Johns Hopkins Center for Gun Policy and Research

Additional Areas of Research

The Center is constantly exploring risk factors for gun violence to better understand and prevent the burden of gun violence.

Center faculty conduct research on connection between alcohol and substance use and gun violence, as well as issues around mass shootings, mental illness and school safety. We occasionally consider proposals to research specific gun violence topics from Foundations or private individuals.

Key Statistic

Alcohol outlets in Baltimore that sell alcohol for off-premise consumption (such as liquor stores and beer and wine stores) have a stronger association with incidences of violent crimes, including homicides, aggravated assaults, sexual assaults, and robbery, than alcohol outlets in Baltimore where alcohol is bought and consumed on-site, such as bars and restaurants. A 10 percent increase in access to liquor stores and beer and wine stores has a 37 percent greater association with violent crime than the same increase in on-premise outlets. [1]

“A comprehensive approach to reducing violent crime in Baltimore must include policies that restrict or regulate alcohol outlets, particularly those that sell alcohol for off-site consumption. Reducing the number of off-site alcohol outlets in Baltimore has the potential to lead to fewer homicides and aggravated assaults.”

– Daniel Webster, Center Director
