Big state schools are also usually party schools, more so than smaller ones, so that shouldn’t really be taken into much consideration since peer pressure is huge even if you’re nerdy and awkward.
I found setting is more indicative of social scene: you’ll find that in suburban and rural schools on-campus activities are really important and encouraged. There is just nothing else to do in the immediate surroundings, so students stay on campus always, which is great for most people. In urban settings, however, students tend to hang out off campus and aren’t usually expected to participate in on-campus events, which is great for introverts like us.
