Slate partners with @GunDeaths for an interactive, crowd-sourced tally of the toll firearms have taken since Dec. 14, 2012.

By Chris Kirk and Dan Kois

The answer to the simple question in that headline is surprisingly hard to come by. So Slate and the Twitter feed @GunDeaths are collecting data for our crowd-sourced interactive. This data is necessarily incomplete. But the more people who are paying attention, the better the data will be. You can help us draw a more complete picture of gun violence in America. If you know about a gun death in your community that isn't represented here, please tweet @GunDeaths with a citation. And if you’d like to use this data yourself for your own projects, it’s open. You can download it here.
