Today, approximately 3.4 percent of the world’s population are international migrants – people living outside their country of birth. In the future, the number of people who move from one country to another may increase due to population growth in developing countries, increased mobility, political unrest in some world regions, and climate change. The question is how much may international migration flows increase and where will migrants go? The Horizon 2020 project Future migration scenarios for Europe (FUME) focuses on understanding the patterns, motivations, and modalities of migration at multiple geographical scales, from international through regional to the local, and on developing possible future scenarios of migration to Europe. These scenarios shall improve our understanding of the complexity and diversity of migration – and support migration, integration, labour market and cohesion policies at different governance levels. This policy brief answers key FUME research questions, summarizes important project findings, and presents policy recommendations. It is based on fieldwork carried out in selected countries of origin including in-depth individual and group interviews of migrants, a review of migration literature, an expert survey of migration researchers, and a Delphi survey of migration experts.
