We’ve seen a lot of maps correlating election results with other demographic or geographic data, but SurveyMonkey’s exit polling on the correlation between politics and gun ownership seems particularly stark, particularly in the context of recent events. In the 2016 U.S. presidential election, nothing predicted who you’d vote for more than whether you had a gun in the house. If only gun-owners voted, Trump would have swept 49 states; if only non-gun-owners voted, Clinton would have won at least 48.
“Over all, gun-owning households (roughly a third in America) backed Mr. Trump by 63 percent to 31 percent, while households without guns backed Mrs. Clinton, 65 percent to 30 percent, according to SurveyMonkey data,” the New York Times reported. “No other demographic characteristic created such a consistent geographic split.”
CityLab maps the geography of mass shootings in America since 1982, “both geographically and by number. ‘Mass shooting’ is defined as an incident during which four or more people are killed during a single attack in a public place, excluding the shooter. This is one of the more conservative counts—the data does not include shootings that took place during conventional crimes, like armed theft or gang violence.”
As part of an article looking at semi-automatic weapons being sold online, NPR produced the above map, which shows the locations of classified listings on Armslist (a website described as “the Craigslist of guns”) between 12 and 15 June 2016 (i.e., immediately after the Orlando nightclub shooting). About 90 percent of Armslist listings had location data; about one in four of these listings are for semi-automatic weapons. [Maps on the Web]
