Questions: Urban Geography and City Structure

Question 1

Which urban structure model best describes a city organized around multiple distinct focal points — an airport district, a university area, and a central business district — rather than a single center?

• A. Burgess's concentric zone model
• B. Hoyt's sector model
• C. Harris and Ullman's multiple nuclei model
• D. Von Thünen's land use model

Answer: (C)

Harris and Ullman's multiple nuclei model explicitly accounts for cities that have several centers of activity rather than one CBD. Burgess assumes a single central core with expanding rings; Hoyt assumes a single center with wedge-shaped sectors along transit lines; Von Thünen is an agricultural land use model, not an urban structure model.

Question 2

Burgess's concentric zone model is a universal description of how most cities are structured.

• T. True
• F. False

Answer: False

The concentric zone model was developed from 1920s Chicago and is an ideal type — a simplified, hypothetical construct — not a universal law. Cities in the Global South often display inverted patterns, with wealthier residents near the center and informal settlements at the periphery, precisely the opposite of Burgess's prediction. The model is a useful analytical starting point, not an empirical claim about all cities.

Question 3

Why do cities in the Global South often display urban structures that differ from the patterns predicted by classic North American urban models?

Model answer: Classic models were derived from North American cities shaped by car-based suburbanization, mortgage markets, and white flight. In many Global South cities, colonial-era planning favored elite central enclaves, land markets work differently, transportation infrastructure is limited, and rapid rural-to-urban migration created peripheral informal settlements rather than affluent suburbs.

Urban structure reflects the historical, economic, and institutional context in which cities grew. North American suburbanization was driven by specific mid-20th century policies (highway construction, mortgage subsidies, racial segregation). Cities that developed under colonial rule, or grew rapidly in the late 20th century without similar state infrastructure, produced different spatial patterns.
