A building may include one or many dwellings. The building characteristics are only indicated for the first dwelling. Thus if a building is comprised of 4 dwellings, fill in the 'principal building material of walls' and 'principal building material of roofs' headings for dwelling number 1 only; i.e. the household whose visitation order in the building is 01. Do not write any information for dwelling 2, 3 or 4, i.e. for households whose visitation order in the household is 02, 03 or 04.

2. Main Construction Material of the Roofs.

a) Concrete: Put into this category any building whose roof covering is made of at least two-thirds reinforced concrete or any other combination of 'cement blocks'.

b) Tiles: Put into this category any building with at least two-thirds of the roof in terra cotta tiles, commonly called 'tiles'.

c) Sheet Metal: Put into this category any building with at least two-thirds of the roof in iron or laminated sheets of iron.

d) Wood: Put into this category all buildings whose roof is at least two-thirds construction wood.

e) Thatch: Put into this category any building whose roof is made of at least two-thirds thatch. These houses are generally known in Haiti as caille paille.

f) Other: Put all buildings which do not correspond to any of the above categories for at least two-thirds of their roof covering in the 'Other' category.
