In contrast to the abstract cultural homogeneity of a formal culture region, a functional culture region may not be culturally homogeneous; instead, it is an area that has been organized to function politically, socially, or economically as one unit: a city, an independent state, a precinct, a church diocese or parish, a trade area or a farm. Functional culture regions have nodes or central points where the functions are coordinated and directed, such as city halls, national capitols, precinct voting places, parish churches, factories, and banks. In that sense, functional regions also possess a core-periphery configuration, in common with formal culture regions. Many functional regions have clearly defined borders that include all land under the jurisdiction of a particular urban government that is clearly delineated on a regional map by a line distinguishing between one jurisdiction and another.
