Not the average class size: faculty also teach graduate students and do research, and large lectures can sit alongside small seminars.

This counts class sections, not students: a lecture of 300 is one section, so a student is more likely to sit in a large class than the share of sections suggests. Labs and discussion sections are counted separately and left out here.

9-month equated, all ranks combined. Pay tracks local cost of living as much as a college's generosity.
Spending and endowment
Fiscal 2023–24. Compared only against other public colleges: public and private colleges report finances on different accounting forms that aren't comparable. Many public universities' endowments sit mostly in a separate foundation this survey doesn't count, so this likely understates what's actually available.
