The Journey Ahead: Supporting Successful Migration in Europe and Central Asia provides an in-depth analysis of international migration in Europe and Central Asia (ECA) and the implications for policy making. By identifying challenges and opportunities associated with migration in the region, it aims to inform a more nuanced, evidence-based debate on the costs and benefits of cross-border mobility. Using data-driven insights and new analysis, the report shows that migration has been an engine of prosperity and has helped address some of ECA's demographic and socioeconomic disparities. Yet, migration's full economic potential remains untapped. The report identifies multiple barriers keeping migration from achieving its full potential. Crucially, it argues that policies in both origin and destination countries can help maximize the development impacts of migration and effectively manage the economic, social, and political costs. Drawing from a wide range of literature, country experiences, and novel analysis, The Journey Ahead presents actionable policy options to enhance the benefits of migration for destination and origin countries and migrants themselves. Some measures can be taken unilaterally by countries, whereas others require close bilateral or regional coordination. The recommendations are tailored to different types of migration--forced displacement as well as high-skilled and low-skilled economic migration--and from the perspectives of both sending and receiving countries. This report serves as a comprehensive resource for governments, development partners, and other stakeholders throughout Europe and Central Asia, where the richness and diversity of migration experiences provide valuable insights for policy makers in other regions of the world.
