There is a common assumption that immigrants contribute significantly to the breakdown of social cohesion. However, researchers and policymakers find that, on the contrary, immigrants contribute much to their adopted societies economically, socially, culturally and politically. This volume includes a variety of key works which explore this relationship between migration and social cohesion. The articles by some of the foremost writers in the field cover models and frameworks of immigrant incorporation, debates in multicultural policy, immigrant and ethnic minority political participation, citizenship, entrepreneurship and language and sociocultural adaptation.This authoritative collection will be of interest to students and professional researchers in sociology and anthropology, political science, cultural studies and migration and ethnic studies.
