It also monitors recent policy changes in migration governance and integration in OECD countries. This edition includes two special chapters, one providing an in-depth analysis of the fiscal impact of migration in OECD countries since the mid 2000s and another on the causes and consequences of the residential segregation of immigrants. The Outlook also includes country notes and a detailed statistical annex.
