Series Information File for the 2018 TIGER/Line Shapefile, Current Block Group State-based 2018 publication 2018 The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data set, or they can be combined to cover the entire nation. Block Groups (BGs) are clusters of blocks within the same census tract. Each census tract contains at least one BG, and BGs are uniquely numbered within census tracts. BGs have a valid code range of 0 through 9. BGs have the same first digit of their 4-digit census block number from the same decennial census. For example, tabulation blocks numbered 5001, 5002, 5005,.., 5999 within census tract 1210.02 are also within BG 5 within that census tract. BGs coded 0 are intended to only include water area, no land area, and they are generally in territorial seas, coastal water, and Great Lakes water areas. Block groups generally contain between 600 and 5,000 people. A BG usually covers a contiguous area but never crosses county or census tract boundaries. They may, however, cross the boundaries of other geographic entities like county subdivisions, places, urban areas, voting districts, congressional districts, and American Indian / Alaska Native / Native Hawaiian areas. The BG boundaries in this release are those that were delineated as part of the Census Bureau's Participant Statistical Areas Program (PSAP) for the 2010 Census. In order for others to use the information in the Census MAF/TIGER database in a geographic information system (GIS) or for other geographic applications, the Census Bureau releases to the public extracts of the database in the form of TIGER/Line Shapefiles. notPlanned http://tigerweb.geo.census.gov/arcgis/services/TIGERweb/tigerWMS_ACS2018/MapServer/WmsServer?REQUEST=GetMap&SERVICE=WMS&VERSION=1.3.0&LAYERS=Census Block Groups,Census Block Groups Labels&STYLES=default,default&FORMAT=image/svg+xml&BGCOLOR=0xFFFFFF&TRANSPARENT=TRUE&CRS=EPSG:4326&BBOX=42.389053,-71.907142,42.52679,-71.879999&WIDTH=891&HEIGHT=751 URL for the TigerWeb Web Mapping Service URL for the TigerWeb Web Mapping Service State or equivalent entity Polygon Block Group BG theme None U.S. United States State or Equivalent Entity place ISO 3166 Codes for the representation of names of countries and their subdivisions otherRestrictions Access Constraints: None Use Constraints:The TIGER/Line Shapefile products are not copyrighted however TIGER/Line and Census TIGER are registered trademarks of the U.S. Census Bureau.
