From the abstract:
Federal taxpayers choose between itemizing deductions and claiming the standard deduction. Itemizers can claim deductions for state and local income and property taxes paid. (Through 2013, taxpayers may deduct state and local sales taxes paid in lieu of income taxes.) In 2011, 46.6 million taxpayers claimed the deduction for state and local taxes paid, deducting almost $470 billion from their tax returns.
