This is a sensitive topic for students who don't want to hurt their chances of admission, and don't want to be pinned with a label. The bottom line: the choice is yours to make.
Most college/admission guidebooks, general college search sites, and individual college websites and publications can be sources of information.
I caution students that they must first "know what you need." College is not about remediation for your learning issues; it is about accommodation.
How does "everything" sound? You can usually find a list of clubs and organizations on a college website.
You can measure a college's diversity in comparison to others in similar settings and who are similar types of colleges.
