Family ID within household

FAMILYID is a 4-digit numeric variable that represents the family number of the household member within a household, except for the following values:


9995 = No consent given (female questionnaire)
9996 = No consent given (household questionnaire)
9998 = No response or missing


FAMILYID identifies which family unit within the household the individual belongs to, because there can be more than one family within a household. Households are defined as a group of people who live and eat together in the same dwelling. A family is a group of people who live and eat in the same dwelling and are related by blood or marriage. In defining families using the FAMILYID variable, enumerators sometimes broke up groups of relatives into related subfamilies, each given their own FAMILY ID, as specified below.

Enumerators were instructed to define each family group within a household according to the following list of rules based on marriage and childrearing:

Draw a family tree while you are completing the household roster.

a. Start with the household head: The household head, her/his spouse, and their unmarried children who have no children of their own are defined as Family ID.
b. The first child of Family 1 to either (a) get married or (b) have a child, will be identified, along with her/his spouse and/or children, as Family ID 2.
c. In the case of polygamous households: A man may live with two wives and their children. The household head, his first wife and their children will be identified with Family ID 01. The second wife and any of her children will be identified as Family ID 02.
d. In the case of a widow who moves back in with her parents:
i. If she has no children, she is identified by the Family ID of her parents.
ii. If she has at least one child, she and her child are assigned a new Family ID
e. In the case of foster children: the fostered child has the same Family ID as the foster parent, regardless of blood relation.
f. In the case of visitors: Visitors will have a new Family ID.
g. In the case of a single-person household: You must still enter a family ID of 1.
