Define HDI

Short answer

The Human Development Index (HDI), published by UNDP, is a composite measure of average achievement in health (life expectancy), education (mean and expected years of schooling) and standard of living (GNI per capita, PPP). It ranges from 0 to 1, with countries grouped as low, medium, high and very high development.

Define HDI (Human Development Index).

The Human Development Index (HDI) is a summary measure published by the United Nations Development Programme (UNDP) that assesses a country's average achievement in three basic dimensions of human development:

  1. Health: a long and healthy life, measured by life expectancy at birth.
  2. Education: knowledge, measured by mean years of schooling (adults) and expected years of schooling (children).
  3. Standard of living: measured by gross national income (GNI) per capita in purchasing power parity (PPP) dollars.

HDI is the geometric mean of the three normalised dimension indices, with a value between 0 (lowest) and 1 (highest). Countries are grouped as low, medium, high and very high human development. Nepal is in the medium group, with an HDI of about 0.6 (the exact value changes with each report). It was introduced in 1990 by Mahbub ul Haq and Amartya Sen.
