Which of the following is NOT a zone listed in the Concentric Zone Model?

• A. Rural Zone
• B. Residential Zone
• C. Transitional Zone
• D. Commuter Zone

Answer: (A)

Cities grow in circles around the central business district, with five classic zones arranged outward: the central business district at the center, then the zone in transition, followed by the working-class zone, the residential zone, and finally the commuter zone. A Rural Zone does not appear as one of these rings; it lies outside the urban concentric pattern rather than being a defined ring within the model. That’s why it’s not listed as a zone in the Concentric Zone Model. The other options correspond to actual rings in the model: the zone in transition (inner, mixed-use area), the residential zone (housing for a range of incomes), and the commuter zone (outer suburbs).
