ABOUT THIS RELEASE
This publication is part of the Demography Working Paper series.
Estimates of the number of resident households are produced quarterly by the ABS. The estimates are based on the household population series (that is, the estimated resident population (ERP) that usually lives in private dwellings), to which propensities to form households are applied. While national household estimates have been reliable, the data have been volatile at the state, part of state, and household composition levels. Household composition refers to the combinations of persons aged 0 to 14 with persons aged 15 or more. In response to requests to improve this series, the ABS has improved the method of household estimation. This paper examines the underlying data problems, and demonstrates how the new series is an improvement on the previous method.
