This volume provides a social science introduction to migration processes from a global perspective and reflects the current state of discussion. It places societal debates around migration at its center and incorporates migrant perspectives. While migration research in Germany is often conducted as integration research, this book also examines migration phenomena from the viewpoint of emigration and transit countries. Additional topics include the social construction of migration through statistics, migration theories from various schools of thought, and migration from a gender-analytical perspective. Questions about whether migration can be managed and the relevance of distinguishing between flight and migration are further issues that shape both scientific and political discussions.
