Journalists and others who need information quickly to report breaking news, for example, fared worse last year. The rate at which the government granted so-called expedited processing, which moves an urgent request to the front of the line for a speedy answer, fell from 24 percent in 2011 to 17 percent last year. The CIA denied every such request last year.

Under increased budget pressure across the government, agencies more often insisted that people pay search and copying fees. It waived costs in 59 percent of requests, generally when the amount was negligible or the release of the information is in the public interest, a decline from 64 percent of cases a year earlier. At the Treasury Department, which faced questions about its role in auto bailouts and stimulus programs during Obama's first term, only one in five requests were processed at no charge. A year earlier, it granted more than 75 percent of fee waivers. The CIA denied every request last year to waive fees.

The 33 agencies that AP examined were: Agency for International Development, CIA, Agriculture Department, Commerce Department, Consumer Product Safety Commission, Defense Department, Education Department, Energy Department, Department of Health and Human Services, Department of Homeland Security, Department of Housing and Urban Development, Interior Department, Justice Department, Labor Department, State Department, Transportation Department, Treasury Department, Department of Veterans Affairs, Environmental Protection Agency, Federal Communications Commission, Federal Deposit Insurance Corporation, Federal Election Commission, Federal Trade Commission, NASA, National Science Foundation, National Transportation Safety Board, Nuclear Regulatory Commission, Office of Management and Budget, Office of the Director of National Intelligence, Securities and Exchange Commission, Small Business Administration, the Social Security Administration and the U.S. Postal Service.

Four agencies that were included in AP's previous analysis of FOIA performance did not publicly release their 2012 reports. They included the Office of National Drug Control Policy, the Office of Science and Technology Policy, the Council on Environmental Quality and the Office of Personnel Management.
