Description

Definition

PRMFAMSZ is the size of the primary, or first, family in the household. It is the FAMSIZE of the first family unit (FAMUNIT) recorded in the household.

PRMFAMSZ and FAMSIZE are constructed from information in RELATE (relationship to head of household) and from the constructed pointer variables SPLOC, MOMLOC, and POPLOC (location of spouse, mother, and father).

Note: Users should be aware that in the United States census of 1880, where relationship to the head was not transcribed for non-relatives, FAMSIZE and PRMFAMSZ may be inaccurate in some cases.
