The Housing census as part of the Register-based census and the Register-based labour market statistics records the entire building and dwelling stock in Austria. The complete survey is conducted by using information from administrative registers as per 31 October (from 2021 on every year). The Buildings and dwelling register is the basic register for the Housing census.
Buildings are independent structures containing one or more dwellings or other spaces which are covered by a roof and enclosed within external walls (in the case of free-standing construction) or dividing walls (in the case of closed construction) that extend from the foundations to the roof, and which are designed for residential or other commercial purposes.
The data recorded on the stock of buildings includes building characteristics, type of ownership, construction period, number of dwellings and net floor area.
