title: Survey of Program Dynamics (SPD), 1997: Experimental File [Bridge Survey]
title: Version 1

description: This dataset is the bridge between the Survey of Income and
 Program Participation (SIPP) 1992 and 1993 panels and the Survey of
 Program Dynamics (SPD) 1998-2002 annual surveys. The data collected in
 the 1992 and 1993 SIPP panels provide extensive background information
 from which to determine the effects of welfare reform. Interviewing
 the same households in the SPD will provide data covering the baseline
 pre-reform period, the reform implementation period, and the
 medium-term post-reform period. The data from SPD present 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 over, 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. Questions cover respondents' current desire for work, their
 past work experience, and their intentions for job-seeking. SPD also
 contains 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.
description: The Survey of Program Dynamics (SPD) interviewed
 approximately 30,125 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.

description: (1) In this hierarchical dataset, there are three
 record types. The first record type is Household, with 153 variables
 in 37,830 records. The second type is Family, which has 68 variables
 in 33,061 records. The Person record consists of 395 variables in
 77,630 records. The entire dataset contains a total of 148,521
 records. (2) The dataset is a calendar-year file for 1996 intended to
 be used as a research file. Longitudinal analyses can be performed by
 linking this dataset to the SURVEY OF INCOME AND PROGRAM PARTICIPATION
 (SIPP), 1992 (ICPSR 2037) and SURVEY OF INCOME AND PROGRAM
 PARTICIPATION (SIPP) 1993 PANEL, LONGITUDINAL FILE (ICPSR 2421) using
 the following match keys: SIPP panel number, sample unit
 identification number, person number, and entry address ID (SIPP-PNL,
 PP-ID, PP-PNUM, and PP-ENTRY). (3) The data were collected using a
 modified Current Population Survey March questionnaire. This file was
 processed using programs for the March Current Population Survey
 Demographic Supplement. These data have undergone limited editing and
 review by the Census Bureau and should be used carefully. (4) Data on
 employment and income refer to the preceding year, although
 demographic data refer to the time of the survey. (5) The codebook is
 provided 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 through the
ICPSR Website on the Internet.
