@preppedparent Well, the full menu of UCs are a pretty much a single click once you do the first one, so that for sure is easier.
I’d guess the reasons are:
Rise in importance of Rankings. Since USNews, in particular, splits rankings by National U and LAC, the “big college” ranking is the one most kids/parents look at. And internationally the WSJ/Times International rankings reward the top publics’ big post-grad research depts. so internationally their reputation is very good. Also, internationally many countries have only a “public” University system so students don’t differentiate.
Price: The Cals, UCLA, UMich, UVa, UNC of the world are ranked up with or higher than many more expensive privates (even for OOS) So a kid from Oregon or China, if they don’t expect need or merit money, pays 10k-15k less to go to ULCA or UNC than NYU or BC. (A full-pay OOS student picking #30 UNC over #32 BC saves 20k a year!) 30-80k over 4 years is real money for even upper middle-class families. And in state,of course, becomes very significant.
Increasing population. CA, while the rate of growth has leveled off, is still growing. We added 6 million residents this century? Add increased international applicants and US pop growth overall also contibutes.
The on-line app process has made it easier for international students. UCLAs 100k applications is due, in part, because of rising middle class in India + China etc., strong international rep and relative ease of applying. (UCLA, for instance, reports 47k CA res, 6k OOS and 4K international applicants in 2010, 59k CA res, 21k OOS, 17k Int. in 2016… CA apps are up marginally, OOS and Int exponentially…)
BTW, this is why I argue UCs - esp UCB and UCLA should increase OOS tuition. Rep is higher than many more expensive privates and folks will pay for the name. There’s really no reason UCB should be 10k a year cheaper than BU or Tulane. Even at 5k a year cheaper (UMich tuition) those schools would be over-subscribed.
