Grouping youth offenders by their offending patterns

The Crime Statistics Agency (CSA) has today released its sixth ‘in brief’ research paper titled Patterns of recorded offending behaviour amongst young Victorian offenders. This new research continues a program of work exploring youth crime.

The research identifies groups of offenders based on their distinct patterns of offending behaviour between the ages of 10 and 17. Four groups were identified based on their age at first offence and how often they offended (low, adolescent-limited, late developing and high). The vast majority (89%) of offenders fell into the low frequency group, who had an average of just 0.4 offences recorded per year at the peak of their offending.

CSA Chief Statistician Fiona Dowsley said that while most offenders were classified as ‘Low’ offenders, those that were classified in the other groups were responsible for a much larger proportion of criminal incidents.

“While only 1.6% of young offenders belong to the ‘High’ frequency group, these offenders were responsible for over a fifth of all criminal incidents perpetrated by this sample of young offenders.”

The high group included offenders whose offending steadily increased from a young age before declining between the ages of 15 and 17, and offending amongst the late developing group started at a low frequency before increasing rapidly from the age of 15.

The research also found that certain risk factors were identified for a higher likelihood of inclusion in one of the higher rate groups. “Offenders who were male, who identified as Aboriginal or Torres Strait Islander, and who were living in one of the most disadvantaged areas were more likely to be classified in a high frequency offending group. This is in line with similar studies in other Australian jurisdictions.”
