BACKGROUND
The purpose of this project was to update the previous cycle conducted in conjunction with the 2006 Census, which provided estimates of under-identification of Aboriginal and Torres Strait Islander deaths during the Census processing period in 2006-07. These estimates were used in the calculation of the 2006 Census-based series of life expectancy estimates for Aboriginal and Torres Strait Islander people (see Indigenous Mortality Quality Study, 2006, ABS cat. no. 4723.0, and Experimental Life Tables for Aboriginal and Torres Strait Islander Australians, 2005-07, ABS cat. no. 3302.0.55.003).
