Both the published tuition and fee prices of colleges and universities and the net prices students pay after subtracting grant aid and tax credits and deductions continued to rise between 2016-17 and 2017-18, even after adjusting for inflation. Average net prices in 2017-18 remain lower at public two-year and private nonprofit four-year institutions than they were in 2007-08 (in 2017 dollars). But each year since 2011-12, net prices have risen in these sectors, as well as at public four-year institutions, as the growth in grant aid slowed relative to the growth in tuition and fees. "Trends in College Pricing 2017" reports on the prices charged by colleges and universities in 2017-18, how prices have changed over time, and how they vary within and across types of institutions and states. It also includes estimates of the net prices students and families pay after taking financial aid into consideration, both on average and across income levels. 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.
