Twenty-five years has passed since the Royal Commission into Aboriginal Deaths in Custody (RCIADIC). This paper examines the trends and characteristics of Indigenous deaths in custody since 1991–92, using data obtained through the National Deaths in Custody Program (NDICP). NDICP data show Indigenous prisoners are now less likely than non-Indigenous prisoners to die in prison custody, largely due to a decrease in the death rate of Indigenous prisoners from 1999–2000 to 2005–06. Coinciding with this decrease in the death rate of Indigenous prisoners is a decrease in the hanging death rate of Indigenous prisoners. Monitoring trends and characteristics of both Indigenous and non-Indigenous deaths in custody supports the development of proactive strategies addressing this important issue.
