DEFINITION OF A HOUSEHOLD
A household is a group of people who sleep in the same dwelling and share meals. These people may or may not be related by blood, but make common provision for food or other essentials for living and they have
only one person whom they all regard as the head of the household. A household may consist of one member, a couple or several couples with or without children.
All persons that have been away from the household for more than six months are not considered to be household members EXCEPT:
1) the person who is identified as head of the household even if he/she has not been with the household for nine months or more; 2) a newly born child; 3) students and seasonal workers who have not been living in or
as part of another household.

Module B - Household Composition
Respondent should be the head of the household. If the household head is not available, then ask for the second in command (most likely the wife of the household head),
