Census-designated place 269771 223771458 2008-07-05T18:48:11Z Kyle the bot 3115531 robot Modifying: [[pt:Região censitária]] A '''census-designated place''' ('''CDP''') is a type of [[Place (United States Census Bureau)|place]] (a concentration of population) identified by the [[United States Census Bureau]] for statistical purposes. CDPs are delineated for each decennial census as the statistical counterparts of [[incorporated place]]s such as [[city|cities]], [[town]]s and [[village]]s. CDPs are communities that lack separate municipal government, but which otherwise physically resemble [[municipal corporation|incorporated]] places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name but are [[unincorporated area|not legally incorporated]] under the laws of the state in which they are located. The boundaries of a CDP have no legal status.<ref>[http://www.census.gov/geo/www/cob/pl_metadata.html#cdp United States Census Area Description]</ref> ==History== The Census Bureau reported data for some unincorporated places as early as the [[U.S. Census#Seventh Census of the United States|1850 Census]], though usage continued to evolve through the [[U.S. Census#Eleventh Census of the United States|1890 Census]], in which, for the first time, the Census mixed unincorporated places with incorporated places in its products with "town" as its label. This made it confusing to determine which of the "towns" were or were not incorporated. The [[United States Census, 1900|1900]] through [[U.S. Census#Fifteenth Census of the United States .281930.29|1930]] Censuses did not report data for unincorporated places. For the [[United States Census, 1940|1940 Census]], the Census Bureau compiled a separate report of unofficial, unincorporated communities of 500 or more people. The Census Bureau officially defined this category as "unincorporated places" in the [[United States Census, 1950|1950 Census]]. For the 1950 Census, these types of places were identified only outside [[urbanization|urbanized]] areas. In [[United States Census, 1960|1960]], the Census Bureau also identified unincorporated places inside urbanized areas, but with a population of at least 10,000. For the [[United States Census, 1970|1970 Census]], the population threshold for "unincorporated places" in urbanized areas was reduced to 5,000. For the [[United States Census, 1980|1980 Census]], the designation was changed to "census-designated places". For the [[United States Census, 1990|1990 Census]], the population threshold for CDPs in urbanized areas was reduced to 2,500. From [[1950]] through [[1990]], the Census Bureau specified other population requirements for unincorporated places or CDPs in [[Alaska]], [[Puerto Rico]], island areas, and [[Indian reservation|Native American reservation]]s. Minimum population criteria for CDPs were dropped with the [[United States Census, 2000|2000 Census]].<ref name="Census2010" /> The Census Bureau's Participant Statistical Areas Program (PSAP) allows designated participants to review and suggest modifications to the boundaries for CDPs.<ref>[http://www.census.gov/geo/www/psap2010/psap2010_main.html "Participant Statistical Areas Program (PSAP)"], U.S. Census Bureau, accessed [[2008-03-09]]</ref> The PSAP will be offered to county and municipal planning agencies during 2008. ==Effects of designation and examples== The boundaries of such places may be defined in cooperation with local or tribal officials, but are not fixed, and do not affect the status of local government or incorporation; the territories thus defined are strictly statistical entities. CDP boundaries may change from one census to the next to reflect changes in settlement patterns. Further, as statistical entities, the boundaries of the CDP may not correspond with local understanding of the area with the same name. Recognized communities may be divided into two or more CDPs while on the other hand, two or more communities may be combined into one CDP. A CDP may also cover the unincorporated part of a named community where the rest lies within an incorporated place. By defining an area as a CDP, that locality then appears in the same category of census data as incorporated places. This distinguishes CDPs from other census classifications, such as [[minor civil division]]s (MCDs), which are in a separate category. The [[population]] and [[demographics]] of the CDP district are included in the data of county subdivisions containing the CDP. In no case is a CDP defined within the boundaries of what the Census Bureau regards to be an incorporated city, village or borough. However, the Census Bureau considers [[New England town|Town]]s in [[New England]] states and [[New York]] as well as Townships in some other states as MCDs, even though they are [[municipal corporation|incorporated municipalities]] in those states. ==Purpose of designation== There are a number of reasons for the CDP designation: * The area may be more urban than its surroundings, having a concentration of population with a definite residential nucleus, such as [[Whitmore Lake, Michigan]], or [[Hershey, Pennsylvania]]. * A formerly incorporated place may disincorporate or be partly [[annexation|annex]]ed by a neighboring town, but the former town or a part of it may still be reported by the census as a CDP by meeting criteria for a CDP. An example is the former village of [[Covedale, Ohio]], compared with [[Covedale (CDP), Ohio]]. * The CDP designation may apply to large [[military base]]s (or parts of a military base) that are not within the boundaries of any existing community, such as [[Fort Campbell North, Kentucky|Fort Campbell North]] and [[Fort Knox, Kentucky|Fort Knox]] in [[Kentucky]]. * In some cases, a CDP may be defined for the urbanized area surrounding an incorporated municipality, but which is outside the municipal boundaries, for example [[Greater Galesburg, Michigan]] or [[Greater Upper Marlboro, Maryland]]. * In other cases, the boundary of an incorporated place may bisect a recognized community. An example of this is [[Bostonia, California]], which straddles the city limits of [[El Cajon, California|El Cajon]]. The USGS places the nucleus of Bostonia within El Cajon. The Bostonia CDP covers the greater El Cajon area in unincorporated [[San Diego County]] that is generally north of that part of Bostonia within El Cajon. * The Census Bureau treats all [[township (United States)|townships]] as unincorporated places, even in those states where townships are incorporated under state law. This is so even in those states (i.e., [[Indiana]], [[Michigan]], [[Minnesota]], [[New Jersey]] and [[South Dakota]]) where the Census Bureau acknowledges that "All townships are actively functioning governmental units." [http://www.census.gov/geo/www/GARM/Ch8GARM.pdf] * In some states, a CDP may be defined within an incorporated municipality that (for the purposes of the census) is regarded as a [[minor civil division]]. For example, towns in [[Massachusetts]] and [[Connecticut]] are incorporated municipalities, but may also include both rural and urban areas. CDPs may be defined to describe urbanized areas within such municipalities, as in the case of [[North Amherst, Massachusetts]]. Another example is [[Cumberland Head, New York]], part of [[Plattsburgh (town), New York|Plattsburgh, New York]]. * Some CDPs represent an aggregation of several nearby communities, for example [[Shorewood-Tower Hills-Harbert, Michigan]] or [[Egypt Lake-Leto, Florida]]. However, the Census Bureau has proposed to discontinue this method for the [[United States Census, 2010|2010 Census]].<ref name="Census2010">[http://www.census.gov/geo/www/psap2010/cdp.040607.b.html Census Designated Place (CDP) Program for the 2010 Census - Proposed Criteria], ''[[Federal Register]]'', [[April 6]], [[2007]] (Volume 72, Number 66), accessed [[April 12]], [[2007]].</ref> * [[Hawaii]] is the only state that has no incorporated places recognized by the U.S. Census Bureau below the county level. All data for places in Hawaii reported by the census are CDPs. *In some states, the Census Bureau may designate an entire minor civil division (MCD) as a CDP (for example [[West Bloomfield Township, Michigan]] or [[Reading, Massachusetts]]). Such designations are used in states where the MCDs function with strong governmental authority and provide services equivalent to an incorporated municipality (New England, the Middle Atlantic States, Michigan, and Wisconsin). MCDs appear in a separate category in census data from places (i.e., incorporated places and CDPs); however, such MCDs strongly resemble incorporated places, and so CDPs coterminous with the MCDs are defined so that such places appear in both categories of census data. This practice will no longer be used in the [[United States Census, 2010|2010 Census]].<ref name="Census2010"/> == See also == *[[Designated place]], a counterpart in the [[Census in Canada|Canadian census]] *[[ZIP Code Tabulation Area]] ==Notes== {{reflist}} ==References== * U.S. Census Bureau, Geography Division, "''[http://www.census.gov/geo/www/cob/pl_metadata.html#cdp Cartographic Boundary Files]''", Census-designated place.
