The first type is the formal region. It is characterized by a common human property, such as the presence of people who share a particular language, religion, nationality, political identity or culture, or by a common physical property, such as the presence of a particular type of climate, landform, or vegetation.
The second type of region is the functional region. It is organized around a node or focal point with the surrounding areas linked to that node by transportation systems, communication systems, or other economic association involving such activities as manufacturing and retail trading.
The third type of region is the perceptual region. It is a construct that reflects human feelings and attitudes about areas and is therefore defined by people’s shared subjective images of those areas.
