Higher values indicate higher human development. The Human Development Index (HDI) is a summary measure of average achievement in key dimensions of human development: a long and healthy life, being knowledgeable and having a decent standard of living. The HDI is the geometric mean of normalized indices for each of the three dimensions. The health dimension is assessed by life expectancy at birth, the education dimension is measured by mean of years of schooling for adults aged 25 years and more and expected years of schooling for children of school entering age. The standard of living dimension is measured by gross national income per capita. The HDI uses the logarithm of income, to reflect the diminishing importance of income with increasing GNI. The scores for the three HDI dimension indices are then aggregated into a composite index using geometric mean. Refer to Technical notes for more details. The HDI can be used to question national policy choices, asking how two countries with the same level of GNI per capita can end up with different human development outcomes. These contrasts can stimulate debate about government policy priorities. The HDI simplifies and captures only part of what human development entails. It does not reflect on inequalities, poverty, human security, empowerment, etc. The HDRO provides other composite indices as broader proxy on some of the key issues of human development, inequality, gender disparity and poverty. A fuller picture of a country's level of human development requires analysis of other indicators and information presented in the HDR statistical annex.

    "Each of the dimensions of the HDI is measured with four indicators: a long and healthy life is measured by _life expectancy at birth_, good education (knowledge) is measured by two indicators, _expected_ and _mean_ _years of schooling_; and a decent standard of living is measured by _Gross National Income (GNI) per capita_, logarithmized to reflect that incomes become less important as they increase.",
    "The index is then calculated by normalizing and aggregating the indicators. First, the indicators are brought onto the same scale, ranging from 0 to 1. This is done by setting minimum and maximum values for each indicator, and a country at or below the minimum value receiving a score of 0, and a country at or above the maximum value receiving a score of 1.",
    "The minimum and maximum values for each indicator are defined as follows: _Life expectancy at birth_ ranges between 20 and 85 years; _expected years of schooling_ between 0 and 18 years; _mean years of schooling_, between 0 and 15 years; and _GNI per capita_ between 100 and 75,000 international-$ at 2017 prices.",
    "The HDI is then estimated as the geometric mean of these indices, or _HDI = (Health index * Education index * Income index)^(1/3)_. The education index is the arithmetic mean (average) of the mean years of schooling and expected years of schooling."
