Urban decay (also known as urban rot and urban blight) is the process whereby a previously functioning city, or part of a city, falls into disrepair and decrepitude. It may feature deindustrialization, depopulation or changing population, restructuring, abandoned buildings, high local unemployment, fragmented families, political disenfranchisement, crime, and a desolate, inhospitable city landscape.

Since the 1970s and 1980s, urban decay has been associated with Western cities, especially in North America and parts of Europe (mostly Britain and France). Since then, major structural changes in global economies, transportation, and government policy created the economic and then the social conditions resulting in urban decay.[2]

The effects counter the development of most of Europe and North America; in other continents, urban decay is manifested in the peripheral slums at the outskirts of a metropolis, while the city center and the inner city retain high real estate values and sustain a steadily increasing populace. In contrast, North American and British cities often experience population flights to the suburbs and exurb commuter towns; often in the form of white flight.[3] Another characteristic of urban decay is blight—the visual, psychological, and physical effects of living among empty lots, buildings and condemned houses. Such desolate properties are socially dangerous to the community because they attract criminals and street gangs, contributing to the volume of crime.

Urban decay has no single cause; it results from combinations of inter-related socio-economic conditions—including the city's urban planning decisions, tight rent control, the poverty of the local populace, the construction of freeway roads and rail road lines that bypass the area,[4] depopulation by suburbanization of peripheral lands, real estate neighborhood redlining,[5] and immigration restrictions.[6]


During the Industrial Revolution, from the late eighteenth century to the early nineteenth century, rural people moved from the country to the cities for employment in manufacturing industry, thus causing the urban population boom. However, subsequent economic change left many cities economically vulnerable. Studies such as the Urban Task Force (DETR 1999), the Urban White Paper (DETR 2000), and a study of Scottish cities (2003) posit that areas suffering industrial decline—high unemployment, poverty, and a decaying physical environment (sometimes including contaminated land and obsolete infrastructure)—prove "highly resistant to improvement".[7]

Changes in means of transport, from the public to the private—specifically, the private motor car—eliminated some of the cities' public transport service advantages, e.g., fixed-route buses and trains. In particular, at the end of World War II, many political decisions favored suburban development and encouraged suburbanization, by drawing city taxes from the cities to build new infrastructure for remote, racially restricted suburban towns.[citation needed]

The manufacturing sector has been a base for the prosperity of major cities. When the industries have relocated outside of cities, some have experienced population loss with associated urban decay, and even riots. Cut backs on police and fire services may result, while lobbying for government funded housing may increase. Increased city taxes encourage residents to move out.[8]

Rent control

Rent controls are often enacted due to public pressure and complaint regarding the cost of living. Proponents of rent controls argue that rent controls combat inflation, stabilize the economic characteristics of a city's population, prevent rent gouging, and improve the quality of housing.[9] It has been documented that rent control distorts the supply and demand relationship in housing markets which contributes to the rapid deterioration of the community and to urban blight and does not provide the supposed benefits its proponents promise.[10] Rent control contributes to urban blight by reducing new construction and investment in housing and deincentivizing maintenance.[11] If a landlord's costs to perform maintenance consume too large a proportion of revenue from rent, the landlord will feel pressure to drastically reduce or eliminate maintenance entirely. This effect has been observed in New York City as 29% of rent-controlled buildings were categorized as either deteriorated or dilapidated in contrast with 8% of non-rent-controlled housing.[12]


United States

Detroit's Michigan Central Station and its Amtrak connection went out of service in 1988, under pressure from increasing automobile dependency.

Historically in the United States, the white middle class gradually left the cities for suburban areas because of higher crime rates and perceived danger caused by African-American migration north toward cities after World War I (the Great Migration)—the so-called "white flight" phenomenon.[13]

Some historians differentiate between the first Great Migration (1910–1930), numbering about 1.6 million Black migrants who left mostly Southern rural areas to migrate to northern and midwestern industrial cities, and, after a lull during the Great Depression, a Second Great Migration (1940–1970), in which 5 million or more African-Americans moved, including many to California and various western cities.[14]

Between 1910 and 1970, Blacks moved from 14 states of the South, especially Alabama, Louisiana, Mississippi and Texas to the other three cultural (and census-designated) regions of the United States. More townspeople with urban skills moved during the second migration.[14] By the end of the Second Great Migration, African Americans had become an urbanized population. More than 80 percent lived in cities. A majority of 53 percent remained in the South, while 40 percent lived in the North and 7 percent in the West.[15]

From the 1930s until 1977, African-Americans seeking borrowed capital for housing and businesses were discriminated against via the federal-government–legislated discriminatory lending practices for the Federal Housing Administration (FHA) via redlining.[16][17] In 1977, the US Congress passed the Community Reinvestment Act, designed to encourage commercial banks and savings associations to help meet the needs of borrowers in all segments of their communities, including low- and moderate-income neighborhoods.[18][19][20]

Later urban centers were drained further through the advent of mass car ownership, the marketing of suburbia as a location to move to, and the building of the Interstate Highway System. In North America this shift manifested itself in strip malls, suburban retail and employment centers, and very low-density housing estates. Large areas of many northern cities in the United States experienced population decreases and a degradation of urban areas.[21]

Inner-city property values declined and economically disadvantaged populations moved in. In the U.S., the new inner-city poor were often African-Americans that migrated from the South in the 1920s and 1930s. As they moved into traditional white neighborhoods, ethnic frictions served to accelerate flight to the suburbs.[22]

United Kingdom

The burnt out shell of the former Savoy Hotel in Sandown on the Isle of Wight - Sandown is a town dominated by hotels, but the closure of many of them has driven tourists away, causing the buildings to fall into disuse and disrepair.

Britain experienced severe urban decay in the 1970s and 1980s exemplified by "Ghost Town" by The Specials a 1981 hit single. Major cities like Glasgow, the towns of the South Wales valleys, and some of the major industrial cities like Birmingham, Manchester, Liverpool, Newcastle, and east London, all experienced population decreases, with large areas of 19th-century housing experiencing market price collapse. Some seaside resort towns have also experienced urban decay towards the end of the 20th Century, due to the popularity of Package holidays to the continent.


Main article: Banlieue

Large French cities are often surrounded by areas of urban decay. While city centers tend to be occupied mainly by upper-class residents, cities are often surrounded by public housing developments, with many tenants being of North African origin (from former French colonies Morocco, Algeria and Tunisia), and recent immigrants.

From the 50s to the 70s, publicly funded housing projects resulted in large areas of mid to high-rise buildings. These modern "grands ensembles" were welcomed at the time, as they replaced shanty towns and raised living standards, but these areas were heavily affected by economic depression in the 80s.

The banlieues of large cities like Lyon, especially the northern Parisian banlieues, are severely criticized and forgotten by the country's territorial spatial planning administration. They have been ostracised ever since the French Commune government of 1871, considered as "lawless" or "outside the law", even "outside the Republic", as opposed to "deep France", or "authentic France", which is associated with the countryside.[23]

In November 2005, the French suburbs were the scene of severe riots sparked by the accidental electrocution of two teenagers in the northern suburbs of Paris, and fueled in part by the substandard living conditions in these areas. Many deprived suburbs of French cities were suddenly the scenes of clashes between youngsters and the police, with violence and numerous car burnings resulting in huge media coverage.

Today the situation remains generally unchanged; however, there is still a level of disparity. Some areas are experiencing increased drug trafficking, while some northern suburbs of Paris and areas like Vaulx-en-Velin are undergoing refurbishment and re-development.

Some previously mono-industrial towns in France know increasing criminality and decay, and decreasing population. The issue remains a divisive issue in French public politics.


Council houses in Scampia, Naples.

In Italy, one of the most well known case of urban decay is represented by the Vele di Scampia, a large public housing estate built between 1962 and 1975 in the Scampia neighbourhood of Naples. The idea behind the project was to provide a huge urban housing project, where hundreds of families could socialise and create a community. The design included a public transportation rail station, and a large park area between the two buildings. The planners wanted to create a small city model with large parks, playing fields, and other facilities.

However, various events led to a tremendous urban decay inside this project and in the surrounding areas. It all started with the 1980 earthquake, in Irpinia, which led many families, left homeless, to squat the flats inside the Vele.[24] This has caused a melting of different cultures together and, as often the case, illegality and abusiveness has grown rapidly. Things were made worse by the total lack of police presence, resulting in a deep bundling of the Camorra inside the area, which now controls drug trafficking, illegal street racing, gangs, and fencing operations.

Policy responses to urban decay

Pruitt–Igoe public housing, St. Louis, Missouri. In the 1950s, this urban renewal project was built; it failed and was razed in the 1970s.

The main responses to urban decay have been through positive public intervention and policy, through a plethora of initiatives, funding streams, and agencies, using the principles of New Urbanism (or through Urban Renaissance, its UK/European equivalent). Gentrification has also had a significant effect, and remains the primary means of a natural remedy.

United States

In the United States, early government policies included "urban renewal" and building of large-scale housing projects for the poor. Urban renewal demolished entire neighborhoods in many inner cities; in many ways, it was a cause of urban decay rather than a remedy.[6][25] These government efforts are now thought by many to have been misguided.[6][26]

For multiple reasons, some cities have rebounded from these policy mistakes. Meanwhile, some of the inner suburbs built in the 1950s and 60s are beginning the process of decay, as those who are living in the inner city are pushed out due to gentrification.[27]


In Western Europe, where undeveloped land is scarce and urban areas are generally recognised as the drivers of the new information and service economies, urban renewal has become an industry in itself, with hundreds of agencies and charities set up to tackle the issue. European cities have the benefit of historical organic development patterns already concurrent to the New Urbanist model, and although derelict, most cities have attractive historical quarters and buildings ripe for redevelopment.

In the inner-city estates and suburban cités, the solution is often more drastic, with 1960s and 70s state housing projects being totally demolished and rebuilt in a more traditional European urban style, with a mix of housing types, sizes, prices, and tenures, as well as a mix of other uses such as retail or commercial. One of the best examples of this is in Hulme, Manchester, which was cleared of 19th-century housing in the 1950s to make way for a large estate of high-rise flats. During the 1990s, it was cleared again to make way for new development built along new urbanist lines.
