Multiculturalism

Multiculturalism relates to communities containing multiple cultures. The term is used in two broad ways, either descriptively or normatively.

As a descriptive term, it usually refers to the simple fact of cultural diversity: it is generally applied to the demographic make-up of a specific place, sometime at the organizational level, e.g. schools, businesses, neighbourhoods, cities, or nations.
