Black women write back the most. Whether its due to talkativeness, loneliness, or a sense of plain decency, black women are by far the most likely to respond to a first contact attempt. In many cases, their response rate is one and a half times the average, and, overall, black women reply about a quarter more often that other women.
White men get more responses. Whatever it is, white males just get more replies from almost every group. We were careful to preselect our data pool so that physical attractiveness (as measured by our site picture-rating utility) was roughly even across all the race/gender slices. For guys, we did likewise with height.
White women prefer white men to the exclusion of everyone elseand Asian and Hispanic women prefer them even more exclusively. These three types of women only respond well to white men. More significantly, these groups reply rates to non-whites is terrible. Asian women write back non-white males at 21.9%, Hispanic women at 22.9%, and white women at 23.0%. Its here where things get interesting, for white women in particular. If you look at the match-by-race table before this one, the should-look-like one, you see that white women have an above-average compatibility with almost every group. Yet they only reply well to guys who look like them. Theres more data on this towards the end of the post.
