What does the Human Development Index take into account for its measurements?

The Human Development Index (HDI) is a composite statistic that measures a country's overall development based on three key dimensions: health, education, and income. Health is assessed through life expectancy at birth, which reflects the overall well-being of a population. Education is considered using indicators such as mean years of schooling and expected years of schooling, providing insight into the education levels attained and anticipated in a population. Finally, income is evaluated through gross national income per capita, adjusted for purchasing power parity, to represent the economic prosperity available to individuals within a country.

Focusing on these three areas provides a more comprehensive understanding of human development than economic output alone, as it also incorporates social factors that contribute to quality of life. This multidimensional approach emphasizes that development should not only be measured by economic wealth but also by how that wealth is translated into human capabilities and opportunities.
