A Census County Division (CCD) is a subdivision of a county used by the United States Census Bureau for the purpose of presenting statistical data. 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".
