Maybe it's just me, then. I know when I was looking at schools I didn't even consider the gender breakdown of the school. It wasn't anywhere near my top concerns - it wasn't even a factor I looked at.
Also, I'm not sure how valid the author's statement actually is. I didn't spend a ton of time researching it, but I was curious. Here are the application numbers for two recent years (couldn't find University of North Carolina):
Boston College | 38.2k -> 41.7k (+9%)
Brandeis University | 7.7k -> 8.9k (+15%)
New York University | 38k -> 42.2k (+11%)
University of Georgia | 17.4k -> 18k (+3%)
Each college continued to receive an increase in applications that was (with the exception of the University of Georgia) on par with other colleges.
If people are still applying to those schools, and they aren't seeing decreased applications, doesn't that mean the whole "tipping point" argument where no one will want to go to those schools is invalid?
