Asians are the only ethic group in which men’s same-race preference is (slightly) greater than the women of their race, with both close to 21%.Hispanic women have a lower stated same race preference than another ethnicity of women, but it is still greater than of Hispanic men.

If I then only try initiate relationships with men who are over 6’, say, then my revealed preference is for tall men, not short men.

The concept of revealed preference is an important one for economists, which is why we rarely rely on surveys to determine preferences.

If you ask an individual if they prefer to date someone their own race, the majority of people will say that they have no same-race preference.

In the online dating data we are talking about today, for example, among whites, 49% of all women and 22% of men declare a preference for white mates while only 30% of black women and 8% of black man declare a preference for black mates.

The very first post on Dollars and Sex asked the question: "Do Women Really Value Income Over Looks in a Mate?

" The research we talked about in that post also addresses the issue of interracial dating, so I thought it would be interesting to return to that paper again and ask a new question: Do women value ethnicity over income in a mate?

As I wrote earlier this week, one of the reasons economists like to use dating Web sites for data on mate choice is that people often don’t act in a way that is consistent with their stated preferences.

Say, for example, that I am asked the question “How tall does a man have to before you want to date him” and I respond that height doesn’t matter to me.

They find that after controlling for all other factors that might contribute to first email contact (age, marital status, income, education, children etc.) every ethnic group “discriminates” based on race.

Black and Hispanic men receive half as many first contact emails from white women as white men do and Asian men are contacted only about one fourth as often.

They also find the same result as the research we talked about in my last post, that women have a stronger same-race preference then men.
