FAMILY ID

This identifier is an unique ID number for each family in a Household/Dwelling.

Family IDs only relate to families within a household (see Household ID [ABSHID]). Families are only assigned an ID number in cases where households have more than one family.

Single family households are assigned a value that indicates the household has only one family.

People in households who are not members of the family or families in the household are assigned a value to remove them from family identification. Group households and Lone person households are also assigned this number.

Special dwellings are also removed from family identification (see Residence Status [URSTATC]).

Family IDs are time dependent and are assigned on a monthly basis. This is to account for changes in household and family structure across the months of selection. The combination of month (see Survey month ID [ABSMID]), household (see Household ID [ABSHID]) and family identifiers are required to uniquely identify families in the CURF. For more information, refer to File Structure and Identifiers.

For more information on families and how ABS defines household and family characteristics, refer to the publication Family, Household and Income Unit Variables, 2005 (cat. no. 1286.0).
