UMass is a different situation because they are largely the public system for Massachusetts so a loss in numbers for them is purely a loss of numbers.
For Ohio the percentage of funding each school receives is based on in-state Full Time Equivalents (FTEs) so the relative FTE enrollment to what the other state universities are taking in is more important. OU then could move to a freshman class of 3,000 but if everyone else is taking in 1,500 they gain a relatively larger portion of the budget. The marginal state universities and community colleges are the most at risk.
Hocking College dropped from 5,908 students to 2,305 from 2011 to 2021.
