List of countries by Human Development Index
The Human Development Index (HDI) is a composite statistic of life expectancy, education, and income per capita indicators. A country scores higher HDI when the life expectancy at birth is longer, the education period is longer, and the income per capita is higher. It is used to distinguish whether the country is a developed, a developing or an underdeveloped country.
Countries fall into four broad human development categories: Very High Human Development, High Human Development, Medium Human Development and Low Human Development.
