Book excerpt: The SAGE Handbook of International Migration provides an authoritative and informed analysis of key issues in international migration, including its crucial significance far beyond the more traditional questions of immigrant settlement and incorporation in particular countries. Bringing together chapters contributed by an international cast of leading voices in the field, the Handbook is arranged around four key thematic parts: Part 1: Disciplinary Perspectives on Migration Part 2: Historical and Contemporary Flows of Migrants Part 3: Theory, Policy and the Factors Affecting Incorporation Part 4: National and Global Policy Challenges in Migration The last three decades have seen the rapid increase and diversification in the types of international migration, and this Handbook has been created to meet the need among academics and researchers across the social sciences, policy makers and commentators for a definitive publication which provides a range of perspectives and insights into key themes and debates in the field.
