Examines patterns of demographic behavior and looks at their potential impact on human societies in the 21st century. Looks at recent, current, and future population growth, the possibilities of increased mortality in some parts of the world, and international migration. The US, Germany, and Japan are studied as models for typical "receiving" countries in immigration, and Mexico, Turkey, and the Philippines as typical "sending" countries. The authors are adjunct professor of demography and chair of the Department of International Health at Tulane University. Annotation c. Book News, Inc., Portland, OR (booknews.com)
