Notes: Years are in state fiscal years. Tuition data are for 4-year public institutions. Because enrollment data is only available through the 2013 school year, enrollment for the 2013-14 school year is estimated using data from past years. Illinois funding data is provided by the Fiscal Policy Center at Voices for Illinois Children.
