The Link between Social and Structural Integration: Co- and Interethnic Friendship Selection and Social Influence within Adolescent Social Networks

Assimilation theories argue that social ties with majority-group members enhance the structural integration of ethnic minority members, whereas under certain conditions, coethnic social ties can also benefit minority members' socioeconomic outcomes. We examine these propositions through a social network perspective, focusing on friendship networks and educational expectations in adolescence, during which peer socialization is crucial. Longitudinal data from 1,992 adolescents in 91 classrooms allow us to investigate co- and interethnic social selection and social influence processes as well as their aggregated outcomes. In terms of friendship selection, we find that Turkishorigin minority adolescents in Germany have distinct preferences for friends with high educational expectations, among both co- and interethnic peers. In contrast, social influence on Turkish-minority adolescents' educational expectations is not uniform: only majority-group friends exert a significant (positive) influence. Our results emphasize that bridging social capital gained from social ties with majority-group members enhances ethnic minority adolescents' educational integration.
