Western Australia Tomorrow population forecasts

Medium and long term population and household forecasts.

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.  

Please note: See Excel spreadsheets for more details.
