Voluntary segregation is almost as common an occurrence as involuntary segregation is. Often, immigrants coming to a new and foreign country will band together for mutual benefit, and to keep a sense of community in the new country. These can be called ethnic enclaves and can be formed by any community or people group.[10] Some well-known groups are Chinatowns, Little Italys and barrios. These localized phenomena also come in the form of ethnoburbs, which are essentially the same concept as an ethnic enclave, but specifically located in suburbs, rather than the traditional downtowns, where Chinatowns and Little Italys are usually based.
