@billcsho its very difficult to compare pre and post common app statistics for UMich as well as pre and post 2010 figures. Asians make up a tiny proportion of Michigan’s population - by the ACT report about 2% for 2105. UMich had a 14% Asian freshman class. In 2006 it was 10.7%. In addition there is the ‘2 or more races/other’ category which are primarily White-Asian and White-Black non hispanic kids (about 3% of 2015 class) . In the old days this category did not exist.
The percentage of Asian kids has risen significantly, and even more if you include the some of the multi-racial kids.
UMich does not give a breakdown by in and out of state. More black kids will attend UM with the replacement of DPS with charters, and I expect the percentages to rise slowly over the next decade because of better K-12s.
