<p>So many of these questions have been asked and answered in recent months, and if you do a quick search of the past threads here, you will find them. Since I noticed the OP's screen name is bluesweetie, I figured we might be related, so I'll answer your questions: </p>
<p>(1) There are ~17,000 undergraduates (not counting grad students here)-- and no, this is not a commuter campus. The campus definitely does not empty out on the weekends.</p>
<p>(2) Many in-state and OOS students choose to leave NC after graduation, but often return years later. Still others (in-state or OOS) choose to stay, for either work or graduate/professional school, and then those people stay on forever. While it's often hard to get people to leave Blue Heaven once they've arrived, there is a very strong alumni network all over the US and beyond. Truly. I could give you specific examples, but pm me if you want those.</p>
<p>(3) This last question has been discussed so many times here, it's beginning to get really old. I just answered this question myself a few days ago. Check out my answer as it's still on the front page of this board somewhere.</p>
<p>No, people are not cliquish (or certainly not any moreso than anywhere else); many NC resident students are not native North Carolinians. NC has grown tremendously over the last 10+ years, so many people who live here aren't actually from here. They are from all over the US and outside the country. The US in general is a very mobile society. No one will even notice if you're from someplace else, unless you want them to notice, or you wear a sign around your neck. You will not have trouble making friends.</p>
<p>I am not a student, but I think I'm pretty much on the mark here with my answers. I'm sure students will chime in any second, though.</p>
<p>It's a wonderful campus, and students are generally really friendly and happy. Honestly, I think UNC-CH students are ranked #8 or something on the undergrad campus happiness scale.</p>
