census

2010 total population counts per county in the United States from the 2010 decennial census.

The U.S. Census Grids provide raster data sets that include not only population and housing counts, but a wide variety of socioeconomic characteristics. These gridded data sets transform irregularly shaped census block and block group boundaries into a regular surface – a raster grid – for faster and easier analysis. Data sets are currently available for the year 2000.
