What does the Harris-Ullman Multi-Nuclei Model propose?

• A. A city has a single central business district
• B. A city has multiple centers of activity rather than a single CBD
• C. The city is arranged in concentric rings
• D. The city has sectors along routes

Answer: (B)

The idea being tested is that cities grow around several centers of activity rather than one central business district. The Harris-Ullman Multi-Nuclei Model proposes that urban areas develop around multiple hubs, or nuclei, each attracting different land uses because of accessibility, competition, and specialized functions. As cities expand and transportation improves, new centers form around airports, universities, shopping districts, industrial parks, or major transit junctions, creating a network of activity nodes linked by roads and transit. This explains why large metro areas often have several employment centers and commercial clusters spread across the region instead of a single core dominating the city. It contrasts with models that depict a single core with rings or sectors extending outward, illustrating a polycentric urban pattern.
