Codes and Frequencies
HISPOVERSAMP reports the Hispanic oversample status for all persons in the 1992 National Health Interview Survey (NHIS). A value of 1 identifies the Hispanic oversample subjects. Values of 2 or 3 indicate those who resided in Hispanic households but who were not part of the oversample. A value of 4 indicates a non-Hispanic household.
The Hispanic oversample is described on page 2 of the introduction to the NHIS 1992 survey documentation:
IPUMS NHIS has retained the Hispanic oversample, in spite of these cautions. There are 7,712 subjects in the Hispanic oversample, representing 3.3 percent of the weighted population for 1992.
Users may choose to exclude the oversample using the HISPOVERSAMP variable to identify this subgroup. However, as noted above, if members of the oversample are excluded, the sampling weights will be incorrect. Conversely, users may choose to keep the full sample, with the knowledge that some subjects may be represented twice. The impact of keeping the oversample will be negligible for population-level analyses, even when combining multiple years of data. However, analyses of the Hispanic subpopulation for the two-year period of 1991-1992 may be affected by standard error estimates that are too small.
