A few schools that haven't been mentioned yet that confer a good percentage of their degrees to math / statistics majors:
SUNY - Stony Brook
UCSB
Macalester
St. Olaf
Emory
UCLA
Dartmouth

Princeton, Cambridge, Harvard, UChicago, MIT, Caltech, Berkeley, Columbia, are top tier, assuming you take the most rigorous freshman math course (MAT 215, math 55, math 20700, etc)

Note that at MIT, a large portion of the highest achieving math majors know each other from math camps, MOP, etc, and a lot of the rest of the department is mainly those interested in applied math, CS/math double majors, etc

MIT and Princeton……the rest is ……..the rest

Amherst

Carnegie Mellon
Harvard
MIT
Rice
U Chicago
U Rochester

If wanting to take your math degree in a financial direction, I would add Bucknell and Colgate.

Such a weird list. How is Wash U higher than Princeton in math.

These are not the best schools for math. Mudd has a stake, but Berkeley, Princeton, and MIT are in conversation.

Doing what with the math degree?

I graduated from UMD CP and work in IT. I don’t use math but use my analytical skills I love what I do and get paid very well. It really depends on what you mean by math.

MIT is really the king.

Be a lot more specific about what you are looking for.
