This report provides college student tuition charges and fees for the 1999-2000 academic year at public four-year institutions, as well as comparative data for the 1998-99 academic year. The report notes that this year marked the smallest percentage tuition and fee increases in over a decade, with the average cost to undergraduate resident students rising 3.3 percent over the previous year. Increases in room and board continued to moderate, and the 4.1 percent overall rise matched that of 1998-99. The cost of attending college as a percentage of family income has stabilized over the past five years, but it has risen considerably for low-income families; for this group, these expenses represent more than 60 percent of annual income. Finally, total financial aid to students rose 4.5 percent, to a record $64.1 billion in 1998-99. The report also analyzes implications of state policy developments, as well as developments in federal, state, and institutional student financial aid. Appended are tables of selected undergraduate charges at American Association of State Colleges and Universities and National Association of State Universities and Land-Grant Colleges institutions.
