Adopting an empirical interdisciplinary approach, Ettore Recchi and Mirna Safi draw together incisive contributions from a wide range of experts in the fields of sociology, geography, political science and demography. Chapters explore circular migration, public opinion on immigration, visa and border infrastructure and debates on whether international migration is truly global. They examine the critical research gap between mobility and migration, and address paramount questions using state-of-the-art theories and evidence. Providing concise overviews of issues at the top of the current research agenda in the field, this timely Handbook will be an essential reference for students and academics of migration studies, sociology, social policy, political science, human geography, demography, and international relations. It will also be of significant interest to researchers and policy professionals operating in these fields.
