The most serious offence category is assigned to a detainee based on the most serious charge laid against them during their most current period of detention. Charges are assigned to each DUMA detainee according to the Australian Bureau of Statistics' Australian and New Zealand Standard Offence Classification (ANZSOC) (ABS 2011). The category assigned to a detainee is based on a hierarchy from most to least serious offence i.e. violent, property, drug, DUI, traffic, disorder, breach, and other lesser offences respectively. For example, if a detainee was charged with a violent and a drug offence, they would be classified in the most serious offence of violent.
