In BICC Policy Brief 5\2019 "Key to the successful integration of displaced persons: Language competence, housing, work, social participation" (in German), author Simone Christ understands integration as participation for all people that is as equitable as possible. Integration is a process of encounter and exchange, not a unilateral adaptation effort by migrants. Socio-political challenges—such as the protracted difficulties on the housing market or in the school system—can make equal participation more difficult. However, solutions must be found here that involve not only displaced people but all strata of the population in order to avoid conflicts and competition.
