This is a MD iMAP hosted service. Find more information at http://imap.maryland.gov. The TIGER/Line Files include both incorporated places (legal entities) and census designated places or CDPs (statistical entities). An incorporated place is established to provide governmental functions for a concentration of people as opposed to a minor civil division (MCD) - which generally is created to provide services or administer an area without regard - necessarily - to population. Places always nest within a State - but may extend across county and county subdivision boundaries. An incorporated place usually is a city - town - village - or borough - but can have other legal descriptions. CDPs are delineated for the 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 for CDPs often are defined in partnership with State - local - and/or tribal officials and usually coincide with visible features or the boundary of an adjacent incorporated place or another legal entity. CDP boundaries often change from one decennial census to the next with changes in the settlement pattern and development; a CDP with the same name as in an earlier census does not necessarily have the same boundary. The only population/housing size requirement for CDPs for the 2010 Census is that they must contain some housing and population. The boundaries of all 2010 Census incorporated places are as of January 1 - 2010 as reported through the Census Bureau's Boundary and Annexation Survey (BAS). The boundaries of all 2010 Census CDPs were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP).Feature Service Link:http://geodata.md.gov/imap/rest/services/Demographics/MD_CensusDesignatedAreas/FeatureServer/1 ADDITIONAL LICENSE TERMS: The Spatial Data and the information therein (collectively "the Data") is provided "as is" without warranty of any kind either expressed implied or statutory.
