Internal migration and urbanization are key dimensions of the process of socioeconomic development. The unprecedented movement of peoples within the borders of their own countries is one of the greatest transformations witnessed in the 20th century. Policy analysts, especially those from developing countries where internal migration can be felt at first hand, view migration as one of the most important factors affecting the course of development. It is within this context that UNFPA convened the Symposium on Internal Migration and Urbanization in Developing Countries in January 1996 in preparation for the United Nations World Conference on Human Settlements in Istanbul in June 1996. The final results of the symposium are found in this book. This volume provides a better understanding, at global level, of internal migration issues of concern to policy analysts.
