In a world of rapidly growing superdiversity, migration itself is also changing. In addition to classic migration - from one country oforigin to one country of destination - new and more complex migration patterns are developing. Transmigration - or multiplemigration - implies that people now arrive after stays in several countries en route, and may later move on again. In the big cities,but also in smaller towns, we are seeing increasingly large groups of these transmigrants, often in vulnerable social situations.
