The aim of this project is to describe and measure the adverse effects of drinking in Australia on people other than the drinker. Included in the study will be the effects of drinking on the health of others, on injuries and damage from assaults and from traffic crashes, on family life and functioning, and on the welfare of others. While the primary focus will be on estimating the magnitude of effects in their own terms, methods for costing the effects will also be considered and explored. The project will avoid duplicating existing and current analyses, and does not aim to be exhaustive. Rather, the aim is to use existing and new datasets to substantially push forward our understanding and measurement of the adverse effects of drinking in Australia on others.
