IIR from the Pew Research Foundation on Family in the United States, less than fifty percent of all children in the US have two married parents, across all demographics and education levels, minus the one-percent highest income bracket.

lots of people in the city here with children, almost entirely the women.. the men are out of the picture for lots of reasons.. a non-zero percentage of young children have not met their biological father. The dental hygenist told me a month ago she has five kids of various ages and their father "lost his green card" and is gone.. she was cheerful and matter-of-fact. A plain spoken man in his fifties told me he has five children with three women and he never married any of them. This is not "terrible" it is true in his own words, he complains about the women and changes the subject.
