Part D: Dwelling Unit Characteristics and Access to Facilities

Structure: A structure is a defined as "any unit of construction that has four walls or an all-round wall, a roof and at least one door irrespective of the type of construction materials used". Buildings, caravans, tents, and tinned houses are some examples of structures. Based on the materials used for construction of walls and roof, the structures in this Census are classified into three major groups: permanent, semi- permanent and traditional.
i.) Permanent structure:
A permanent structure is one having a roof made of iron sheets, tiles, concrete or asbestos, and walls made of burnt bricks, concrete or stones. Examples include a house made of stone walls and corrugated iron sheets, a shop with burnt bricks and concrete roof, a house with concrete walls and asbestos roofing, caravans and tinned houses.
Note: A structure with stone walls, burnt bricks or concrete with a corrugated iron roof which is covered with tiles should be taken as permanent (the titles should be considered as finishing or decoration).
ii.) Semi-permanent structure:
A semi-permanent structure is one lacking the construction materials of a permanent structure for wall and roof. This category includes, for example, structures which have iron sheet roofing and sun-dried bricks or burnt bricks walls with a thatched roof. It also includes tents.
iii.) Traditional structure:
A traditional structure is one having a thatched roof with mud walls, or walls made of mud and wattle.
D2. Type of structure: Ask the respondent for the materials used for construction of the structure and enter the appropriate code in column D2.
