If you consider the number of high number of Asians and ORM mixed race students that attend Michigan , far out of proportion to their numbers in Michigan and the midwest, and the relatively low number of blacks and URM mixed race kids, I think that there is strong evidence that Michigan does not consider race. In fact, of you look at the number of Asians at Cal vs. Michigan when compared to their age-banded state population, Michigan admits an even larger proportion of Asians than Cal.
None of this is definitive since we do not have access to the admission offices data, but these are strong indicators that race is not considered in any way beyond a few special cases.
Michigan’s URM efforts mostly involve a) getting more URM applicants through outreach and b) preparing small numbers of minority HS students through new programs to give them a semester or more of transition, soft skills and catch-up so they succeed at Michigan. None of those indicate that they are using race for admission criteria.
