As soon as you step onto Columbia's campus, the diversity of the student population is immediately noticeable. Students at Columbia represent 50 states and 150 countries. Accordingly, Columbia boasts to be the most diverse Ivy League college. Walking through campus, one hears a variety of languages being spoken and can see tons of fliers advertising cultural events and organizations. Despite this diversity, the largest represented ethnicity remains Caucasian. That being said, Columbia is incredibly tolerant of people from all walks of life.
This tolerance likely speaks to the nature of the location of Columbia. With a population of more than 8 million people, New York is one of the most diverse cities on the planet, and Columbia aims to be a microcosm of that.
