Using population-based data on alcohol consumption and related harms to estimate the relative need for alcohol services in Victoria, Australia

The relative need for alcohol services across different geographic areas of Victoria was examined through an analysis of population-based datasets on alcohol consumption and related harms, and socio-demographic variables available in Victoria. A Factor Analysis was undertaken using the Local Government Area (LGA) as the unit of analysis, which revealed three factors that explained 76% of the variance in the dataset. One factor identified in the analysis was taken as an indicator of variation in the need for alcohol services as all of the alcohol-related variables loaded strongly on this factor. The distribution of ranks for factor scores (determined through regression) obtained for this ‘alcoholness’ factor across LGAs in the state showed that scores were highest in non-metropolitan areas as well as inner-suburban Melbourne. The results are discussed in terms of their practical implications for resource allocation and program funding procedures and the potential for the indicator as a tool for monitoring alcohol-related harm in the community.
