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 cases from 1982-2012 and has since been expanded numerous times to remain current. For analysis and context on this data—including how we built the database, and a change to the baseline for victim fatalities with cases dating from January 2013—see our Guide to Mass Shootings in America, which includes an interactive map documenting all of the cases.

THE BIG QUESTION...

as we head into 2020 is whether politics and media will be a billionaires’ game, or a playing field where the rest of us have a shot. That's what Mother Jones CEO Monika Bauerlein tackles in her annual December column—"Billionaires Are Not the Answer"—about the state of journalism and our plans for the year ahead.

We can't afford to let independent reporting depend on the goodwill of the superrich: Please help Mother Jones build an alternative to oligarchy that is funded by and answerable to its readers. Please join us with a tax-deductible, year-end donation so we can keep going after the big stories without fear, favor, or false equivalency.
