The study also found that a sharp increase in domestic violence and packaged liquor licenses but the relationship was weaker and the threshold was lower (0.75 per 1,000 residents).
The research, which is being presented at the Applied Research in Crime and Justice Conference in Darling Harbour later today, examined the relationship between liquor outlet density and violence across NSW LGAs.
Separate analyses were undertaken for different types of liquor licence. The analysis also controlled for other factors in an area (e.g. the percentage of young men aged 15-34) that might influence levels of violence.
Unlike the situation for hotels and packaged liquor licenses, the relationship between violence and the density of clubs and on-premises licences was linear; meaning that regardless of the concentration level, domestic assault rates increase as the density of club or on-premises licences increases in an area.
A 10 per cent increase from the mean club concentrations, for example, would produce a 1.3 per cent increase in the rate of DV assaults.
The relationship between liquor outlet density and violence was just as strong for non-domestic assault as it was for domestic assault.
As with domestic assault, recorded rates of non-domestic assault increased markedly when the density of hotels exceeded 2.0 per 1,000 residents or when the packaged liquor concentration level exceeds 0.75 per 1,000 residents.
Commenting on the findings, the Director of the Bureau, Dr Don Weatherburn, said that the study added weight to previous studies showing that the relationship between liquor outlet density and violence was complex.
"The critical relationship appears to be that between hotels and violence but the relationship is not straightforward. Up to a density of two hotels per 1,000 residents, the increase in violence is modest. Beyond that point, it seems to increase rapidly."
