It's what the exit polls say, although the main lesson we've learned this year is not to trust polls.

What's clearer is that Trump made big gains in areas of the country with a high Latino and Hispanic population - e.g. Santa Ana county, CA, which is 77% Hispanic, saw a 13-point swing to Trump, and there are many similar datapoints from across the country. It's pretty clear Trump carried Florida on the strength of the Latino vote in that state. There's also similar evidence that Trump made big gains this year among Asians.

So to summarise: Trump definitely made gains among Hispanics and probably made gains among Asians according to voting data; he made gains with every demographic except white men according to exit polls; the former data is more reliable than the latter.
