What is the University of Southern ranking on world olympic medals?

There isn't a formal ranking of universities based on Olympic medals won by their alumni. While many universities track their alumni's Olympic achievements, there's no single, universally accepted ranking system for this. Such a ranking would be complex to create due to factors like:

* Defining "alumni": Should it include only graduates, or also former students who didn't graduate?

* Attributing medals: Some athletes may have attended multiple universities. How would medals be assigned?

* Data collection: Comprehensive and accurate data across all universities globally would be a significant challenge.

Therefore, you won't find a definitive "University of Southern California" (assuming that's the university you mean) ranking on a world Olympic medals list. You might find articles or university publications mentioning their successful Olympic alumni, but not a formal global ranking.
