Mass shootings – incidents that injure or kill greater than four people, not such as the perpetrator – rose nearly 50% in 2020 amid the pandemic that left millions unemployed and tens of millions more teenagers idle.
USA TODAY evaluation of Gun Violence Archive statistics show mass shootings rose from 417 in 2019 to 611 in 2020, inclusive of 95 incidents in June 2020 alone.
While incidents are down from the height of the COVID-19 shutdowns, the 103 incidents in 2021, as of March 22, are 53% greater than the 1st-quarter average of the past 4 years.

“Those numbers are sobering,” said Sarah Burd-Sharps, director of research at Everytown for Gun Safety, a nonprofit that works to limit gun violence nationally. “There are lots of theories flying left and right as to why this passed off and it’s too early to tell, but what’s clear is that it was a very lethal year.”
Mass shootings claimed 513 lives in 2020 – 96 more than 2019 – however the average number killed fell to under a person per incident, and the last mass taking pictures that claimed 10 or more lives occurred in August 2019 at an El Paso, Texas, Walmart.

Colorado incidents have figured prominently in the records of U.S. mass shootings from the two students who killed 13 and injured 24 at Columbine High School in 1999 to the 12 killed and 70 injured for the duration of a 2012 midnight screening of "The Dark Knight Rises" at an Aurora theater.

USA TODAY and its companions define mass killings as incidents with at least four victims. That's occurred 102 times in 33 states and the District of Columbia in the past forty years, according to Mother Jones' mass shooting database.
Coloradans have suffered 4 mass killings since 1982 – a quarter of the mass killings that have been perpetrated in California in the same period.
