Why is it impossible to get "exit option" or employment survey data from UofC?

Regarding law school admissions, I found out the number of applicants from UChicago in 2016: 169.

If 84% are accepted to T-14 law, that’s 142 students out of 169.

Side note: Just astonished by how far law as a profession has declined since 2008! Applicants to law schools from top undergrad institutions plummeted from 3,705 in 2010 to just 1,809 in 2017. That’s a 51.4% decline in less than a decade. Seems like the best and brightest are avoiding law schools altogether.
