Residential buildings are the buildings which by initial building or after reconstruction are suitable for living by one or several households. In the coverage of the survey are included inhabited and uninhabited residential buildings, cook-houses (as separate buildings), hostels, boarding-houses, cloisters and the homes for eldery people in which live joint households.
Steel-concrete buildings are those of which the carrier and the floor constructions are built of steel-concrete and the walls are made of panels, brick masonry or other materials.
Solid structures are those of which the carrier walls are of brick and stone masonry and the belts, the beams and the floor construction are made of steel-concrete but have no steel-concrete columns. The buildings of which the floor elements are precast reinforced concrete units also refers to the solid structures.
In the group of "other buildings" are included the structures that are built of stones, sun-dried brick, wood and other materials.
The dwelling is separate and independent in the terms of construction place, which by initial building or after reconstruction is suitable for living, has one or several rooms (housing or service) and has one or several separate exits to a generally accessible part (stairs, yard or straight to the street), irrespective of whether a kitchen has been built.
A dwelling is also every single dwelling (a room), which is not connected with other rooms, has a separate exit to a generally accessible part (stairs, yard or straight to the street), and is used as a kitchen and a place for living or only for living.
The number of dwellings includes inhabited and uninhabited dwellings suitable for living: hostels, boarding-houses, cloisters and the homes for eldery people in which live joint households: cook-houses when they are separate buildings, dwellings in nonresidential buildings (administrative, farm buildings and others such as schools, hospitals, hotels and barracks) in which constantly live households.
A dwelling which is situated on two or three floors in one residential building where live one household is counted as one dwelling. However, each floor is counted as a separate dwelling if separate household lives on each floor.
The rooms in the hotel type constructions (hall system) in which live separate households are counted as separate dwellings. All rooms and services in the buildings in which are accommodated people from the joint household (boarding-houses, specialized homes, cloisters, prisons, etc) form one dwelling place.
The halls with direct lightening without the vestibules, the kitchens and the rooms with area less than 4 square metres are counted as rooms by arranging the dwellings in groups according to the number of rooms.
If there are two kitchens or a cook-house in the dwelling the second kitchen or the cook-house is counted to the number of rooms.

The useful area of the dwelling is sum of the living-floor-space and service floor space. Until the end of 2018 the useful area is sum of living-floor space, kitchen area and service floor space.
