My daughter is applying, class of 2024. We’re out of state. Why the low % of out of state, 3-4%.
Probably because the $65K OOS price tag, with no merit or need-based aid available, is an effective deterrent.
The UCSC undergrad population also includes 8% international students, FWIW.
Probably because the UCs don’t offer any financial aid to OOS students. The ones who attend are very likely full pay.
Besides costs, another factor may be the name recognition. UCSC does not the name recognition like UCB or UCLA.
