<p>The other factor in the calculation is the % of oos students enrolled. As Michigan gives little to UMich, not only they ask for 3 times higher tuition for oos, they accept a lot more oos students (~40%) to make up the difference. Nevertheless, UMich also makes it easier for kids going to high school in Michigan. You only need to attend the 3 years of high school in Michigan to be eligible for in state tuition even without state residency. MSU may have even less stringent rule and my neighbor is eligible for in state tuition there but not UMich.</p>
