Grant: HOME/2013/EIFX/CA/002 / 30-CE-0615920/00-38 (DI130895) A previous version of this paper was presented and discussed at the OECD Working Party on Migration in June 2015. The paper investigates the main likely drivers of migration towards the EU. It encompasses a literature review on the determinants of potential and actual migration, followed by an illustrative empirical investigation of worldwide migration intentions – focused on intentions to move permanently in a restricted time span, based on the Gallup surveys on the opinions and aspirations of people around the globe. The paper then continues with a descriptive analysis of migration intentions using both aggregated figures and figures disaggregated by region or country of destination and region or country of origin. It then investigates if individuals intending to move to European countries differ from those intending to move elsewhere using basic individual characteristics such as sex, age, education, and marital and employment status. When feasible, it compares the findings with the profile of recent migrants residing in OECD countries derived from the Database on Immigrants in OECD and non-OECD Countries.
