We’ve recently come across these two excellent sites for state-by-state economic statistics:

• StateMaster allows you to research and compare a multitude of different data on US states, from sources including the U.S. Census Bureau, the FBI, and the National Center for Educational Statistics: http://www.statemaster.com/index.php

• State Profiles provide a quarterly summary of state banking and economic conditions: http://www.fdic.gov/bank/analytical/stateprofile/index.html
