Part 2: For all Members of the Household

Question 4: Sex

113. Ask "what is the sex of [the respondent]? This must be done for each household member. Then mark "1" if male or "2" if female. It is always important to ask about the sex of a person even where this may be obvious. All persons must be classified by sex. Be sure to ask the sex of all persons who are not visible to you since there may be names that can refer to either sex.

114. Check that the sex is compatible with relationship and name; do not assign "female" to persons shown as "spouse" when the head is a female and vice-versa. Also, take particular attention to mark the sex of very young children correctly. Often you will not know whether a baby carried on its mother's back is a boy or a girl. In such cases, you must ask, do not guess. You should ensure that everybody's sex is recorded. Blanks are strictly forbidden.
