341-643: 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.

496-484: 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,
