Matching and Sorting in Online Dating  

"Regarding height, we find that men typically avoid tall women, while women have a preference for tall men. Men have a strong distaste for women with a large BMI, while women tend to prefer heavier men. The estimates of income preferences show that women place about twice as much weight on income than men. [...] Regarding education, we find that both men and women want to meet a partner with a similar education level. While women have an overall strong preference for an educated partner, but also have a relatively small tendency to avoid men who are more educated than themselves, men generally shy away from educated women. The estimated same-race preferences show that both men and women have a preference for a partner of their own ethnicity. Finally, we find that both men and women have a preference for a partner of the same religion."--"Matching and Sorting in Online Dating" (2010) by Dan Ariely et al.
