Education Index

The Education Index is a component of the Human Development Index (HDI) published every year by the United Nations Development Programme. Alongside the economical indicators (GDP) and Life Expectancy Index, it helps measure the educational attainment. GNI (PPP) per capita and life expectancy are also used with the education index to get the HDI of each country.

Since 2010, the education index has been measured by combining average adult years of schooling with expected years of schooling for students under the age of 25, each receiving 50% weighting. Before 2010, the education index was measured by the adult literacy rate (with two-thirds weighting) and the combined primary, secondary, and tertiary gross enrollment ratio (with one-third weighting).

Education is a major component of well-being and is used in the measure of economic development and quality of life, which is a key factor determining whether a country is a developed, developing, or underdeveloped country.
