While the popular perception may be that mass shootings are the nation’s largest share of gun deaths, the data tells a different and more complex story. In reality, mass shootings are the tip of the iceberg of this country’s [United States] gun violence crisis. More than 99 percent of gun deaths in the US are from shootings other than mass shootings.3 Nevertheless, because of the high number of casualties and often extensive and horrific media coverage associated with them, each mass shooting sends shockwaves of pain and harm through families, communities, and the nation. Just like the daily gun violence that contributes to the more than 100 gun deaths each day in the US, mass shootings are largely preventable through evidence-based policy interventions.

This analysis reflects a compilation of 10 years (2009 to 2018) of original data on mass shootings in the United States, sourced from media reports and official police and court records. These records enable unique insights into the circumstances of mass shootings.(From the website). Section 6 describes the link between domestic violence and mass shootings. Record #6661
