Between 2013-14 and 2014-15, average published tuition and fee prices increased by 2.9% for in-state students in the public four-year sector, by 3.3% for out-of-state students in the public four-year sector and for in-district students at public two-year colleges, and by 3.7% at private nonprofit four-year institutions. These increases are higher than the 2.0% increase in the Consumer Price Index between July 2013 and July 2014, but in all sectors these price increases are lower than the average annual increases in the past five years, the past 10 years, and the past 30 years. This document reports on the prices charged by colleges and universities in 2014-15, how prices have changed over time, and how they vary within and across types of institutions, states, and regions. Also included is information on the estimated net prices students and families pay after taking financial aid into consideration. 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.
