Where are the older students? (22 yo transfer)

I know most are probably off the hill and dining halls. I made the mistake of living in a dorm and doing the dining halls. I’m surrounded by very young people most of the time. Some look like my little cousin who’s in high school. Where are the older students (21-22?). Is everyone off the hill at this point? My roommates are children as well. Is this it or are there older students out there? I relate more to my professors than freshman or sophomores at this point.
