The household projection is based on the population figures of the main scenario of the population projection for Austria and the federal provinces. The household represantative rates, which are linked to the population projection to calculate the household figures, and the shares of the population living in institutional households are derived from the most recent results of the Register-based Census / Register-based Labour Market Statistics. These rates are held constant throughout the projection period. Thus, this projection measures the purely demographic impact on the future number and structure of private households.
