i think that happens when you have numerous colleges in a city.
but trust me, as a grad student in history, some advanced degress are less economically useful to a community....hehe
Yea, there may be more colleges than normal but man, we are talking percentages of the entire city here.
No matter how many colleges there are, that still could not impact the percentages for such a large city. That table is saying that 10% + of the entire city has Masters, Professional or Doctors degrees which is higher than the national average. My opinion is that a larger than normal number of university professors in town or whatever still could not cause that to be 2 % higher than the average.
