Census Block Demographics

Census Blocks are the smallest geographic area for which the Census Bureau develops polygon shapefiles and tabulates demographic data.  Census blocks are defined for each decennial census and may be updated as to block geocode and geographic extent from census to census.  In general, demographic data are tabulated at the census block level only from the decennial census.  There are more than 8 million Census  2020 census blocks covering the U.S. wall-to-wall.  This section is focused on Census 2020 census blocks using iVDA.

 

iVDA is one part of a broader VDA GIS resource framework.  See more about VDA GIS.
