Violence is a significant problem within the U.S. The purpose of this project is to help prevent violence through better understanding what increases or decreases risk for violence, specifically political violence of all types (e.g. far right and far left). Understanding this will help inform violence prevention programs and policies. We will conduct a large-scale one-time survey of risk and protective factors related to attitudes towards political violence using population-wide sampling. The survey will include about 2000 people. The survey includes questions about grievances, mental health, social connection, trauma experiences, childhood experiences, faith, views of government, internet use and attitudes towards the use of violence for political change.
