Child welfare agencies in the United States are charged with ensuring the safety, permanency, and well-being of children who have been abused or neglected, and those deemed at risk of abuse or neglect. State child welfare agencies vary in their approaches to responding to and caring for abused and neglected children, as well as children at risk of maltreatment. There is great variation in the continuum of services provided to these vulnerable children and families, and also distinctions in how states finance their child welfare systems. Many sources of public funding are available to help support child welfare activities, making the overall approach to child welfare financing in the United States a web of federal, state, and local dollars. Understanding the ways in which state child welfare agencies fund services can help children’s advocacy organizations and other nongovernmental stakeholders deepen their knowledge of the child welfare system.
