B3 Construction materials of the outer walls
Cross out the circle applicable to the kind of materials used in the construction of the outer walls. Fill up this item only through observation but if in doubt, ask the respondent for the material mainly used for the outer walls.
The kinds of construction materials of the walls are as follows:
For a house or building in which half of the stories are walled with concrete/brick7stone and the other half, with wood, marked the circle opposite the category Half concrete/brick/stone and half wood. Mark also this category wherein the walls are made of about half of each of the two groups of materials.
For a two-storey house especially in rural areas wherein the ground floor is used for poultry, storage of grains, farm implements, etc., report the material used in walling the second floor, unless the walls can be classified under Half concrete/brick/stone and half wood. In other cases where in the walls are made of different materials, report the material dominantly used.
Housing units in non-building structures such as culverts, bridges, etc. should have a marked circle of category Makeshift/Salvaged/Improvised Materials.
Cross out the circle of category "others" and specify the kind of material used for the outer walls if it is not one of those mentioned above.
This variable indicates the construction materials of the outer wall.
