A brief tutorial for finding, downloading, and displaying Census data in an ArcGIS thematic map is now available.
These instructions illustrate only a small portion of the information available from the U.S. Census Bureau. If you wish to work more with these data, I encourage you to experiment…
Another source for 2010 Census data is the Census Bureau’s TIGER/Line Shapefiles page. The site includes various Census geographies (e.g., blocks, block groups, tracts) as well as documentation.

Today, ESRI released additional 2010 Census data to the public. Downloading and formatting Census data can be very time-consuming, so this resource is a real boon to users of Census data.
Additional resources and articles from ESRI can be found on their news page.
