title: Survey of Program Dynamics (SPD), 2000: Cross-Sectional File
title: Version 1

description: The 2000 SPD Cross-Sectional file is a minimally edited
 file that provides socioeconomic data for calendar year 1999. It is
 intended for analyses of effects of welfare reform on individuals,
 families and households. The file can be linked to the SPD First
 Longitudinal File (ICPSR 3315), the SPD Second Longitudinal File
 (ICPSR 3594), the SPD Third Longitudinal File (ICPSR 4470), the SPD
 1997 Bridge (ICPSR 2797), the SPD 1998 (ICPSR 2917), and the SIPP
 Panel files for 1992 (ICPSR 6429) and 1993 (ICPSR 6886). The file
 contains basic demographic, economic, and social characteristics data
 for each member of the households for 2000. The subject matter is
 described as follows: demographic data on age, sex, race, ethnic
 origin, marital status, household relationship, education attainment,
 and veteran status. Demographic data refer to the time of the
 interview in 2000 for the 1999 data year. Economic data include
 comprehensive work experience information given on the employment
 status, occupation, industry, weeks worked and hours per week worked,
 total income, and income components for persons aged 15 and over. The
 data on employment refer to the preceding year. Income data cover
 income sources such as income from jobs, net income from businesses,
 farm or rent, pensions, dividends, interest, and social security
 payments. Data on income refer to the preceding year. Noncash benefits
 data cover noncash income sources such as food stamps, the school
 lunch program, employer-provided group health insurance plan,
 employer-provided pension plans, personal health insurance, Medicaid,
 Medicare, CHAMPUS/Tricare or military health care, and energy
 assistance. Most data on noncash benefits refer to the preceding
year. However, some questions refer to the week before the interview.
description: The weights on this file are cross-sectional, therefore they
 are only valid for estimates of the characteristics of the cohorts of
 people in 1998 who were represented by both the original and
 nonoriginal sample people in the SPD 1999 sample. An original sample
 person is a sample person who was a self or proxy respondent in Wave 1
 of the SIPP 1992 or 1993 panel. A nonoriginal sample person is a
 sample person who became part of the sample after the SIPP Wave 1 and
 beyond (including the SPD samples). The SIPP 1992 and 1993 Panel
 samples, from which the SPD sample originated, were designed to
 produce only national estimates of the characteristics of interest to
 the user. Although this 1999 cross-sectional file includes state
 identifiers and is weighted to current state (as well as national)
 controls, deriving subnational estimates from this 9-year-old sample
 that has experienced severe attrition (household and person
 nonresponse) and other sample loss (through death,
 institutionalization, etc.) as well as sample cuts dictated by
 budgetary constraints, results in inadequate representativeness and
 poor coverage in some of the smaller geographic areas. Even for the
 national estimates, inadequate representativeness and poor coverage
 occur in children of all races as well as Black adults aged 20 to
 39. In addition to noninterview adjustment, the Bureau of the Census
 attempted to further correct for these deficiencies by bringing back
 noninterviews from the 1997 Bridge sample and from a subset of the
 SIPP 1992/1993 Panels. These sample cases are included in this
 cross-sectional file, and will be included in the third (and final)
longitudinal file, as well.
description: The universe is represented by original sample persons
 from the 1992 and 1993 Survey of Income and Program Participation
 (SIPP) panels and individuals who joined their households or group
 quarters later as a resident. Exceptions were those who were
 subsampled out because of (1) cost constraints, (2) leaving the
 universe associated with the SPD Bridge, and (3) they were part of the
SPD 1998 sample cut.

DS1: Survey of Program Dynamics (SPD), 2000: Cross-Sectional File
description: The Survey of Program Dynamics (SPD) 2000 cross-sectional
 universe consists of the civilian non-institutionalized population
 living in the United States in March 2000. The institutionalized
 population, which is excluded from the population universe, is
 composed primarily of the population in the correctional institution
 and nursing homes. The population universe also includes people living
 in group quarters, such as dormitories, rooming houses, and religious
 group dwellings. Crew members of merchant vessels, armed forces
 personnel living in military barracks, and institutionalized people
 such as correctional facility inmates and nursing home residents, were
 not eligible to be in the survey. Also, United States citizens
 residing abroad were not eligible to be in the survey. Foreign
 visitors who work or attend school in this country and their families
 were eligible, but all other foreign visitors were not eligible to be
 in the survey. With the exceptions noted above, people who were at
 least aged 15 (adults) at the time of the interview were eligible to
 provide self and/or proxy interviews for the survey. The data of
 people who were less than aged 15 (children) at the time of the
 interview were collected from proxy interviews provided by the
 adults. The population universe is represented by a subset of the
 original sample people from the 1992 and 1993 Survey of Income and
 Program Participation (SIPP) panels and the people who joined their
 households or group quarters later as a resident. Namely, the sample
 people who lived in the SPD 2000 sample households which consisted of
 the SPD Bridge sample households that survived the SPD 1998 sample
cut.
description: computer-assisted personal interview (CAPI)(1) The 2000 SPD Cross-Sectional file is minimally
 edited and is intended for analyses of effects of welfare reform on
 individuals, families and households. It can be linked to the SPD
 Second Longitudinal, SPD First Longitudinal, the SPD 1998, the SPD
 1997 Bridge, and the 1992 and 1993 SIPP Panel files. (2) The file is a
 rectangular, person-level file. Household- and family-level variables
are included on the record for every person in the household.
