BACKCAST ESTIMATES FOR THE PERIOD 2006 to 2015

Backcast estimates included in this release are compiled using the 30 June 2016 estimates of the Aboriginal and Torres Strait Islander population as the base population and assumptions on mortality and interstate migration.

A single time series of Aboriginal and Torres Strait islander population estimates for the period 2006 to 2015 has been produced using the following assumptions:

  • 2011-2016: life expectancy at birth increases by 0.40 years per year for males and 0.25 years per year for females
  • 2006-2011: life expectancy at birth increases by 0.30 years per year for males and 0.20 years per year for females
  • Net interstate migration assumptions for each of the two intercensal periods will be based on levels observed in each respective intercensal period
  • Zero net overseas migration occurred across the entire series with no arrivals and departures.


There were 798,400 Aboriginal and Torres Strait Islander people in 2016 based on the 2016 Census. Backcast estimates of the Aboriginal and Torres Strait Islander population was 640,000 in 2006. Between 2006 and 2016, the Aboriginal and Torres Strait Islander population increased by 2.2% per year on average.
