Blah, I think this is really simplistic and assumes way too much and doesn't look at the big picture. The group that is delaying childbirth the most are college educated women. The assumption (which may or may not have value) is that college educated and career focused women are delaying childbirth to focus on finishing school and establishing their careers first, not that they are "bad at coupling up" because they have social difficulties. I have a personal hypothesis that college educated women may be "bad a coupling up" because they can afford to be more picky - they may not feel a need to get married or be in a relationship for economic security so they can delay "settling down with someone" until they find a more desirable partner. Or even that being college educated makes you have higher standards. (not sure about that part) Combine that with the fact that this group is very unlikely to have a child out of wedlock. http://www.theatlantic.com/sexes/archive/2013/03/getting-married-later-is-great-for-college-educated-women/274040/ http://www.theatlantic.com/sexes/archive/2013/03/getting-mar... >College-educated women are unlikely to have a child before getting married For college-educated women, the average age of first birth (30) has risen along with the average age of marriage (27). Only 12 percent of births by college graduates are to unmarried women. >Women without college degrees are very likely to have a child before getting married Less-educated women have a much different experience with marriage and childbirth. For women without a college degree, the average age of first birth has not risen apace with the average age of marriage. The average age of first birth for this group is lower than the average marriage age. For women who dropped out of high school, the average age of first birth is 20, while the average marriage age is 25; 83 percent of first births in this demographic are to unmarried mothers. For women who graduated from high school and went to some college, the average age for first birth is 24 and the average marriage age is 27; 58 percent of first births are to unwed mothers. (This isn't even taking into the consideration that the change in the diagnostic criteria for autism has changed...)
