Acculturation of host individuals: immigrants and personal networks

There has been a vast amount of research on the changes experienced by immigrants, but little is known about the changes experienced by host individuals. This article focuses on the role of host individuals in the networks of relations between immigrant populations and the communities from the dominant culture, as well as the changes experienced by host individuals because of their continuous contact with immigrants. This research applied a network approach to the study of the acculturation of host individuals. Two independent studies were carried out: a systematic analysis of the personal networks of Argentinean (n = 67), Ecuadorian (n = 59), Italian (n = 37) and German (n = 37) residents in Seville and Cadiz (Spain) (Study 1); and an ethnographic study with human service workers for Latin American immigrants in Boston (USA) (Study 2). With two different strategies, the role of host individuals in personal networks of foreigners in the United States and Spain was analyzed. The results show that host individuals tend to have less centrality than compatriots, showing an overall secondary role in the personal networks of immigrants. The lowest average centrality was observed in recent and temporal migrants, whereas the highest corresponded to the individuals with more time of residence in Spain. The personal networks of human service providers in the United States vary in ethnic composition and in their structural properties, and therefore shape different types of integrative bridges for immigrants.
