Report of the United Nations Development Programme 2004 (HDI 2002). Launched by the United Nations in 1990, the Human Development Index measures a country's achievements in three aspects of human development: longevity, knowledge, and a decent standard of living. It was created to re-emphasize that people and their lives should be the ultimate criteria for assessing the development of a country, not economic growth. Current values range from 0.956 ( Norway, 1/177 countries) to 0.273 ( Sierra Leone, 177/177 countries). Countries fall into one of three groups: countries1-55=high development; 56-141=medium development; 142-177=low development.

Total health expenditure per capita is the per capita amount of the sum of Public Health Expenditure (PHE) and Private Expenditure on Health (PvtHE). The international dollar is a common currency unit that takes into account differences in the relative purchasing power of various currencies. Figures expressed in international dollars are calculated using purchasing power parities (PPP), which are rates of currency conversion constructed to account for differences in price level between countries.
