Human Development Index
From Open Encyclopedia
The UN Human Development Index (HDI) is a comparative measure of poverty, literacy, education, life expectancy, childbirth, and other factors for countries worldwide. It is a standard means of measuring well-being, especially child welfare. The index was developed in 1990 by the Pakistani economist Mahbub ul Haq, and has been used since 1993 by the United Nations Development Programme in its annual 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 enrollment 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, as a means of attracting talented immigrants (economically, individual capital) or discouraging emigration.

Method used to calculate the Human Development Index
The Human Development Index (HDI) represents the average of the following three indices:
- Life Expectancy Index = <math>\frac{LE - 25} {85 - 25}</math>
- Education Index = <math>\frac{2} {3} \times ALI + \frac{1} {3} \times GEI</math>
- Adult Literacy Index (ALI) = <math>\frac{ALR - 0} {100 - 0}</math>
- Gross Enrollment Index (GEI) = <math>\frac{CGER - 0} {100 - 0}</math>
- GDP Index = <math>\frac{\log(GDPpc) - \log(100)} {\log(40000) - \log(100)}</math>
LE: Life expectancy
ALR: Adult literacy rate
CGER: Combined gross enrollment ratio
GDPpc: GDP per capita at PPP in USD
2005 report
The report for 2005 shows that, in general, the HDI for countries around the world is improving, with two major exceptions: Sub-Saharan Africa and Post-Soviet states, both of which showed steady decline. HIV/AIDS is seen as the principal cause of the decline in the first group, while worsening education, economies, and mortality rates caused declines in the HDIs amongst the latter group.
Most of the data used for the 2005 report, indicating country HDIs for 2003, are derived largely from 2003 or earlier. The top ten countries are in Europe, North America, and Oceania. Conversely, all but two of the 32 countries exhibiting low human development are in Africa. However, not all UN member states choose to or are able to provide the necessary statistics. Notable absences from the list include Afghanistan, Iraq, Liberia, North Korea, Serbia and Montenegro, and Somalia. While these countries are either unwilling or unable to provide data, they are generally considered countries of medium to low human development.
Note: Number in parentheses indicates change in rank since last report.

* The Republic of China (Taiwan) has calculated its HDI to be 0.910 for 2003 based on the following data: life expectancy of 76.1 years, adult literacy rate of 97.0%, combined enrollment rate of 97%, and GDP per capita (PPP) of US$23,911. If included among UN HDI figures, Taiwan would rank 25th: behind Greece and in front of Singapore. [1]
