You're not wrong. The assumption was that UCB is broadly representative. Looking at the full system data: https://www.universityofcalifornia.edu/infocenter/fall

You're not wrong. The assumption was that UCB is broadly representative. Looking at the full system data: https://www.universityofcalifornia.edu/infocenter/fall-enrollment-glance https://www.universityofcalifornia.edu/infocenter/fall-enrol... Given my own knowledge of the UC system, berkeley seems the most international, which is why I thought simply citing berkeley would be enough. But, point taken. Let's look into the system data. The total UC enrollment is 286271. Of this, there are 40219 Non-resident international students, which means there are 14% international students in the UC system as a whole. Thus, my using just berkeley actually shifted the data in my opponent's favor, since -- as I hypothesized -- Berkeley does indeed have more international students as a percentage of enrollment.
