  • Abstract

    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.
  • Methods

    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.

Sampled Universe
The universe consists of people residing in the United States, except people living in institutions, such as prisons, and nursing homes, and entire military households, in March 2001.
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.
Collection Mode
  • 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.
