What measures does the HDI utilize to evaluate developmental progress?

The Human Development Index (HDI) evaluates developmental progress primarily through three key dimensions: health, education, and income metrics.

Health is measured through life expectancy at birth, which reflects the overall health of a population and its access to healthcare services. Education is assessed using two components: the mean years of schooling for adults and the expected years of schooling for children, indicating the level of educational attainment and the potential for future education. Income is measured by gross national income (GNI) per capita, adjusted for purchasing power parity, which provides insight into the economic resources available to individuals and affects their quality of life.

This combination of health, education, and income provides a more comprehensive picture of human development than just economic measures, highlighting the importance of quality of life and well-being alongside material wealth. The HDI thus aims to present a broader perspective on development beyond traditional economic indicators alone.
