Many college students plan to spend about $10,000 or more this school year on room and board, according to a report from the College Board, a nonprofit organization that manages standardized tests used for college admissions.

The high price of living on campus can be worth it, though. Impromptu slumber parties and late-night game nights can make living at school a fun, bonding experience. Schools’ policies vary on whether living on campus is required, encouraged or unnecessary, but at some institutions students strongly prefer to live there.

At Harvard University, for example, 99 percent of undergraduates lived on campus in fall 2013. It had the highest percentage of undergraduates at a National University living on campus, according to data submitted to U.S. News by 252 ranked schools. National Universities offer a full range of bachelor’s, master’s and doctoral degrees.
