1 Introduction

With a goal of reducing both morbidity and mortality, we estimated the frequency and severity of active shooter events in the U.S. from 2013-2015, based on data from http://www.shootingtracker.com who track both injured and killed, and who dene an event as when at least 4 people are shot.

Using data downloaded 2015-12-05 we used R version 3.2.1 (2015-06-18) [1] to estimate the frequency and severity of events reported in the media (links to news stories available from http://www.shootingtracker.com).

2 Tables

Table 1 shows by year the number of events, the average number of events per week in each year, and (assuming a threshold to dene “high-prole”of ve or more killed for possible newsworthiness; this assumption can be easily changed) the average number of high-prole events per month in each year. Tables 2 through 4 show year-specic data per event.

Table 1: Overview of events by year

Year Events Events/wk High-prole events/mo*

2013 363 6.85 1.67

2014 336 6.34 1.38

2015 353 7.20 1.45

*A high-prole event is dened as 5 or more killed in an event.
