Johns Hopkins, nope, I was wrong. The University of Chicago, most definitelytwice as many grad students, a higher grad:undergrad ratio than MIT. Rockefeller University has no undergraduates at all, an infinite grad:undergrad ratio.  

 Hey! Columbia has over twice as many grads as undergrads. Hey, hey:  Harvard has almost twice as many. Yale 5316 undergrads, 6074 grads and University of Pennsylvania have more grads than undergrads. 

 :I bet the truth is closer to "Like most major research universities, MIT enrolls more grads than undergrads." 

 :That's just one point, but I have the feeling that there's it's not the only breezy shoot-from-the-hip unchecked fact in the article.
