From the Rockinst.org:
For the second quarter in a row, tax revenues collected by states across the U.S. plummeted sharply in April-June 2009, according to the latest quarterly report on state revenue collections issued today by the Rockefeller Institute of Government.
When compared to the same period one year earlier, second-quarter 2009 tax revenues in the 50 states dropped a record 16.6 percent — the second consecutive quarter in which revenues fell more sharply than during any previous time on record. Forty-nine states saw total tax revenue fall during the quarter, with 36 states reporting double-digit declines.
