Those are the men who "stuck around". You're not going to see all the deadbeats who are having babies with multiple women in a maternity ward.

Odd thing to but-for him about. About one in five American mothers have children from more than one father, and that includes Very Upstanding(tm) folks who divorce and remarry and not the women falling for those absolute chads of your projection.

A bit of a sidetrack, but that seems like a pretty high number to me. At least in my part of the world, the numbers are at least an order of magnitude lower.

Probably is high. Americans seem to divorce a lot.
