144-654: The 1890 Census , in which the Census mixed unincorporated places with incorporated places in its products with "town" or "village" as its label.

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
168-461: 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
192-526: 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

240-457: 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: Family (U.S. Census) A family

312-484: The boundaries for CDPs. The PSAP 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,
336-419: 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
360-518: 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
384-788: 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.

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.

456-457: 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,

The amount of soil sluiced away in this way seems incredible. Bluffs sixty to a hundred feet thick have been washed away for hundreds of acres together. But they were not rich, the gold has “stopped,” the town is dilapidated--but we had to pay big prices nevertheless. As gold mining in
