title: Version 1

description: The 2001 SPD Cross-Sectional file provides socioeconomic
 data for calendar year 2000. It contains basic demographic, economic,
 and social characteristics data for each member of the households for
 2000. The subject matter is described as follows: (1) Demographic data
 on age, sex, race, ethnic origin, marital status, household
 relationship, education attainment, and veteran status. (2) Economic
 data on work experience, including comprehensive work experience
 information on the employment status, occupation, industry, weeks
 worked, hours per week worked, total income, and income components for
 people 15 years old and older. (3) Income data covering income from
 jobs, net income from businesses, farm, or rent, and income from
 pensions, dividends, interest, and social security payments. (4) Data
 covering noncash income sources, such as food stamps, school lunch
 programs, employer-provided group health insurance plans,
 employer-provided pension plans, personal health insurance, Medicaid,
 Medicare, CHAMPUS/Tricare or military health care, and energy
assistance.
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 2001 who were represented by both the original and
 nonoriginal sample people in the SPD 2001 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 2001 cross-sectional file includes state
 identifiers and is weighted to current state (as well as national)
 controls, deriving sub-national 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, 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, including the SPD Bridge noninterviewed
 households brought back in the SPD 2000, and the SIPP noninterviewed
households brought back in the SPD 2001.

description: computer-assisted personal interview (CAPI)(1) The 2001 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.
