Census County Division (CCD) Program for Census 2000Final Criteria

Census county divisions (CCDs) are geographic statistical entities established cooperatively by the Census Bureau and officials of state and local governments in 21 states where minor civil divisions (MCDs) either do not exist or are unsatisfactory for reporting decennial census data. The primary goal of the CCD program is to establish and maintain a set of subcounty units that have stable boundaries and recognizable names. A CCD usually represents one or more communities, trading centers, or, in some instances, major land uses. It usually consists of a single geographic piece that is relatively compact in shape. The geographic ``building blocks'' of CCDs are census tracts, and many CCDs are groupings of several contiguous census tracts. Since the 1950s, the Census Bureau has worked with state and local officials to create subcounty areas for the collection, presentation, and analysis of census statistics in states where MCDs do not exist, are not well-known locally, or are subject to frequent change. By 1990, 21 states had shifted to CCDs: Alabama, Arizona, California, Colorado, Delaware, Florida, Georgia, Hawaii, Idaho, Kentucky, Montana, Nevada, New Mexico, Oklahoma, Oregon, Sou
