US Mass Shootings, 1982-2019: Data From Mother Jones’ Investigation

The full data set from our in-depth investigation into mass shootings.

Editor’s note: This database originally covered 1982-2012 and has since been expanded through 2019. For detailed context and analysis on this data (including an explanation of how we built the database), see our Guide to Mass Shootings in America, which includes an interactive map documenting all of the cases.

You can view and download the database in its entirety by clicking here. (The embedded version below does not support expanding the cells to see the full text in some places, so use the above link to do so.)

 

THANK YOU.

We recently wrapped up the crowdfunding campaign for our ambitious Mother Jones Corruption Project, and it was a smashing success. About 10,364 readers pitched in with donations averaging $45, and together they contributed about $467,374 toward our $500,000 goal.

That's amazing. We still have donations from letters we sent in the mail coming back to us, so we're on pace to hit—if not exceed—that goal. Thank you so much. We'll keep you posted here as the project ramps up, and you can join the hundreds of readers who have alerted us to corruption to dig into.
