The relationship between alcohol and crimes including domestic abuse and violence, underage drinking, robbery, assault and sexual assault is clearly documented.
FACT: 5.3 million adults − 36% of those under correctional supervision at the time − were drinking at the time of their conviction offense
Excessive drinking leads to criminal behavior:
The US Department of Justice (DOJ) estimated that a majority of criminal offenders were under the influence of alcohol alone when they committed their crimes.
Federal research shows that for the 40% of convicted murderers being held in either jail or State prison, alcohol use was a factor in the homicide.
FACT: Alcohol is a factor in 40% of all violent crimes today
About 3 million violent crimes occur each year in which victims perceive the offender to have been drinking. Crimes include: rape, sexual assault, robbery, aggravated and simple assault. About two-thirds of violent crimes are characterized as simple assaults.
Based on victim reports, alcohol use by the offender was a factor in:
37% of rapes and sexual assaults
15% of robberies
27% of aggravated assaults, and
25% of simple assaults
Statistics showing correlation between alcohol and crime (from the NCADD Fact Sheet Alcohol and Crime):
Among violent crimes, the offender is far more likely to have been drinking than under the influence of other drugs, with the exception of robberies, where other drugs are likely to have been used such as alcohol.
Alcohol is more likely to be 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.
1.4 million incidents of alcohol-related violence are committed against strangers.
Individuals under age 21 were the victims in just over 13% of incidents of alcohol-related violence, and the offenders in nearly 9%.
70% of alcohol-related incidents of violence occur in the home with greatest frequency at 11:00 pm
..20% of these incidents involve the use of a weapon other than hands, fists or feet.
