Very little is currently known about the demographic impact of most development projects and the ways in which this impact can be assessed. This book, based on studies in Third World countries, focuses on conceptual, methodological and policy issues in its evaluation of the demographic impact of development projects. The author examines whether demographic effects can be assessed and why development planners should be interested in the results. A.S. Oberai examines to what extent economic and social ranges generated by specific development interventions have influenced demographic behavior in a particular context. He suggests how desired effects can be enhanced and undesirable effects minimized by policy-makers and planners in developing countries in order to deal with problems of population growth and its distribution. The major shortcomings of existing methodologies are identified and future directions which research might take are outlined. The study is based on a synthesis of country studies reviewing the demographic impact of development projects carried out in Bangladesh, Indonesia, the Philippines and Thailand. It also includes analyses of the demographic impact of development interventions in several other countries such as Brazil, Colombia, Costa Rica, India, and Nigeria.
