Michigan's public colleges and universities have become steadily less affordable over the past two decades, mirroring a national trend where state funding of public higher education has not kept pace with costs, leading to increased tuition and fees. States continually assess their higher education tuition and other policies in comparison to their closest economic competitors: neighboring states that may attract talent or regional economic investments fueled by higher education systems outpacing their own. In some extreme cases, states even create financial disincentives for college graduates to leave the state through higher education policy. In a previous report, "Michigan's College Affordability Crisis," the authors examined the affordability of Michigan's colleges and universities across institutions, across demographics and income levels, and across time. In this report, they review the affordability of Michigan's public colleges and universities relative to five neighboring states--Illinois, Indiana, Minnesota, Ohio, and Wisconsin--to see where the state may be falling down on its commitment to keeping public higher education affordable in comparison to the region.
