Sorry to disagree. "With access to six universities and twelve junior colleges in an 8 kilometer (5 mi) radius, Montreal, Quebec (Canada) has the highest proportion of post-secondary students of all major cities in North America. " All of the examples you gave are small college towns. 'Ames' 'Ithaca' 'State College' - those are not cities etc. Montreal has 6 major universities and other colleges crammed right downtown in a tiny radius. San Francisco does not have 300K students in the city. There are only 800K residents in SF, that would make almost 50% students :). The 'Bay Area' - sure. But the bay is huge - and not really even a city. Chicago is a massive, sprawling city with 600K students. Dallas-Forth Worth - again - massive, sprawling cities, geographically spread out. Montreal - not including the suburbs, just the city proper, has 100's of thousands of students. I think the only other city with the student density would be Boston and the numbers may be off because Harvard and MIT are technically in Cambridge, not Boston.
