Survey of Income and Program Participation (SIPP): 1991 Panel Wave 7

<p>This data collection is part of a longitudinal survey designed to provide detailed information on the economic situation of households and persons in the United States. These data examine the distribution of income, wealth, and poverty in American society and gauge the effects of federal and state programs on the well-being of families and individuals. There are three basic elements contained in the survey. The first is a control card that records basic social and demographic characteristics for each person in a household, as well as changes in such characteristics over the course of the interviewing period. The second element is the core portion of the questionnaire, with questions repeated at each interview on labor force activity, types and amounts of income, participation in various cash and noncash benefit programs, attendance in postsecondary schools, private health insurance coverage, public or subsidized rental housing, low-income energy assistance, and school breakfast and lunch participation. The third element consists of topical modules, which are a series of supplemental questions asked during selected household visits. Topical modules include some core data to help link individuals to the core files. A topical module was not created for the first wave of the 1991 Panel. The Wave 2 Topical Module (Part 5) covers employment, work disability, education and training, marital status, migration, fertility history, and receipt of benefits from government programs. The Wave 3 Topical Module (Part 9) includes data concerning work schedule, child care, child support agreements, support for nonhousehold members, functional limitations and disability, and utilization of health care services. Data in the Wave 4 Topical Module (Part 13) include selected financial assets, medical expenses and work disability, real estate, shelter costs, dependent care, and vehicles. The Wave 5 Topical Module (Part 17) covers annual income and retirement accounts, taxes, and school enrollment and financing. The Wave 6 Topical Module (Part 20) includes information on consumer durables, living conditions, and basic needs. The Wave 7 Topical Module (Part 22) focuses on assets and liabilities, retirement expectations and pension plan coverage, and real estate property and vehicles. The Wave 8 Topical Module (Part 24) covers school enrollment and financing. Part 26 of this study is the Wave 5 Topical Module Microdata Research File, an unedited version of Part 17. This research file has not been edited nor imputed but has been topcoded or bottomcoded and recoded if necessary by the Census Bureau to avoid disclosure of individual respondents' identities.
