Part of the mythology of anti-gun activism is that fewer guns mean less violence. But in at least one measure of violence, homicide, there seems to be no correlation between the number of guns per capita and the number of homicides per capita.
This infographic reveals the fallacy of this claim. The United States has the most guns per person, but is among the lowest homicide nations. Many other countries have low gun ownership, but very high homicide rates, and some countries, notably the U.K. and Australia have low gun ownership and low homicide rates.
In short, there is no correlation between guns and homicide.
