The document discusses the Human Development Index (HDI), which was created by Pakistani economist Mahbub ul Haq in 1990. The HDI is a composite statistic that measures a country's development according to life expectancy, education, and income indicators. It is calculated using a formula that averages a nation's scores on health, education, and income. Health is measured by life expectancy, education by adult literacy and expected years of schooling, and income by gross national income per capita. Countries are ranked high to low on human development and the top and bottom ten countries are listed. The document also notes Pakistan's ranking of 147th on the HDI.
