In 2018, the Small Arms Survey reported that there are over one billion small arms distributed globally, of which 857 million (about 85 percent) are in civilian hands.[1][2] The survey stated that USA civilians account for an estimated 393 million (about 46 percent) of the worldwide total of civilian held firearms,[2] or about 120.5 firearms for every 100 American residents.[2]
From 1994 to 2023, gun ownership increased 28% in America. In 2023, about 16.7 million firearms were sold in the U.S. In the first four months of 2024, nearly 5.5 million firearms were sold, averaging around 1.3 million per month. About 72% of American gun owners say they own a gun primarily for protection.[3]
The world's armed forces control about 133 million (approximately 13 percent) of the global total of small arms, of which over 43 percent belong to two countries: Russia (30.3 million) and China (27.5 million).[1]Law enforcement agencies control about 23 million (about 2 percent) of the global total of small arms.[1] Gun ownership is a protected right in countries such as the United States and Yemen.[4]
Association with rates of violence in times of peace
Multiple studies show that where people have easy access to firearms, gun-related deaths tend to be more frequent, including by suicide, homicide and unintentional injuries.[7]
Gun-related death rates are positively correlated with household gun ownership rates.[8]
U.S. gun sales have risen steadily in the 21st century, peaking in 2020 during the COVID-19 pandemic.[9] "NICS" is the FBI's National Instant Background Check System.[bettersourceneeded]
Annual gun production in the U.S. has increased substantially in the 21st century, after having remained fairly level over preceding decades.[10] By 2023, a majority of U.S. states allowed adults to carry concealed guns in public.[10]
Some studies suggest that higher rates of gun ownership are associated with higher homicide rates,[11][12][13] although Gary Kleck argues that the highest-quality studies show that gun ownership does not increase homicide rates.[14] Higher rates of gun ownership are also associated with higher suicide rates[15][16] and higher accidental gun death rates.[17][18][19] The availability of illegal guns, but not that of legal guns, is associated with higher rates of violent crime.[20]
An international study by UNICRI researchers from 2001 examined the link between household gun ownership and overall homicide, overall suicide, as well as gun homicide and gun suicide rates amongst 21 countries. Significant correlations between household gun ownership and rates of gun suicides for both genders, and gun homicide rates involving female victims were found. There were no significant correlations detected for total homicide and suicide rates, as well as gun homicide rates involving male victims.[21] This study has been criticized for combining high-income countries (like the United States) with middle-income countries (like Estonia); if middle-income countries are excluded from the analysis, a strong relationship emerges between gun ownership and homicide.[22] However the Hemenway study has been criticized in response as well. When removing the United States as an outlier and using the superior proxy of gun ownership in the study (percentage of firearm suicides over all suicides), the relationship ceases to be significant. The association between gun ownership and homicide rates across nations is dependent on the inclusion of the U.S.[23] Studies in Canada that examined the levels of gun ownership by province have found no correlations with provincial overall suicide rates.[24] A 2011 study conducted looking at the effects of gun control legislation passed in Canada and the associated effects in homicide rates found no significant reductions in homicide rates as a result of legislation.[25] A case-control study conducted in New Zealand looking at household gun ownership and the risk of suicides found no significant associations.[26]
