​For the record: Impact of the lockouts on the CBD

Release date: Thursday 20 June 2019

A study by researchers at the University of Sydney reported in the Sydney Morning Herald today claims that the Sydney lock-out laws made no impact on non-domestic assaults in the Sydney CBD. 

This claim conflicts with research findings published by the Bureau of Crime Statistics and Research (BOCSAR) which have found a significant reduction in non-domestic assaults in the Sydney CBD attributable to the lockouts (the most recent finding showing a 13% decline*). 

There are various differences between these studies that may account for these results.  The Sydney University researchers have used a different statistical method, different geographical regions and a different time period than the BOCSAR studies. 

We have asked the researchers at Sydney University to re-analyse their data using the time periods and areas included in the study by the Bureau of Crime Statistics and Research.

* In July 2019 BOCSAR re-ran our 2017 analysis, addressing concerns raised by the University of Sydney.  In the alternative analysis we still found a reduction in non-domestic assault in the Sydney CBD but the estimated size of the reduction was 8.1% (compared with 12.6% in the original paper.
