Mass Shooter Database
Funded by the National Institute of Justice (award number 2018-75-CX-0023), and recipient of international media attention, the mass public shooter database project includes four phases:
1. Creation of a comprehensive database of over 150 mass public shootings from 1966 to 2018 coded through over 50 individual-level psycho-social life history variables, including mental health history, trauma, interest in past shootings, and situational triggers.
2. Examination of community-level socio-ecological factors of where mass public shootings take place, including, but not limited to, crime rates, measures of social inequality, community mobility, availability of mental health resources, and prevalence of guns in households.
3. In-depth life history interviews with living mass shooters who are currently incarcerated and follow-up interviews with key stakeholders (e.g., family members, first responders, survivors) in the communities where shootings took place.
4. Dissemination of findings, creation of a public website, and implications for evidence-based prevention strategies.
N.B. we follow the Congressional Research Service definition of a mass public shooting: "a multiple homicide incident in which four or more victims are murdered with firearms—not including the offender(s)—within one event, and at least some of the murders occurred in a public location or locations in close geographical proximity (e.g., a workplace, school, restaurant, or other public settings), and the murders are not attributable to any other underlying criminal activity or commonplace circumstance (armed robbery, criminal competition, insurance fraud, argument, or romantic triangle)."
Preliminary results will be posted here in Spring 2019.
Gun Violence in America
The Violence Project has produced a 50 page comprehensive report on gun violence in America. This free report examines the history of guns in the United States, the prevalence of gun violence in our communities, trends in mass shootings, and the rise of “performance violence” in an age of social media.
