This annual publication analyzes recent developments in migration movements and policies in OECD countries. It looks at the contribution of immigration to changes in the working-age population in the past decade, and the role of migration inflows at projected levels in driving growth of the working-age population in the next decade. It presents information on international students, including a first attempt to calculate the rates at which these students remain in their host countries after the completion of their studies. This publication also explores the main changes introduced in migration policies, including new laws governing immigrant entry, stay and access to the labor market. The selective recruitment of immigrants according to labor market needs and points-based systems is described, as well as measures to facilitate the integration of immigrants. International cooperation to improve border control and to combat irregular migration is analyzed in detail.
