Concentric circle model

Explanation:

The concentric model was proposed by Burgess. This model defines different social people to live in an urban area. This is a very famous model related to metropolitan cities for development. Many of the social groups are based on their socioeconomic status that stands from central part distance to downtown.

This model is called the concentric model because it defined all social groups in the shapes of the ring from the center part to the outer part. It is also called the Burgess model. The human geography and urban geography involve it in the development of urban metropolitan cities.
