International migration is a momentous and complex phenomenon, affecting millions of people in sending and receiving countries alike. The mediatized movement of people across borders has been a source of anxiety for many societies, as is witnessed by the world-wide rise of populist, anti-immigration politics. In such a juncture, there is a desperate need for reliable academic knowledge and insights. Migration written by two internationally acclaimed scholars provides a timely and carefully written overview of the state-of-the-art in this field. A must read book for anyone interesting in understanding our globalizing world.'Prof. Dr. Jan Rath, Professor of Sociology, University of Amsterdam, The Netherlands'Samer's and Collyer's text is a masterly tour de force, reviewing theories of migration, employment, citizenship and belonging. Wonderfully comprehensive yet engagingly accessible, it will become key reading for all students of migration across the social sciences.'Professor Linda McDowell, School of Geography and the Environment, University of Oxford, UK'This is a timely edition and a tour de force. Collyer and Samers answer the key questions about the dynamics of international migration, the incorporation of migrants and their descendants in host societies, markets and polities as well as the policies that are likely to affect these phenomena. They do so by a stimulating analysis of cutting edge research across social science disciplines. The book convincingly shows the contribution of geography and spatial concepts to the understanding of international mobility, its causes and consequences.' Virginie Guiraudon, Research Director at the Sciences Po Center for European Studies, France'International Migration is both a transnational movement that span state borders and a local phenomenon that imbues the everyday experience of people. Collyer and Samers propose a comprehensive and much-needed outlook of the different migration theories. They masterfully elicit the complex mechanics of international migrations and compellingly use the tools of geography to hold together the different scales and facets of migration processes. Migration is a must-read for students and scholars of migration.
