The relational well-being of families is an important factor affecting a family's economic success, physical and mental heath, the readiness and success of children in school, and the engagement of youth in positive and productive roles. In short, the strength of family bonds is crucial to a family's capacity to provide, nurture, and care for its members. "Strong Family Relationships" is defined as the relational well-being of families. While the successful promotion of "strong family relationships" is clearly tied to ensuring family economic success and family health, this brief focuses primarily on strengthening the formation of families, the interaction of parents and children, the connection of families to social networks, and the adequacy and quality of necessary family resources. Addressing these many facets of family life is important given the dramatic changes and pressures associated with contemporary American family life. For example, fewer couples are marrying or are choosing to marry at later ages, more are cohabiting, increasing numbers of children will spend some part of their childhood in a single parent home, and rising health care, housing, and child care costs are making it difficult for families to balance the competing demands of work and family. This brief is a companion to a complete policy and research paper that provides an overview of current trends affecting American families and offers a beginning framework for state policies that strengthen family relationships.
