How do U.S. gun ownership or gun crime compare with those in other nations? Although international data collection suffers from the same problems as gathering information about guns in the U.S., most research agrees that civilians in the United States own more firearms both total and per capita than those in any other nation.
The Small Arms Survey in 2007 found not only that U.S. civilians had more total firearms than any other nation (270 million) but also that the rate of ownership (about 90 firearms for every 100 people) was higher than in other countries. “With less than 5 percent of the world’s population, the United States is home to 35-50 per cent of the world’s civilian-owned guns,” according to the survey, which included estimates for 178 countries.
As for gun crime, research has found that the U.S. has a higher gun homicide and overall homicide rate than most developed nations, although the U.S. does not have the world’s highest rate for either. The U.S. does not outrank other developed nations for overall crime, but crimes with firearms are more likely to occur in the U.S. (
Van Dijk, et al., 2007).
The United Nations Global Study on Homicide (
UNODC, 2011) estimated that 199,000 homicides, or 42% of the 468,000 worldwide total in 2010, were committed by firearm.
According to U.N. statistics, the U.S. firearm homicide rate and overall homicide rate are higher than those in Canada and in Western European and Scandinavian nations, but lower than those in many Caribbean and Latin American countries for which data are available.
Where does the U.S. rank internationally in terms of gun crime of all types? A report that compared 2003-2004 victimization survey data for 30 countries, including most developed nations, found that the U.S. ranked about average in an overall index of common crimes (
Van Dijk et al., 2007).
However, the report placed the U.S. among the top countries for attacks involving firearms. “Mexico, the USA and Northern Ireland stand out with the highest percentages gun-related attacks (16%, 6% and 6% respectively).” The U.S. had the highest share of sexual assault involving guns.
