Chicago’s core has 6 humanities and 3 social studies courses, for a total of 9 courses. But Chicago is on the quarter system, so this is probably equivalent to 6 courses at a semester system school. It also has a foreign language requirement (third quarter equivalent).
Columbia’s core has 7 humanities and social studies courses, and a foreign language requirement (second semester equivalent).
For comparison, MIT’s HASS requirement has 8 courses, but no foreign language requirement.
In other words, the volume of humanities and social studies required at these schools is not hugely different.
