The Human Development Index (HDI) is a broad measure of a nation’s social and economic development in regard to quality of life. It was first developed in 1990 by Pakistani economist Mahbub ul Haq and Indian economist Amartya Sen. The formula has since been revised by the United Nations Development Programme. The formula used in this index is the 2010 UNDP formula. The Human Development Index ranks nations based on life expectancy, education, and incomes. The scores are normalised to range between one and zero, with one being the most developed and zero being the least developed, although a country can theoretically score above or below these values.
