GUNS OF AMERICA

Even though it has half the population of the other 22 nations combined, the United States accounted for 82 percent of all gun deaths. The United States also accounted for 90 percent of all women killed by guns, the study found. Ninety-one percent of children under 14 who died by gun violence were in the United States

Between 1966 and 2012, there were 90 mass shootings in the United States. Mass shootings are defined for the study as having four or more victims and don't include gang killings or slayings that involve the death of multiple family members.

A mass shooting is an incident involving multiple victims of gun violence

The 90 U.S. mass shootings are nearly a third of the 292 such attacks globally for that period. While the U.S. has 5% of the world's population, it had 31% of all public mass shootings

While the U.S. has had more mass shootings in terms of raw numbers than other countries, at least three European countries—Switzerland, Norway and Finland—had higher rates of mass-shooting deaths per capita, according to researchers Jaclyn Schildkraut of the State University of New York in Oswego and H. Jaymi Elsass of 

In fact, rifles are the least popular killing tools in the United States. Per the FBI, this is how Americans killed each other in 2014: Handguns: 5,562 (47 percent) Unknown firearms: 2,052 (17 percent) Other weapons: 1,610 (13 percent) Knives and Cutting Instruments: 1,567 (13 percent) Hands, feet, fists, pushing: 660 (6 percent) Shotguns: 262 (2 percent) Rifles: 248 (2 percent)
