25. What is the relation or relationship of [the respondent] with the head of the household?
The relation or relationship by blood or affinity of the interviewed person is established in relation to the head of the household (Person 01).
Head of the household
It is a person recognized by the rest of the members of the household. It is generally a father or mother or the principal economic support of the household.
[Below the text is a form.]
[p. 165]
If persons who form a census household do not recognize anyone as head (for example groups of students or workers who form a common household), choose any of them, who is older than 18 years, as head of the household.
The alternative "son, daughter" (option 3) includes also members of the household who are adoptive children or children of other conjugal unions.
