From the summary:
Trends in College Pricing provides information on changes over time in undergraduate tuition and fees, room and board, and other estimated expenses related to attending colleges and universities. The report, which includes data through 2011-12 from the College Board’s Annual Survey of Colleges, reveals the wide variation in prices charged by institutions of different types and in different parts of the country. Of particular importance is the focus on the net prices students actually pay after taking grant aid into consideration. Because of the important role of grant aid, these net prices have not followed the same sharp upward path as the published prices. Data on institutional revenues and expenditures and on changing enrollment patterns over time supplement the data on prices to provide a clearer picture of the circumstances of students and the institutions in which they study.
From the highlights:
Increases in college prices for the 2011-12 academic year reflect the influence of a weak economy and state funding that has not kept up with the growth in college enrollments. For the fifth consecutive year, the percentage increase in average tuition and fees at public four-year institutions was higher than the percentage increase at private nonprofit institutions. Substantial variation across states in pricing patterns makes national averages particularly difficult to interpret this year.
