American in-group dating bias is up about 25% or more this year, (or conversely, out-group dating is down) and the spread continues to expand. The exception being Asian women for both white and asian men, and white men in general. The numbers are distorted believe it or not by lower dislike of blacks by whites than dislike of blacks by asians and latinos. I’m getting most of this second and so I haven’t seen the data. And what I suspect, is that the numbers are being driven largely by increases in Latino and Asian populations on the west coast, both of which demonstrate more stratification in mating preferences than whites. But net of the data trend is that we overwhelmingly mate in-group.
