This graphic shows the lowest and highest response rates, meaning the percentage of people who respond when someone indicates interest after viewing their profile (in this case, showing interest means sending the other person a “yes” if you like their profile).
I found it particularly interesting that all races of men have the highest response rate to women outside their own race and only Asian men don’t have the highest response rate to Asian women. It was also interesting that black and white women were the only groups who had the highest response rate to their own race and black women had the lowest response rate to white men, which every other race of women responded to the most.
