The National Mortality Database (NMD) holds records for deaths in Australia from 1964 to 2014 and is considered an Essential Statistical Asset for Australia. The database comprises information about causes of death and other characteristics of the person, such as sex, age at death, area of usual residence and Indigenous status. The cause of death data are sourced from the Registrars of Births, Deaths and Marriages in each state and territory, the National Coronial Information System and compiled and coded by the Australian Bureau of Statistics (ABS).
