Projections of households and household populations by household size propensities

Abstract

This paper describes a method for constructing projections of numbers of households of various types and the numbers of people in that structure. The method uses the concept ofhousehold size propensity, that is the probability that a person of given age and sex resides in a household of sizea, c, wherea is the number of adults per household andc is number of children per household. Using data from the 1981 and 1986 Censuses and population projections to the year 2011, the method produces projections of Australian households and household populations by size of household for five-year intervals from 1991 to 2011.
