Using the value of a dollar from 2009–2010 as a baseline, the most recent analysis by the National Center for Education Statistics found that, in the period from 1980 to 2011, college tuition (both private and public, including universities) increased on average more than 4.46% per year. Between 2000–2001 and 2010–2011, prices for undergraduate tuition, room, and board at public institutions rose 42 percent, and prices at private not-for-profit institutions rose 31 percent, after adjusting for inflation. The inflation-adjusted price for undergraduate tuition, room, and board at private for-profit institutions was 5 percent higher in 2010–2011 than in 2000–2001.
