"Administration" strikes me as too broad to make a reasonable comparison before and after PCs. I would expect that in the same time frame that office PCs came into existence, the roles of colleges has also expanded greatly, and if those new roles are considered as part of "administration" I don't think the comparison tells you much about the effects of computers. Are we counting things like counseling, career planning, financial aid, health (including mental health), immigration services, legal and compliance work, everything related to sports and athletics, etc.?
