The National Death Index (NDI) is a catalogue of death records that is used in data linkage for epidemiological studies. Its use is strictly confined to AIHW Ethics Committee approved health and medical research. The NDI contains person level records of all deaths occurring in Australia since 1980 obtained from the Registrars of Births, Deaths and Marriage in each state and territory.
The AIHW maintains a secure physical and computer environment for the linkage of the NDI with other datasets for research purposes, along with other measures to protect the privacy of individuals and the confidentiality of information. For more information, see the AIHW's Customer care charter.
NDI records are supplemented with cause of death information using a once-off data linkage with the NMD. This enhancement enables research that requires both fact of death (whether a person died) and cause of death (what the person died from).
The National Death Index (NDI) is a Commonwealth database that contains records of deaths registered in Australia since 1980. Data comes from Registrars of Births, Deaths and Marriages in each jurisdiction, the National Coronial Information System and the Australian Bureau of Statistics.
Address at time of death
Note: Cause of death variables are updated annually while all other variables listed above are updated monthly.
* Clerical review is the process where a person reviews the record pairs generated through the linkage (i.e. cohort records linking to NDI records) and for each record pair decides whether to accept or reject the link.
The AIHW has access to COD unit record data for deaths registered up to and including 2016. For further information on COD refer to Deaths data.
