Multiple mass shootings have occurred in just the past two days — at a courthouse in Masontown, Pennsylvania; a business in Middleton, Wisconsin; and a Rite Aid distribution center in Aberdeen, Maryland.
This is, apparently, not abnormal for 2018. According to the Gun Violence Archive, there have been nearly as many mass shootings so far this year as there have been days.
“There have been 262 American mass shootings (4+ shot or killed in the same incident, not including the shooter) in the 263 days of 2018,” the Gun Violence Archive tweeted.
This is roughly in line with what we’ve seen in recent years. In all of 2015, there were 335 mass shootings. In 2016, there were 382. In 2017, there were 346.
In total, there have been more than 1,800 mass shootings in the US since 2013. Here’s the full map of mass shootings going back to 2013:
As the tweet noted, the Gun Violence Archive defines mass shootings as events in which four or more people, excluding the shooter, were shot but not necessarily killed in a similar time and place.
This is different than other definitions of mass shootings. Some definitions consider an event a mass shooting only if four or more people were killed. Others, like Mother Jones’s tracker, exclude certain types of shootings, such as gang and domestic violence, even if there were mass casualties.
Regardless of whether Gun Violence Archive’s count fits everyone’s definition of a mass shooting, the point is the same: The US regularly — almost daily — has shootings in which multiple people are wounded or killed.
America has a lot of gun violence
Beyond mass shootings, the US has a lot of gun violence, including homicides, suicides, and accidental events. A study published in JAMA found that the US is one of six countries that make up half of gun deaths worldwide; the other countries were Brazil, Mexico, Colombia, Venezuela, and Guatemala.
The US had a rate of 10.6 gun deaths per 100,000 people in 2016, which dwarfed comparable developed countries: Switzerland’s rate was 2.8, Canada’s was 2.1, Australia’s was 1, Germany’s was 0.9, the United Kingdom’s was 0.3, and Japan’s was 0.2.
The good news is that crime and murder have generally trended down over the past couple decades in the US. The bad news is that the US, based on the numbers from the JAMA study, continues to see far more gun deaths than other developed nations.
That’s not because America is completely helpless in the face of these tragedies. The reason other developed nations have less gun violence in general is because they have stricter gun laws and fewer guns. (For reference, the US had 120.5 guns per 100 people in 2017 — more guns than people — while Canada had 34.7 per 100 people, Germany had 19.6 per 100 people, and Australia had 14.5 per 100 people, according to the Small Arms Survey.)
Good research backs up the link between more gun control and fewer gun deaths. A 2016 review of 130 studies in 10 countries, published in Epidemiologic Reviews, found that new legal restrictions on owning and purchasing guns tended to be followed by a drop in gun violence — a strong indicator that restricting access to firearms can save lives. The review suggested that no one policy seems to have a big effect by itself, but a collection of gun restrictions can produce a significant effect over time.
Similarly, a recent review of US studies by the RAND Corporation found some evidence that stricter gun laws, like background checks, reduce gun deaths and injuries, while permissive gun laws, like concealed carry, increase gun deaths and injuries.
But in a political and cultural environment that’s made it difficult to pass almost any new gun control law at the federal level, Americans have by and large just gotten used to the regular pace of tragedies. As Sheriff Donny Youngblood of Kern County, California, said at a press conference after a mass shooting in Bakersfield, California, last week, “This is the new normal.”
