Summary View help for Summary
The data files in this collection are individual-level extracts derived from the Current Population Survey's March Annual Demographic files for the years 1968 to 1992. Each record contains information about an individual, the household in which the individual resides, and the family and the spouse of the individual. In addition to the standard monthly labor force data, these files contain supplemental data on work experience, migration, income, and noncash income sources such as food stamps, school lunch programs, Medicaid, Medicare, CHAMPUS or military health care, energy assistance, health insurance, and pension plans.

(1) Data on employment and income refer to the preceding year while demographic data refer to the time of the survey. (2) These data files may be linked for cross-sectional analyses, with the restriction that the extracts are not completely uniform across the two revisions of the March Current Population Surveys. Three different versions were used during the periods 1968 to 1975, 1976 to 1988, and 1989 to 1992. Merging across versions requires careful attention to how variables were constructed and possible differences in universes for particular variables. (3) With the exception of 1974, the locations of variables in the data files differ between the time periods 1968 through 1988 and 1989 through 1992. Users of data for the years 1968 to 1973 and 1975 to 1988 should use the data definition statements for that time period (Parts 27 and 29). Likewise, users of data for the years 1974 and 1989 to 1992 should select Parts 26 and 28, the data definition statements that pertain to those years.
