^ Michigan’s OOS students skew affluent mainly because the university doesn’t meet full need for OOS students. OOS admissions is highly selective, so most OOS admits have choices among multiple high-quality schools, including, usually, some schools that can make more attractive FA offers to students with demonstrated need… As a result, most of the OOS students are full-pays. Michigan does meet full need for in-state students, and about 70% of the in-state students receive FA. The situation is changing pretty rapidly for OOS students, however, as Michigan nears completion of its current $4 billion capital campaign (largest ever for a public university), one of the principal aims of which is to increase need-based FA for OOS students, with the ultimate goal to meet full need for all. They’re not there yet; I believe in the current admissions cycle they’re promising to meet full need for OOS students with family incomes up to $70K. But even that should start to move the needle pretty dramatically in the socioeconomic composition of the OOS students (who now constitute nearly half of the undergraduate student body), especially if that policy holds or is improved over several admissions cycles…
