The Human Development Index (HDI) is a widely used composite measure developed by the United Nations to provide a more holistic assessment of a country's development than economic indicators alone. Which set of indicators is combined to calculate a nation's HDI score?
Life expectancy at birth, mean and expected years of schooling, and Gross National Income (GNI) per capita (adjusted for PPP)
Infant mortality rate, adult literacy rate, and Gross Domestic Product (GDP) per capita
Life expectancy at birth, percentage of the population with access to safe water, and Gross National Income (GNI) per capita
Birth rate, primary school enrollment rate, and net overseas investment income
