I subtracted Jewish from white, since "Out of this 2,831,000 religious Jewish population, 92% are non-Hispanic white": https://en.wikipedia.org/wiki/American_Jews#Assimilation_and...

Where did you get the number of white? I'm saying you can't sum ethnicities because many people are multiple ethnicities.

Subtracted everyone else from 100%. I think they made people pick either only one ethnicity in their polls, or they were lumped under 'other'. The numbers I get are close to https://www.collegefactual.com/colleges/harvard-university/s..., so while not totally accurate, I'd say they're reasonably good.
