anyone who graduated from Michigan State University

University of Michigan

You have to be a resident of the State of Michigan in order to receive in-state tuition.

The university may offer a scholarship to student whose parents are MSU alumni.

You can contact the university's 'Alumni Association'. They can supply a list.

Overall that would be hard to figure because many of the world's oldest universities probably do not have records regarding the number of graduates they have extending their entire history. The University of Michigan has the most living alumni of any university at nearly 500,000.
