An exurb (or alternately: exurban area) is an area outside the typically denser inner suburban area, at the edge of a metropolitan area, which has some economic and commuting connection to the metro area, low housing density, and growth. It shapes an interface between urban and rural landscapes holding a limited urban nature for its functional, economic, and social interaction with the urban center, due to its dominant residential character. [1] Exurbs consist of "agglomerations of housing and jobs outside the municipal boundaries of a primary city" [2] and beyond the surrounding suburbs. [3]

Definitions

The word exurb (a portmanteau of extra (outside) and urban) was coined by Auguste Comte Spectorsky, in his 1955 book The Exurbanites, to describe the ring of prosperous communities beyond the suburbs, that are commuter towns for an urban area. [4] In other uses the term has expanded to include popular extraurban districts which nonetheless may have poor transportation and underdeveloped economies due to distance from the urban center. [5] Exurbs can be defined in terms of population density across the extended urban area, for example "the urban core (old urban areas including Siming and Huli, where the population density is greater than 51 persons per ha), the suburban zone (old urban and new urban transitional zones including Haicang and Jimei, where the population density is greater than 8 persons per ha), and the exurban areas (newly urbanized areas including Tong'an and Xiang'an, where the population density is less than 8 persons per ha)". [6] The mixture of urban and rural environments raises ecological issues. [7] [6]

Since the Finding Exurbia report by the Brookings Institution in 2006, the term is generally used[ citation needed ] for areas beyond suburbs and specifically less densely built and populated than the suburbs to which the exurbs' residents commute. [9] To qualify as exurban, a census tract must meet three criteria: [9]

  1. Economic connection to a large metropolis.
  2. Low housing density: bottom third of census tracts with regard to housing density. In 2000, this was a minimum of 2.6 acres (1.1 hectares ) per resident.
  3. Population growth exceeding the average for its central metropolitan area.

These are based on published datasets. Alternative approaches include working with Oak Ridge National Laboratory LandScan data and GIS. [10]

Exurban areas incorporate a mix of rural development (e.g., farms and open space) and in places, suburban-style development (e.g., tracts of single-family homes, though usually on large lots). In long-settled areas, such as the U.S. Northeast megalopolis, exurban areas incorporate pre-existing towns, villages and smaller cities, as well as strips of older single-family homes built along pre-existing roads that connected the older population centers of what was once a rural area. The Brookings Institution listed exurban counties, defined as having at least 20% of their residents in exurban Census tracts. [9]

<span class="mw-page-title-main">Suburb</span> Human settlement within a metropolitan area

A suburb is an area within a metropolitan area which has a higher or lower population density and sometimes less detached housing. In many metropolitan areas suburbs rise in population during the day and are where most jobs are located; being major commercial and job hubs, many suburbs also exist as separate residential communities within commuting distance of a larger city. Suburbs can have their own political or legal jurisdiction, especially in the United States, but this is not always the case, especially in the United Kingdom, where most suburbs are located within the administrative boundaries of cities. In most English-speaking countries, suburban areas are defined in contrast to central city or inner city areas, but in Australian English and South African English, suburb has become largely synonymous with what is called a "neighborhood" in the U.S., but it is used in contrast with inner city areas.

<span class="mw-page-title-main">Metropolitan area</span> Administrative unit of a dense urban core and its satellite cities

A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories sharing industries, commercial areas, transport network, infrastructures and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.

Population density is a measurement of population per unit land area. It is mostly applied to humans, but sometimes to other living organisms too. It is a key geographical term.

<span class="mw-page-title-main">Commuting</span> Periodically recurring travel between ones place of residence and place of work, or study

Commuting is periodically recurring travel between one's place of residence and place of work or study, where the traveler, referred to as a commuter, leaves the boundary of their home community. Regarding occupation, it is also colloquially called the journey to work. By extension, it can sometimes be any regular or often repeated travel between locations, even when not work-related. The modes of travel, time taken and distance traveled in commuting varies widely across the globe. Most people in least-developed countries continue to walk to work. The cheapest method of commuting after walking is usually by bicycle, so this is common in low-income countries but is also increasingly practised by people in wealthier countries for environmental and health reasons. In middle-income countries, motorcycle commuting is very common.

<span class="mw-page-title-main">Conurbation</span> Group of settlements linked by continuous urban area

A conurbation is a region comprising a number of metropolises, cities, large towns, and other urban areas which, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area in which transportation has developed to link areas. They create a single urban labour market or travel to work area.

<span class="mw-page-title-main">Satellite city</span> Smaller municipality that is adjacent to a larger major city

A satellite city or satellite town is a smaller municipality or settlement that is part of a larger metropolitan area and serves as a regional population and employment center. It differs from mere suburbs, subdivisions and especially bedroom communities in that it has employment bases sufficient to support its residential population, and conceptually, could be a self-sufficient community outside of its larger metropolitan area. However, it functions as part of a metropolis and experiences high levels of cross-commuting.

<span class="mw-page-title-main">Urban sprawl</span> Expansion of auto-oriented, low-density development in suburbs

Urban sprawl is defined as "the spreading of urban developments on undeveloped land near a more or less densely populated 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 very dense urban planning. Sometimes the urban areas described as the most "sprawling" are the most densely populated. In addition to describing a special form of urbanization, the term also relates to the social and environmental consequences associated with this development. In modern times some suburban areas described as "sprawl" have less detached housing and higher density than the nearby core city. Medieval suburbs suffered from the loss of protection of city walls, before the advent of industrial warfare. Modern disadvantages and costs include increased travel time, transport costs, pollution, and destruction of the countryside. The revenue for building and maintaining urban infrastructure in these areas are gained mostly through property and sales taxes. Most jobs in the US are now located in suburbs generating much of the revenue, although a lack of growth will require higher tax rates.

<span class="mw-page-title-main">Suburbanization</span> Population shift from central urban areas into suburbs

Suburbanization (AE), or suburbanisation (BE), is a population shift from historic core cities or rural areas into suburbs, resulting in the formation of (sub)urban sprawl. As a consequence of the movement of households and businesses away from city centers, low-density, peripheral urban areas grow.

A city proper is the geographical area contained within city limits. The term proper is not exclusive to cities; it can describe the geographical area within the boundaries of any given locality. The United Nations defines the term as "the single political jurisdiction which contains the historical city centre. The term is synonymous with Central City in the United States which typically contains much of the lower income population. "

<span class="mw-page-title-main">Thessaloniki metropolitan area</span>

The Thessaloniki metropolitan area or larger urban zone (LUZ) is the complete area covered and directly influenced by Thessaloniki. The metropolitan area traditionally consisted of the municipality of Thessaloniki and its immediate surroundings, what is today referred to as the Thessaloniki urban area. However, since the mid to late 1990s, the areas surrounding the urban area, have succumbed to urban sprawl and what used to be agrarian communities are rapidly urbanizing and being developed into suburbs or exurbs. This is creating new problems for a region already facing issues such as pollution, traffic congestion and social ills.

<span class="mw-page-title-main">Inner suburb</span> Suburbs central to a metropolis

An inner suburb is a suburban community central to a large city, or at the inner city and central business district. The urban density is usually lower than the inner city or central business district, but higher than that of the city's rural–urban fringe, or exurbs.

The daily urban system (DUS) refers to the area around a city, in which daily commuting occurs. It is a means for defining an urban region by including the areas from which individuals commute. Daily Urban System is a concept first introduced by the American geographer Berry, and then introduced into Europe by the British geographer Hall.

<span class="mw-page-title-main">Commuter town</span> Urban community that is primarily residential, from which most of the workforce commutes out

A commuter town is a populated area that is primarily residential rather than commercial or industrial. Routine travel from home to work and back is called commuting, which is where the term comes from. A commuter town may be called by many other terms: "bedroom community", "bedroom town", "bedroom suburb" (US), "dormitory town", or "dormitory suburb" (Britain/Commonwealth/Ireland). In Japan, a commuter town may be referred to by the wasei-eigo coinage "bed town". The term "exurb" was used from the 1950s, but since 2006, is generally used for areas beyond suburbs and specifically less densely built than the suburbs to which the exurbs' residents commute.

<span class="mw-page-title-main">Functional area (France)</span> Statistical area in France

An aire d'attraction d'une ville is a statistical area used by France's national statistics office INSEE since 2020, officially translated as functional area in English by INSEE, which consists of a densely populated urban agglomeration and the surrounding exurbs, towns and intervening rural areas that are socioeconomically tied to the central urban agglomeration, as measured by commuting patterns. INSEE's functional area (AAV) is therefore akin to what is most often called metropolitan area in English.
