The Subnational Human Development Index
The Human Development Index is a composite index of life expectancy, education, and per capita income indicators, which are used to classify countries into 4 tiers of human development. A country scores a higher Human Development Index when the lifespan is higher, the education level is higher, and the gross national income per capita is higher.
Human Development Index is usually presented on a national level. However, the Human Development Index can vary a lot within a country. For example, the state in the U.S. with the highest Human Development Index is Massachusetts at 0.959, while the lowest is Mississippi, at 0.867.
