Human Development Index (HDI) is a statistical tool used to measure a country's
overall achievement in its social and economic dimensions. Detailed information
on this is available here. http://www.arab-hdr.org/publications/contents/2002/ch1-e.pdf
Social and economic dimensions of a country are based on the health of people,
their level of education and their standard of living. Calculation of the index
combines four major indicators: life expectancy for health, expected years of
schooling, mean of years of schooling for education and Gross National Income
per capita for standard of living. HDI is one of the best tools to keep track
of the level of development of a country, as it combines all major social,
secular and economic indicators, responsible for economic development. Every
year UNDP ranks countries based on the HDI report included in their annual
report. It is found that some countries with lots of income do not always spend
that money in ways that create high life expectancies or education levels.
Mathematical expression for estimating the index is as under.
