This book offers a systematic historical analysis of the relationships between migration and the development of cities, including their physical, economic, and cultural evolution. The volume results from a comparative project that examines the interface between migration and the development of cities throughout different periods including current conditions. Nine strategic sites are examined: Three cities in Europe, three in Latin America and three in North America. The editors contribute to the analysis by summarizing lessons from the cases discussed and by providing a glimpse at the relevance of the study of migration and cities historically. Urbanization and Migration in Three Continents will be a key resource for academics, researchers, and students of sociology, migration studies, race and ethnic studies, history, anthropology, urban studies, and economics. This book was originally published as a special issue of Ethnic and Racial Studies.
