2016 White and Non-White Vote by County Project

I'm surprised Trump didn't win Worcester and Hampden counties in MA- Worcester is somewhat similar demographically to Plymouth (both are 85% white and voted slightly over 40% Trump), and Hampden is around 70% white and virtually all the Democratic voters there live in the majority-minority areas like Springfield and Holyoke.

Based off that map above, it almost seems like MA's swing is due to a growing nonwhite population. Only two counties swung D (Norfolk, where I live, and Middlesex) while the rest of the state (even Suffolk, which has Boston) swung R. According to census estimates, the black population in Plymouth County grew from around 7% of the population to 10% (though they are pretty much entirely in Brockton, the largest city), though it is possible the model is off since some lily-white areas swung pretty strongly to Clinton.
