* A 1993 nationwide survey of 4,977 households found that over the previous five years, at least 0.5% of households had members who had used a gun for defense during a situation in which they thought someone "almost certainly would have been killed" if they "had not used a gun for protection." Applied to the U.S. population, this amounts to 162,000 such incidents per year. This figure excludes all "military service, police work, or work as a security guard."[12]
Based on survey data from a 2000 study published in the Journal of Quantitative Criminology,[17] U.S. civilians use guns to defend themselves and others from crime at least 989,883 times per year.[18]
* A 1993 nationwide survey of 4,977 households found that over the previous five years, at least 3.5% of households had members who had used a gun "for self-protection or for the protection of property at home, work, or elsewhere." Applied to the U.S. population, this amounts to 1,029,615 such incidents per year. This figure excludes all "military service, police work, or work as a security guard."[19]
* A 1994 survey conducted by the U.S. Centers for Disease Control and Prevention found that Americans use guns to frighten away intruders who are breaking into their homes about 498,000 times per year.[20]
* A 1982 survey of male felons in 11 state prisons dispersed across the U.S. found:[21]
• 34% had been "scared off, shot at, wounded, or captured by an armed victim"
• 40% had decided not to commit a crime because they "knew or believed that the victim was carrying a gun"
• 69% personally knew other criminals who had been "scared off, shot at, wounded, or captured by an armed victim"[22]
* "In homes with guns, the homicide of a household member is almost 3 times more likely to occur than in homes without guns."[12] [13]
* Reasons for elimination: This statistic is based on a three-county study comparing households in which a homicide occurred to demographically similar households in which a homicide did not occur. After controlling for several variables, the study found that gun ownership was associated with a 2.7 times increase in the odds of homicide.[14] This study does not meet Just Facts' Standards of Credibilitybecause:
1) The study blurs cause and effect. As explained in a comprehensive analysis of firearm research conducted by the National Research Council, gun control studies such as this (known as "case-control" studies) "fail to address the primary inferential problems that arise because ownership is not a random decision. ... Homicide victims may possess firearms precisely because they are likely to be victimized."[15]
2) The study's results are highly sensitive to uncertainties in the underlying data. For example, minor variations in firearm ownership rates (which are determined by interview and are thus dependent upon interviewees' honesty) can negate the results.[16] [17]
3) The results are arrived at by subjecting the raw data to statistical analyses instead of letting the data speak for itself. (For reference, the raw data of this study shows that households in which a homicide occurred had a firearm ownership rate of 45% as compared to 36% for non-homicide households. Also, households in which a homicide occurred were twice as likely have a household member who was previously arrested (53% vs. 23%), five times more likely to have a household member who used illicit drugs (31% vs. 6%), and five times more likely to have a household member who was previously hit or hurt during a fight in the home (32% vs. 6%).[18])
