About 415,000 crime victims used a firearm to defend themselves between 1987-1992.
In 1994 the US Department Of Justice published a data brief on "Guns and Crime"
On average in 1987-92 about 83,000 crime victims per year used a firearm to defend themselves or their property. In 1992 offenders armed with handguns committed a record 931,000 violent crimes and on average in 1987-91 there were about 667,000 crimes committed with a handgun per year.
Three-fourths of the victims who used a firearm for defense did so during a violent crime; a fourth, during a theft, household burglary, or motor vehicle theft.
Handgun crimes accounted for about 13% of all violent crimes. As measured by the National Crime Victimization Survey (NCVS), the rate of nonfatal handgun victimizations in 1992--4.5 crimes per 1,000 people age 12 or older--supplanted the record of 4.0 per 1,000 in 1982.
