Neither urban nor rural, yet idealized as the prototypical habitat of the American
middle
class,
suburbs stand betwixt and between in both a spatial and social sense. In the course
of the twentieth century, technological and socioeconomic developments have
transformed the function and meaning of
cities
and suburbs, as well as their relations. As
the twentieth century closed, suburban areas were home to more than one-half of all
Americans and much of the nation’s commerce and industry—what was once peripheral
was now central. The “edge cities” that cluster around the juncture of interstate
highways
and orbital beltways are the new multi-functional cores of the sprawling, poly-nucleated
metropolitan regions that dominate American society.
Beginning in the 1830s, transportation innovations facilitated the development o
residential enclaves for urban elites on the rural fringes of
Boston, New York,
Philadelphia, PA, Chicago, IL
and other American cities. Steam ferries, horse cars and
railroads allowed the wealthy to live in carefully landscaped, quasi-
astoral settings and
to commute to work in congested urban centers. Between 1890 and 1929, electric
streetcars and the
automobile
accentuated residential deconcentration and put suburban
homes within the reach of an emergent middle class. Cities frequently responded to the
growth of their unincorporated suburban frontiers by annexing them.
During the roaring 1920s, US suburbs grew at a faster rate than the cities they
surrounded and, for the first time, proved successful in resisting annexation. Unlike the
dense, vertical industrial metropoles of the nineteenth century, cities that experienced
their initial significant growth in the 1920s, such as Los Angeles and Atlanta, were
characterized by a low-rise, low-density landscape more suburban than urban. Although
the Great Depression and the Second World War ended this suburban boom,
decentralizing tendencies would return strongly after 1945.
The postwar period marked a quantitative and qualitative shift in the scale, intensity
and meaning of suburbanization. Twenty years of Depression and war created a
tremendous unmet demand for new housing, the vast majority of which was built on
undeveloped land outside city boundaries. The direction of growth was not merely the
case of the private sector responding to consumer preferences, but was shaped and
artially subsidized by public policy Government agencies, such as the Federal Housing
Authority (FHA) and the
Veterans
Administration (VA), subsidized mortgages for the
construction of new homes in suburban areas, while denying funds for repair or new
construction in many other urban
neighborhoods
. In subsidizing the risk borne by
lenders, the FHA and the VA allowed for long-term, low-cost mortgages that made
home-ownership cheaper than renting for families of even relatively modest means.
Fueled by abundant capital, home builders operating on vast economies of scale used
assembly-line techniques to mass produce millions of standardized, low-cost homes in
hitherto rural areas adjacent to major cities. One of the earliest and best known of these
developers was the Levitt Brothers of New York, whose trio of
“Levittowns”
in Long
Island, Pennsylvania, and New Jersey became a synonym for suburbia during the 1950s
and early 1960s. The Levitts’ approach to home building was echoed by developers in
virtually every metropolitan region in the country. American urbanism was completely
