Intergroup friendships and marriages are regarded as the most important indicators of immigrants’ social integration, as they represent the most intimate ties that can exist between minority and majority group members. Drawing on unique, large-scale, cross-national survey data, encompassing natives as well as Turkish, Moroccan, Pakistani and ex-Yugoslav migrants across several Western European countries, this book offers extensive analyses of intermarriage, as well as attitudes towards intermarriage and intergroup dating in general. Conceptualising the willingness or otherwise to marry outside one’s ethnic or religious group in terms of social distance, Social Integration and Intermarriage in Europe provides new evidence that different conceptions of family life, gender relations and religiosity are crucial for understanding why individuals can be reluctant to engage in intergroup relationships. With attention to the question of the role played by state policies in explaining immigrant social integration, the book explores differences across Western Europe and the ways in which each state regulates immigration and the accommodation of Islam. A detailed and rigorous study of attitudes to intermarriage, social integration and the role of the state, Social Integration and Intermarriage in Europe will appeal to policy makers and scholars of within the social sciences, with interests in migration, interethnic relations and social integration.
