NAIP Bulletin 15 shows trends in estimated alcohol-attributable assaults in Australia from 2003-04 to 2012-13. Rates of estimated alcohol-attributable assaults were calculated by applying the alcohol aetiologic fraction (AAF) method to hospital morbidity data. Nationally, the trend showed a slight decline in alcohol-attributable assaults over the 9-year period. Rates of male alcohol-attributable assaults were higher than female rates across all jurisdictions except the NT. The rates for males aged 20-29 were highest in most years across the jurisdictions.
