My wife forwarded me one of the periodic update emails she gets from campus administration peeps. The main talking point of this particular email was the size of the incoming freshman class and campus overall.
Estimated 29,300 undergrads (and ~8000 grad and prof. students!) for Fall 2016. Holy crap.
Just for kicks, I went back through the enrollment data on UCD's website. Total enrollment my freshman year (1991) was ~20k; about 17k UG and 3k grad.
