Abstract:
U.S. Census Block Centroid Populations represents the populations of the U.S. Census blocks as centroids for the United States. 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.

Process_Description:
The following steps were performed by Esri: Created the block centroids from the 2010 Census Redistricting Data (Public Law 94-171) Summary File. Reordered and renamed the fields. Added fields STATE_FIPS, CNTY_FIPS, STCOFIPS, TRACT, and BLOCK and created their values from parsing the values of the FIPS field. Projected the data set to World Geodetic System of 1984 (WGS 1984). Converted the data set to SDC. Created ArcGIS® layer file (.lyr), projection file (.prj), and spatial indices.

Detailed_Description:
Entity_Type:
Entity_Type_Label: blockpop
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.
