The study concluded that both the United States and Yemen were distinct from the other countries surveyed in viewing firearm ownership as a basic right of civilians and in having more permissive regimes of civilian gun ownership.At the international and regional level, diplomatic attention has tended to focus on the cross-border illegal trade in small arms as an area of particular concern rather than the regulation of civilian-held firearms.In particular, a number of quantitative studies tend towards demonstrating a firearm prevalence-homicide association." In 1983, a cross-sectional study of all 50 U. states found that the six states with the strictest gun laws (according to the National Rifle Association) had suicide rates that were approximately 3/100,000 people lower than in other states, and that these states' suicide rates were 4/100,000 people lower than those of states with the least restrictive gun laws. and the District of Columbia, and found that no gun laws were associated with reductions in firearm homicide or suicide, but that a "shall-issue" concealed carry law may be associated with increased firearm homicide rates.A 2003 study published in the American Journal of Preventive Medicine looked at the restrictiveness of gun laws and suicide rates in men and women in all 50 U. states and found that states whose gun laws were more restrictive had lower suicide rates among both sexes. A 2016 study published in The Lancet found that of 25 laws studied, and in the time period examined (2008–2010), nine were associated with reduced firearm mortality (including both homicide and suicide), nine were associated with increased mortality, and seven had an inconclusive association.According to a 2004 study, after this law was passed, firearm-related suicides and homicides, as well as the percentage of suicides involving firearms, declined significantly in that country.In 1992, Canada promulgated the Canadian Firearms Act, which aimed at ensuring that guns were stored safely.A 2004 study in the Journal of the American Medical Association found evidence that child access prevention laws were "associated with a modest reduction in suicide rates among youth aged 14 to 17 years." A 1991 study looked at Washington, D.C.'s Firearms Control Regulations Act of 1975, which banned its residents from owning all guns except certain shotguns and sporting rifles, which were also required to be unloaded, disassembled, or stored with a trigger lock in their owners' homes.
A 1990 study compared suicide rates in the Vancouver, British Columbia, Canada metropolitan area (where gun control laws were more restrictive) with those in the Seattle, Washington area in the United States.The three laws most strongly associated with reduced firearm mortality were laws requiring universal background checks, background checks for ammunition sales, and identification for guns.In an accompanying commentary, David Hemenway noted that this study had multiple limitations, such as not controlling for all factors that may influence gun-related deaths aside from gun control laws, and the use of 29 explanatory variables in the analysis.In July 1997, ECOSOC issued a resolution that underlined the responsibility of UN member states to competently regulate civilian ownership of small arms and which urged them to ensure that their regulatory frameworks encompassed the following aspects: firearm safety and storage; penalties for the unlawful possession and misuse of firearms; a licensing system to prevent undesirable persons from owning firearms; exemption from criminal liability to promote the surrender by citizens of illegal, unsafe or unwanted guns; and, a record-keeping system to track civilian firearms.This study was meant to initiate the establishment of a database on civilian firearm regulations which would be run by the Centre for International Crime Prevention, located in Vienna.
