Multiculturalism and migration are related. In Europe, multiculturalism normally denotes the fact that European societies now house significant groups of immigrant origin. Nevertheless, multiculturalism and migration are about different things. Migration is about movement of people across borders. It raises political questions about state sovereignty, territorial rights, and freedom of movement. Multiculturalism is rather about political measures for handling and accommodating diversity within a given society. It raises political questions about equality, discrimination, and integration. Therefore, while there are connections, multiculturalism and migration should be theorized differently and discussed on the basis of different principles and considerations. This distinction between multiculturalism and migration has nevertheless been blurred in recent policy developments. The blurring happens in two opposite directions: The multiculturalism backlash, i.e. the criticism of and hostility towards multiculturalism policies, has been extended to migration: Because of hostility to diversity within societies and multiculturalism policies supposed to accommodate this diversity, migration itself has become an object of criticism and hostility. Migration policy has been subordinated to concerns relating to multicultural diversity. Conversely, an analogous migration-backlash, i.e. the widespread political unease about migration, has led to increased demands being placed on minorities already present: They are being subjected to harsher integration requirements, lower social benefits and more severe conditions for family-unification and naturalization. Multiculturalism policies have been subordinated to concerns relating to migration. The chapter identifies the empirical developments leading to these forms of subordination, provides a theoretical account of them, and argues that both forms of subordination are normatively problematic.
