FAMSTRUCTR (HV217) indicates the relationship structure (no adults, one adult, two related adults of the opposite sex, two related adults of the same sex, three or more related adults, or unrelated adults) in the household. Only usual (de jure) household members aged 15 and over are considered in determining the household's relationship structure. FAMSTRUCTR is a constructed variable, based on information about each household member's age, sex, and relationship to the householder, which was collected when completing the listing of persons in the household at the time of the survey.
The information in FAMSTRUCTR is taken from the household record and applies to regular household residents, not temporary visitors. Researchers may wish to exclude visitors using the RESIDENT variable when women, children, or births are the unit of analysis, and using the HHRESIDENT variable when household members are the unit of analysis.
