Human Development Index

The Human Development Index (HDI) is a comparative measure of life expectancy, literacy, education, and standards of living for countries worldwide. It is a standard means of measuring well-being, especially child welfare. It is used to distinguish whether the country is a developed, developing, or under developed country, and also to measure the impact of economic policies on quality of life.^{[1] The index was developed in 1990 by Pakistani economist Mahbub ul Haq, and has been used since 1993 by the United Nations Development Programme in its annual Human Development Report.}

The HDI measures the average achievements in a country in three basic dimensions of human development:

A long and healthy life, as measured by life expectancy at birth.
Knowledge, as measured by the adult literacy rate (with two-thirds weight) and the combined primary, secondary, and tertiary gross enrolment ratio (with one-third weight).
A decent standard of living, as measured by gross domestic product (GDP) per capita at purchasing power parity (PPP) in USD.

Each year, UN member states are listed and ranked according to these measures. Those high on the list often advertise it (e.g., Jean Chrétien, Former Prime Minister of Canada [1]), as a means of attracting talented immigrants (economically, individual capital) or discouraging emigration.

An alternative measure, focusing on the amount of poverty in a country, is the Human Poverty Index.

………………………………

An HDI below 0.5 is considered to represent low development and 29 of the 31 countries in that category are located in Africa, with the exceptions of Haiti and Yemen. The bottom ten countries are all in Africa. The highest-scoring Sub-Saharan countries, Equatorial Guinea and South Africa, are ranked 120th and 121st, respectively (with a shared HDI of 0.653).

An HDI 0.8 or more is considered to represent high development. This includes all developed countries and some developing countries in mainly Eastern Europe, Latin America, Southeast Asia and oil-rich Arabian Peninsula.
