Perceptual regions

Explanation:

Perceptual regions are also known as vernacular regions are the subjective ideas about the existence of a certain region, by its members or people outside of it. The people in the area have their own ideas about what their region is and what they share with other members, and sometimes people on the outside mark inhabitants of this region as members of the same group, with the same qualities.

Those are not regions seen on the map or limited to geographical markers. Perceptual regions are distinctive communities and ideas by which people form their identities, cultural belongings, and shared history.

For example, “Bible belt” is not the region on the map, but when mentioned people will know it refers to the southern part of the US in which people are most likely seen as Christians with conservative views.
