Chicago accounted for approximately 10 percent of mass shootings during a 17-month period in the U.S., according to data analyzed by The Daily Caller News Foundation.
The New York Times Editorial Board created a graphic depicting the total amount of mass shootings committed between June 12, 2016 (the Pulse Nightclub attack) and Oct. 1, 2017 (the Las Vegas massacre), based on data from the Gun Violence Archive.
The Gun Violence Archive, a nonprofit that tracks gun violence in America, defines mass shooting as incidents where “FOUR or more shot and/or killed in a single event, at the same general time and location not including the shooter.”
TheDCNF examined the number of mass shootings committed per city in that 17-month period, and found that Chicago made up about 10 percent of those incidents. Of the 521 mass shootings committed, approximately 53 occurred in the city of Chicago.
Chicago, on average, represented about 11 percent of total mass shootings in the country each month. The city, racked by gang violence, sees about three mass shootings per month, according to the data.
