I was recently made aware of a study (caveat: from 2014) indicating that, supposedly, US academic institutions have taken on non-academic staff at a much higher overall rate than the increase in the student population, counting from 1987 and unti 2011-2012.
Now, the think-tank which authored this study seems fishy to me, but I don't live and work in the US, so I wanted to ask for corroboration or refutation of its claims based on your experience and knowledge.
Note: Academic activity and number of students is not the same thing; information relative either to the former or the latter is relevant.
