Experienced researchers in gun violence related criminology were invited to attend the Inaugural Statistics Serving Society (S3) Forum held on June 26 and 27, 2019 to discuss the trends and issues related to the violence of gun use. The workshop program suggested that there are many problems but not sufficient numbers of involved statisticians. The principal purpose of the Forum was to expose the opportunities and needs for statistical efforts and to engage a substantial number of statisticians to work across disciplinary lines to help in understanding and mitigating the effects of gun violence. The forum involved all researchers in contributing their own part to a better understanding the issues and trends. The forum was broken into 5 topic areas: Emerging Data Sources, Gun Violence Trends, Policing Gun Violence, Assessing Gun Violence Risks and Evaluating Initiatives, and Police Shootings.

Gun violence is a vexing problem in the U.S. which necessarily justifies this scrutiny.  In honor of Ingram Olkin (1924-2016), a principal founder of NISS and an internationally prominent statistician whose work stressed the importance of statistical thinking in studying major societal problems, NISS is proud to be the sponsor of the Ingram Olkin S3 Forums. These Forums are aimed at engaging scientists and stakeholders in addressing the compelling issues facing contemporary society and exploring the roles that statisticians and data scientists can bring to address these issues.

About the Ingram Olkin Forum: Statistics Serving Society (S3) Series

Ingram Olkin Forums (IOF) are a series of forums to honor the memory of Professor Ingram Olkin presented by the NISS IOF committee Statistics Serving Society (S3).  

Each forum focuses on a current societal issue that might benefit from new or renewed attention from the statistical community. The S3 Forums aim to bring the latest innovations in statistical methodology and data science into new research and public policy collaborations, working to accelerate the development of innovative approaches that impact societal problems. As the Forum will be the first time a particular group of experts will be gathered together to consider an issue, new energy and synergy is expected to produce a flurry of new ideas and approaches.
