Population and Society: An Introduction to Demography is an ideal text for undergraduate, as well as graduate, students taking their first course in demography. It is sociologically oriented, although economics, political science, geography, history, and the other social sciences are also used to inform the materials. Although the emphasis is on demography, the book recognizes that, at the individual level, population change is related to private decisions, especially in relation to fertility, but also to mortality and migration. The text thus considers in some detail the role of individuals in population decision making. At the level of countries, and even the world, changes in population size have an important effect on the environmental and related challenges facing all of the world's inhabitants. Therefore, attention is paid to the broad implications of population growth and change.
