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.

The American Community Survey (ACS) is a nationwide - continuous survey designed to provide communities with reliable and timely demographic - housing - social and economic data. The ACS replaces the decennial census long form in 2010 and every year thereafter. The annual ACS sample is smaller than that of previous long form surveys resulting in a larger sampling error. Coefficients of Variation (CVs) - which are statistical measures that show the relative amount of sampling error associated with an estimate - are presented here as a measure of reliability and usability of the data. The unit of geography used for the 2010 - 2014 data is the census tract - a small statistical area within a county - which is delineated every 10 years prior to the decennial census.Feature Service Link:http://geodata.md.gov/imap/rest/services/Demographics/MD_AmericanCommunitySurvey/FeatureServer/0 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.

The intent of this dataset is for it to be used to produce maps and provide a spatial reference for all Tier II segments located in Maryland. The Clean Water Act requires that States review their water quality standards every three years and revise the standards as necessary. During this required Triennial Review the State reviewed the antidegradation policy - and identified additional stream segments that meet the minimum requirements. Current Tier II designations are made based on biological characteristics from Maryland Biological Stream Survey (MBSS) data - which is collected annually. MBSS data which identifies new Tier II segments in between Triennial Review cycles are maintained on the pending list - as they are awaiting formal promulgation. The publicly maintained list of all Tier II waters can be found for each county at the following website: http://mde.maryland.gov/programs/Water/TMDL/Integrated303dReports/Pages/Antidegradation.aspx. This dataset is intended to be used in conjunction with the other official Tier II MDE datasets: Tier II Stream Catchments - Tier II MBSS Stations - and Tier II Stream Endpoints.
