Has nearly 19k students according to https://www.univstats.com/colleges/university-of-chicago/stu... So that's about $700/person. Less if graduated students get comped too.
No grad students. No international students. Only students who received some financial aid, but less than the total cost of attendance.
On the other hand, it goes all the way back to students from 2003.
