This data book presents satistics on countries with populations of more than one million. The statistics relate to economic development and the changes it is bringing about in the world. These statistics are measures of social and economic conditions in developing and industrial countries. Five indicators of economic development are presented, including color-coded maps and charts for clarification. Many charts present changes between 1965 and 1986, the year of the most current data. Section 1, "Life Expectancy," addresses the proportion of deaths by age, the percentage of infants surviving the first year of life, and life expectancy at birth. Section 2, "Primary School Enrollment Rate," covers primary school enrollment rates (1965 and 1985), male/female enrollment rates in developing countries (1965 and 1985), and persistence in primary school (1980-1985). Section 3, "Population Growth Rate," charts growth in developing and industrial countries (1950-1986); population size, average annual growth, and average annual increase in developing countries (1965-1986); and population projections for 1986 and 2000. Section 4, "GNP per Capita," deals with gross national product, population, and GNP per capita; their growth between 1965-1980 and 1980-1986; and the distribution of world population by GNP per capita (1986).
