Trager and her coauthors focus on migration not as a single event but as a dynamic process that responds to and is shaped by broader economic, cultural, and social forces. Individual essays consider issues of international and internal migration; of transnational and multilocal networks through which remittances and other flows take place; and of migrants as active agents. They offer original studies on Mexico, Puerto Rico, West Africa, Kazakstan, and Mozambique. This new volume will be a valuable resource in development anthropology, migration studies, and international planning and policy.
