The Human Development Index (HDI) is a composite statistic used to measure a country's average achievements in three basic aspects of human development: health, education, and standard of living. It was developed by the United Nations Development Programme (UNDP) in 1990 as part of the Human Development Report.
The HDI provides a summary measure of human development, allowing for comparisons between countries and tracking progress over time. It emphasizes that economic growth alone is not sufficient for improving well-being and highlights the importance of health and education in development.
