ACensus County Division(CCD) is asubdivisionof acountyused by theUnited States Census Bureaufor the purpose of presentingstatistical data.A CCD is a relatively permanent statistical area delineated cooperatively by the Census Bureau andstateand local government authorities. CCDs are defined in 21 states that do not have well-defined and stableminor civil divisions(MCDs), such astownships,with local governmental purposes, or where the MCDs are deemed to be "unsatisfactory for the collection, presentation, and analysis of census statistics".[1][2][dead link]
CCDs are not governmental units and have no legal or governmental functions. Their boundaries usually follow visible features, such as roads, railroads, streams, power transmission lines, or mountain ridges, and coincide with the boundaries ofcensus tracts.CCDs do not span county lines. Each CCD is given a name based on the name of the largest population center in the area, a prominent geographic feature, the county name, or another well-known local name that identifies its location.[1][2][dead link]
CCDs were first implemented for tabulation of1950 Censusdata from the state ofWashington.As of the2010 census,a total of 5,191 CCDs were defined in 20 states.[2]

North Dakotabriefly adopted CCDs for the1970 Census,but soon returned to using MCDs for subsequent censuses. The main reason for abandoning CCDs was financial. As legal units of local government, MCDs could qualify forfederal revenue sharingfunds, while purely statistical areas like CCDs did not.[2]In 2008, Tennessee changed from using CCDs to using MCDs, leaving 20 states using CCDs as of the2010 census.[3]
