I think at a large U there tend to be more diversity, it would be easier to find one’s tribe. At my kids’ 13K students school, people can go to fraternity parties, get together with friends to play video games, go to dance recitals or go to libraries on weekends. When I went to a small 2500 students school, social life was a lot more limited. We all ate at the same dining hall, went to the same parties and lectures/recitals. I ended up partying quite a bit the first few years. It is why I don’t necessary think small schools are better for non-partiers or shy students.
