This article contains information based on the pre-2011 Human Development Reports. The HDI and its education component have changed in 2011.
The United Nations publishes a Human Development Index every year, which consists of the Education index, GDP Index and Life Expectancy Index. These three components measure the educational attainment, GDP per capita and life expectancy respectively.
The Education Index is measured by the adult literacy rate (with two-thirds weighting) and the combined primary, secondary, and tertiary gross enrollment ratio (with one-third weighting). The adult literacy rate gives an indication of the ability to reading and writing, while the GER gives an indication of the level of education from nursery (UK & others)/kindergarten (USA & others) to post-graduate education.
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.
Change in value from the last report is given as follows:
- = increase.
- = steady.
- = decrease.
The latest index was released in the Human Development Report in October 2009. This statistical update covers the period up to 2007: 1 is the highest possible theoretical score, indicating perfect education attainment.
All countries considered to be developed countries possess a minimum score of 0.8 or above, although the great majority have a score of 0.9 or above. For ranking based on the Human Development Index, see List of countries by Human Development Index.
