According to a recent Nelson A. Rockefeller Institute of Government report, revenues from the combination of lotteries, pari-mutuel betting, casinos and racinos grew 2 percent in 2010 over 2009. This could be in part because ten states adopted laws to capture expanded state revenues by expanding gambling or enhancing tax receipts on gambling activities since the start of the 2008 economic recession. Total gambling revenues to state revenue coffers (excluding receipts from casinos operated by Native American tribes, which were not part of the report) were $24 billion in 2010.
The Rockefeller report, “In the Black,” provides evidence that gambling revenues are neither a large overall source of revenue for states nor a growing source of revenue over time. On average across all 50 states, gambling revenue represented just 2.4 percent of own-source general revenue in fiscal 2009.
