Census County Divisions September 2024 .. Census Ccunty Divisions (CCDs) are geographic areas defined by the Census Bureau. CCDs are the primary divisions of counties and their equivalent entities for the reporting of decennial census data and other programs. CCDs include census county divisions, minor civil divisions, towns in six New England states and other types of areas. The TIGER/Line shapefiles contain a 10-character geocode field for county subdivisions .. more below CCDs are important for many reasons • CCDs are an important geographic analytical area in many states. • CCDs are the equivalent of Minor Civil Divisions in 23 states. • CCDs are the equivalent of Towns in 6 New Engaland states. • extensive annual demographic data are developed for all CCDs as a part of the Amernican Community Survey 5-year estimates. • the Census Bureau develops annual model-based population estimates for CCDs that are MCDS.

CCDs as Legal Entities Minor Civil Divisions (MCDs) are the primary governmental or administrative divisions of a county in many states. MCDs represent many different kinds of legal entities with a wide variety of governmental and/or administrative functions. MCDs include areas variously designated as American Indian reservations, assessment districts, barrios, barrios-pueblo, boroughs, census subdistricts, charter townships, commissioner districts, counties, election districts, election precincts, gores, grants, locations, magisterial districts, parish governing authority districts, plantations, precincts, purchases, supervisor's districts, towns, and townships. The Census Bureau recognizes MCDs in 29 states, Puerto Rico, and the Island areas. The District of Columbia has no primary divisions, and the incorporated place of Washington is treated as an equivalent to an MCD for statistical purposes (it is also considered a state equivalent and a county equivalent).
In 23 states and the District of Columbia, all or some incorporated places are not part of any MCD. These places also serve as primary legal subdivisions and have a unique FIPS MCD code that is the same as the FIPS place code. The ANSI codes also match for those entities. In other states, incorporated places are part of the MCDs in which they are located, or the pattern is mixed—some incorporated places are independent of MCDs and others are included within one or more MCDs.
The MCDs in 12 states (Connecticut, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, Vermont, and Wisconsin) also serve as generalpurpose local governments that generally can perform the same governmental functions as incorporated places. The Census Bureau presents data for these MCDs in all data products for which place data are provided.
In New York and Maine, American Indian reservations (AIRs) exist outside the jurisdiction of any town (MCD) and thus also serve as the equivalent of MCDs for purposes of data presentation. CCDs as Statistical Entities Census County Divisions (CCDs) are areas delineated by the Census Bureau in cooperation with state officials and local officials for statistical purposes. CCDs are not governmental units and have no legal functions. CCD boundaries usually follow visible features and, in most cases, coincide with census tract boundaries. The name of each CCD is based on a place, county, or well-known local name that identifies its location. CCDs exist where:
CCDs have been established for the following 20 states: Alabama, Arizona, California, Colorado, Delaware, Florida, Georgia, Hawaii, Idaho, Kentucky, Montana, Nevada, New Mexico, Oklahoma, Oregon, South Carolina, Texas, Utah, Washington, WyomingCensus Subareas are statistical subdivisions of boroughs, city and boroughs, municipalities, and census areas, the latter of which are the statistical equivalent entities for counties in Alaska. The state of Alaska and the Census Bureau cooperatively delineate the census subareas to serve as the statistical equivalents of MCDs. Unorganized Territories (UTs) have been defined by the Census Bureau in 9 minor civil division (MCD) states and American Samoa where portions of counties or equivalent entities are not included in any legally established MCD or incorporated place. The Census Bureau recognizes such separate pieces of territory as one or more separate county subdivisions for census purposes. It assigns each unorganized territory a descriptive name, followed by the designation “unorganized territory” and county subdivision FIPS and ANSI codes. Unorganized territories are recognized in the following states and equivalent areas: Arkansas, Indiana, Iowa, Maine, Minnesota, New York, North Carolina, North Dakota, South Dakota Undefined county Subdivisions—In water bodies, primarily Great Lakes waters and territorial sea, legal county subdivisions do not extend to cover the entire county. For these areas, the Census Bureau created a county subdivision with a FIPS code of 00000 and ANSI code of 00000000 named "county subdivision not defined." The following states and equivalent areas have these county subdivisions: Connecticut, Illinois, Indiana, Maine, Massachusetts, Michigan, Minnesota, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Wisconsin, Puerto Rico Using the CCD Shapefiles Download TL California CouSub shapefile County Subdivision State-based Shapefile Record Layout
