Temporary Assistance for Needy Families (TANF) is a block grant created by the Personal Responsibility and Work Opportunity Reconciliation Act of 1996, as part of a federal effort to "end welfare as we know it." The TANF block grant replaced the Aid to Families with Dependent Children (AFDC) program, which had provided cash welfare to poor families with children since 1935.
Under the TANF structure, the federal government provides a block grant to the states, which use these funds to operate their own programs. States can use TANF dollars in ways designed to meet any of the four purposes set out in federal law, which are to: "(1) provide assistance to needy families so that children may be cared for in their own homes or in the homes of relatives; (2) end the dependence of needy parents on government benefits by promoting job preparation, work, and marriage; (3) prevent and reduce the incidence of out‑of‑wedlock pregnancies and establish annual numerical goals for preventing and reducing the incidence of these pregnancies; and (4) encourage the formation and maintenance of two‑parent families."
