Census county division

A CCD is a relatively permanent statistical area delineated cooperatively by the Census Bureau and state and local government authorities.

CCDs are defined in 21 states that do not have well-defined and stable minor civil divisions (MCDs), such as townships, with local governmental purposes, or where the MCDs are deemed to be "unsatisfactory for the collection, presentation, and analysis of census statistics".

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 of 1950 census data from the state of Washington.

As legal units of local government, MCDs could qualify for federal revenue sharing funds, while purely statistical areas like CCDs did not.
