Here's a recent Federal Reserve study on this topic. Net-net: it's essential for parents to review the financial strength of the university your kid is applying to because the enrollment decline is real. It's somewhat counter to the point that Selingo makes in his book, where you should find these small hidden jewels where your kid will be valued, because it's exactly those institutions that are at major risk of closing. Kind of like the example of Birmingham Southern University that Selingo gives in his book ... but if you read the book, BSU is exactly the sort of school that he encourages you to look at because it was small and valued the students it enrolled. So, go figure!
