How does un of human development report compare countries?

The United Nations Development Programme (UNDP) Human Development Report compares countries using the Human Development Index (HDI), which evaluates three key dimensions: health (life expectancy at birth), education (mean years of schooling and expected years of schooling), and standard of living (Gross National Income per capita). Countries are ranked based on their HDI scores, providing a composite measure that reflects overall human well-being rather than just economic performance. This approach highlights disparities in development and emphasizes the importance of education and health in improving quality of life.
