Data on gun violence can be notoriously hard to find and compile. There is no comprehensive national plan for gathering and disseminating firearms use and injury data, according to NORC.
Operations like the Gun Violence Archive aim to fill in the gaps. A new datahub from The Trace is another project hoping to make up for the dearth in gun violence data. The K-12 School Shooting Database tracks school shootings nationally, which this page has also covered.
