Norway - Dwelling Stocks

The number of dwellings started, under construction, and completed; and their aggregate floor space. Monthly from 1992. Figures are in terms of number of buildings.

Definitions

• Starts: Since 2000, the date when starting permission is given, else when the foundation is begun.
• Completions: When the building is physically ready to be put to use, or when at least 50% of its utility floor space is in use.
• Gross floor space: Includes the outside of the outer walls. Used for non-dwellings before 1983.
• Useful floor space: Used before 1983. Less than utility floor space.
• Utility floor space: The floor area measured within the outer walls, as defined by NS 3940 "Area and Volume Calculations of Buildings."
• Dwelling unit: Conventional dwellings with at least one room and kitchen, and which are used year-round.
• Dwelling stock: The number of dwelling units; there may be multiple units within a single building.
• Single room: Living quarters without kitchen, but with separate access, water and toilet.
• Dwellings: The sum of dwelling units and single rooms.

Compilation

Statistics Norway performs a complete census of buildings at three levels (national, county and municipal) and three frequencies (annually, quarterly, and monthly). It is based on the Ground Parcel, Address and Building Register (GAB), a computer database in effect from late 1982.

Building stock includes all main buildings (not extensions) measuring larger than 15 m² which have not been reported as destroyed. A single building may contain multiple dwelling units.

The type of building is established according to function. Combined buildings are classified by the function occupying the main part of the utility floor space. Figures describing construction of dwellings include both dedicated residential buildings and mixed-used nonresidential buildings.

Stage of construction data (including utility floor space) is subject to revisions in part because of delays or mistakes in registering projects with GAB. However, such revisions are uncommon.
