"Boys are more likely to steer clear of trouble with the law when they grow up with their father in the home. One Princeton study found that boys raised apart from their fathers were two to three times more likely to end up in jail before they turned 30.
Dads matter for daughters as well. Another study found that girls whose fathers disappeared before the girls turned 6 were about five times more likely to end up pregnant as teenagers than were their peers raised with their fathers in the home."
Being born out of wedlock is not the same as being born to single parents. My sister was born in 2005 out of wedlock but my mom and step dad are still together 12 years later (and they eventually married too).
