translate English to French: Different strategies are possible to deal with the interaction between immigrants and host communities: one is segregation, consisting in separating migrant communities from the rest of the population; another one is assimilation of the immigrant population to the host community; finally there is multiculturalism, where different cultural models coexist and are accepted.
Plusieurs stratégies peuvent être envisagées pour organiser les relations entre ces populations: la ségrégation, qui consiste à séparer les populations immigrées du reste de la population, leur assimilation au sein de la population d'accueil, et enfin le multiculturalisme, c'est-à-dire la coexistence et l'acceptation réciproque de plusieurs modèles culturels.
