This chapter provides an overview of how international migration movements have evolved in OECD countries. After a quick glance at 2015 migration flow trends, it presents an analysis of the trends in permanent migration between 2007 and 2014, by country and by main category of migration – migration for work, family or humanitarian purposes, and migration within free movement areas. The next section covers temporary labour migration flows, paying particular attention to seasonal workers, posted workers and Working Holiday Makers. The chapter then takes up the dramatic rise in the number of asylum seekers in OECD countries and furnishes a brief overview of international student mobility, gender composition of flows by country of destination, size of foreign-born populations, and the acquisition of nationality in OECD countries. The chapter concludes with a policy section relating the main changes in countries’ migration management frameworks, in particular in the European Union.
