List of countries by Human Development Index

This is a list of all the countries by the Human Development Index as included in a United Nations Development Programme's Human Development Report. The latest report was released on 14 December 2015 and compiled on the basis of estimates for 2014.

In the 2010 Human Development Report a further Inequality-adjusted Human Development Index (IHDI) was introduced. While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development (accounting for inequality)" and "the HDI can be viewed as an index of “potential” human development (or the maximum IHDI that could be achieved if there were no inequality)".

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. The index was developed in 1990 by Indian economist Amartya Sen and Pakistani economist Mahbub ul Haq The UN report covers 185 member states of the United Nations (out of 193), along with Hong Kong and the Palestinian territories; 8 UN member states are not included because of lack of data. The average HDI of regions of the World and groups of countries are also included for comparison.

Countries fall into four broad human development categories: Very High Human Development, High Human Development, Medium Human Development and Low Human Development.
