ESTIMATES
Summary of assumptions
A single time series of Aboriginal and Torres Strait Islander estimates for the period 1996 to 2010 has been produced. The assumptions used are summarised below:
- Aboriginal and Torres Strait Islander life expectancy at birth increases by 0.3 years per year for males and 0.15 years per year for females between 2006 and 2011 and increases by 0.2 years per year for males and 0.15 years per year females between 1996 and 2006. This assumes Aboriginal and Torres Strait Islander life expectancy at birth of 65.5 years for males and 71.4 years for females for Australia in 1996;
- net interstate migration for each of the three intercensal periods will be based on levels observed in each respective intercensal period; and,
- zero net overseas migration occurred across the entire series with no arrivals and departures.
