster, R., & Tulloch, C. (2013). [Comparative cost-effectiveness analysis to inform policy in developing countries: a general framework with applications for education](http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.570.2412&rep=rep1&type=pdf). Education Policy in Developing Countries, 285-338.{/ref}). Of course, ranking these interventions is not trivial since most programmes achieve multiple outcomes – indeed, we have already discussed that remedial teaching is generally effective to increase test-scores, although here we see a particular instance where it had no impact on school attendance. Nevertheless, health interventions seem to be particularly interesting, since they lead to substantial achievements in both education _and_ health outcomes (for a recent analysis of the literature on the impacts of mass deworming see Croke et al. 2016{ref}Croke, Kevin, Joan Hamory Hicks, Eric Hsu, Michel Kremer, and Edward Miguel. 2016. “[Does Mass Deworming Affect Child Nutrition?

The environment that children are exposed to early in life, plays a crucial role in shaping their abilities, behavior and talents. To a great extent, this is what drives large and remarkably persistent gaps in the education achievement between individuals in the same country, but in different socioeconomic environments. Cunha et al. (2006) provide a detailed account of the theory and evidence behind this claim, and discuss its implications for the design of education policies. In the chart we see the impacts from the Perry Preschool Program – a flagship experimental intervention study, designed to test the impact of pre-school education on subsequent education outcomes.{ref}More specifically, the Perry pre-school 'experiment' consisted in enrolling 65 randomly selected black children in a pre-school program, and comparing their outcomes later in life against those achieved by a control group of roughly the same size. The treatment consisted of a daily 2.5-hour classroom session on weekday mornings and a weekly 90-minute home visit by the teacher on weekday afternoons to involve the mother in the child's educational process. More information and details on the intervention are available in Cunha et al. (2006).{/ref} The chart shows disadvantaged children participating in the pre-school program (the 'treatment group') had higher grades and were more likely to graduate from high school than the reference control group. Moreover, they spent substantially less time in special education. Other programs have similarly shown evidence of very large and persistent returns to early education interventions. ###### Educational effects from participating in the Perry Preschool Program – Figure 14B in Cunha et al (2006){ref}Cunha, F., Heckman, J.

The same data is also then published by the World Bank ([World Bank EdStats](http://datatopics.worldbank.org/education/) and [World Development Indicators](http://databank.worldbank.org/data/reports.aspx?source=world-development-indicators)) and [Gapminder](https://www.gapminder.org). It is also the main source of education data for most UN reports – such as the EFA Global Monitoring Report (UNESCO), the Human Development Report (UNDP), the State of the World’s Children report (UNICEF) and the Millennium Development Goals (UN). The UIS database is produced mainly from yearly national reports, but it also relies on reports from international organizations.{ref} The [official documentation](http://www.uis.unesco.org/Education/Documents/Background_information_on_education_statistics.pdf) says: "The UIS collects education statistics in aggregate form from official administrative sources at the national level. Collected information encompasses data on educational programmes, access, participation, progression, completion, literacy, educational attainment and human and financial resources. These statistics cover formal education in public (or state) and private institutions (pre-primary, primary, basic and secondary schools, and colleges, universities and other tertiary education institutions); and special needs education (both in regular and special schools)".{/ref} Specifically, countries in the European Union, or members of the OECD, have richer data, since they collect information through the UIS-OECD-Eurostat (UOE) survey, which is more detailed than the UIS survey (see more at [FAQ-UIS](http://www.uis.unesco.org/Education/Pages/FAQ.aspx#sthash.hZOv7Ole.dpuf)) Another, related but different source of education expenditure data, is the International Food Policy Research Institute (IFPRI), which publishes the Statistics of Public Expenditure for Economic Development (SPEED). This source relies primarily on data from the International Monetary Fund (IMF). ### Definitions In the UIS database, government expenditure on education includes spending by local/municipal, regional and national governments, on public and private educational institutions, education administration, and subsidies for private entities (students/households and other privates entities). This information is then reported by level of education, and typically as a share of national income (GDP) or as a share of total public expenditure. In principle, expenditure on pre-primary levels as well as expenditure sourced with transfers from international sources to government, are included. In practice, however, many countries under report these specific figures. ### Measurement limitations The UIS has been maintained since 1999 with the intent of providing comparable expenditure figures across countries and time, and its estimates rely on reports submitted by ministries and national statistics offices. Since reporting is delegated typically to ministries of education, in some instances data on total public expenditure on education fails to represent spending by other ministries that also have budgets for education. Additionally, since not all countries have (or update) national education accounts, the UIS attempts to generate estimates and impute missing data using information from national publications, official websites and other sources. However, the UIS dataset has several missing observations, particularly for years prior to 2010. To gauge the extent to which UIS data is reliable, the following visualization shows the proportions of regular and irregular data that countries make available (where ‘Regular’ means data is available at least once every 3 years; and ‘Irregular’ means data is available less frequently than every 3 years). As can be seen, the picture is not particularly encouraging: less than half of the countries reported regularly data on total government expenditure on education over the reference period. ###### Availability of education financing data in the UIS database, 2005-2013, as a percentage of all (214) countries – Figure 1 in UNESCO–UIS (2016){ref}UNESCO–UIS (2016). A roadmap to better data on education financing. [INFORMATION PAPER NO. 27](http://www.uis.unesco.org/Education/Documents/a-roadmap-to-better-data-on-education-financing.pdf).{/ref} <Image filename="UIS-Data-Quality.png" alt="UIS Data Quality"/> Apart from the above-mentioned issues regarding the availability of data, comparing education financing between different countries can be challenging because the way that expenses are categorized is not always consistent. This can be particularly difficult when it comes to expenses that could potentially be classified as education or non-education-related, like teaching hospitals or transportation. While this issue is not as significant in other sectors like healthcare, it still presents some difficulties. For a further discussion of these issues see the [UIS data collection manual ](http://www.uis.unesco.org/Library/Documents/UOE-data-collection-manual-formal-education-concepts-definitions-classifications-2015-en.pdf). ## Data Sources ### Long-run estimates of education financing As it has been mentioned, the earliest data on financing of education dates back to the late 19th century, when today's industrialized countries began expanding their education systems.

Data from this early period shows that government funds to finance the expansion of education came from a number of different sources, but specifically taxes at the local level played a crucial role. The historical role of local funding for public schools is important to help us understand changes \u2013 or persistence\u2013 in regional inequalities.</p>\n\n\n\n<p>The second half of the 20th century marked the beginning of education expansion as a global phenomenon. Available data shows that by 1990 government spending on education as a share of national income in many developing countries was already close to the average observed in developed countries.{ref}As per estimates from Adam Szirmai, (2015) The Dynamics of Socio-Economic Development, <a href=\"https://web.archive.org/web/20191223132520/http://www.dynamicsofdevelopment.com:80/\">www.dynamicsofdevelopment.com</a>{/ref}</p>\n\n\n\n<p>This global education expansion in the 20th century resulted in a historical reduction in education inequality across the globe: in the period 1960-2010 education inequality went down every year, for all age groups and in all world regions. Recent estimates of education inequality across age groups suggest that further reductions in schooling inequality are still to be expected within developing countries.{ref}As per estimates of Gini coefficients for the distribution of school years in Crespo Cuaresma, J., KC, S., & Sauer, P.

Yet behind these broad global trends there is substantial cross-country \u2013 and cross-regional \u2013 heterogeneity. In high-income countries, for instance, households shoulder a larger share of education expenditures at higher education levels than at lower levels \u2013 but in low-income countries this is not the case. Malawi is a stark example: tertiary education is almost completely subsidised by the state, yet household contribute almost 20% of the costs of primary education.</p>\n\n\n\n<p>Following the agreement of the Millennium Development Goals, the first decade of the 21st century saw an important increase in international financial flows under the umbrella of development assistance. Recent estimates show that development assistance for education has stopped growing since 2010, with notable aggregate reductions on flows going to primary education. These changes in the priorization of development assistance for education across levels and regions, can have potentially large distributional effects, particularly within low income countries that depend substantially on this source of funding for basic education.{ref}As per estimates reported in Steer L. and K. Smith (2015), <a href=\"http://files.eric.ed.gov/fulltext/ED568940.pdf\">Financing education: Opportunities for global action</a>. Center for Universal Education. Available Online from the Brookings Institution{/ref}</p>\n\n\n\n<p>When analysing correlates, determinants and consequences of education consumption, the macro data indicates that national expenditure on education does not explain well cross-country differences in learning outcomes. This is indicative of a complex ‘education production function’ whereby for any given level of expenditure, output achieved depends crucially on the input mix.</p>\n\n\n\n<p>Available evidence specifically on the importance of school inputs to produce education, suggests that learning outcomes may be more sensitive to improvements in the quality of teachers, than to improvements in class sizes. Regarding household inputs, the recent experimental evidence suggests that interventions that increase the benefits of attending school (e.g. conditional cash transfers) are particularly likely to increase student time in school; and that those that incentivise academic effort (e.g. scholarships) are likely to improve learning outcomes.</p>\n\n\n\n<p>Policy experiments have also shown that pre-school investment in demand-side inputs leads to large positive impacts on education \u2013 and other important outcomes later in life. The environment that children are exposed to early in life, plays a crucial role in shaping their abilities, behavior and talents.</p>\n\n\n\n<h2>Historical perspective on financing education</h2>\n\n\n\n<h4>When did the provision of education first become a public policy priority?</h4>\n\n\n\n<p>Governments around the world are nowadays widely perceived to be responsible for ensuring the provision of accessible quality education. This is a recent social achievement. The advancement of the idea to provide education for more and more children only began in the mid 19th century, when most of today\u2019s industrialized countries started expanding primary education. The following visualization, plotting public expenditure on education as a share of <a href=\"https://ourworldindata.org/gdp-data/\">Gross Domestic Product </a>(GDP) for a number of early-industrialized countries, shows that this expansion took place mainly through public funding.{ref}The source for the visualization below \u2013 Tanzi & Schuktnecht (2000) \u2013 compiles estimates from many sources, including: League of Nations Statistical Yearbook (various years), Mitchell (1962), OECD Education at a Glance (1996), UNESCO World Education Report (1993), UNDP Human Development Report (1996), UN World Economics Survey (various years). To the extent that the authors do not specify which sources were prioritised for each year/country, it is not possible for us to reliably extend the time series with newer data. For instance, the OECD Education at a Glance report (1998), which presents estimates for the years 1990 and 1995, suggests discrepancies with the values reported by Tanzi & Schuktnecht (2000) for 1993.{/ref} Our entry on <a href=\"https://ourworldindata.org/primary-education-and-schools/\">Primary Education and Schools</a> provides details regarding how this expansion in funding materialized in better education outcomes for these countries.</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/total-government-expenditure-on-education-gdp?tab=chart\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>How did the US finance the expansion of public education?</h4>\n\n\n\n<p>Public schools in the US currently educate more than 90% of all children enrolled in elementary and secondary schools.{ref}As per <a href=\"https://nces.ed.gov/programs/digest/d15/tables/dt15_105.20.asp\">2015 enrolment estimates from the NCES.</a>{/ref}</p>\n\n\n\n<p>This is the result of a process of education expansion that relied heavily on public funding, particularly from local governments. The visualization shows the sources of revenues for public schools in the US over the last 120 years. As it can be seen, states and localities are \u2013 and have always been \u2013 the main sources of funding for public primary education in the US. In fact, we observe three broad periods in this graph: there is first a period of stable revenues until 1920, then a period of sharp growth and decline during the interwar years, and then a period of substantial growth since the second world war, slowing down in the 1970s. In all these periods, federal funding was always very small, as can be seen when changing the visualisation from ‘absolute’ to ‘relative’. Disaggregated data from the last couple of decades gives further insights into the specific sources of local revenues for schools in the US: the largest part comes from property taxes (about 80% of local revenues came from property taxes in 2013), while only a very small part comes from fees and donations (private funding for public schools, which is considered a local revenue, amounted to less than 2% of total public school revenues in 2013). This heavily decentralised system relying on property taxes has the potential of creating large inequalities in education, since public schools in affluent urban areas are able to raise more funding from local revenues. Indeed, a significant part of the debate on education inequalities in the US today focuses on the importance of increasing progressive federal spending to reduce inequalities in public school funding.{ref}A <a href=\"http://www.huffingtonpost.com/2015/03/13/arne-duncan-school-funding-disparities_n_6864866.html\">recent article from the Huffington Post</a> highlights this point, including interesting visualizations documenting the important role that federal funding plays in reducing expenditure inequalities.{/ref}</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/revenues-for-public-schools-by-source-us\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>How did France finance the expansion of public education?</h4>\n\n\n\n<p>The case of the US above shows that funding for public schools has been historically a responsibility of local governments. In other countries, such as France, the expansion of public education also took place initially with resources from local governments, but relatively quickly the fiscal burden was shifted to the national level. In France this transition was associated with a sharp jump towards universal access and a concomitant reduction in regional inequalities. The following visualization from Lindert (2004){ref}Lindert, Peter H. <em>Growing public: Volume 1, the story: Social spending and economic growth since the eighteenth century</em>. Vol. 1. Cambridge University Press, 2004.{/ref} provides evidence of the French experience. As we can see there are three distinct periods: education spending was initially low and mainly private, then in 1833 funding began growing with local resources after the introduction of a law liberating communes to raise more local taxes for schools, and finally in 1881 the national government took over most of the financial responsibility after the introduction of a new law that abolished all fees and tuition charges in public elementary schools. In the source book, Lindert (2004) provides further evidence of how this transition towards centrally funded public education reduced north-south inequalities in France.</p>\n\n\n\n<h6>Sources of funds for France\u2019s public primary schools, 1820\u20131913 \u2013 Figure 5.5 in Lindert (2004){ref}Lindert, Peter H. <em>Growing public: Volume 1, the story: Social spending and economic growth since the eighteenth century</em>.

The following graph does this using data from the National Center for Education Statistics in the US. It shows that during the years 1950-1970 \u2013 a period of substantial growth in education expenditure in the US \u2013 expenditure grew <em>specifically</em> in the public sector.{ref}Bear in mind that the estimates from the National Center for Education Statistics are not broken down by source of funds. Rather, they show expenditure by type of institution \u2013 which is not equivalent, since public institutions may spend private resources, and vice versa.{/ref}</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/us-education-expenditure-as-share-of-gdp-public-and-private\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>When did the expansion of basic education become a global phenomenon?</h4>\n\n\n\n<p>The second half of the 20th century marked the beginning of education expansion as a global phenomenon. The visualization, using data from Szirmai (2005){ref} Szirmai, A. (2005) The Dynamics of Socio-Economic Development: An Introduction. Cambridge University Press. {/ref}, shows government expenditure on education as a share of national income for a selection of low and middle-income countries, together with the corresponding average for high-income countries, for the period 1960-2010. As it can be seen, by 1990 government spending on education in many developing countries was already close to the average observed in developed countries.</p>\n\n\n\n<p>It is important to point out that the remark above makes reference to convergence in expenditure relative to <em>income</em>. To the extent that low-income countries remain poorer than high-income countries, gaps in levels of expenditure per pupil are persistently large. Indeed, cross-country heterogeneity in education expenditure per pupil is currently much higher than heterogeneity in expenditure as share of GDP.{ref}In 2010, high income countries spent 6721 US PPP dollars per primary school pupil. Low income countries, in contrast, spent 115 US PPP dollars per pupil (UNESCO EFA Global Monitoring Report 2014). {/ref} One factor contributing to the slower convergence of expenditure per pupil in real terms is the fact that teachers’ salaries \u2013 <a href=\"https://ourworldindata.org/financing-education#where-does-funding-for-education-go-to\">the main component of education expenditure</a> \u2013 are much higher in high-income countries, because labour has a higher opportunity cost in these countries. In general, the opportunity cost of labour is a key variable that governments in developing countries should factor in when deciding whether to expand education now, rather than later.</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/share-of-education-in-government-expenditure\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>Education inequality is falling around the world</h4>\n\n\n\n<p>An important consequence of the global education expansion is a reduction in education inequality across the globe. The following visualization shows this through a series of graphs plotting changes in the Gini coefficient of the distribution of years of schooling across different world regions. The Gini coefficient is a measure of inequality and higher values indicate higher inequality \u2013 you can read about the definition and estimation of Gini coefficients in our entry on <a href=\"https://ourworldindata.org/income-inequality/#the-gini-coefficient\">income inequality</a>. The time-series chart shows inequality by age group. It can be seen that as inequality is falling over time, the level of inequality is higher for older generations than it is for younger generations. We can also see that in the reference period education inequality went down every year, for all age groups and in all world regions.</p>\n\n\n\n<p>Have gains from historical education expansion fully materialized? The breakdown by age gives us a view into the future: as the inequality is lower among today’s younger generations, we can expect the decline of inequality to continue in the future. Thus, further reductions in education inequality are still to be expected within developing countries; and if the expansion of global education can be continued, we can speed up this important process of global convergence.</p>\n\n\n\n<h6>Education Gini coefficients by world region for selected age groups, 1960- 2010 \u2013 Figure 4 in Crespo Cuaresma et al.

The following visualization show two graphs comparing the concentration of years of education in South Korean between the years 1970 and 2010. To be precise, each of these graphs shows an education Lorenz curve: a plot showing the cumulative percentage of the schooling years across all levels of education on the vertical axis, and the cumulative percentage of the population on the horizontal axis. As it can be seen, in 2010 education was much less concentrated than in 1970, not only because there was a smaller share of individuals without schooling (shown along the bottom of the chart), but also because there was a smaller share of individuals concentrating large proportions of school-years at higher levels of education. Indeed, in only 40 years South Korea was able to double the mean years of schooling (from 6 to 12 years) and at the same time get remarkably close to the 45-degree line marking the hypothetical scenario of perfect equality of schooling. In other entries we show that in this same period South Korea increased drastically its <a href=\"https://ourworldindata.org/gdp-growth-over-the-last-centuries/#real-gdp-per-capita-around-the-world-ppp-adjusted-since-1000-max-roserref\"> GDP per capita</a> while significantly improving health outcomes, such as <a href=\"https://ourworldindata.org/grapher/child-mortality?country=KOR\">child mortality</a>.</p>\n\n\n\n<h6>Inequality of Educational Attainment in South Korea 1970 and 2010{ref}Data from Petra Sauer (2016) \u2013 The Role of Age and Gender in Education Expansion.

The following chart plots trends in public expenditure on education as a share of GDP. As usual, a selection of countries is shown by default, but other countries can be added by clicking on the relevant option at the top of the chart. Although the data is highly irregular due to missing observations for many countries \u2013 an issue we discuss in more detail in our section on Data Quality below \u2013, we can still observe a broad upward trend for the majority of countries. Specifically, it can be checked that of the 88 countries with available data for 2000/2010, three-fourths increased education spending as a share of GDP within this decade. As incomes \u2013 measured by GDP per capita \u2013 are generally increasing around the world, this means that the total amount of global resources spent on education is also increasing in absolute terms.</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/total-government-expenditure-on-education-gdp\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<p>You can explore the trends by education level in these interactive charts:</p>\n\n\n\n<ul><li><a href=\"https://ourworldindata.org/grapher/government-expenditure-on-pre-primary-education-as-share-of-gdp\" target=\"_blank\" rel=\"noopener noreferrer\">Government expenditure on pre-primary education as share of GDP</a></li><li><a href=\"https://ourworldindata.org/grapher/government-expenditure-on-primary-education-as-share-of-gdp\" target=\"_blank\" rel=\"noopener noreferrer\">Government expenditure on primary education as share of GDP</a></li><li><a href=\"https://ourworldindata.org/grapher/government-expenditure-on-secondary-education-as-share-of-gdp\" target=\"_blank\" rel=\"noopener noreferrer\">Government expenditure on secondary education as share of GDP</a></li><li><a href=\"https://ourworldindata.org/grapher/government-expenditure-on-tertiary-education-as-share-of-gdp\" target=\"_blank\" rel=\"noopener noreferrer\">Government expenditure on tertiary education as share of GDP</a></li></ul>\n\n\n\n<h4>Is additional funding for education taking resources from other sectors?</h4>\n\n\n\n<p>The above-mentioned growth in overall government expenditure on education as a share of GDP cannot be entirely attributed to a wide-spread change in the prioritization of education spending within domestic budgets. The following visualization shows government expenditure on education as a share of total government expenditure. In this case the available data does not suggest a discernible global pattern. For instance, of the 36 countries with available data for 2000 to 2010, only around half increased spending on education relative to the other sectors. The data does suggest, however, that there is large and persistent cross-country heterogeneity in the relative importance of education vis-a-vis other sectors, even within developing countries. For example, in 2011 education accounted for about 8% of government spending in the Central African Republic, while it accounted for about 30% in Ghana.</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/share-of-education-in-government-expenditure\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>European countries tend to assign a lower share of public budgets to education, relative to the amount of their income that is devoted to education</h4>\n\n\n\n<p>Generally speaking, countries that spend a large share of their income on education also tend to prioritize education highly within their budgets. The following visualization presents a snapshot of government spending on education around the world for the year 2016. Specifically, this graph plots government expenditure on education as a share of GDP in the vertical axis, and government expenditure on education as a share of total government expenditure in the horizontal axis. Each dot on this chart represents a different country, with the assigned colors denoting different world regions. As we can see, there is a positive correlation, but regional differences are stark: for almost every level of spending as a share of GDP along the horizontal axis, European countries (marked in light orange) spend a smaller budget share on education.</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/share-edu-spending-gdp-vs-share-edu-total-spending\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>In European countries the weight of primary education within total education spending is lower than in other countries</h4>\n\n\n\n<p>In comparison to countries where education started expanding later, European countries tend to assign relatively more of their government education budgets to the secondary and tertiary levels, while at the same time devoting relatively less of their general government budgets to education as a whole. This can be appreciated in the following visualization, where the priorization of primary education (i.e. the share of primary education within the education budget) is plotted against the overall priorization of education (i.e. the share of education within the entire government budget). It can be seen that European countries (marked again in light orange) are mostly located in the bottom-left. And there is a weak positive correlation between the variables, both across all countries and across European countries.{ref}For reference, the correlation for all countries in this scatter plot is 0.24.{/ref}</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/primary-edu-spending-vs-overall-edu-spending\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>In high-income countries households shoulder a larger share of education expenditures at higher education levels than at lower levels \u2013 but in low-income countries this is not the case</h4>\n\n\n\n<p>The following visualization shows the percentage of total education expenditures contributed directly by households in 15 high income countries and 15 low/middle income countries (most recent data available on 2014). The top chart in this figure, corresponding to high income countries, shows a very clear pattern: households contribute the largest share of expenses in tertiary education, and the smallest share in primary education. Roughly speaking, this pattern tends to be progressive, since students from wealthier households are more likely to attend tertiary education, and those individuals who attend tertiary education are likely to perceive large private benefits (more on this in our entry on <a href=\"https://ourworldindata.org/skill-premium-income-by-education/\">Skill Premium</a>).{ref}Strictly speaking, for this spending pattern to be truly progressive there must be subsidies or income-contingent loans to guarantee that low-income students can also access tertiary education and reap the private benefits from this type of investment.{/ref} In contrast, the bottom chart shows a very different picture: in several low-income countries households contribute proportionally more to primary education than to higher levels. Malawi is a notable case in point \u2013 tertiary education is almost completely subsidised by the state, yet household contribute with almost 20% of the costs in primary education. Such distribution of private household contributions to education is regressive.</p>\n\n\n\n<h6>Percentage of total education expenditures contributed directly by households in 30 countries, grouped by country income \u2013 Figure 32 in <a href=\"http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf\">The Investment Case for Education and Equity (UNICEF – 2015)</a></h6>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https://ourworldindata.org/app/uploads/2016/06/UNICEF-Private-Education-Expenditure-Levels.png\"><img loading=\"lazy\" width=\"440\" height=\"550\" src=\"https://ourworldindata.org/app/uploads/2016/06/UNICEF-Private-Education-Expenditure-Levels-440x550.png\" alt=\"UNICEF Private Education Expenditure Levels\" class=\"wp-image-8145\" srcset=\"https://owid.cloud/app/uploads/2016/06/UNICEF-Private-Education-Expenditure-Levels-440x550.png 440w, https://owid.cloud/app/uploads/2016/06/UNICEF-Private-Education-Expenditure-Levels-120x150.png 120w, https://owid.cloud/app/uploads/2016/06/UNICEF-Private-Education-Expenditure-Levels-320x400.png 320w, https://owid.cloud/app/uploads/2016/06/UNICEF-Private-Education-Expenditure-Levels-768x961.png 768w, https://owid.cloud/app/uploads/2016/06/UNICEF-Private-Education-Expenditure-Levels.png 1664w\" sizes=\"(max-width: 440px) 100vw, 440px\" /></a></figure></div>\n\n\n\n<h2>Recent funding structures in OECD countries</h2>\n\n\n\n<h4>Primary education continues to be publicly funded in industrialized countries</h4>\n\n\n\n<p>We have already mentioned that those countries that pioneered the expansion of primary education in the 19th century \u2013 all of which are current OECD member states \u2013 relied heavily on public funding to do so. Today, public resources still dominate funding for the primary, secondary and post-secondary non-tertiary education levels in these countries. While in the last decade the share of public funding for these levels of education has decreased slightly, the broad pattern is remarkably stable. The visualization presents OECD-average expenditure on education institutions by source of funds.{ref}The OECD provides country-specific figures. However, there is relatively little variation across OECD countries in this respect. This is explained by near-universal enrolment rates at these levels of education and the demographic structure of the population.{/ref} By clicking on the option labeled ‘relative’ you can see the corresponding share of each source: private funding went up from 7.9% in 2000, to 9.4% in 2012. The role of public funding for other levels of education is however quite different. At the tertiary level public sources account for less than 70% of funding on average (2012 figures). Below we provide evidence of the pre-school level.</p>\n\n\n\n<figure><iframe loading=\"lazy\" style=\"width: 100%; height: 600px; border: 0px none;\" src=\"https://ourworldindata.org/grapher/average-oecd-education-expenditure-by-source-of-funding-gdp\" width=\"300\" height=\"150\"></iframe></figure>\n\n\n\n<h4>Publicly funded pre-primary education is more strongly developed in the European countries of the OECD</h4>\n\n\n\n<p>High-income countries tend to have better developed pre-primary education systems than lower-income countries. However, within high-income countries there is substantial heterogeneity in the extent to which pre-primary education is publicly financed. The visualization presents expenditure on pre-primary educational institutions as a share of GDP across the OECD. As it can be seen, publicly funded pre-primary education tends to be more strongly developed in the European than the non-European countries of the OECD. In fact, the OECD reports that in Europe the concept of universal access to education for 3-6 year-olds is generally accepted: most countries in this region provide all children with at least two years of free, publicly funded pre-primary education in schools before they begin primary education.</p>\n\n\n\n<h6>Expenditure on pre-primary educational institutions (% of GDP), OECD, 2012 \u2013 Figure C2.4 in <a href=\"http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1\">Education at a Glance (2015)</a></h6>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https://ourworldindata.org/app/uploads/2016/06/OECD_Expenditure_Pre-primary.png\"><img loading=\"lazy\" width=\"750\" height=\"301\" src=\"https://ourworldindata.org/app/uploads/2016/06/OECD_Expenditure_Pre-primary-750x301.png\" alt=\"OECD_Expenditure_Pre-primary\" class=\"wp-image-8074\" srcset=\"https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Pre-primary-750x301.png 750w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Pre-primary-150x60.png 150w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Pre-primary-400x161.png 400w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Pre-primary-768x309.png 768w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Pre-primary.png 1906w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></a></figure></div>\n\n\n\n<h4>Where does funding for education go to?</h4>\n\n\n\n<p>The largest part of funding devoted to education in OECD countries goes to finance current expenditures, mainly compensation of staff \u2013 specifically, teachers. The following two charts, taken from the OECD’s report <a href=\"http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1\">Education at a Glance (2015)</a>, highlight the labour-intensive nature of education. In the lower levels of education (i.e. primary, secondary and post-secondary non-tertiary) the share of current expenditure is very large and exhibits little cross-country variation \u2013 between 90 and 97 percent of total expenditure corresponds to current expenditure across all of the OECD countries. In higher levels of education (i.e. tertiary) there is more cross-country variation, but current expenditure still dominates by a large margin across all countries.</p>\n\n\n\n<h6>Distribution of current and capital expenditure on educational institutions \u2013 Figure B6.2 in <a href=\"http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1\">Education at a Glance (2015)</a></h6>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https://ourworldindata.org/app/uploads/2016/06/OECD_Expenditure_Education_Resources-.png\"><img loading=\"lazy\" width=\"663\" height=\"550\" src=\"https://ourworldindata.org/app/uploads/2016/06/OECD_Expenditure_Education_Resources--663x550.png\" alt=\"OECD_Expenditure_Education_Resources\" class=\"wp-image-8065\" srcset=\"https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Education_Resources--663x550.png 663w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Education_Resources--150x124.png 150w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Education_Resources--400x332.png 400w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Education_Resources--768x637.png 768w, https://owid.cloud/app/uploads/2016/06/OECD_Expenditure_Education_Resources-.png 1928w\" sizes=\"(max-width: 663px) 100vw, 663px\" /></a></figure></div>\n\n\n\n<h4>What drives current expenditure on education?</h4>\n\n\n\n<p>In the figures above we noted the importance of current expenditure in the production of education. The following table provides further details regarding the type of expenditures that comprise current spending. Specifically, this chart shows a breakdown of expenditure for tertiary-level institutions in the US (public and private), during the period 1980-1997. It shows that instruction accounts for almost half of expenditure; and while there are some small differences across sectors, there is a fair amount of stability in expenditures across time. This serves as a benchmark for lower education levels, where instruction takes an even larger share of expenditure.{ref}This is a stylized fact of OECD education spending. In all the OECD countries, the share of spending devoted to compensation of teachers is by far the largest component of current expenditure. Moreover, expenditure on teachers’ compensation is larger at the combined primary, secondary and post-secondary non-tertiary levels of education than at the tertiary level.

The following chart shows total OECD development assistance flows for education by level, in constant 2013 US dollars, for the period 2002-2013. As it can be seen, there are two distinct periods: in 2003-2010 flows for education increased substantially, more than doubling in real terms across all levels of education; and in the years 2010-2013 funding for basic education <em>decreased</em>, while funding for secondary and post-secondary education remained relatively constant. For many low income countries, where development assistance contributes a substantial share of funding for education, this marked change in trends is important. As a reference, in 2012 development assistance accounted for more than 20 percent of all domestic spending on basic education in recipient low-income countries.{ref}Steer L. and K.

Specifically, the share of development assistance for primary education going to sub-Saharan Africa has been decreasing sharply since the agreement of the Millennium Development Goals. The following chart shows this: sub-Saharan Africa\u2019s share in total aid to primary education declined from 52 percent in 2002 to 30 percent in 2013, while the continent\u2019s share in the total number of out-of-school children rose from 46 percent to 57 percent. This pattern is something specific to the education sector within the broader development assistance landscape: in the healthcare sector the overall slowdown of flows started a couple of years later, was less abrupt, and affected proportionally less the sub-Saharan countries.{ref}The share of development assistance going to sub-Saharan Africa has decreased as a whole \u2013 from 55 percent in 2002 to 40 percent in 2013 \u2013, but as we note the drop specifically for primary education has been steeper.{/ref} Indeed, recent studies further highlight that development assistance for education is significantly different to assistance for healthcare in other ways: the education sector attracts less earmarked funding through multilaterals, and includes a smaller proportion of resources that developing governments can directly control for programming.{ref}Steer L. and K.

But for any given country, with a determined income distribution and demographic structure, the extent to which public spending on education contributes to reduce inequality depends crucially on the way in which spending is focused across education levels. The recent UNICEF report <a href=\"http://www.unicef.org/publications/files/Investment_Case_for_Education_and_Equity_FINAL.pdf\">The Investment Case for Education and Equity</a> shows that in low income countries, on average 46 percent of public resources are allocated to the 10 percent of students who are most educated \u2013 while this figure goes down to 26 and 13 percent in lower-middle and upper-middle income countries respectively. The following visualization shows further details on the concentration of public spending across different countries. The vertical axis shows the percentage of public education resources going to the 10% most educated or 10% least educated students \u2013 as we can see expenditure is heavily concentrated at the top in many low income countries.</p>\n\n\n\n<p>The earlier remarks about trends in international education financing flows (namely that aid is very important in low-income countries, and that a relatively low and shrinking share of aid is going to primary levels), suggest that inequality in public spending will worsen in low income countries. Yet development assistance priorities have a scope for changing this.{ref}The conclusion from these figures is that, while public spending does reduce education inequality in low income countries, remaining inequalities could be further reduced by shifting resources towards lower levels of education. This evidently does not mean that resources <em>should</em> be shifted \u2013 low income countries and aid donors may have other objectives apart from reducing inequality. But the case for reducing inequality at the bottom is very strong, and some studies suggest that returns to education at the primary level might be higher than at post-primary levels in low income countries (for a discussion of the vast literature on returns to education, and the ongoing debate on the validity of estimates, see Heckman, J. J., Lochner, L. J., & Todd, P. E. (2006). Earnings functions, rates of return and treatment effects: The Mincer equation and beyond.

The logic is that individuals may not spend enough on education because they fail to internalize the positive effect that their education has on other people. But there are, of course, also equity arguments to justify government intervention in the provision of education \u2013 for instance, reducing inequality in education may be of intrinsic value, or may be instrumental in reducing inequalities in other outcomes.{/ref} This essentially means that investing in education yields both private and social returns. Private returns to education include higher wages and better employment prospects. Social return include pro-social behaviour (e.g. volunteering, political participation) and interpersonal <a href=\"https://ourworldindata.org/trust/\">trust</a>. The following chart uses OECD results from the Survey of Adult Skills to show how self-reported trust in others correlates with educational attainment. More precisely, this chart plots the percentage-point difference in the likelihood of reporting to trust others, by education level of respondents. Those individuals with upper secondary or post-secondary non-tertiary education are taken as the reference group, so the percentage point difference is expressed in relation to this group. As we can see, in all countries those individuals with tertiary education were by far the group most likely to report trusting others. And in almost every country, those with post-secondary non-tertiary education were more likely to trust others than those with primary or lower secondary education. The OECD’s report <a href=\"http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1\">Education at a Glance (2015)</a> provides similar descriptive evidence for other social outcomes. The conclusion is that adults with higher qualifications are more likely to report desirable social outcomes, including good or excellent health, participation in volunteer activities, interpersonal trust, and political efficacy. And these results hold after controlling for literacy, gender, age and monthly earnings.</p>\n\n\n\n<h6>Likelihood of reporting to trust others, by educational attainment, OECD 2012 \u2013 Figure A8.4 in <a href=\"http://www.keepeek.com/Digital-Asset-Management/oecd/education/education-at-a-glance-2015_eag-2015-en#page1\">Education at a Glance (2015)</a>{ref}As per the source notes: “Percentage-point difference reflects the relative change of reporting to trust others compared to the reference category. For example, in Norway, the percentage of individuals with tertiary education reporting to trust others increases by 20 percentage points compared to someone who has upper secondary or post-secondary non-tertiary education. Similarly, after accounting for literacy proficiency, the percentage of individuals with tertiary education increases by 16 percentage points compared to someone who has upper secondary or post-secondary non-tertiary education.”{/ref}</h6>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https://ourworldindata.org/app/uploads/2016/06/OECD_Education_Trust.png\"><img loading=\"lazy\" width=\"750\" height=\"441\" src=\"https://ourworldindata.org/app/uploads/2016/06/OECD_Education_Trust-750x441.png\" alt=\"OECD_Education_Trust\" class=\"wp-image-8134\" srcset=\"https://owid.cloud/app/uploads/2016/06/OECD_Education_Trust-750x441.png 750w, https://owid.cloud/app/uploads/2016/06/OECD_Education_Trust-150x88.png 150w, https://owid.cloud/app/uploads/2016/06/OECD_Education_Trust-400x235.png 400w, https://owid.cloud/app/uploads/2016/06/OECD_Education_Trust-768x451.png 768w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></a></figure></div>\n\n\n\n<h4>Do countries that spend more public resources on education tend to have better education outcomes?</h4>\n\n\n\n<p>Education outcomes are typically measured via ‘quantity’ output (e.g. years of schooling) and <a href=\"https://ourworldindata.org/quality-of-education\">‘quality’ output</a> (e.g. learning outcomes, such as test scores from the Programme for International Student Assessment \u2013 PISA). The following visualization presents three scatter plots using 2010 data to show the cross-country correlation between (i) education expenditure (as a share of GDP), (ii) mean years of schooling, and (iii) mean PISA test scores. At a cross-sectional level, expenditure on education correlates positively with both quantity and quality measures; and not surprisingly, the quality and quantity measures also correlate positively with each-other. But obviously correlation does not imply causation: there are many factors that simultaneously affect education spending and outcomes. Indeed, these scatterplots show that despite the broad positive correlation, there is substantial dispersion away from the trend line \u2013 in other words, there is substantial variation in outcomes that does not seem to be captured by differences in expenditure. </p>\n\n\n\n<h6>Correlation between education outcomes and education expenditure (2010 data){ref}Data on expenditure corresponds to 2010 total government education expenditure across all levels, as a share of GDP (source: World Bank Education Statistics).

Borrowing the terms from the economics literature, the following \u2018production function\u2019 provides a conceptual framework to think about the determinants of learning outcomes{ref}P. Glewwe, K. Muralidharan (2016). <em><a href=\"https://www.sciencedirect.com/science/article/pii/B9780444634597000105\">Improving Education Outcomes in Developing Countries: Evidence, Knowledge Gaps, and Policy Implications</a></em>. Handbook of the Economics of Education, Volume 5.{/ref}:</p>\n\n\n<p>[latex]A=a(s,\\mathbf{Q},\\mathbf{C},\\mathbf{H},\\mathbf{I})[/latex]</p>\n\n\n\n<p>where <em>A</em> is skills learned (achievement), <em>s</em> is years of schooling, <strong>Q</strong> is a vector of school and teacher characteristics (quality), <strong>C</strong> is a vector of child characteristics (including “innate ability”), <strong>H</strong> is a vector of household characteristics, and <strong>I</strong> is a vector of school inputs under the control of households, such as children\u2019s daily attendance, effort in school and in doing homework, and purchases of school supplies.</p>\n\n\n\n<p>This conceptualization highlights that, for any given level of expenditure, the output achieved will depend on the input mix. And consequently, this implies that in order to explain education outcomes, we must rely on information about specific inputs. In the following sections we explore evidence regarding the returns to household inputs (i.e. different elements of <strong>Q</strong>) and demand-side inputs (i.e. elements of <strong>C,H</strong> and <strong>I</strong>).</p>\n\n\n\n<h3>School inputs</h3>\n\n\n\n<h4>Each education system is different, but improving teacher quality is often more effective to improve learning outcomes than increasing the number of teachers per pupil</h4>\n\n\n\n<p>A vast number of studies have tried to estimate the impact of classroom resources on learning outcomes. The following table summarizes results from the systematic review in Hanushek (2006){ref}Hanushek, E. A., (2006). School Resources. Handbook of the Economics of Education, Volume 2. Elsevier.{/ref}. In this table, the left-hand side summarizes results from econometric studies focusing on developing countries, while the right-hand side presents evidence from the US (where studies have concentrated extensively). We can see that for all listed inputs and across all countries, the share of studies that have found a positive effect is small \u2013 in fact, the majority of studies find either no effect, or a negative effect. This clearly does not mean that these classroom resources are not important, but rather that it is very difficult to know with confidence when and where they are a binding constraint to improve learning outcomes. A first conclusion, therefore, seems to be that context and input mix are fundamental to improving outcomes \u2013 even in developing countries where the expected returns to additional resources is large across the board.</p>\n\n\n\n<p>Taking the ratio of positive to negative effects detected in the literature as a proxy for what tends to work best, we can derive a second conclusion from the table: spending more resources on better teachers (i.e. improving teacher experience and teacher education) tends to work better to improve learning outcomes than simply increasing the number of teachers per pupil. And this seems to be true both in developed and developing countries. This last conclusion is consistent with the main message from the OECD’s report <a href=\"http://www.oecd.org/pisa/pisaproducts/pisainfocus/49685503.pdf\">Does money buy strong performance in PISA?</a>, which points out that countries that prioritised the quality of teachers over class sizes performed better in PISA tests.{ref} This claim is clearly only descriptive, since there are many underlying variables that simultaneously drive teacher characteristics and student outcomes in any particular country. Indeed, most of the available evidence on whether teacher quality and quantity matters is difficult to interpret causally, as it is hard to find instances where teacher quality / quantity varies exogenously. A recent study concludes on the topic: <em> “teachers vary in many ways, but we found no high-quality studies that have examined the impact of teacher characteristics on student learning or time in school” </em>(source: page 696, Glewwe, P. and Muralidharan, K.

Handbook of the Economics of Education, Volume 5. ) {/ref}</p>\n\n\n\n<p> And it is also consistent with a recent high-quality study on the impact of teacher quality on test scores using data from the US, which suggests that improvements in teacher quality can causally raise students\u2019 test scores (evidence from Chetty et al. (2014){ref}Chetty, Raj, John N. Friedman, and Jonah E.

Recent evidence from policy ‘experiments’ in developing countries suggests remedial teaching, in the form of assistants teaching targeted lessons to the bottom of the class, can yield substantial improvements in learning outcomes. The following visualization summarizes the effects of four different policy treatments within the so-called Teacher Community Assistant Initiative (TCAI) in Ghana \u2013 this is an initiative that evaluated four different such remedial teaching interventions.{ref}Further details in Innovations for Poverty Action, 2014. Implementation Lessons: The Teacher Community Assistant Initiative (TCAI). Available online from <a href=\"http://www.poverty-action.org/sites/default/files/publications/TCAI_Final%20Results_040115.pdf\">www.poverty-action.org</a> {/ref}</p>\n\n\n\n<p>The units in this figure are standard deviations of test results. The first two sets of estimates correspond to the test-score impacts of enabling community assistants to provide remedial instruction specifically to low-performing children, either during school, or after school. The third set of estimates corresponds to test-score impacts of providing a community assistant and reducing class size, without targeting instruction to low-performing pupils. And the last set of results corresponds to testing the effect of training teachers to provide small-group instruction targeted at pupils\u2019 actual learning levels.</p>\n\n\n\n<p>As we can see, while all interventions had a positive effect, the lowest impacts \u2013 across all tests \u2013 come from the non-targeted ‘normal curriculum’ intervention that reduced class sizes, and from the intervention that provided training to teachers on how to engage in targeted remedial teaching themselves. This suggests that the improvements in outcomes were caused by the combination of targeted instruction and TCAs who, unlike teachers, were specifically dedicated to this purpose. These results are consistent with findings from across Africa, suggesting that teaching at the right level causes better learning outcomes in a cost-effective way (see Glewwe and Muralidharan 2016{ref}Glewwe, P. and Muralidharan, K.

And we have also pointed out that improving teacher quality may be a particularly good instrument to improve teaching outcomes. This leads to a natural question: are pay-for-performance teacher contracts an effective instrument to improve learning outcomes? A growing body of literature in the economics of education has started using randomized control trials (i.e. policy ‘experiments’) to answer this question. Glewwe and Muralidharan (2016){ref}Glewwe, P. and Muralidharan, K. (2016) <a href=\"https://www.sciencedirect.com/science/article/pii/B9780444634597000105\">Improving Education Outcomes in Developing Countries: Evidence, Knowledge Gaps, and Policy Implications</a>. Handbook of the Economics of Education, Volume 5. Elsevier. (Link only to working paper){/ref} provide the following account of the available evidence:</p>\n\n\n\n<blockquote class=\"wp-block-quote\"><p><em>“Results suggest that even modest changes to compensation structures to reward teachers on the basis of objective measures of performance (such as attendance or increases in student test scores) can generate substantial improvements in learning outcomes at a fraction of the cost of a “business as usual” expansion in education spending. However, not all performance pay programs are likely to be effective, so it is quite important to design the bonus formulae well and to make sure that these designs reflect insights from economic theory.”</em> {ref}Glewwe, P. and Muralidharan, K. (2016) <a href=\"https://www.sciencedirect.com/science/article/pii/B9780444634597000105\">Improving Education Outcomes in Developing Countries: Evidence, Knowledge Gaps, and Policy Implications</a>. Handbook of the Economics of Education, Volume 5. Elsevier. (Link only to working paper){/ref}</p></blockquote>\n\n\n\n<p>The conclusion is that well-designed pay-for-performance contracts are a cost-effective instrument to boost test scores; but this does not mean that they are necessarily effective at achieving other \u2013 perhaps equally important \u2013 objectives of time spent in school. In simple words, it is possible that pay-for-performance yields ‘teaching to the test’. Alternative incentive mechanisms, such as community-based monitoring of teachers, have been proposed as an alternative. Glewwe and Muralidharan (2016) also provide a review of the \u2013 somewhat limited \u2013 available evidence on such alternative incentive mechanisms.{ref}They conclude that “evidence on the impact of monitoring on time in school is scarce and not encouraging…[while] the evidence of the impact of monitoring on student learning is only somewhat more encouraging”{/ref}</p>\n\n\n\n<h3>Household inputs</h3>\n\n\n\n<h4>School attendance and student effort are responsive to incentives</h4>\n\n\n\n<p>Demand-side inputs are as important as supply-side inputs to produce education. Attending school and exerting effort are perhaps the most obvious examples: without these inputs even the best endowed schools will fail to deliver good outcomes. The table summarizes information on different demand-side investments that have shown to successfully improve quality and quantity outcomes. More precisely, this table gathers evidence from randomized control trials in developing countries, as per the review in Glewwe and Muralidharan (2016). The reported figures correspond to positive/negative significant/insignificant estimates across a set of available experimental studies (bear in mind some studies estimate more than one effect \u2013 e.g. by measuring outcomes at several points in time). As we can see, the evidence suggests interventions that increase the benefits of attending school \u2013 such as conditional cash transfers \u2013 are likely to increase student time in school. And those that increase the benefits of higher effort and better academic performance \u2013 such as merit scholarships \u2013 are likely to improve learning outcomes (see Glewwe and Muralidharan 2016 for further details on the underlying policy interventions, plus further evidence and discussion of results).</p>\n\n\n\n<h6>Summary of impacts for selected demand-side interventions on education outcomes in developing countries \u2013 based on Tables 4 and 5 from Glewwe and Muralidharan (2016){ref}Glewwe, P. and Muralidharan, K.

The following visualization presents a comparison of the impact that a number of different health interventions have achieved in different countries \u2013 together with some non-health-related interventions that serve as reference. The height of each bar in this graph reflects the additional school years achieved per hundred dollars spent on the corresponding intervention; so these estimates can be interpreted as a measure of how cost-effective the different interventions are.{ref}Bear in mind that the reported gains in school years are a measure of the <em>total</em> impact of the program across the treated population, rather than impact per treated student. Further information on cost-effectiveness analysis is available from the source of the graph.{/ref}</p>\n\n\n\n<p>We see that treating children for intestinal worms (labeled ‘deworming’ in the chart) led to an additional 13.9 years of education for every $100 spent in Kenya; while a program targeting anaemia (labeled ‘iron fortification’) led to 2.7 additional years per $100 in India. These interventions seem to be much more cost-effective to improve test scores than conditional cash transfers, free school uniforms, or merit scholarships (further details on all interventions available from Dhaliwal et al. 2012{ref}Dhaliwal, I., Duflo, E., Glennerster, R., & Tulloch, C.

Education Policy in Developing Countries, 285-338.{/ref}). Of course, ranking these interventions is not trivial since most programmes achieve multiple outcomes \u2013 indeed, we have already discussed that remedial teaching is generally effective to increase test-scores, although here we see a particular instance where it had no impact on school attendance. Nevertheless, health interventions seem to be particularly interesting, since they lead to substantial achievements in both education <em>and</em> health outcomes (for a recent analysis of the literature on the impacts of mass deworming see Croke et al. 2016{ref}Croke, Kevin, Joan Hamory Hicks, Eric Hsu, Michel Kremer, and Edward Miguel. 2016. \u201c<a href=\"http://scholar.harvard.edu/files/kremer/files/deworming-nber_2016-06-30.pdf\">Does Mass Deworming Affect Child Nutrition?

Cunha et al. (2006) provide a detailed account of the theory and evidence behind this claim, and discuss its implications for the design of education policies. In the chart we see the impacts from the Perry Preschool Program \u2013 a flagship experimental intervention study, designed to test the impact of pre-school education on subsequent education outcomes.{ref}More specifically, the Perry pre-school ‘experiment’ consisted in enrolling 65 randomly selected black children in a pre-school program, and comparing their outcomes later in life against those achieved by a control group of roughly the same size. The treatment consisted of a daily 2.5-hour classroom session on weekday mornings and a weekly 90-minute home visit by the teacher on weekday afternoons to involve the mother in the child’s educational process. More information and details on the intervention are available in Cunha et al. (2006).{/ref} The chart shows disadvantaged children participating in the pre-school program (the ‘treatment group’) had higher grades and were more likely to graduate from high school than the reference control group. Moreover, they spent substantially less time in special education. Other programs have similarly shown evidence of very large and persistent returns to early education interventions.</p>\n\n\n\n<h6>Educational effects from participating in the Perry Preschool Program \u2013 Figure 14B in Cunha et al (2006){ref}Cunha, F., Heckman, J.

The same data is also then published by the World Bank (<a href=\"http://datatopics.worldbank.org/education/\">World Bank EdStats</a> and <a href=\"http://databank.worldbank.org/data/reports.aspx?source=world-development-indicators\">World Development Indicators</a>) and <a href=\"https://www.gapminder.org\">Gapminder</a>. It is also the main source of education data for most UN reports \u2013 such as the EFA Global Monitoring Report (UNESCO), the Human Development Report (UNDP), the State of the World\u2019s Children report (UNICEF) and the Millennium Development Goals (UN).</p>\n\n\n\n<p>The UIS database is produced mainly from yearly national reports, but it also relies on reports from international organizations.{ref} The <a href=\"http://www.uis.unesco.org/Education/Documents/Background_information_on_education_statistics.pdf\">official documentation</a> says: “The UIS collects education statistics in aggregate form from official administrative sources at the national level. Collected information encompasses data on educational programmes, access, participation, progression, completion, literacy, educational attainment and human and financial resources. These statistics cover formal education in public (or state) and private institutions (pre-primary, primary, basic and secondary schools, and colleges, universities and other tertiary education institutions); and special needs education (both in regular and special schools)”.{/ref}</p>\n\n\n\n<p>Specifically, countries in the European Union, or members of the OECD, have richer data, since they collect information through the UIS-OECD-Eurostat (UOE) survey, which is more detailed than the UIS survey (see more at <a href=\"http://www.uis.unesco.org/Education/Pages/FAQ.aspx#sthash.hZOv7Ole.dpuf\">FAQ-UIS</a>)</p>\n\n\n\n<p>Another, related but different source of education expenditure data, is the International Food Policy Research Institute (IFPRI), which publishes the Statistics of Public Expenditure for Economic Development (SPEED). This source relies primarily on data from the International Monetary Fund (IMF).</p>\n\n\n\n<h3>Definitions</h3>\n\n\n\n<p>In the UIS database, government expenditure on education includes spending by local/municipal, regional and national governments, on public and private educational institutions, education administration, and subsidies for private entities (students/households and other privates entities). This information is then reported by level of education, and typically as a share of national income (GDP) or as a share of total public expenditure. In principle, expenditure on pre-primary levels as well as expenditure sourced with transfers from international sources to government, are included. In practice, however, many countries under report these specific figures.</p>\n\n\n\n<h3>Measurement limitations</h3>\n\n\n\n<p>The UIS has been maintained since 1999 with the intent of providing comparable expenditure figures across countries and time, and its estimates rely on reports submitted by ministries and national statistics offices. Since reporting is delegated typically to ministries of education, in some instances data on total public expenditure on education fails to represent spending by other ministries that also have budgets for education. Additionally, since not all countries have (or update) national education accounts, the UIS attempts to generate estimates and impute missing data using information from national publications, official websites and other sources. However, the UIS dataset has several missing observations, particularly for years prior to 2010.</p>\n\n\n\n<p>To gauge the extent to which UIS data is reliable, the following visualization shows the proportions of regular and irregular data that countries make available (where \u2018Regular\u2019 means data is available at least once every 3 years; and \u2018Irregular\u2019 means data is available less frequently than every 3 years). As can be seen, the picture is not particularly encouraging: less than half of the countries reported regularly data on total government expenditure on education over the reference period.</p>\n\n\n\n<h6>Availability of education financing data in the UIS database, 2005-2013, as a percentage of all (214) countries \u2013 Figure 1 in UNESCO\u2013UIS (2016){ref}UNESCO\u2013UIS (2016). A roadmap to better data on education financing. <a href=\"http://www.uis.unesco.org/Education/Documents/a-roadmap-to-better-data-on-education-financing.pdf\">INFORMATION PAPER NO. 27</a>.{/ref}</h6>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https://ourworldindata.org/app/uploads/2016/06/UIS-Data-Quality.png\"><img loading=\"lazy\" width=\"750\" height=\"513\" src=\"https://ourworldindata.org/app/uploads/2016/06/UIS-Data-Quality-750x513.png\" alt=\"UIS Data Quality\" class=\"wp-image-8149\" srcset=\"https://owid.cloud/app/uploads/2016/06/UIS-Data-Quality-750x513.png 750w, https://owid.cloud/app/uploads/2016/06/UIS-Data-Quality-150x103.png 150w, https://owid.cloud/app/uploads/2016/06/UIS-Data-Quality-400x273.png 400w, https://owid.cloud/app/uploads/2016/06/UIS-Data-Quality-768x525.png 768w, https://owid.cloud/app/uploads/2016/06/UIS-Data-Quality.png 1612w\" sizes=\"(max-width: 750px) 100vw, 750px\" /></a></figure></div>\n\n\n\n<p>Apart from the above-mentioned issues regarding the availability of data, comparing education financing between different countries can be challenging because the way that expenses are categorized is not always consistent. This can be particularly difficult when it comes to expenses that could potentially be classified as education or non-education-related, like teaching hospitals or transportation. While this issue is not as significant in other sectors like healthcare, it still presents some difficulties. For a further discussion of these issues see the <a href=\"http://www.uis.unesco.org/Library/Documents/UOE-data-collection-manual-formal-education-concepts-definitions-classifications-2015-en.pdf\">UIS data collection manual </a>.</p>\n\n\n\n<h2>Data Sources</h2>\n\n\n\n<h3>Long-run estimates of education financing</h3>\n\n\n\n<p>As it has been mentioned, the earliest data on financing of education dates back to the late 19th century, when today’s industrialized countries began expanding their education systems.
