HDI

Human Development Index (HDI) is a measure used to assess a country's overall development based on three key dimensions: health, education, and standard of living. It combines life expectancy, educational attainment (like years of schooling), and income per capita into a single index. Countries are scored on a scale from 0 to 1, with higher values indicating better development. HDI helps to compare the well-being and quality of life among nations, highlighting not just economic factors, but also health and education, providing a broader view of human progress.
