This Urban Institute analysis of data from the 1999 National Survey of America's Families finds that many families who leave welfare return when their circumstances shift?—especially those with little education, limited work experience, and poor health. Families receiving transitional supports such as child care, health insurance, and emergency help with expenses were less likely to return, suggesting that many Temporary Assistance for Needy Families (TANF) leavers need ongoing assistance to help keep jobs and meet housing, child care and food costs.
