The article I saw was this one - It claims 10,000 administrators and support staff compared to 7500 undergraduates. I'm guessing your numbers include all employees and all students, including graduate students? Clearly, one should compare administrators etc. who are focused on undergrads with the number of undergrads. The link below includes a reference to the original study, so I suppose one could tease out the proper numbers. But, in any case, there are a lot of administrators these days.
Thanks for the info.
