Alternate Title

SPD 1999

Summary

The 1999 SPD Cross-Sectional file is a minimally edited file that provides socioeconomic data for calendar year 1998. It is intended for analyses of effects of welfare reform on individuals, families and households. The file can be linked to the SPD Third Longitudinal, the SPD Second Longitudinal, the SPD First Longitudinal, the SPD 1998, the SPD 1997 Bridge and the 1992 and 1993 SIPP Panel files. The file contains basic demographic, economic, and social characteristics data for each member of the households for 1999. 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 1999 for the 1998 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.

Data Collection Notes

  1. (1) The 1999 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.

Sample

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.

Universe

The Survey of Program Dynamics (SPD) 1999 cross-sectional universe consists of the civilian non-institutionalized population living in the United States in March 1999. 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.

Weight

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.
