The Human Development Index (HDI) is the normalized measure of life expectancy, literacy, education, standard of living, and GDP per capita for countries worldwide. It is a standard means of measuring well-being, especially child welfare. It is used to determine and indicate whether a country is a developed, developing, or underdeveloped country. It is also used to measure the impact of economic policies on quality of life.[1]

The index was developed in 1990 by Indian Nobel prize winner Amartya Sen, Pakistani economist Mahbub ul Haq and Sir Richard Jolly, with help from Gustav Ranis of Yale University and Lord Meghnad Desai of the London School of Economics and has been used since then by the United Nations Development Programme in its annual Human Development Report. Described by Sen as a "vulgar measure", because of its limitations, it nonetheless focuses attention on wider aspects of development than the per capita income measure it supplanted, and is a pathway for researchers into the wide variety of more detailed measures contained in the Human Development Reports.
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 and education, as measured by the adult literacy rate (with two-thirds weighting) and the combined primary, secondary, and tertiary gross enrollment ratio (with one-third weighting).
- A decent standard of living, as measured by the natural logarithm of 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,[2] 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.
Methodology
In general to transform a raw variable, say , into a unit-free index between 0 and 1 (which allows different indices to be added together), the following formula is used:
- -index =
where and are the lowest and highest values the variable can attain, respectively.
The Human Development Index (HDI) then represents the average of the following three general indices:
- Life Expectancy Index =
- Education Index =
- Adult Literacy Index (ALI) =
- Gross Enrollment Index (EI) =
- GDP Index =
LE: Life expectancy at birth
ALR: Adult literacy rate (ages 15 and older)
CGER: Combined gross enrollment ratio for primary, secondary and tertiary schools
GDPpc: GDP per capita at PPP in USD
UNDP has created a technical note on the definition of the HDI (see links below).
Examples
Index | Measure | Minimum value | Maximum value | Formula |
---|---|---|---|---|
Longevity | Life expectancy at birth (LE) | 25 yrs | 85 yrs | |
Education | Literacy rate (LR) | 0% | 100% | |
Combined gross enrollment ratio (CGER) | 0% | 100% | ||
GDP | GDP per capita (PPP) | 100 USD |

2007 report
The report for 2007 was launched in Brasilia, Brazil, on November 27, 2007. Its focus was on "Fighting climate change: Human solidarity in a divided world." [1] Most of the data used for the report are derived largely from 2005 or earlier, thus indicating an HDI for 2005. Not all UN member states choose to or are able to provide the necessary statistics.
The report showed a small increase in world HDI in comparison with last year's report. This rise was fueled by a general improvement in the developing world, especially of the least developed countries group. This marked improvement at the bottom was offset with a decrease in HDI of high income countries.
A HDI below 0.5 is considered to represent "low development". All 22 countries in that category are located in Africa. The highest-scoring Sub-Saharan countries, Gabon and South Africa, are ranked 119th and 121st, respectively. Nine countries departed from this category this year and joined the "medium development" group.
A HDI of 0.8 or more is considered to represent "high development". This includes all developed countries, such as those in North America, Western Europe, Oceania, and Eastern Asia, as well as some developing countries in Eastern Europe, Central and South America, Southeast Asia, the Caribbean, and the oil-rich Arabian Peninsula. Seven countries were promoted to this category this year, leaving the "medium development" group: Albania, Belarus, Brazil, Libya, Republic of Macedonia, Russia and Saudi Arabia.
On the following table, green arrows () represent an increase in ranking over the previous study, while red arrows (
) represent a decrease in ranking. They are followed by the number of spaces they moved. Blue dashes (
) represent a nation that did not move in the rankings since the previous study.

Countries not included
The following United Nations member states are not ranked in the 2007 Human Development Index, for being unable or unwilling to provide the necessary data at the time of publication. The exception in the list is the Republic of China, which is not a member of the United Nations.
