What is the human development index (HDI)?

The HDI – human development index – is a summary composite index that measures a country's average achievements in three basic aspects of human development: health, knowledge, and a decent standard of living. Health is measured by life expectancy at birth; knowledge is measured by a combination of the adult literacy rate and the combined primary, secondary, and tertiary gross enrolment ratio; and standard of living by GDP per capita (PPP US$). For details on how to calculate the HDI, see PDF Inline (GIF) Technical note 1 HDR 2007/2008 [5,680 KB]and also the interactive HDI calculator and the Excel tool Excel Inline (GIF) Calculating the indices [61 KB] - interactive tools that help understand the calculation of the HDI.
