Human Development Index (HDI)
WorldHuman Development Index scores, by country. HDI is a composite of life expectancy, education, and per capita income indicators, which are used to rank countries into four tiers of human development: very high, high, medium, and low. The rankings are viewed as the extent to which people are able to do things in life. HDI is a measure of the "potential" that people have to achieve economic and social goals, not necessarily whether all persons actually achieve such goals.
A world map shows the Human Development Index for different countries. Dark blue (more than 0.9): Canada, U S A. Blue to light blue (0.5 to 0.9): Brazil, Russia, north and South Africa. Very light blue (less than 0.5): most central countries of Africa.
