[Excerpt] In 2013, almost 25% of families with children (under age 18) were maintained by mothers. According to some estimates, about 60% of children born during the 1990s spent a significant portion of their childhood in a home without their father. Research indicates that children raised in single-parent families are more likely than children raised in two-parent families (with both biological parents) to do poorly in school, have emotional and behavioral problems, become teenage parents, and have poverty-level incomes. In hopes of improving the long-term outlook for children in single-parent families, federal, state, and local governments, along with public and private organizations, are supporting programs and activities that promote the financial and personal responsibility of noncustodial fathers to their children and increase the participation of fathers in the lives of their children. These programs have come to be known as “responsible fatherhood” programs. Sources of federal funding for fatherhood programs include the Temporary Assistance for Needy Families (TANF) program, TANF state Maintenance-of-Effort (MOE) funding, Child Support Enforcement (CSE) funds, and Social Services Block Grant (Title XX) funds. The federal government’s support of fatherhood initiatives raises a wide array of issues. This report briefly examines the role of the CSE agency in fatherhood programs and discusses initiatives to promote and support father-child interaction outside the parents’ relationship.
