What is Concentric Circle growth also known as?

• A. Sector Model
• B. Multiple Nuclei Model
• C. Burgess Model
• D. Urban Realms Model

Answer: (C)

Concentric circle growth describes cities expanding in circular bands around the central business district. This idea was proposed by Ernest Burgess in 1925, forming the Burgess Model. In this model, the city develops in rings with distinct land use and populations: the core business district at the center, then a transition zone with industry and poorer housing, followed by zones of working-class housing, better residences, and an outer commuter belt. As the city grows, activity and people move outward into the next ring, creating those circular layers.

Other models describe growth differently. The Sector Model envisions wedges or sectors radiating from the center along transportation routes, the Multiple Nuclei Model posits several distinct centers of activity rather than a single ring, and the Urban Realms Model describes multiple semi-autonomous cities or realms within a metro area. The concentric rings idea, by contrast, is specifically about growth in circular layers around the CBD, which is why this model is the best fit.
