Who developed Human Development Index?

The Human Development Index (HDI) was developed by the United Nations Development Programme (UNDP) in 1990. It was introduced by the Pakistani economist Mahbub ul Haq and the Indian economist Amartya Sen to provide a broader measure of development beyond just economic indicators like GDP. The HDI incorporates factors such as life expectancy, education, and per capita income to assess the overall well-being and quality of life in different countries.
