This report on the German results of the Integration of the Second Generation in Europe (TIES) survey looks at the integration process for second-generation inhabitants of Turkish and Yugoslavian backgrounds living in Berlin and Frankfurt. A common expectation in migration research is that second-generation immigrants in Europe should already be gaining equality with the majority population, a process that should lead to complete assimilation for subsequent generations. At the same time, migration shapes host societies as much as these societies shape migration. Examining the TIES results through the lens of this two-way process, Inken Sürig and Maren Wilmes discuss diverse topics such as educational outcomes, segregation and housing, ethnic and cultural orientations, and social relations.
