From NCES navigator, MIT awarded the following number of bachelor’s degrees:
2 Visual and Performing Arts
14 Social Sciences (12 Econ)
0 Philosophy
6 Liberal Arts and Sciences
0 History
2 Foreign Languages and Linguistics
2 English
This is out of ~1100 graduates. Put another way, ~2.5% of students major in humanities and social sciences with almost 50% of those in economics. I agree with a previous poster–if you want history as your primary major, go somewhere else as you wouldn’t even have a small cohort of like-minded individuals.
