WSJ.com - What Women Want: "When it comes to single-parent families, Everybody's Doing It. That, it seems, is the received wisdom -- but it's not true. As Charles Murray noticed decades ago and demographers have known for some time, the structure of families has diverged drastically by social class. The out-of-wedlock birth rate among women with no more than a high-school education has skyrocketed since the 1960s but remains very low among college graduates. Divorce has declined among the well-off but is climbing among the unskilled. Although almost all college graduates still marry eventually, marriage rates are dropping steadily among those without a high-school degree."
