Policymakers at the state and federal levels are showing increased interest in programs designed to encourage family formation among unmarried parents through interventions like marriage education, relationship skills, co-parenting, and responsible fatherhood programs. Interest in unmarried parents is based on a concern that children in single-parent households do not fare as well as children raised in two-parent households. This study examined the attitudes, perceptions, and barriers of 2,000 low-income never married mothers and fathers in Louisiana. The major purpose of the study was to contribute to the national debate about the most effective way to design and deliver services to promote family formation among low-income unmarried parents.
