In the broadest sense, The Well-Being of the Elderly in Asia is a study of social change and of anticipating future social change. It examines the effects on the current and future elderly of the rapid demographic transition that has occurred over much of Asia, accompanied in many countries by equally dramatic social and economic transformations. Policymakers in Asia have been aware of these trends and their potentially deleterious consequences for a decade or more, and have sought to fashion appropriate policies and programs that anticipate and mitigate their effects. Accordingly, any study of the sociodemographic trends and their impact must be examined in the light of policies put in place and under development.
