CDP stands for census-designated place. A CDP is an area identified by the U.S. Census Bureau for statistical purposes. CDPs are delineated for each decennial census as the statistical counterparts of incorporated places such as cities, towns, and villages.
CDPs are communities that lack separate municipal government, but which otherwise physically resemble incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name but are not legally incorporated under the laws of the state in which they are located. The boundaries of a CDP have no legal status.
Hawaii is the only state that has no incorporated places recognized by the U.S. Census Bureau. The City and County of Honolulu is reported as Honolulu CDP and the balance of Honolulu.
Honolulu CDP consists of Honolulu District, comprising the area between Red Hill and Makapuu Point, south and southwest of the crest of the Koolau Mountains and the Northwestern Hawaiian Islands. Honolulu and Arlington are the only CDPs for which
postcensal population estimates are calculated by the U.S. Census Bureau.

than other parts of Honolulu due to residential constructions outside of the Honolulu CDP.
