Alcohol is often a factor in violence where the attacker and the victim know each other. Two-thirds of victims who were attacked by an intimate (including a current or former spouse, boyfriend or girlfriend) reported that alcohol had been involved, and only 31% of victimizations by strangers are alcohol-related. Nearly 500,000 incidents between intimates involve offenders who have been drinking; in addition, 118,000 incidents of family violence (excluding spouses) involve alcohol, as do 744,000 incidents among acquaintances.
