World Migration Report: Costs and Benefits of International Migration, Volume 3, 2005

World Migration 2005 analyses the effects of globalisation, trade liberalisation, economic integration and the widening gap between rich and poor nations on migration flows. It looks at the impact of the world's 185 million migrants and their potential contribution to socioeconomic development and cultural enrichment both at home and abroad. And it identifies the multidimensional migration management policies needed by governments to create the optimal return to both migrants and society, while minimizing the abuses associated with irregular migration.
