Exodius, very interesting data! I note a big change from 2012 to 2013… I wonder what Stanford did to increase their yield… as I said above, Harvard was beating Stanford 2-1 and Yale vs. Stanford was 50-50, and Stanford vs. Princeton was 7-3… but then something changed in 2013… Harvard still beats Stanford, but closer 6-4, Yale vs. Stanford is now 6-4 in Stanford’s favor, and Stanford is crushing Princeton 3-1.
What is interesting is The Ivy League yields are ALSO increasing… so I think this must mean the pool of overlap admits is drastically diminishing… which makes sense… with acceptance rates so low, very few students are being admitted to more than just a few of the elite schools.
O, and I completely agree this is more trustworthy than smarchment… but most schools do not reveal this data publicly, and smarchment is the only place to get it all in one place, albeit not as necessarily representative.
