Urban decay
Urban decay (also known as urban rot, urban death or urban blight) is the sociological process by which a previously functioning city, or part of a city, falls into disrepair and decrepitude. There is no single process that leads to urban decay. Urban decay can include the following aspects: Industrialization Deindustrialization Gentrification Population decline or overpopulation Counterurbanization Economic Restructuring Multiculturalism Abandoned buildings or infrastructure High local unemployment Increased poverty Fragmented families Low overall living standards or quality of life Political disenfranchisement Crime (e.
Urban sprawl
Urban sprawl (also known as suburban sprawl or urban encroachment) is defined as "the spreading of urban developments (such as houses and shopping centers) on undeveloped land near a city". Urban sprawl has been described as the unrestricted growth in many urban areas of housing, commercial development, and roads over large expanses of land, with little concern for urban planning. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development.
White flight
White flight or white exodus is the sudden or gradual large-scale migration of white people from areas becoming more racially or ethnoculturally diverse. Starting in the 1950s and 1960s, the terms became popular in the United States. They referred to the large-scale migration of people of various European ancestries from racially mixed urban regions to more racially homogeneous suburban or exurban regions. The term has more recently been applied to other migrations by whites, from older, inner suburbs to rural areas, as well as from the U.
Downtown
Downtown is a term primarily used in North America by English speakers to refer to a city's sometimes commercial, cultural and often the historical, political and geographic heart. It is often synonymous with its central business district (CBD). Downtowns typically contain a small percentage of a city’s employment. In some metropolitan areas it is marked by a cluster of tall buildings, cultural institutions and the convergence of rail transit and bus lines. In British English, the term "city centre" is most often used instead.
Black flight
Black flight is a term applied to the migration of African Americans from predominantly black or mixed inner-city areas in the United States to suburbs and newly constructed homes on the outer edges of cities. While more attention has been paid to this since the 1990s, the movement of black people to the suburbs has been underway for some time, with nine million people having migrated from 1960 to 2000. Their goals have been similar to those of the white middle class, whose out-migration was called white flight: newer housing, better schools for their children, and attractive environments.
Suburbanization
Suburbanization, or suburbanisation, is a population shift from central urban areas into suburbs, resulting in the formation of (sub)urban sprawl. As a consequence of the movement of households and businesses out of the city centers, low-density, peripheral urban areas grow. Sub-urbanization is inversely related to urbanization (urbanisation), which denotes a population shift from rural areas into urban centers. Many residents of metropolitan regions work within the central urban area, but live outside of it, in satellite communities called suburbs, and commute to work by car or mass transit.
Terraced house
A terrace or terraced house (UK) or townhouse (US) is an architectural term for a form of medium-density housing that first started in 16th century Europe with a row of joined houses sharing side walls. In the United States and Canada these are known as row houses or row homes, commonly found in older cities such as Philadelphia, Baltimore, and Toronto. Terrace housing can be found worldwide, though it is quite common in Europe and Latin America, and many examples can be found in the United Kingdom, United States, Canada, and Australia.
Concentric zone model
The concentric zone model, also known as the Burgess model or the CCD model, is one of the earliest theoretical models to explain urban social structures. It was created by sociologist Ernest Burgess in 1925. Based on human ecology theory done by Burgess and applied on Chicago, it was the first to give the explanation of distribution of social groups within urban areas. This concentric ring model depicts urban land usage in concentric rings: the Central Business District (or CBD) was in the middle of the model, and the city is expanded in rings with different land uses.
Walkability
In urban planning, walkability is the accessibility of amenities by foot. It is based on the idea that urban spaces should be more than just transport corridors designed for maximum vehicle throughput. Instead, it should be relatively complete livable spaces that serve a variety of uses, users, and transportation modes and reduce the need for cars for travel. The term "walkability" was primarily invented in the 1960s due to Jane Jacobs' revolution in urban studies.
Affordable housing
Affordable housing is housing which is deemed affordable to those with a household income at or below the median as rated by the national government or a local government by a recognized housing affordability index. Most of the literature on affordable housing refers to mortgages and a number of forms that exist along a continuum – from emergency homeless shelters, to transitional housing, to non-market rental (also known as social or subsidized housing), to formal and informal rental, indigenous housing, and ending with affordable home ownership.
