SST 2016 National Gunfire Index - Illegal Gunfire continues to be an issue for U.S Urban Cities

ShotSpotter has released the 2016 National Gunfire Index (NGI), an analysis based on gunfire data aggregated from 72 cities across the U.S. (including Puerto Rico and the U.S. Virgin Islands). The number of gunfire incidents has increased year over year -- In 2016, ShotSpotter published nearly 75,000 gunfire incidents in U.S. cities compared to 54,699 published incidents in 2015. This data confirms that illegal gunfire remains an issue for many communities.

How to use the NGI
We invite you to use this NGI report as a tool to better understand gunfire trends in communities, while also comparing the gun violence incident stats to other ShotSpotter monitored cities.
