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 post-secondary 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 series of supplemental questions asked during selected household visits.

Topical modules include some core data to link individuals to the core files.

The Wave 1 Topical Module covers recipiency history, which includes welfare and other aid, and employment history. The Wave 2 Topical Module includes data on work disability, education and training, marital, migratory, and fertility histories, and household relationships. The Wave 3 Topical Module covers work schedule, child care, child support agreements, support for nonhousehold members, functional limitations and disability, and utilization of health care services. The Wave 4 Topical Module covers selected financial assets, medical expenses and work disability, real estate, shelter costs, dependent care, and vehicles. The Wave 5 Topical Module covers annual income, retirement accounts, and taxes in one file and school enrollment and financing in the second file. The Wave 6 Topical Module covers the same subjects as the Wave 3 Topical Module, but in greater detail, and includes a section on children's well-being. The Wave 7 Topical Module covers assets and liabilities, medical expenses and work disabilities, real estate, shelter costs, dependent care, and vehicles. The Wave 8 Topical Module covers school enrollment and financing. The Wave 9 Topical Module covers retirement expectations and pension plan coverage, work schedule, child care, children's well-being, child support agreements, support for nonhousehold members, and basic needs, including ability to meet expenses, food adequacy, and minimum income.

In the 1993 Panel, the Core Microdata Files for Waves 4-7 have been redesigned for simplicity and consistency. These new files are called Core Person Month Microdata Files to reflect that the data have been coded to the monthly level. In addition, unedited variables were eliminated if they also appeared in edited form, and source codes and check items were removed as well.

The codebooks are provided as Portable Document Format (PDF) files. The PDF file format was developed by Adobe Systems Incorporated and can be accessed using PDF reader software, such as the Adobe Acrobat Reader. Information on how to obtain a copy of the Acrobat Reader is provided through the ICPSR Website on the Internet.

The documentation for Part 17, Wave 8 School Enrollment and Financing Topical Module Microdata File, also covers a Research Topical Module File that is not included with the data collection.

Beginning with the 1990 Panel, the file structure of SIPP was changed. The unit of observation is one record for each person for each month, rather than one record per person.

The machine-readable data dictionary associated with Part 7, Wave 4 Core Person Month Microdata File, also covers Waves 5-7 (Parts 9, 12, and 14).

A multistage stratified sampling design was used. One-fourth of the sample households were interviewed each month, and households were reinterviewed at four-month intervals. All persons at least 15 years old who were present as household members at the time of the first interview were included for the entire study, except those who joined the military, were institutionalized for the entire study period, or moved from the United States. Original household members who moved during the study period were followed to their new residences and interviewed there. New persons moving into households of members of the original sample also were included in the survey, but were not followed if they left the household of an original sample person.
