For all persons, RACEIMPUTE reports if the person's ethnicity or race was provided in the survey, or if her/his ethnicity or race was imputed. Beginning in 2017, NHIS has suppressed imputation flag variables indicating whether an ethnicity or race response was imputed; these variables are no longer available on public use files.
