- Abstract
- United States Census Block Groups is a polygon theme representing the Census block groups of the United States. Attribute information includes a variety of demographic variables from the 2000 U.S. Census. This dataset is a part of the 2008 ESRI Data Maps collection.
- Purpose
- United States Census Block Groups provides boundaries and demographic information for the U.S. Census block groups within United States. The boundaries are consistent with the tract, county, and state data sets.

- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using either ESRI SDC Data Development Kit Professional 2 (DDKP2) or tools in ArcGIS. The SDC data set is then loaded into ArcSDE to verify and validate the geometry.
- Completeness Report
- After processing, the data set is checked for drawing display and number of records and file sizes compared with source materials.
- Horizontal Positional Accuracy Report
- The geospatial part of this data set was extracted from the 2000 Census TIGER/Line files. The positional accuracy of the TIGER/Line coordinates varies with the source materials used but at best meets the established National Map Accuracy standards (+/- 167 feet approximately) where 1:100,000-scale maps from the USGS are the source. The Census Bureau cannot specify the accuracy of feature updates added by its field staff or of features derived from the GBF/DIME-Files or other map sources. Thus, the level of positional accuracy in the TIGER/Line files is not suitable for high-precision measurement applications such as engineering problems, property transfers, or other uses that might require highly accurate measurements of the earth's surface.

- Entity Type Definition
- The polygons and regions represent Census block groups within United States. A block group is a combination of census blocks that is a subdivision of a census tract. A block group consists of all blocks whose numbers begin with the same digit in a given census tract. The block group is the lowest level of geography for which the Census Bureau has tabulated sample data in the 2000 census.
