* Different Degree Types: Colleges offer associate's degrees, bachelor's degrees, master's degrees, doctoral degrees (PhDs, EdDs, etc.), and professional degrees (MD, JD, etc.). Each of these broad categories contains numerous specializations.
* Specializations within Degrees: Even within a single degree type like a Bachelor of Arts (BA), there are countless specializations (majors and minors). For example, a BA could be in History, English Literature, Psychology, Biology, etc., each with further sub-specializations.
* Colleges Vary: Different colleges and universities offer different degree programs. A small liberal arts college will offer far fewer degrees than a large research university.
Therefore, it's impossible to give a precise number. It's in the thousands, if not tens of thousands, of unique degree programs globally.
