“Over the 18 years from 1998 to 2015, our list contains 2,354 attacks and at least 4,880 shooters outside the United States and 53 attacks and 57 shooters within our country. By our count, the US makes up less than 1.15% of the mass public shooters, 1.49% of their murders, and 2.20% of their attacks. All these are much less than the US’s 4.6% share of the world population. Attacks in the US are not only less frequent than other countries, but they are also much less deadly on average.”
