Who proposed a four-stage model of the evolution of the American urban system?

• A. Borchert, John
• B. Burgess, E. W.
• C. Hoyt, Homer
• D. Ullman, J.

Answer: (A)

John Borchert proposed this four-epoch view of how the American urban system evolved, tying city growth directly to changes in transportation technology. He argued that each era brought a new pattern of where cities grew and how they connected to one another. In the Sail-wagon epoch, sailing ships and wagons kept urban growth near ports and along rivers. The Iron Horse epoch, with the spread of steam rail, linked inland markets and created new inland urban centers. The Steel Rail epoch expanded rail networks further, intensifying connections along major corridors and reshaping the distribution of cities. Finally, the Auto-Air-Amenity epoch, dominated by automobiles and air travel, accelerated suburbanization and metropolitan growth around highways and airports, transforming the geographic layout of the urban system. This perspective focuses on temporal shifts in transportation driving urban change, unlike Burgess’s concentric zones, Hoyt’s sector model, or Ullman’s spatial interaction/multiple-nuclei ideas, which describe internal city structure or separate theories of location and land use.
