- Abstract
- United States Census Block Centroid Populations is a point theme representing the populations of the U.S. Census blocks for United States. U.S. Census blocks are the smallest geographic entities within a county for which the Census Bureau tabulates population.
- Purpose
- United States Census Block Centroid Populations provides population and other demographic information for each U.S. Census block centroid within United States.
- Supplemental Information
- Largest scale when displaying the data: 1:100,000. This dataset comes with an ESRI layer file representing the number of households.

- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using either tools in ArcGIS or ESRI SDC Data Development Kit Professional 2 (DDKP2). The SDC data set is then imported into a file geodatabase 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 calculated from latitude/longitude coordinates. The horizontal positional accuracy is unknown.
