Preview: Gun Violence 20/20 City Tracker

Our City Tracker is designed to inform data-driven, community-based responses to bend the curve on city gun violence.


Gun violence in U.S. cities has surged since the start of the COVID-19 pandemic.


Gun homicide increased by 35% from 2019 to 2020 in the 100 most populous U.S. cities. But city-level data are scarce. There are few cities where residents can easily find and interact with official statistics on how gun violence incidence has changed over the past year.

To support data-driven, community-based responses to bend the curve on city gun violence, we compiled data from the  Gun Violence Archive , a non-profit organization that uses reports from news media and other public sources on gun violence. These are not official statistics, and may not capture every single gun violence incident. However, trends in the Gun Violence Archive data closely track the trends found in official statistics, making them useful for understanding changes in gun violence over time.

Below, you can interact with yearly and monthly Gun Violence Archive data for all 100 cities, from January 2018 through February 2021. In the coming weeks and months, we will update these data and provide additional analyses to inform local problem-solving.

In the coming weeks and months, we'll be sharing more interactive analyses from the Gun Violence 20/20 project, focused on racial disparities, the built environment, police violence, and other topics, through our  RISE Lab at BU  website.
