What is HDI?

HDI means Human development index, an important measure designed by the UN (United Nations) to evaluate the quality of life and economic development of a population.

Annually is the Human development report (HDR, see related article) by the United Nations Development Programme (UNDP) based on three pillars (health, education and income) which are measured as follows:

  • A long and healthy life (Health): life expectancy at birth
  • Access to knowledge (Education): average years of study (adults) and expected years of schooling (children)
  • A decent standard of living (Income): measured by Gross national income (GNI) based on purchasing power standards (PPS) per inhabitant

The HDI varies between 0 (no human development) and 1 (total human development), revealing that the greater the proximity of 1, the more developed the country. The world average of 187 countries evaluated in 2011 was 0.682. Below is a list of the first 10 countries in the HDI Ranking Global 2011:
