The document discusses development indicators that can be used to measure and compare the social and economic development of countries. It describes several common indicators such as GNP per capita, literacy rate, infant mortality rate, percentage of people employed in farming, and life expectancy. It also notes some criticisms of development indicators, such as that they often hide differences within countries and some statistics can be misleading depending on their context. The document then introduces the Human Development Index as a composite measure of development that takes into account health, education, and standard of living factors.
