The first effective settlers of Anglo America created its English-rooted charter culture to which other, later immigrant groups were expected to conform. Assimilation or acculturation has not been complete, and areal expressions of ethnic differentiation persist in America in the form of ethnic islands, provinces, or regional concentrations. French Canadian, black, Amerindian, Hispanic, Asian American, and other, smaller groups display recognizable areal presences. Among immigrant groups, those concentrations may result from cluster and chain migration.
