HRHHID is a 15-digit numeric variable.
HRHHID is part 1 of the CPS household ID on the original files. When combined with HRHHID2, HRHHID can uniquely identify households within basic monthly samples.
In basic monthly samples from 1978 to 1984, there are blanks and dashes within the original data. These values have been replaced with 9's and 8's, respectively, for HRHHID in these years.
HRHHID and HRHHID2 codes are not unique across states in the April 1994 - May 1995 basic monthly samples. Researchers hoping to uniquely identify households in these samples should include STATEFIP as an additional household identifier.
