Filling a critical gap in the present market, this comprehensive, multidisciplinary collection of readings is specifically designed as a sourcebook on population. It includes articles from all major theoretical perspectives and from all levels of aggregation from micro-decision making processes to macro-historical processes. Mainstream issues include: the economics of fertility, social causes of mortality, illegal immigration and refugee migration, Third World urbanization, Malthusian, Marxian and demographic transition theory, the census undercount, and population policy in more and less developed countries and in socialist and capitalist countries. New or hitherto neglected issues include: the extermination of native populations by colonial powers, husband-wife differences in determining family size, and the recently reported increase in infant mortality in the Soviet Union.
