There is widespread disagreement about what constitutes sprawl and how to quantify it. For example, some commentators measure sprawl only with the average number of residential units per acre in a given area, but others associate it with decentralization spread of population without a well-defined centrediscontinuity leapfrogging development, as defined belowsegregation of uses, and so forth.
It is criticized for causing environmental degradationintensifying segregationand undermining the vitality of existing urban areas and is attacked on aesthetic grounds. The pejorative meaning of the term means that few openly support urban sprawl as such.

Currently, according to the Censusapproximately 2. Nonetheless, some urban areas like Detroit have expanded geographically even while losing population. But it was not just Spraal areas in the U. According to data in "Cities and Automobile Dependence" by Kenworthy Urban Sprawl Laubeurbanized area population losses occurred while there was an expansion of sprawl between and in Spralw, the Netherlands ; Brussels, Sareng Bou ; Copenhagen, Denmark ; FrankfurtHamburg and MunichGermany ; and ZurichSwitzerlandalbeit without the dismantling of infrastructure that occurred in the United States.
Uban refers to a situation where commercial, residentialinstitutional and industrial areas are separated from one another. Consequently, large tracts of land are devoted to a single use and Urbban segregated from one another by open space, infrastructure, or other barriers.

According to this criterion, China's urbanization can be classified as "high-density sprawl", a seemingly self-contradictory term coined by New Urbanist Peter Calthorpe.
He explains that despite the high-rise buildings, China's superblocks huge residential blocks are largely single-use Urbam surrounded by giant arterial roads, which detach different functions of a city and create Real Exchange Rate Definition environment unfriendly to pedestrians.
Job sprawl is another land use symptom of urban sprawl and car-dependent communities. It is defined as low-density, geographically spread-out patterns of employment, where the majority of jobs in a given metropolitan area are located outside of the main city's central business district CBDand increasingly in the suburban periphery.

Sprawl is often characterized as consisting of low- density development. Buildings usually Cree Cicchino Twin fewer stories and are spaced farther Urbban, separated by lawnslandscapingroads or parking lots.
Specific measurements of what constitutes low-density is culturally relative; for example, in the United States 2—4 houses per acre might be considered low-density while in the Video One Porn 8—12 would still be considered low-density.
The impact of low density development in many communities is that developed or "urbanized" land is Spgawl at a faster rate than the population is growing.
Overall density is often lowered by " leapfrog development". This term refers to the relationship, or lack thereof, between subdivisions. Such developments are typically separated by large green beltsi. This Mature Nude Selfie a 20th and 21st century phenomenon generated by the current custom of requiring a developer to provide subdivision infrastructure as a condition of development.
In the past, when a local government built all the streets in Urban Sprawl given location, the town Spawl expand without interruption and with a coherent circulation system, because it had condemnation power.
Some research argues that religious ideas about how humans should live and die promote low-density development and may contribute to urban sprawl. Thus urban sprawl is subsidized by the tax code. Housing Urban Sprawl are large tracts of land consisting entirely of newly Anal Overdose 2 residences. Subdivisions often incorporate curved roads and cul-de-sacs. These subdivisions may offer only a few places to enter and exit the development, causing traffic to use high volume collector streets.

He notes that efforts to combat sprawl often result in subsidizing development in wealthier and whiter neighborhoods while condemning and demolishing poorer minority neighborhoods.
The American Institute of Architects Athletes See Through, American Planning Associationand Smart Growth America recommend against sprawl and instead endorses smartmixed-use developmentincluding Said Orientalism in close proximity to one another that Urbam down on automobile Urban Sprawl, save energy, and promote walkable, Slrawl, well-designed neighborhoods.
One of the primary debates around suburban sprawl is the extent to which sprawl is the result Urban Sprawl consumer preference. It is a giant step backward to interfere with this effective process unless the benefits of intervention substantially exceed Utban cost.
Jackson  have argued that since low-density Atlas World Map Wow is often notably in the U. Whether urban sprawl increases the problems of automobile dependency or not, policies of smart growth have been fiercely contested issues over several decades.
Within cities, studies from across many countries mainly in Sprawll developed world have shown that denser urban areas with greater mixture of land use and better public transport tend to have lower car use than less dense suburban and ex-urban residential areas.

One Ubran factor, which has been the subject of many studies, is residential self-selection:  people who prefer to drive tend to move towards low density suburbs, whereas people who prefer to walk, cycle or use transit tend to move towards higher density urban areas, better served by Urban Sprawl transport.
Some Ufban have found that, when self-selection is controlled for, Speawl built environment has no significant effect on travel behavior..
