- Abstract
- United States Census Block Centroid Populations is a point theme representing the populations of the 2010 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.. U.S. Census blocks nest within all other tabulated census geographic entities and are the basis for all tabulated data.
- Purpose
- U.S. Census Block Centroid Populations provides population and other demographic information for each U.S. Census block centroid within the United States.
- Supplemental Information
- Largest scale when displaying the data: 1:100,000.

- Data Quality Information
- Logical Consistency Report
- The shapefile is converted to SDC (Smart Data Compression) format using tools in ArcGIS. The SDC data set is then imported into a file geodatabase to verify, validate, and if needed repair 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 and longitude coordinates. The horizontal positional accuracy is unknown.

- Entity Type Definition
- The points represent the centroids of census blocks, the smallest entity for which the Census Bureau collects and tabulates decennial census information within the United States; bounded by visible features such as streets, streams, and railroad tracks, and by nonvisible boundaries such as selected property lines and city, township, school district, and county limits. Note: this data set doesn't include the centroids of census blocks that for example consist of water polygons, medians, access ramps, and land enclosures.
