The urban model characterized by circular rings around a central business district is known as the Concentric Zone Model. Which model name corresponds to this description?

• A. Concentric Zone Model
• B. Sector Model
• C. Multiple Nuclei Model
• D. Peripheral Model

Answer: (A)

The idea being tested is how a city grows outward in circular layers from its center. This pattern is the Concentric Zone Model, which envisions the central business district at the core and successive circular rings around it representing different land uses and social groups. As distance from the center increases, the rings typically transition from newer, more transitional areas to more stable, residential zones, eventually reaching outer suburban areas. Understanding why this model fits: it treats urban structure as a series of nested circles, with each ring representing a distinct zone that reflects how accessibility and land value change with distance from the CBD. This contrasts with other models that describe cities expanding along spokes or into multiple centers, such as sectors extending outward in wedges, multiple nuclei with several activity hubs, or peripheral growth surrounding a core with edge cities. In those cases, the arrangement isn’t strictly circular around a single center, which is why the ringed pattern points to the Concentric Zone Model.
