Project Description
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. Data sets for 1990 are scheduled for release in early 2007.
Project Highlights

Spatial Resolution
- Data sets for the United States and Puerto Rico are available at a resolution of 30 arc-seconds or approximately 1 kilometer.
- Data sets for 50 metropolitan statistical areas with a population of one million or more are available at a resolution of 7.5 arc-seconds or approximately 250 meters.
