National Survey of America's Families (NSAF)The National Survey of America's Families (NSAF) is part of The Urban Institute's Assessing the New Federalism (ANF) multi-year research project. Its purpose is to track the effects of recent federal policy changes decentralizing many social programs from the federal government to the states, focusing primarily on health care, income security, job training, and social services. In collaboration with Child Trends, researchers from the Urban Institute monitor program changes and fiscal developments, along with changes in the well-being of children and families. The NSAF is a household survey that can be used to produce cross-sectional estimates for a wide variety of child, adult and family well-being indicators at the state level for 13 states and the nation as a whole.
