The Human Development Index (HDI) is a composite statistic of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development. A country scores higher if it performs better on these indicators.
The HDI was developed by the United Nations Development Programme (UNDP) in 1990 and is used to measure a country’s level of development. The HDI is based on the following three indicators:
- Life expectancy at birth: This indicator measures the average number of years that a person is expected to live.
- Education: This indicator measures the mean years of schooling for adults and the expected years of schooling for children.
- Per capita income: This indicator measures the gross national income (GNI) per capita, which is the total income of a country divided by its 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z"/> Subscribe on YouTube
