Explanatory Notes

Mortality data

  1. Cause of Death Unit Record File data are provided to the AIHW by the Registries of Births, Deaths and Marriages and the National Coronial Information System (managed by the Victorian Department of Justice) and include cause of death coded by the Australian Bureau of Statistics (ABS). The data are maintained by the AIHW in the National Mortality Database.
  2. Causes of death are coded by the ABS to the International Statistical Classification of Diseases and Related Health Problems (ICD).       
  3. Deaths are counted according to year of registration of death, not necessarily the year in which the death occurred.        
  4. Deaths registered in 2015 and earlier are based on the final version of cause of death data; deaths registered in 2016 are based on revised version; deaths registered in 2017 and 2018 are based on preliminary versions. Revised and preliminary versions are subject to further revision by the ABS.
