Indicator technical specifications
The information below provides technical specifications for the summary indicator data presented in the quick reference guide.
National Framework Indicator 0.5 Child Homicide: Assault (homicide) death rate for children aged 0–17 years
||Number of deaths of children aged 0–17 years from assault in the reference period
||Australian Institute of Criminology National Homicide Monitoring Program (NHMP)
||Number of children aged 0–17 years at 31 December
||AIHW Population Database (sourced from ABS Australian Demographic Statistics)
There are two key sources of data for the NHMP: offence records derived from each state/territory police service, supplemented where necessary with information provided directly by investigating police officers and/or associated staff; and state coronial records such as toxicology and post-mortem reports.
The term homicide refers to a person killed (unlawfully). Homicide is defined by the criminal law of each state and territory, and varying definitions exist between jurisdictions in terms of its degree, culpability and intent.
The definition of homicide in the NHMP reflects the operational definition used by police throughout Australia. Excluded from this definition are attempted murder and violent deaths, such as industrial accidents involving criminal negligence (unless a charge of manslaughter is laid). Lawful homicide, including that by police in the course of their duties, is also excluded.
Due to the small number of homicide deaths, reported data are aggregated for a two-year period.
The COVID-19 pandemic and the resulting Australian Government closure of the international border from 20 March 2020, caused significant disruptions to the usual Australian population trends. This report uses Australian Estimated Resident Population (ERP) estimates that reflect these disruptions.
Accordingly, in the year July 2020 to June 2021, the overall population growth was much smaller than the years prior and in particular, there was a relatively large decline in the population of Victoria. ABS reporting indicates these were primarily due to net-negative international migration (National, state and territory population, June 2021 | Australian Bureau of Statistics (abs.gov.au)).
Please be aware that this change in the usual population trends may complicate your interpretation of statistics calculated from these ERPs. For example, rates and proportions may be greater than in previous years due to decreases in the denominator (population size) of some sub-populations.
