Study shows that whites who are fatter, less educated, less religious, and more liberal tend to be more likely to date blacks

Feliciano, Robnett, & Komaie (2009)

"One of the most striking findings is that white women who describe themselves as slim, slender, athletic, fit or average are nearly seven times as likely to exclude black men as dates as women who describe themselves as thick, voluptuous, a few extra pounds, or large"

"White women who state a religious preference are over two times as likely to exclude blacks, while white men who state religious preferences are over four times as likely to exclude black women as dates.... white men with an education preference are nearly five times as likely to exclude black women as dates as those who do not have an education preference."

"White women who describe themselves as liberal or very liberal are less likely to exclude black men as dates than women who are not political, middle of the road, or conservative"
