The Human Development Index (HDI) is a quantitative measure of development allowing for comparisons across countries and over time. Three main dimensions comprise the index: life expectancy at birth, years of schooling for adults aged 25 years and more and expected years of schooling for children of school entering age, and gross national income per capita.
