The other day, I published this scatter-graph of 48 U.S. states to show there is no significant correlation between gun homicides and gun ownership by state. The plot relies on the recently released FBI data for 2014 (the FBI lacks data for Alabama and Florida). The state gun ownership rates come from a study published this summer by Injury Prevention.

Whether or not you include D.C. (the chart above does not, but if you do the trend line goes just slightly negative), there was no significant correlation in 2014.
