https://yaledailynews.com/blog/2021/11/10/reluctance-on-the-... seems to say that in 2019 there were about 5900 undergrads and 5000 administrators and managers at Yale. Not quite parity.

But https://www.yale.edu/about-yale/yale-facts shows somewhat different numbers.

I was remembering this article:

But digging in it seems they may have been a little sloppy in their statement.
