Survey of Income and Program Participation (SIPP) 1985 Full Panel Research File (ICPSR 9395)

Principal Investigator(s):


This dataset contains basic demographic, social, and economic data for each member of interviewed households in the first eight waves of the 1985 Panel of Survey of Income and Program Participation (SIPP). Variables include age, sex, race, ethnic origin, marital status, household relationship, education, and veteran status. Limited data are provided on housing unit characteristics such as number of units in structure and tenure. Core questions, repeated at each interview, include monthly labor force activity, types and amounts of monthly income, and participation in various cash and noncash benefits programs for each month of the survey period. Data for employed persons include number of hours and weeks worked, earnings, and weeks without a job. Nonworkers are classified as unemployed or not in the labor force. In addition to income data associated with labor force activity, nearly 50 other types of income data are provided. Several variables are included for use in identifying longitudinal households and persons in them and to aid in analysis.

Data Collection Notes:

The period covered by the 1985 longitudinal panel file consists of 32 interview months (eight interviews) for Rotations 2, 3, and 4 of the survey. Rotation 1 has only 28 interview months (seven interviews). Specific months available depend on the person's rotation group and his or her sample entry or exit date. However, data from all four rotation groups (i.e., the full sample) are available only for reference months January 1985 through April 1987, inclusive. Also, the availability of data on household composition begins with the first interview month of a rotation group.


Sample:   The survey used a multistage stratified sampling design. Approximately 17,800 living quarters were selected for the sample. Of these, approximately 13,400 were occupied and eligible for interview. Each household was assigned to one of four rotation groups, and each rotation group was interviewed every four months. Thus one-fourth of the households were interviewed each month, and households were re-interviewed at four months intervals.
