People who are married or in a defacto relationship can be matched to their partner via:
_hhpxid, the partner’s cross-wave identifier, or
_hhprtrid, the partner’s two-digit person number, which can be appended to the end of the household identifier
_hhrhidto create the partner’s identifer for that wave.
A partner identifier is only available for partners living in the same household. Same sex couples have a partner identifier.
Note: Replace the underscore with the appropriate letter for the wave, where ‘a’ corresponds to Wave 1, ‘b’ corresponds to Wave 2, and so on.
