The Suburbanization of American Cities


Nationally, the postwar period saw a mass exodus of city residents into suburbs and the growth of low-density peripheral areas around cities. This trend was exacerbated by an increase in the use of private automobiles. In Atlanta streetcars operated from 1871 to 1948; the streetcar lines, such as the Nine Mile Trolley, connected several downtown neighborhoods. Changes in transportation in the 1950s, including the end of the streetcar and the rise in automobile ownership, necessitated changes in land-use patterns. Thus, in 1952, the Atlanta City Planning Commission proposed a network of highways that would allow commuters to reside further from the city center than ever before. In addition, the growing suburbanization of Atlanta increased the demand for large structures such as parking garages; to construct these garages, many historic structures downtown were demolished. Notably, most of the residents in Atlanta, and other cities, who migrated from downtown to the suburbs were white. This “white flight” in suburbanization is viewed by historians as an effort to maintain spatial segregation.
