Book excerpt: Now with more balanced coverage of Western and non-Western regions, this leading text has been revised and updated with the latest theories, policy information, and interdisciplinary research. The book explores the causes, dynamics, and consequences of international population movements, as well as the experiences of migrants themselves. Chapters examine migration trends and patterns in all major world regions, how migration transforms both destination and origin societies, and the effects of migration and increasing ethnic diversity on national identity and politics. Useful pedagogical features include boxed case studies; extensive tables, graphs, and maps; end-of-chapter Guides to Further Reading; and a companion website with additional case studies, interactive flashcards, and other resources for students and instructors.--
