28-625: CDPs have been used in each decennial census since 1980 as the counterparts of incorporated places , such as self-governing cities , towns , and villages , for the purposes of gathering and correlating statistical data. CDPs are populated areas that generally include one officially designated but currently unincorporated community, for which the CDP is named, plus surrounding inhabited countryside of varying dimensions and, occasionally, other, smaller unincorporated communities as well. CDPs include small rural communities, edge cities , colonias located along

56-442: A place as a concentration of population which has a name, is locally recognized, and is not part of any other place. A place typically has a residential nucleus and a closely spaced street pattern, and it frequently includes commercial property and other urban land uses. A place may be an incorporated place (a self-governing city , town , or village ) or it may be a census-designated place (CDP). Incorporated places are defined by

84-420: A CDP have no legal status and may not always correspond with the local understanding of the area or community with the same name. However, criteria established for the 2010 census require that a CDP name "be one that is recognized and used in daily communication by the residents of the community" (not "a name developed solely for planning or other purposes") and recommend that a CDP's boundaries be mapped based on

112-760: A city, town (except in the New England states, New York , and Wisconsin ), borough (except in Alaska and New York), or village, and having legally prescribed limits, powers, and functions. Requirements for incorporation vary widely among the states; some states have few specific criteria, while others have established population thresholds and occasionally other conditions (for example, minimum land area, population density , and distance from other existing incorporated places) that must be met for incorporation. The Census Bureau recognizes incorporated places in all U.S. states except Hawaii ; for Hawaii, by agreement with

140-503: A population of at least 10,000. For the 1970 Census , the population threshold for "unincorporated places" in urbanized areas was reduced to 5,000. For the 1980 Census , the designation was changed to "census designated places" and the designation was made available for places inside urbanized areas in New England. For the 1990 Census , the population threshold for CDPs in urbanized areas was reduced to 2,500. From 1950 through 1990,

168-708: Is available from the Integrated Public Use Microdata Series . It was the first census to designate " Native Hawaiian and Other Pacific Islander " as a racial group separate from Asians . The census was also the first census to be directed by a woman, Barbara Everitt Bryant . To increase black participation in the 1990 United States census, the bureau recruited Bill Cosby , Magic Johnson , Alfre Woodard , and Miss America Debbye Turner as spokespeople. The Integrated Public Use Microdata Series . Aggregate data for small areas, together with electronic boundary files, can be downloaded from

196-485: Is the only state that uses all four terms for types of incorporated places. Only two other states ( Connecticut and Pennsylvania ) include "boroughs" as incorporated places. Eleven U.S. states have only "cities", and the remainder of the states have various combinations of "cities", "towns", and "villages". Not all entities designated as "towns" and "boroughs" are considered by the Census Bureau to be places. In

224-587: The 1890 Census , in which the Census mixed unincorporated places with incorporated places in its products with "town" or "village" as its label. This made it confusing to determine which of the "towns" were or were not incorporated. The 1900 through 1930 Censuses did not report data for unincorporated places. For the 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

252-400: The 1950 Census and used that term through the 1970 Census. For the 1950 Census, these types of places were identified only outside " urbanized areas ". In 1960 , the Census Bureau also identified unincorporated places inside urbanized areas (except in New England , whose political geography is based on the New England town , and is distinctly different from other areas of the U.S.), but with

280-530: The Census Bureau , determined the resident population of the United States to be 248,709,873, an increase of 9.8 percent over the 226,545,805 persons enumerated during the 1980 census . Approximately 16 percent of households received a "long form" of the 1990 census, which contained more than 100 questions. Full documentation on the 1990 census, including census forms and a procedural history,

308-525: The Mexico–United States border , and unincorporated resort and retirement communities and their environs. The boundaries of any CDP may change from decade to decade, and the Census Bureau may de-establish a CDP after a period of study, then re-establish it some decades later. Most unincorporated areas within the United States are not and have not been included in any CDP. The boundaries of

336-539: The National Historical Geographic Information System . Personally identifiable information will be available in 2062. This was the first census since 1880 in which Chicago was not the second-largest city, having been overtaken by Los Angeles . As of the 2020 census , Los Angeles has remained the nation's second-largest city. The results of the 1990 census determined the number of seats that each state receives in

364-441: The Census Bureau considers some towns in New England states, New Jersey and New York as well as townships in some other states as MCDs, even though they are incorporated municipalities in those states. In such states, CDPs may be defined within such towns or spanning the boundaries of multiple towns. There are a number of reasons for the CDP designation: Incorporated place The United States Census Bureau defines

392-414: The Census Bureau specified other population requirements for unincorporated places or CDPs in Alaska , Puerto Rico , island areas, and Native American reservations . Minimum population criteria for CDPs were dropped with the 2000 Census . The Census Bureau's Participant Statistical Areas Program (PSAP) allows designated participants to review and suggest modifications to the boundaries for CDPs. The PSAP

420-643: The Census Bureau. The boundaries of a CDP have no legal status and may not correspond with the 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. Although only about one-fifth as numerous as incorporated places (in 1990, of 23,435 "places", 19,289 were incorporated municipalities, and 4,146 were not incorporated municipalities), CDPs are important geographic units. The CDP permits

448-885: The Office of the Governor, the Census Bureau recognizes all places as census-designated places (CDPs) rather than as incorporated places. Puerto Rico and several of the outlying areas under United States jurisdiction (such as Guam and the Northern Mariana Islands ) also have no incorporated places. Different states use a variety of terms for their incorporated places. The designations "city", "town", "village", and "borough" are most frequent, but one or more places in Kentucky , Montana , Nevada , and Tennessee have place-type governments (usually consolidated ones) that do not have any of these designations. New Jersey

476-522: The United States resided in CDPs. Statistics Canada uses the term designated place (DPL) for unincorporated population centers. However, the criteria for delineating a DPL are different from that for a CDP. The Census Bureau lists a location (latitude and longitude) for each place, although this list is not intended for general use and is part of the Bureau's TIGER mapping system to graphically represent

504-419: 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

532-786: The geographic extent associated with inhabitants' regular use of the named place. There is no provision, however, that this name recognition be unanimous for all residents, or that all residents use the community for which the CDP is named for services provided therein. There is no mandatory correlation between CDP names or boundaries and those established for other human purposes, such as post office names or zones, political precincts, or school districts. The Census Bureau states that census-designated places are not considered incorporated places and that it includes only census-designated places in its city population list for Hawaii because that state has no incorporated cities. In addition, census city lists from 2007 included Arlington County, Virginia 's CDP in

560-448: The laws of the states in which they are contained. The Census Bureau delineates CDPs. A small settlement in the open countryside or the densely settled fringe of a large city may not be a place as defined by the Census Bureau. As of the 1990 census, 26% of the people in the United States lived outside of places. An incorporated place, under the Census Bureau's definition, is a type of governmental unit incorporated under state law as

588-555: The list with the incorporated places, but since 2010, only the Urban Honolulu CDP, Hawaii, representing the historic core of Honolulu, Hawaii , is shown in the city and town estimates. The Census Bureau reported data for some unincorporated places as early as the first census in 1790 (for example, Louisville, Kentucky , which was not legally incorporated in Kentucky until 1828), though usage continued to develop through

616-455: The same category of census data as incorporated places. This distinguishes CDPs from other census classifications, such as minor civil divisions (MCDs), which are in a separate category. The population and demographics of the CDP are included in the data of county subdivisions containing the CDP. Generally, a CDP shall not be defined within the boundaries of what the Census Bureau regards to be an incorporated city, village or borough. However,

644-557: The same place and may even be outside the area that local residents think of as that community. The Census Bureau's location of a place is the approximate geographic center of the polygon making up the boundaries of the place at the time of the decennial census. The USGS location of a populated place is the center of the original place, if known, such as the city or town hall, main post office, town square or main intersection regardless of changes over time. 1990 United States Census The 1990 United States census , conducted by

672-459: The six New England states, and in New York and Wisconsin, the term "town" refers to what the Census Bureau classifies as a minor civil division (MCD) rather than a place. The MCDs in these states, while often functioning with all the powers of city governments, can contain considerable rural area; outside of New England, other units of government perform the incorporated place function. In Alaska,

700-511: The statistical areas used in census data. The Census Bureau's criteria for establishing the location does not correspond to the criteria used by the United States Geological Survey (USGS) for locating named communities, which is intended to be an authoritative reference for a place's location. The central location of a place shown on Census Bureau maps for a community may differ significantly from that on USGS maps for

728-436: The tabulation of population counts for many localities that otherwise would have no identity within the Census Bureau's framework of geographic areas. 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 divisions (MCDs), which are in a separate category. In 1990, over 29 million people in

756-644: The term "borough" refers to territory governed as a county rather than as a place; in New York, the Census Bureau treats the five boroughs that make up New York City as MCDs. Census-designated places (CDPs) are communities that lack separate municipal governments, and for statistical purposes are defined by the Census Bureau in order to statistically combine and compare populated areas that physically resemble incorporated places. Before each decennial census, CDPs are delineated by state and local agencies, and by tribal officials according to Census Bureau criteria. The resulting CDP delineations are then reviewed and approved by

784-447: Was to be offered to county and municipal planning agencies during 2008. 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,
