Guns Across State Lines


New Jersey has some of the most restrictive firearm laws in the country. Unfortunately for New Jersey most of the other 49 states aren't so fussy about selling guns. That might be why 79% of guns in New Jersey recovered and traced by the Bureau of Alcohol, Tobacco, Firearms and Explosives were bought out of state.

Axios has mapped the ATF's Firearms Trace Data - 2016 to show the top ten out of state sources for firearms for each U.S. state. The interactive flow map in How guns move across state lines visualizes the top ten out of state sources for recovered and traced guns in each state. If you hover over a state you can see how many guns were traced by the ATF in that state in 2016. You can also see the percentage which were originally purchased out of state and the ten states where the most guns were originally purchased.

If you want to make your own interactive flow map then you might be interested in Sarah Bellum's Canvas Flowmap Layer for ArcGIS or the Leaflet.Canvas-Flowmap-Layer.
