USA: State, County and Congressional District boundaries

These tables offer boundaries obtained from the U.S. Census Bureau and imported by the Fusion Tables team. They are public and can be used freely. They will be particularly useful when creating custom intensity maps.

Please report any problems with these files to googletables-feedback@google.com. You may also use Fusion Tables' commenting feature to leave us a note identifying the specific location of the issue within the table.
