Fact check time.
Two metros are home to more than one million college students — greater New York City with 1.3 million and greater Los Angeles with nearly 1.1 million. Both of these metros contain multiple major schools, like New York's Columbia University, New York University, and Barnard College and L.A.'s UCLA, USC, and Loyola Marymount University, just to name a few.
Chicago is next with more than 670,000 students, followed by Washington, D.C., and Philadelphia, each home to slightly more than 450,000 college students. Boston is next with nearly 400,000 college students.

Even if you don't include "metro areas", NYC still has well over double what Boston does.
