This Chicago School model suggests that cities grow steadily outward from the urban core or central business district. Surrounding this commercial core is a “zone in transition,” with factories and warehouses. Beyond this comes the tenements and apartments of the working class, next the middle-class neighborhoods of larger homes, and ultimately the affluent commuter zones.
How well has this model — or, really, any model — held up over the past century of urban growth?
