We got our first information a half century ago about the impact on children of their parents not being married from The Moynihan Report, directed by sociologist Daniel Moynihan, who also served under Presidents Kennedy, Johnson, and Nixon. The Moynihan Report concluded that in a majority-black community the main predictor of growing up poor was not race but being born to parents who are not married. Why? A predictable outcome of no marriage was no father involvement.
