Human Development Indicators (UN)



HDIunHuman Development Indicators published annually by the United Nations Development Programme (UNDP), provide broad measures of well-being worldwide. There are three data dimensions: life expectancy, education, and purchasing power parity.

The UNDP also issues the annual Human Development Report.

In addition to the main Index, the UNDP issues three supplementary resources:

    • Inequality-adjusted HDI
    • Gender Inequality Index
    • Multidimensional Poverty Index.


Time period

Human Development Index data is available from 1990 to 2019.

Earlier Human Development Reports are available on the UNDP web site. The Badia Library holds a paper archive in storage.

How to access

Human Development data from 1990 to 2019 are available on the UNDP platform.

Data sources and methodology are explained on this UNDP page.

The UNDP provides the following explanation of the HDI data dimensions:

  • Life expectancy at birth: Number of years a newborn infant could expect to live if prevailing patterns of age-specific mortality rates at the time of birth remain the same throughout the infant's life
  • Mean years of schooling: Average number of years of education received by people ages 25 and older, converted from education attainment levels using official durations of each level
  • Expected years of schooling: Number of years of schooling that a child of school entrance age can expect to receive if prevailing patterns of age-specific enrolment rates persist throughout the child's life
  • Gross National Income (GNI) per capita: Aggregate income of an economy generated by its production and its ownership of factors of production, less the incomes paid for the use of factors of production owned by the rest of the world, converted to international dollars using purchasing power parity (PPP) rates, divided by mid-year population
  • Gross National Income per capita rank minus Human Development Index rank: Difference in rankings by GNI per capita and by the HDI. A negative value means that the country is better ranked by GNI than by the HDI
  • Non-income Human Development Index: Value of the HDI computed from the life expectancy and education indicators only.
