Population projections illustrate how Australia's population will change in the future as a result of certain assumptions. This dataset presents 72 scenarios, comprising combinations of different rates of fertility (x3), mortality (x2), net overseas migration (x4) and net interstate migration (x3).

This dataset contains data used in determining the ABS Population Clock. The data is annual data updated quarterly, and is based on past component data published in Australian Demographic Statistics (cat. no. 3101.0) or Department of Immigration and Border Protection (DIBP) forecasts. Population Clock components and results do not constitute official ABS projections and should not be used for purposes other than the Population Clock.

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 (based on different assumptions of future fertility, mortality and migration) of the resident population of Australia, the states and territories, capital cities and balance of states, by age and sex for the base year to 2101 (for Australia) and for the base year to 2061 (for the states and territories, capital cities and balances of states). Also includes summary measures such as percentages of population in selected age groups and median ages as well as detailed notes on the assumptions used.

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.
