"Single parent homes" refers to families where one of the parents, usually the father, does not provide any financial or child care support at all. Typically happens when a couple gets pregnant out of wedlock and the father decides to take off. A family where dad (or mom) works on the other side of the world to put a roof over everyone's head does not count.
It disproportionately affects black and hispanic Americans.
