(This is not the same as Urban Decline)
is a process by which a city, or a part of a city, falls into a state of disrepair. It is characterized by depopulation, property abandonment, high unemployment, fragmented families, political disenfranchisement, crime, and desolate and unfriendly urban landscapes.
Urban decay was associated with Western cities, especially North America and parts of Europe during the 1970s and 1980s . During this time period major changes in global economies, Transportation , and government policies created conditions that fostered urban decay'' Urban Sores: On the Interaction Between Segregation, Urban Decay, and Deprived Neighbourhoods '' By Hans Skifter Andersen. ISBN 0754633055. 2003..
Although not uniquely a North American experience, the effects of urban decay run counter to the development patterns found in most cities in Europe and the rest of the world, where Slum s are usually located on the outskirts of major metropolitan areas while the City Center and Inner City retain high real estate values and a steady or increasing population. In contrast, North American cities often experience an outflux of population to city Suburbs or Exurbs , as in the case of White Flight , and can lead to phenomena such as Squatting '' Crabgrass Frontier: The Suburbanization of the United States '' by Professor Kenneth T Jackson (1987).
There is no single cause of urban decay, though it may be triggered by a combination of interrelated factors, including and Xenophobia of the 1920s." Page 140 and Racial Discrimination .

Since antiquity some people have chosen to live in cities Cities and Economic Development: From the Dawn of History to the Present By Paul Bairoch. ISBN 0226034666 Page 21. The earliest well documented cities are found in the Middle East around 3500 B.C. just after the dawn of agriculture. for financial, social, religious or cultural reasons. Urban areas encourage the economical use of Infrastructure , Transportation and space. Urban areas offer the widest ''variety'' of opportunities for education and financial betterment. They are the meeting places where business is conducted and goods are exchanged. They are the ports of entry for immigrants and the seats of power for governments. Urban places are held together by the human desire to form societies, celebrate culture and establish meaningful social relations. Cities are the essential element of most civilizations. The very word "civilization" shares the same root as "city."
During the Industrial Revolution , people moved from the countryside into cities to find employment in the manufacturing sector. Industrial manufacturing was largely responsible for the population boom cities experienced during this time period.
Industrial manufacturing and the failures of city planning to keep up with the sudden changes during the late 19th and first part of the 20th century contributed to a poor and unhealthy urban environment. The population of cities increased dramatically and the infrastructure that was in place was visibly inadequate.
Changes in transportation (specifically the private motor car) and communications eliminated much of the cities' advantages. With the end of World War II in particular many political decisions were employed that favored suburban development that further encouraged suburbanisation. Such decisions have drawn the financial resources from the cities in favour of providing infrastructure for remote suburban areas. Racial Discrimination , in this context known as " White Flight " in the United States , also played a part, as many chose to abandon cities and take part in an Urban Sprawl .
After World War Two, Western economies lifted tariffs and Outsourced most Manufacturing . During the change from a manufacturing to a service-based economy, the need for centralisation, and thus cities, has been reduced somewhat. Jobs no longer had to be centralised, and private motor transportation was growing in availability. Even for manufacturing workers, the process of suburbanisation was attractive because it allowed workers work at their factories, while commuting between their place of work and their larger suburban homes.
In the United States, the federal government aided the suburbanization process by mandating Discriminatory Lending Practices through the FHA in the form of Redlining ''Principles to Guide Housing Policy at the Beginning of the Millennium'', Michael Schill & Susan Wachter, Cityscape "Racial" Provisions of FHA Underwriting Manual, 1938 Recommended restrictions should include provision for the following ...
Prohibition of the occupancy of properties ...Schools should be appropriate to the needs of the new community and they should not be attended in large numbers by '''inharmonious racial groups'''. With Revisions to February, 1938 (Washington, D.C.), Part II, Section 9, Rating of Location.. Later, under President Dwight D. Eisenhower urban centers were drained further through the building of the Interstate Highway System . In North America this shift has 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 have experienced population decreases and a degradation of urban areas. Urban Decline and the Future of American Cities By Katharine L. Bradbury, Kenneth A. Small, ., Anthony Downs Page 28. ISBN 0815710534Ninety-five percent of cities with populations greater than 100,000 people in the US lost population between 1970 and 1975. Inner-city property values declined and economically disadvantaged populations moved in. In the U.S., the new inner-city poor were often black African-Americans who were migrated from the south in the 20s and 30s. As they moved into traditional white European-American neighborhoods, ethnic frictions served to accelerate flight to the suburbs. White Flight: Atlanta and the Making of Modern Conservatism
In Western Europe the experience differs in that the effect was often unknowingly assisted by public sector policies designed to clear 18th and 19th century slum areas and movements of people out into state subsidised lower density suburban housing.
On continental Europe and Oceania the historical core of major cities usually remains relatively affluent; it is generally the inner city districts and the edge of town suburbs made up of single-class state subsidised housing, such as the French 'cités' and British ' Council Estates ', which suffer the worst decay and blight. Simple economies of land mean that extremely low density housing in Europe is not practical due to higher population densities.

The Car manufacturing sector was the base for Detroit 's prosperity and employed the majority of its residents. When this industry began relocating outside of the city, it experienced population loss with associated urban decay, particularly after the 1967 Riots . In 1950 the city's population was, according to US census, around 1.85 million; by 2003 this had declined to 911,000, a loss of nearly 940,000 people (52%).
Britain experienced severe urban decay in the 1970s and 1980s. Major cities like Glasgow in Scotland, the towns of the South Wales valleys, and the major English cities like Birmingham , Manchester , Liverpool , Newcastle , and the East of London all experienced population decreases with very large areas of 19th-century housing experiencing market price collapse.
Large French cities are often surrounded by decayed areas. While the city center tends to be occupied mostly by middle- as well as upper-class residents, the city is often surrounded by very large mid to high-rise housing projects. The concentration of poverty and crime radiating from the developments often cause the entire suburb to fall into a state of urban decay as more affluent citizens seek housing in the city, or further out in semi-rural areas. In early November 2005, the decaying northern suburbs of Paris were the scene of severe Riots sparked in part by the substandard living conditions in public housing projects.
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 as its UK / European equivalent). The importance of Gentrification should not be underestimated and remains the primary means of a 'natural' remedy.
In the United States, early government policies included " has renewed and restored some of these neighborhoods. Meanwhile some of the inner suburbs built in the 1950s and 60s are beginning the process of decay. '' The Decline of Inner Suburbs: The New Suburban Gothic in the United States '' By Thomas J. Vicino..
In Western Europe, where land is much less in supply and urban areas are generally recognised as the drivers of the new information and service economies, Urban Regeneration has become a quasi 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 suburban estates and cités the solution is often more drastic with 1960/70 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. The area is held up as an excellent example of Urban Renaissance.
