But according to separate research by University of Pennsylvania economist Jeremy Greenwood and by UCLA sociologists Christine Schwartz and Robert Mare, educational intermarriage is less common today than at any point over the past half century.
Regardless of orientation, not all women, of course, place a premium on marriage, or even monogamy.
But for the straight, college-educated woman who is eager to get married and start a family, the question becomes how best to deal with a dating market in which men have too much leverage.
When there are plenty of marriageable men, dating culture emphasizes courtship and romance, and men generally must earn more to attract a wife.
But when gender ratios skew toward women, as they do today among college grads, the dating culture becomes more sexualized.
The good news, at least according to the work of psychologists and sex-ratio pioneers Marcia Guttentag and Paul Secord, is that people tend to have better sex when ratios skew female. Women frequently wind up being treated as sex objects, and men are more inclined to exercise the option to delay marriage and play the field.
