Along the lines of my post from two weeks ago on women and marriage, The Atlantic has an article on women marrying less educated men.

Once upon a time, it was fairly common for highly educated men in the United States to marry less-educated women. But beginning in the mid-20th century, as more women started to attend college, marriages seemed to move in a more egalitarian direction, at least in one respect: A greater number of men and women started partnering up with their educational equals. That trend, however, appears to have stalled and even reversed in recent years. Gaps in educational experience among heterosexual couples are growing again. And this time? It’s women who are “marrying down.”
Researchers debate whether marriage between educational equals—homogamy—is on the decline. But one thing is clear: The phenomenon of women marrying men with less education than themselves, what academics call “hypogamy,” is on the rise. In fact, women are now more likely to marry a less-educated man than men are to marry a less-educated woman.
The reasons listed in the article are:
- Political divergence - men, especially young men are moving to the right whereas women are more to the left.
- Love - women's increasing economic security allowing them to marry who they love rather that "a good catch".
- Availability - Fewer educated men available per educated woman.
I would add a fourth namely that gender segregation in work. Most plumbers, electricians, carpenters and other skilled trade positions are dominated by men. Such jobs do not require college degrees but are very well paid.
