Interviewer instructions
Question 6, 7 and 8: The type of construction materials used for the roof, walls and floor is asked in these questions. If more than one type of material is used for any of these, the material used for the majority of the area of the roof, walls, and floor is the one to be recorded. For multi-story buildings, the roof is the top-most cover of the highest story of the building (outside), whereas walls and floor are those found in the census unit where the living quarters of the household is located.
The roof is the top-most cover of a building, so that the people living under the roof will be sheltered from sun, rain, etc.
Look at the walls of the respondent's living quarters. A wall is the outside boundary/divider with another building or the exterior of the building. The interior walls which divide the living quarters into rooms are not considered.
