So to kill some time in the waiting game, I was looking at admissions411 stats. The site seems to have fallen in usage a lot compared to last year, but I took a look at relative statistics among schools.
I took the top 10 schools by applicants (dropping Tuck and Columbia because I can't figure out how to match stats because they have ED), and divided the number of applicants in R1 this year by the number of applicants last year. Below are the schools and ratios. The higher ratios indicates an increase in apps relative to other schools. I'm sure there are tons of biases in this "study," but I thought it would be fun to play around with. So here it is:
Michigan - 0.49
Cornell - 0.48
Wharton - 0.42
Fuqua - 0.41
Chicago - 0.37
Kellogg - 0.36
MIT Sloan - 0.35
Harvard - .33
Haas - 0.29
Stanford - 0.28
NYU Stern - 0.27
Assuming all schools saw some sort of increase, Michigan has the biggest relative to other schools, and Stanford had the smallest.
Edited to add NYU, Haas, and Cornell
