Also new to this edition is a companion website including:

• Case studies
• Web links
• Updates
• A web-only chapter

Reviews of the Fourth Edition:
 
" [A]n impressive achievement. The empirical detail is striking, the historical overview comprehensive and the theoretical overview clear and easy to follow even without prior sophisticated knowledge of the theories covered. As an overview to the field of migration studies, this well-written [excellent fourth edition] more than serves its purpose..." - Helena Ekelund, Journal of Contemporary European Research
 
Reviews of previous editions:

'Widely and deservedly praised as a major achievement... 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

'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
