There are three basic types of regions. There are formal, functional, and vernacular regions. The formal region is used to outline governmental, physical, cultural, and economic areas. The functional regions are used for service areas. Finally, the vernacular are constructed by peoples perception.
A functional region is an area defined by interactions and connections between a central point and surrounding locations. It is characterized by a hub or node that serves as a focal point for economic, social, or cultural activities, with the influence of this central point diminishing as distance from it increases. This type of region is organized around the flow of goods, services, and information.
The two basic types of regions are formal regions, which are defined by official boundaries such as countries or states, and functional regions, which are defined by a common function or activity that occurs within the region, such as a metropolitan area or a transportation network.
