The difference in the rate of suicide by firearms was offset by a 1.5 fold higher rate of suicide by other means in the Vancouver area. Restricting access to handguns may be associated with a decreased rate of suicide for certain segments of the population. The two cities were similar in size, geography, unemployment rates, education and income. It was not possible to adjust for some important confounders such as illegal drug-related activity, illicit gun sales, and SES of the victims. The study also has the limitations of all ecological studies.
Strict regulations govern the purchase, ownership, and carrying of firearms in Vancouver.
Concealed weapons are not permitted in Vancouver, a restricted weapons permit is required for handgun purchase, and self defense is not a valid reason for handgun purchase. Seattle allows legal purchase of handguns for self-defense and concealed weapon permits are easily obtainable. Firearm homicide rate was 5 fold higher in Seattle. Robbery , burglary and non-gun homicide rates were equal. Restricting access to handguns may reduce homicide rate in a community.
