Victoria's prison population has grown by 67 per cent since 2005, with one in three detainees behind bars without conviction, a report reveals.
Analysis by the Sentencing Advisory Council of the state's prison numbers found the jump in prisoners is largely due to an increase in people being refused bail, particularly for violent offences.
The Council's Victoria's Prison Population 2005 to 2016 report also found the types of offences people were typically going to jail for had changed.
In 2004-05, property offences were the most common crimes attracting a stint in jail.
In 2014-15, more offenders were imprisoned for offences against another person.
