The Survey of Income and Program Participation (SIPP) is an ongoing longitudinal, nationally representative survey of between 20,000 and 40,000 households that has been conducted since 1983. In analyzing children in TANF child-only cases with relative caregivers, only the new panel that ran from 1996 to 2000 is relevant. The panel was modified soon after its fielding to account for changes in program details and eligibility with the passing of PRWORA. This panel consists of over 40,000 households comprising 95,000 individuals who are surveyed every 4 months. The core set of questions obtains extensive information on income and assets from all sources, labor force attributes, family structure, health insurance, and education. More detailed questions (modules) on special topics were asked periodically. The child well-being module, including questions on each child's TV viewing, reading or being read to, and activity participation, was included twice between 1996 and 2000. Questions of basic needs and food availability were asked in an adult well-being module once during the period. In the 1996û2000 panel, the survey contained approximately 1,000 children who did not live with any parent.
