List of countries by Human Development Index


The United Nations Development Programme ranks countries into four tiers of human development by combining measurements of life expectancy, education, and per-capita income into the Human Development Index in its annual Human Development Report.
The HDI is a summary index using life expectancy at birth, expected years of schooling for children and mean years of schooling for adults, and GNI per capita. The final HDI is a value between 0 and 1 with countries grouped into four categories depending on the value, very high for HDI of 0.800 and above, high from 0.700 to 0.799, medium from 0.550 to 0.699 and low below 0.550.
The Human Development Report has been published most years since 1990. The 2019 report contained the HDI of 189 countries and territories and 15 regions or groups of countries based on data collected in 2018.
In the 2010 Human Development Report, a further Inequality-adjusted Human Development Index was introduced assessing countries on a fourth dimension of inequality. The report stated that while the HDI remains useful, "the IHDI is the actual level of human development " and "the HDI can be viewed as an index of 'potential' human development ".
