![]() For example, the population of the metropolitan areas of Chicago, Illinois, Kansas City, Missouri, and Baltimore, Maryland, grew by 1 percent, 16 percent and 20 percent, respectively, between 19, but each area’s geographic extent grew by 24 percent, 55 percent, and 91 percent, respectively. On the other hand, in the metropolitan areas of the eastern and central United States, relatively modest population growth was also accompanied by significant spatial growth. For example, between 19, metropolitan areas in the western United States (such as Las Vegas, Nevada, Seattle, Washington, and Salt Lake City, Utah) experienced massive influxes of new residents that contributed to increases in their individual spatial footprints. Bureau of the Census, the causes of urban sprawl are divided equally between local population increases and lifestyle choices. Over time this migration to the suburbs, along with rising local populations, led to substantial increases in the geographic extent, or spatial footprint, of metropolitan areas in the United States.

Suburban residents retained a connection to the city through their automobiles. Some citizens moved to the suburbs to enjoy a lifestyle that was ostensibly closer to nature however, others moved to escape the congestion, crime, and noise of the city. Compared with land in the cities, suburban land was relatively inexpensive, and the homes constructed on this land afforded more space to their occupants than inner-city dwellings. At the same time, continued road-building projects, most notably the onset of the Interstate Highway System in 1956, and other infrastructure development made it possible to build homes on land that was previously inaccessible. In addition, by increasing the physical and environmental “footprints” of metropolitan areas, the phenomenon leads to the destruction of wildlife habitat and to the fragmentation of remaining natural areas.ĭuring the period of economic prosperity in the United States following the end of World War II, increased manufacturing output and new federal loan programs allowed many American citizens to purchase single-family homes and private automobiles. Urban sprawl has been correlated with increased energy use, pollution, and traffic congestion and a decline in community distinctiveness and cohesiveness. Urban sprawl is caused in part by the need to accommodate a rising urban population however, in many metropolitan areas it results from a desire for increased living space and other residential amenities. Urban sprawl, also called sprawl or suburban sprawl, the rapid expansion of the geographic extent of cities and towns, often characterized by low-density residential housing, single-use zoning, and increased reliance on the private automobile for transportation.
