United Nations Development Program (UNDP): Human Development Report
United Nations Development Program publishes a widely circulated annual report, namely the Human Development Report, which contains indicator tables for 191 UN member countries along with Hong Kong, SAR (China) and Occupied Palestinian Territories. These countries and areas are classified in four ways: by human development level, by income, in major world aggregates and by region. All countries included in the HDI are classified into three clusters by achievement in human development: high human development (with an HDI of 0.800 or above), medium human development (0.500–0.799) and low human development (less than 0.500). It is an annual publication that is normally launched in June or July and also available online at www.undp.org.
The HDI (human development index) is a composite index that measures a country's average achievements in three basic areas of human development: longevity, knowledge, and a decent standard of living. Longevity is measured by life expectancy at birth; knowledge is measured by a combination of the adult literacy rate and the combined primary, secondary, and tertiary gross enrolment ratio; and standard of living by GDP per capita (PPP US$).
