Western Australia Tomorrow population forecasts

Medium and long term population and household forecasts.

The WA Tomorrow Population Report No. 11 forecasts are now presented in Storymap incorporating PowerBI. The Storymap section is an infographic summary of the forecasts at the state level. It explains the components of population change and provides an overview of what the future population may look like. The forecast data can be explored further with interactive tables, charts and maps in the PowerBI section.

The trend-based age and sex forecasts in WA Tomorrow are undertaken every five years. While these forecasts predate COVID-19, it is currently unknown the extent that any impact may have on the forecasts. This may be evident in future WA Tomorrow reports.

WA Tomorrow Population Report No. 11 contains the latest population forecasts by age and sex, for Western Australia and its regions.  They represent the official WA State Government forecasts to 2031.  These forecasts supersede WA Tomorrow Population Report No. 10 (2015). 

WA Tomorrow is a series of population forecasts based on demographic trends.  The forecasts represent the best estimate of future population size if trends in fertility, mortality and migration continue. The forecasts refer to the 30 June in each stated year.

The WA Tomorrow trend forecasts are distinct from government strategies, frameworks and scenarios such as Perth and Peel @ 3.5 million, which are generally longer term in their outlook and seek to guide future growth to deliver desired patterns of urban form.

WA Tomorrow includes a forecast range (A to E), indicating five probable futures. A and B contain the lower forecasts, C is the median forecast and D and E represent the higher forecasts.

For the user who requires the best estimate of future population size, C should be used.
