Question 3P. Material of outer walls
Answers to this question are to be completed based on form 1-?? (characteristics of dwellings), excluding those households living in private housing stock where the questions are to be completed through interviewing.
One of codes is to be marked, which corresponds to the item wanted.
If a house is made of bricks, natural or artificial stone, the item "bricks, stone" is to be marked.
If a house is made of concrete or reinforced concrete blocks and panels, slag blocks or its walls are filled with slag, the item "concrete, reinforced concrete, blocks, panels" is to be marked.
If the walls of a house are made of wood (blocks or logs) or of prefabricated wood boards, the item "wood" is to be marked.
"Wood" is also to be marked if a wooden house is coated with bricks.
If the first floor (half or part of a house) is made of bricks or stone, but the second floor (half or part of a house) is wooden, the item "mixed material" is to be marked.
If the walls of a house are made of adobe blocks, prefabricated panels, etc (those coated with bricks inclusive), or of any other materials not mentioned above, the item "other material" is to be marked.
When the walls of a house are made of several different materials, they are to be related to the prevailing group of materials used in the construction.
