International migration is a central aspect of globalization in the contemporary world and is recasting states and societies in a range of distinctive and important ways. The updated and extensively revised 3rd edition of this leading text provides up-to-date coverage of the nature, extent and dimensions of international population movements and of their consequences in an increasingly multicultural world. An entirely new chapter addresses the problems of regulating migration at both state and regional levels, including the security implications in the context of September 11 and the 'war on terrorism'.Reviews of 2nd edition:'[T]he first edition... widely and deservedly praised as a major achievement. The second edition is a substantially improved version... Castles and Miller have their own distinctive model of the migratory process but manage at the same time to cover almost every major theme of current migration studies.' - Rainer Bauböck, 'Ethnic and Racial Studies''...includes an historical account of the major migratory trends before the second world war, supplemented by up-to-date, comprehensive analysis of 'new migrations'. The outstanding strength of this volume is that its critique of causal explanations of migration is married to an exploration of the impact of immigration on 'host' societies.' - Susan Carruthers, 'Times Higher Education Supplement'
