  • Abstract

    The Survey of Program Dynamics (SPD) provides estimates of the economic status and activities of the population of the United States. SPD provides monthly labor force data and, in addition, supplies supplemental data on work experience, income, and noncash benefits. Comprehensive work experience information is given on the employment status, occupation, and industry of persons 15 years old and older, as well as weeks worked and hours per week worked, reasons for not working full-time, total income, and income components. Information is available not only for persons currently in the labor force but also for those who are outside the labor force. Variables cover unemployed respondents' current desire for work, their past work experience, and their intentions for job-seeking. SPD also provides data covering nine noncash income sources: food stamps, school lunch programs, employer-provided group health insurance plans, employer-provided pension plans, personal health insurance, Medicaid, Medicare, CHAMPUS or military health care, and energy assistance. Basic demographic, social, and economic characteristics are supplied for each member of the household surveyed, including 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.

Sampled Universe
Population of the United States, including children, who resided in civilian and military households and in group quarters in March 1992 and March 1993, except those living in military barracks and institutions such as prisons and nursing homes.
The SURVEY OF PROGRAM DYNAMICS (SPD), 1997: BRIDGE SURVEY (ICPSR 2797) interviewed approximately 29,619 households from retired 1992 and 1993 Survey of Income and Program Participation (SIPP) panels, which were scientifically selected on the basis of area of residence to represent the nation as a whole. From the households interviewed in 1997, a subsample of 19,129 households was selected for the continuing sample. Low-income households and households with children were selected with certainty or near certainty. Middle- and high-income households without children had a 1-in-4 chance of being selected for the sample.
Collection Mode
  • (1) The 1998 SPD is an unedited file. It is intended as an experimental file to allow experienced users to conduct longitudinal analyses by matching to the SURVEY OF PROGRAM DYNAMICS (SPD), 1997: BRIDGE SURVEY (ICPSR 2797) and the SURVEY OF INCOME AND PROGRAM PARTICIPATION (SIPP) 1992 PANEL (ICPSR 2037) and 1993 PANEL (ICPSR 2421) longitudinal files on the following keys at the person level: SIPP panel number, sample unit identification number, person number, and entry ID (SIPP_PNL, PP_ID, PP_PNUM, and PP_ENTRY). (2) The 1998 SPD file is a rectangular person-level file with household variables included on each person record (there are no family-level variables in the file). In contrast, the 1997 SPD Bridge file was structured as a hierarchical file. (3) The database dictionary is provided as an ASCII text file, and the codebook is provided by the principal investigator as a Portable Document Format (PDF) file. 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 on the ICPSR Web site.

2000-12-04 While reviewing the 1998 data the Census Bureau staff discovered a problem with the Industry codes, along with other minor problems. The data, database dictionary, and codebook have been replaced.
