Western Australia Tomorrow is a set of forecasts1 based on trends since the 1980s. The forecasts represent the best estimate of future population size if trends in fertility, mortality and migration continue. They use the latest information about changes in trends. In some cases these have occurred since the 2006 base year.
Trend forecasts are used in a number of ways. One of them is to identify those futures which we wish to build upon and some that we would rather avoid. As a result government has adopted plans and strategies that are expected to change future trends. These include Directions 2031 and Beyond, Pilbara Cities and Supertowns. Each of the plans and strategies has included a forecast of future population.
