Cartographic Boundary Files Descriptions and Metadata
Places, for the reporting of decennial census data, include census designated places, consolidated cities, and incorporated places.
Each place is assigned a five-digit Federal Information Processing Standards (FIPS) code in alphabetical order within each state.
Census designated places (CDPs) are delineated for each decennial census as the statistical counterparts of incorporated places. CDPs are delineated to provide data for settled concentrations of population that are identifiable by name but are not legally incorporated under the laws of the state in which they are located. The boundaries usually are defined in cooperation with local or tribal officials. These boundaries, which usually coincide with visible features or the boundary of an adjacent incorporated place or other legal entity boundary, have no legal status, nor do these places have officials elected to serve traditional municipal functions. CDP boundaries may change from one decennial census to the next with changes in the settlement pattern; a CDP with the same name as in an earlier census does not necessarily have the same boundary.
There are no population size requirements for the CDPs designated in conjunction with Census 2000. For the 1990 census and earlier censuses, the U.S. Census Bureau required CDPs to qualify on the basis of various minimum population size criteria.
Beginning with the 1950 census, the U.S. Census Bureau, in cooperation with state and local governments (and American Indian tribal officials starting with the 1990 census), identified and delineated boundaries and names for CDPs. In the data products issued in conjunction with Census 2000, the name of each such place is followed by "CDP," as was the case for the 1990 and 1980 censuses. In the data products issued in conjunction with the 1950, 1960, and 1970 censuses, these places were identified by "(U)," meaning "unincorporated place."
Hawaii is the only state that has no incorporated places recognized by the U.S. Census Bureau. All places shown in the data products for Hawaii are CDPs. By agreement with the state of Hawaii, the U.S. Census Bureau does not show data separately for the city of Honolulu, which is coextensive with Honolulu County.
There are no incorporated places in Puerto Rico; instead, the U.S. Census Bureau provides decennial census data for two types of census designated places (CDPs): (1) zonas urbanas, representing the governmental center of each municipio and (2) comunidades, representing other settlements. For Census 2000, there are no minimum population size requirements for CDPs. (For the 1990 census, the U.S. Census Bureau had required comunidades to have at least 1,000 people.)
Each CDP is assigned a five-digit Federal Information Processing Standards (FIPS) code, based on the alphabetical order of the CDP name within each state. If CDP names are duplicated within a state and they represent distinctly different areas, a separate code is assigned to each CDP name alphabetically by primary county in which each place is located.
A consolidated government is a unit of local government for which the functions of an incorporated place and its county or minor civil division (MCD) have merged. The legal aspects of this action may result in both the primary incorporated place and the county or MCD continuing to exist as legal entities, even though the county or MCD performs few or no governmental functions and has few or no elected officials. Where this occurs, and where one or more other incorporated places in the county or MCD continue to function as separate governments, even though they have been included in the consolidated government, the primary incorporated place is referred to as a "consolidated city."
The presentation of data for consolidated cities varies depending on the geographic presentation. In some hierarchical presentations, consolidated cities are not shown. These presentations include the incorporated places within the consolidated city and the "consolidated city (balance)." Although hierarchical presentations do not show the consolidated city, the data for it are the same as the county or county subdivision with which it is coextensive. Other hierarchical presentations do not show the consolidated city, county or county subdivision, and (balance) as separate entities.
For inventory geographic presentations, the consolidated city appears at the end of the listing of places. The data for the consolidated city include the data for all places that are part of and within the consolidated city. The "consolidated city (balance)" entry shows the data for the portion of the consolidated government minus the incorporated places, and is shown in alphabetical sequence with other places that comprise the consolidated city. For statistical purposes, these entities are treated as statistically equivalent to a place and have no legal basis or functions.
In summary presentations by size of place, the consolidated city is not included. The places within consolidated cities are categorized by their size, as is the "consolidated city (balance)." A few incorporated places are partially inside and partially outside a consolidated city. Data tabulations by incorporated place will include all territory within the incorporated place, while the tabulation for the incorporated place within a consolidated city is only for part of the incorporated place.
Each consolidated city is assigned a five-digit Federal Information Processing Standards (FIPS) code that is unique within state. The incorporated places and the "consolidated city (balance)" also are assigned five-digit FIPS place codes that are unique within state. The code assigned to each incorporated place within a consolidated city is the same as its regular incorporated place code; an incorporated place that is partially included in a consolidated city does not have a different code for the portions inside and outside the consolidated city. FIPS codes are assigned based on alphabetical sequence within each state.
Incorporated places recognized in decennial census data products are those reported to the U.S. Census Bureau as legally in existence on January 1, 2000, under the laws of their respective states, as cities, boroughs, towns, and villages, with the following exceptions: the towns in the New England states, New York, and Wisconsin, and the boroughs in New York are recognized as minor civil divisions for statistical purposes; the boroughs in Alaska are county equivalents for decennial census statistical presentation purposes. In four states (Maryland, Missouri, Nevada, and Virginia), there are one or more incorporated places known as "independent cities" that are primary divisions of a state and legally not part of any county. For statistical purposes, the U.S. Census Bureau may treat an independent city as a county equivalent, county subdivision, and place.
The U.S. Census Bureau treats the villages in American Samoa as incorporated places because they have their own officials, who have specific legal powers as authorized in the American Samoa Code. The village boundaries are traditional rather than being specific, legally defined locations. There are no incorporated places in Guam and the Northern Mariana Islands. The Census Bureau treats the three towns in the Virgin Islands of the United States as incorporated places.
There are a few incorporated places that do not have a legal description. An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor civil division, which generally is created to provide services or administer an area without regard, necessarily, to population.
Each incorporated place is assigned a five-digit Federal Information Processing Standards (FIPS) code, based on the alphabetical order of the incorporated place name within each state. If incorporated place names are duplicated within a state and they represent distinctly different areas, a separate code is assigned to each incorporated place name alphabetically by primary county in which each incorporated place is located, or if both incorporated places are in the same county, alphabetically by their legal description (for example, "city" before "village").
