  Human mating is a complex phenomenon. Although men and women have different
preferences in mate selection, there should be compatibility in these
preferences since human mating requires agreement of both parties. We
investigate how compatible the mating preferences of men and women are in a
given property such as age, height, education and income. We use dataset of a
large online dating site (N = 44, 255 users). (i) Our findings are based on the
"actual behavior" of users trying to find a date online, rather than questions
about a "hypothetical" partner as in surveys. (ii) We confirm that women and
men have different mating preferences. Women prefer taller and older men with
better education and higher income then themselves. Men prefer just the
opposite. (iii) Our findings indicate that these differences complement each
other. (iv) Highest compatibility is observed in income with 95 %. This might
be an indication that income is in the process of becoming more important than
other properties, including age, in our modern society. (v) An evolutionary
model is developed which produces similar results.
