broken windows theory, academic theory proposed by James Q. Wilson and George Kelling in 1982 that used broken windows as a metaphor for disorder within neighborhoods. Their theory links disorder and incivility within a community to subsequent occurrences of serious crime.

The theory

Prior to the development and implementation of various incivility theories such as broken windows, law enforcement scholars and police tended to focus on serious crime; that is, the major concern was with crimes that were perceived to be the most serious and consequential for the victim, such as rape, robbery, and murder. Wilson and Kelling took a different view. They saw serious crime as the final result of a lengthier chain of events, theorizing that crime emanated from disorder and that if disorder were eliminated, then serious crimes would not occur.

Their theory further posits that the prevalence of disorder creates fear in the minds of citizens who are convinced that the area is unsafe. This withdrawal from the community weakens social controls that previously kept criminals in check. Once this process begins, it feeds itself. Disorder causes crime, and crime causes further disorder and crime.

Scholars generally define two different types of disorder. The first is physical disorder, typified by vacant buildings, broken windows, abandoned vehicles, and vacant lots filled with trash. The second type is social disorder, which is typified by aggressive panhandlers, noisy neighbors, and groups of youths congregating on street corners. The line between crime and disorder is often blurred, with some experts considering such acts as prostitution and drug dealing as disorder while many others classify them as crimes. While different, these two types of disorder are both thought to increase fear among citizens.

The obvious advantage of this theory over many of its criminological predecessors is that it enables initiatives within the realm of criminal justice policy to effect change, rather than relying on social policy. Earlier social disorganization theories and economic theories offered solutions that were costly and would take a long time to prove effective. Broken windows theory is seen by many as a way to effect change quickly and with minimal expense by merely altering the police crime-control strategy. It is far simpler to attack disorder than it is to attack such ominous social ills as poverty and inadequate education.

The theory in practice: 1990s New York City

Broken windows theory had an enormous impact on police policy throughout the 1990s and remained influential into the 21st century. Perhaps the most notable application of the theory was in New York City under the direction of Police Commissioner William Bratton. He and others were convinced that the aggressive order-maintenance practices of the New York City Police Department were responsible for the dramatic decrease in crime rates within the city during the 1990s. Bratton began translating the theory into practice as the chief of New York City’s transit police from 1990 to 1992. Squads of plainclothes officers were assigned to catch turnstile jumpers, and, as arrests for misdemeanors increased, subway crimes of all kinds decreased dramatically. In 1994, when he became New York City police commissioner, Bratton introduced his broken windows-based “quality of life initiative.” This initiative cracked down on panhandling, disorderly behavior, public drinking, street prostitution, and unsolicited windshield washing or other such attempts to obtain cash from drivers stopped in traffic. When Bratton resigned in 1996, felonies were down almost 40 percent in New York, and the homicide rate had been halved.

Criticism and influence

Although popular in both academic and law-enforcement circles, broken windows theory is not without its critics. One line of criticism is that there is little empirical evidence that disorder, when left unchallenged, causes crime. To validate the theory in its entirety, it must be shown that disorder causes fear, that fear causes a breakdown of social controls (sometimes referred to as community cohesion), and that this breakdown of social controls in turn causes crime. Finally, crime must be shown to increase levels of disorder.

The strongest empirical support for the broken windows theory came from the work of political scientist Wesley Skogan, who found that certain types of social and physical disorder were related to certain kinds of serious crime. However, Skogan prudently recommended caution in the interpretation of his results as proof of the validity of the broken windows theory. Even this qualified support has been questioned by some researchers. In a reanalysis of Skogan’s data, political theorist Bernard Harcourt found that the link between neighborhood disorder and purse snatching, assault, rape, and burglary vanished when poverty, neighborhood stability, and race were statistically controlled. Only the link between disorder and robbery remained. Harcourt also criticized the broken windows theory for fostering “zero-tolerance” policies that are prejudicial against the disadvantaged segments of society.

In his attempt to link serious crime with disorder, criminal justice scholar Ralph Taylor found that no distinct pattern of relationships between crime and disorder emerged. Rather, some specific disorderly acts were linked to some specific crimes. He concluded that attention to disorder in general might be an error and that, while loosely connected, specific acts may not reflect a general state of disorder. He suggested that specific problems would require specific solutions. This seemed to provide more support for problem-oriented policing strategies than it did for the broken windows theory.

In short, the validity of the broken windows theory is not known. It is safe to conclude that the theory does not explain everything and that, even if the theory is valid, companion theories are necessary to fully explain crime. Alternatively, a more complex model is needed to consider many more cogent factors. Almost every study of the topic has, however, validated the link between disorder and fear. There is also strong support for the belief that fear increases a person’s desire to abandon disorderly communities and move to environments that are more hospitable. This option is available to the middle class, who can afford to move, but not to the poor, who have fewer choices. If the middle class moves out and the poor stay, the neighborhood will inevitably become economically disadvantaged. This suggests that the next wave of theorization about neighborhood dynamics and crime may take an economic bent.

sprawl or suburban sprawl

urban 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. 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 has been correlated with increased energy use, pollution, and traffic congestion and a decline in community distinctiveness and cohesiveness. 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.

During 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. 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. 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. 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. Suburban residents retained a connection to the city through their automobiles.

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. According to the U.S. Bureau of the Census, the causes of urban sprawl are divided equally between local population increases and lifestyle choices. For example, between 1970 and 1990, 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. 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, 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 1970 and 1990, but each area’s geographic extent grew by 24 percent, 55 percent, and 91 percent, respectively. The spatial footprints of major cities in the Midwest and the Northeast, such as Detroit, Michigan, and Pittsburgh, Pennsylvania, grew approximately 30 percent even as the cities experienced declines in population over the same period.

For many years, urban sprawl was thought to be an exclusively American problem; however, this phenomenon is occurring in several other countries. According to data collected in 2002 by the European Environment Agency, the population of a subset of European countries increased by only 6 percent between 1980 and 2000; however, the spatial footprint of built-up areas within these countries increased by 20 percent. The spatial footprints of some metropolitan areas, such as Palermo, Italy, expanded significantly more from the mid-1950s to the late 1990s. Palermo’s population rose 50 percent but its spatial footprint increased 200 percent over the period.

Worldwide, people are moving to cities. According to the United Nations Population Division, 29 percent of the world’s population lived in urban areas in 1950. By the late 2000s this figure had increased to about 49 percent. In developed countries this fraction was much higher. In the United States, for example, the urban population rose from roughly 64 percent in 1950 to about 81 percent in 2007. Similarly, Japan’s urban population increased from roughly 40 percent to about 66 percent over the same period. In contrast, less-affluent developing countries contain fewer urban residents. In India, for example, the urban population increased from 17 percent in 1950 to about 29 percent in 2007. Similarly, Egypt’s urban population rose from about 32 percent to approximately 43 percent over the same interval.

Causes

There are many factors that contribute to urban sprawl. As indicated by the statistics cited above, population increases alone do not account for increases in a metropolitan area’s urban extent. In many cases, urban sprawl has occurred in areas experiencing population declines, and some areas with rising populations experience little urban sprawl, especially in developing countries. Economic growth and globalization are often cited as the principal macroeconomic drivers of urban sprawl; however, increased affluence, attractive land and housing prices, and the desire for larger homes with more amenities (such as yards, household appliances, storage space, and privacy) play significant roles at the level of the individual. Many experts also believe that weak planning laws and single-use zoning also contribute to urban sprawl.

The construction of houses, utilities, and roads in the suburbs, along with the delivery of resources to suburban residents and workers, are integral components of the gross national product of developed countries. Because much of the growth in a metropolitan area occurs at the fringes, large amounts of resources and services are directed there. Construction at the “urban fringe” is increasingly characterized by a standardization of design. Many suburban housing tracts contain similar or identical models that sit on parcels with identical or nearly identical specifications. Standardization reduces costs, since materials (which often come from sources overseas) can be ordered in bulk, and quickens the pace of construction. Some urban planners and social scientists have linked this trend toward design standardization to the rising influence of globalization.

Many urban planners maintain that modern suburban zoning laws have done much to promote urban sprawl. In the United States such laws tend to rely on single-use zoning, a practice that restricts an area to the development of one particular land-use type (such as single-family residential, multifamily residential, commercial, institutional, and light industrial) in an effort to separate “incompatible” land uses from one another. After the U.S. Supreme Court upheld the constitutionality of zoning regulations in Village of Euclid v. Ambler Realty Company (1926), the practice was largely adopted by American municipalities. As a result of the court decision, the term Euclidean zoning became synonymous with single-use zoning. Despite the honourable intentions of Euclidean zoning, it discourages the development of walkable communities. Homes built deep within housing tracts are located far away from stores, schools, and employment areas. As a result, residents often depend on automobiles. In contrast, in older urban neighbourhoods, diverse land-use types are typically interspersed with one another.
