Glossary

certified suicide death: Official fact of death and cause of death determination (including suicide death) from the Registrars of Births, Deaths and Marriages in each state and territory and the National Coronial Information System, compiled and coded by the Australian Bureau of Statistics.

ex-serving: ADF members in the serving or reserve population on or after 1 January 2001 and who separated from the ADF after 1 January 2001.

reserve: ADF members in the active or inactive reserve forces for the Royal Australian Navy, Australian Army or Royal Australian Air Force, on or after 1 January 2001. Most ADF members leaving full-time service are transitioned into the inactive reserve forces unless there are medical grounds preventing this.

serving full-time: ADF members serving in a regular capacity in the Royal Australian Navy, Australian Army or Royal Australian Air Force on or after 1 January 2001, on continuous full-time service, or participating in the gap year program.

standardised mortality ratio (SMR): A comparison of the suicide rates in the ADF populations with the Australian population, adjusting for differences in age structure. An SMR of 1.0 indicates similar rates in each population. An SMR greater than 1.0 indicates the ADF population has a higher rate than the Australian population, and an SMR less than 1.0 indicates the ADF population has a lower rate than the Australian population.

statistical significance: A statistical measure that provides an indication of the strength of the reported difference in suicide rates between the ADF populations and Australian population.  

suicide death rate: Number of suicide deaths occurring in 2002–2014, divided by the total population in that period. Comparative analyses adjust for differences in age structure between the ADF populations and the Australian population.
