Census data is provided both by the U.S. Census Bureau and by the Pennsylvania State Data Center, which is a Census Bureau affiliate—as is SEDA-COG.
At present the links are divided into two groups: Current Census data and Archived Census Data. As more and more Census 2010 data is released, the links to earlier data will be moved to the Archived Census Data group and replaced with the newer 2010 data.
For up-to-date releases of Pennsylvania Census 2010 Data visit the Pennsylvania State Data Center's Census 2010 webpage.
