Human development index value
The human development index (HDI) is a composite index that measures the development of a country.
The HDI is based on qualitative and quantitative data:
- life expectancy at birth (which gives an idea of the health status of the population);
- the level of education measured by mean years of schooling and adult literacy rate;
- the GDP per capita in purchasing power parity (PPP) US dollars, giving an indication of the mean standard of living in the country.
The HDI is given as a number between 0 and 1. The closer it is to 1, the higher the level of development.
