This year the University of California president's office published an employment analysis of university personnel. I have examined these data and made some quick calculations; the results are suggestive, especially in light of the continuing budget crunch.
UC employs 113,227 people of whom 36,233 are students. Thus, the number of non-student employees is 76,994.
Eliminating researchers, librarians and cooperative extension personnel left me with three categories: administrative, staff and teaching. The total personnel in these three categories is 70,420.
