Cultural area

In anthropology and geography, a cultural region, cultural sphere, cultural area or culture area refers to a geographical area with one relatively homogeneous human activity or complex of activities (culture). These are often associated with an ethnolinguistic group and the territory it inhabits. Specific cultures often do not limit their geographic coverage to the borders of a nation state, or to smaller subdivisions of a state. Cultural "spheres of influence" may also overlap or form concentric structures of macrocultures encompassing smaller local cultures. Different boundaries may also be drawn depending on the particular aspect of interest, such as religion and folklore vs. dress and architecture vs. language.

Cultural areas are not considered equivalent to Kulturkreis (Culture circles).

A culture area is a concept in cultural anthropology, in which a geographic region and time sequence (age area) is characterized by substantially uniform environment and culture. The concept of culture areas was originated by museum curators and ethnologists during the late 1800s as means of arranging exhibits. Clark Wissler and Alfred Kroeber further developed the concept on the premise that they represent long-standing cultural divisions. The concept is criticized by some, who argue that the basis for classification is arbitrary. But other researchers disagree and the organization of human communities into cultural areas remains a common practice throughout the social sciences. The definition of culture areas is enjoying a resurgence of practical and theoretical interest as social scientists conduct more research on processes of cultural globalization.

A formal culture region is an area inhabited by people who have one or more cultural traits in common, such as language, religion, or system of livelihood. It is an area relatively homogeneous with regard to one or more cultural traits. The geographer who identifies a formal culture region must locate cultural borders. Because cultures overlap and mix, such boundaries are rarely sharp even if only a single cultural trait is mapped so there are cultural border zones rather than lines. The zones broaden with each additional cultural trait that is considered because no two traits have the same spatial distribution. As a result, instead of having clear borders, formal culture regions reveal a center or core where the defining traits are all present. Away from the central core, the characteristics weaken and disappear. Thus, many formal culture regions display a core-periphery.
