Which geographer is associated with the Sector Model, which explains growth in sectors extending from the CBD along transportation corridors?

• A. Homer Hoyt
• B. Ernst Griffin
• C. Chauncey Harris
• D. Edward Ullman

Answer: (A)

The sector growth idea is built around emphasis on accessibility along transportation routes. Homer Hoyt proposed that cities expand outward from the central business district in wedge-shaped sectors that follow rail lines and main roads. Because land value and desirability rise along these corridors, development concentrates in those sectors, creating distinct wedges of growth rather than uniform rings around the core. This contrasts with the concentric-zone idea, which imagines rings around the CBD, or the multiple-nuclei idea, which centers growth around several nodes. The other names are tied to different models—Griffin and Ford described a Latin American city form, while Harris and Ullman outlined the multiple-nuclei model. So the geographer associated with the Sector Model is Homer Hoyt.
