This report attempts to provide a comprehensive picture of total federal financial support for education since fiscal year (FY) 1980, the year the U.S. Department of Education was created. Programs residing in other federal agencies are included in order to account fully for all federal education expenditures. Federal support for education, excluding estimated federal tax expenditures, was an estimated $115.6 billion in FY99, an increase of 84% since FY90. After adjustment for inflation, federal support for education increased 47% between FY90 and FY99. On-budget federal funds for education programs were estimated at $82.8 billion in FY99. Off-budget support and nonfederal funds generated by federal legislation were estimated at $32.8 billion, an increase of 193% in current dollars between FY90 and FY99 and 134% in constant dollars. Over 58% of federal education support, excluding estimated federal tax expenditures, went to educational institutions in FY99. Another 20% was used for student support. The remaining 22% went to banks and other lending agencies, libraries, museums, and federal institutions. Schools and colleges derive 11% of their FY99 revenues from the federal government, with the remaining revenues coming from state and local governments. The estimated federal share of expenditures of educational institutions declined from 14% in FY80 to 10% in FY90 and up to 11% in FY99. Seven appendixes contain detailed tables of financial information. (Contains 16 tables and 3 figures.) (SLD)
