How this variable is created

This variable is derived from family/household reference person indicator (RPIP) and relationship in household (RLHP). Individuals coded in RPIP as a family reference person in either the primary or non-primary family, and whose RLHP indicates a registered marriage or de facto relationship, are assigned the category ‘Family reference person’. Those coded as other household members who are in a registered marriage or de facto relationship are assigned the code ‘Spouse/partner’. 

History and changes

This variable was first introduced in 2021.
