It really doesn’t matter how you slice this data. The conclusion is inescapable: High concentrations of private, legal gun ownership do not correlate positively to increased murders. Indeed, you can look at almost any slice of data and conclude the opposite: Higher private ownership of guns can be strongly correlated to lower murder rates.
The data also exposes some myths I have heard about gun control. For example, I’ve heard activists tout Australia, which supposedly banned all guns. Australia has advanced a number of gun control measures over the years. Nevertheless, according to the data, Australia has a rate of private ownership of guns of 13,100 per 100,000 and a murder rate of .98.
Australia has almost twice as many guns per capita as the United Kingdom, for example, and a comparable murder rate. New Zealand has almost twice as many guns per capita as Australia but a lower crime rate.
