HDI Stand for Human Development Index.
Main criteria of measuring HDI:
1. HDI published by UNDP compares countries based on the educational levels of the people, their health status and per capita income.
2. HDI determines the rank of a country by its overall achievement in three areas, i.e., life expectancy, educational level and per capita income.
3. Many improvements have been suggested in calculating HDI and many new components have been added to Human Development Report.
4. Pre-fixing Human to Development, it has made it clear that what is important in development is what is happening to citizens of a country, i.e., the health and well being of the people is most important.
