[[Urban sprawl]], also known as suburban sprawl, is a multifaceted concept, which includes the spreading outwards of a city and its [[suburb]]s to its outskirts to low-density, auto-dependent development on rural land, with associated design features that encourage [[car dependency]].<ref name="sprawlcity">{{usurped|1=[https://web.archive.org/web/20100105123334/http://www.sprawlcity.org/hbis/wis.html What is Sprawl?]}}. ''SprawlCity.org''. Retrieved on 2008-02-07.</ref> As a result, some critics argue that sprawl has certain disadvantages including longer transport distances to work, high [[Automobile dependency|car dependence]], inadequate facilities (e.g. health, cultural. etc.) and higher per-person infrastructure costs. Discussions and debates about sprawl are often obfuscated by the ambiguity associated with the phrase. 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 center), discontinuity (leapfrog development), segregation of uses, etc.<ref>{{Cite book |last=Jain |first=Shri V.
