There is no clear correlation whatsoever between gun ownership rate and gun homicide rate. Not within the USA. Not regionally. Not internationally. Not among peaceful societies. Not among violent ones. Gun ownership doesn’t make us safer. It doesn’t make us less safe. A bivariate correlation simply isn’t there. It is blatantly not-there. It is so tremendously not-there that the “not-there-ness” of it alone should be a huge news story.
Gun Murder Rate is not correlated with firearm ownership rate in the United States, on a state by state basis. Firearm Homicide Rate is not correlated with guns per capita globally. It’s not correlated with guns per capita among peaceful countries, nor among violent countries, nor among European countries.
I’ve heard it stated that it isn’t fair to compare the United States to countries that aren’t as well developed and/or are poorer. I’d argue that the “unfairness” of including a multitude of countries with varying Gross Domestic and National Products demonstrates that the real issues at hand are much more complex than the simplistic view of “less guns=less crime.” One possible translation of this is, “It isn’t fair to compare the United States to countries that demonstrate that the real issue with violence is a variety of socioeconomic issues; only use those examples that fit my narrative.”
