Q. Are there any statistics stating that students would rather live on campus than off?
I did find an issue of Dateline (the UHD student newpaper) that addresses the topic. You can access it here: https://www.uhd.edu/student-life/dateline/Documents/issue50-4.pdf. I found this link by searching the UHD website for "dorms." You can try searching the UHD website using similar words to see what you can find. You could also look for information about the future of UHD on the website. Look for information on campus planning, campus initiatives, construction, and other like terms.
If you want general information about how students feel about living on campus/having on campus housing available, you could search LibSearch (the default option on the library homepage) for terms such as the following:
college housing opinion
study college housing
