Population projections illustrate how Australia's population will change in the future as a result of certain assumptions. This dataset presents 24 scenarios, comprising combinations of different rates of fertility (x3), mortality (x2) and net overseas migration (x4).

The estimated resident population (ERP) is the official measure of the Australian population. This dataset contains annual ERP by country of birth, age and sex at the Australia level. At the state/territory level it is available for Census years only.

Contains projections of the number of households, families and living arrangement types for 2011-2036. The projections are not intended as predictions or forecasts, but are illustrations of growth and change in the population that would occur if the assumptions about future living arrangements of Australia's population were to prevail over the projection period. Three assumption series are referred to, which are informed by data from the past four Censuses - series I (no change in living arrangement propensity), series II (historical trend gradually plateauing) and series III (historical trend continuing). These projections are not forecasts or predictions. Non-demographic factors such as economic conditions may affect future household and family formation, but have not been explicitly taken into account in these projections.
