Perceptual regions are areas that are defined by the way people perceive them, rather than by any objective criteria. They can be based on cultural, historical, or psychological factors.

The state of Oregon is a perceptual region because people tend to think of it as a distinct area with its own unique identity. The city of Houston is also a perceptual region, as is San Antonio. The Dallas-Fort Worth Metroplex is a perceptual region that includes the cities of Dallas and Fort Worth, as well as the surrounding suburbs. The Rich Part of Dallas is a perceptual region that refers to the affluent areas of the city.

Metropolis is not a perceptual region. It is a general term that refers to a large city.
