History

The Census Bureau reported data for some unincorporated places as early as the 1850 Census, though usage continued to develop through the 1890 Census, in which, for the first time, 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 Census Bureau's Participant Statistical Areas Program (PSAP) allows designated participants to review and suggest modifications to the boundaries for CDPs. The PSAP was to 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

 in those states. Thus, CDPs may be defined within New England towns or spanning the boundaries of multiple towns.

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

    ). 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 2010 Census.
