GIS_PLANNING.Census_Block_Groups_2000
Abstract:A census block group (BG) is a cluster of census blocks having the same first digit of their four-digit identifying numbers within a census tract. For example, block group 3 (BG 3) within a census tract includes all blocks numbered from 3000 to 3999. BGs generally contain between 600 and 3,000 people, with an optimum size of 1,500 people. Most BGs were delineated by local participants as part of the U.S. Census Bureau's Participant Statistical Areas Program. The U.S. Census Bureau delineated BGs only where a local, state, or tribal government declined to participate or where the U.S. Census Bureau could not identify a potential local or tribal participant.Data Development:N/AKey Attribute Fields:TRACT: Tract number that the block group is locatedGROUP_: Block Group NumberSTFID: State, County, Tract, and Block Group codeCoordinate System:Projection: Lambert Conformal ConicXY Coordinate System: NAD 1983 StatePlane Pennsylvania South FIPS 3702 (US Feet)Datum: NAD 1983Units of Measurement: Foot_USThematic Mapping:No particular field for thematic mapping and labelingOther Information:N/A
