For fathers, it's "the best of times and the worst of times."
So says the National Fatherhood Initiative of Gaithersburg, Md., echoing the opening lines of Charles Dickens' "A Tale of Two Cities."
Today, many dads are more engaged than ever in their children's lives. They put bread on the table, as their grandfathers did, but they also diaper the baby, coach soccer and help with birthday parties.
At the same time, father absence has hit record levels. About 25 million children -- roughly one in three -- are not living with their biological fathers, according to the U.S. Census Bureau.
Until recent decades, fatherhood was one of the most venerated social institutions in America. But today it's under assault. The reasons range from the sexual revolution and economic changes to the rise of the divorce culture. Sixties-era feminism also has played a role, with its view of men as expendable and of traditional sex roles as oppressive. If men and women are the same, who needs dad?
Now a mountain of social science evidence is confirming what our parents and great-grandparents understood: Dad's presence is central to kids' well-being. Children with involved fathers have lower rates of juvenile delinquency, substance abuse and early sexual activity.
They also tend to have higher academic performance, greater self-control, more effective ways of dealing with frustration -- even better wages and greater empathy as adults.
Both boys and girls benefit from their fathers' involvement. Math competence in girls appears to be linked to early connections with the father. Daughters with engaged dads also tend to reach puberty later. Early onset of puberty is associated with higher rates of depression, teen pregnancy and alcohol consumption.
