They serve to identify and categorize individuals within a single society and to separate peoples and nations of different languages and faiths. By their pronunciation and choice of words, we may easily recognize districts of origin and educational levels of speakers of our own language. In some societies, religion may serve as a similar identifier of individuals and groups who observe distinctive modes of rhythms of life dictated by their separate faiths. Both language and religion are the transmitters of culture as well as its identifiers.
Both have distinctive spatial patterns—reflecting past and present processes of spatial interaction and diffusion—that are basic to the recognition of world culture realms. Although language and religion are important and evident components of spatial cultural variations, they are only part of the total complex of cultural identities that set off different social groups. In most of the cases, all over the world, ethnicity is still the most important identifier of the individuals, communities, groups and nations.
