The number of U.S. active shooter incidents in 2021 jumped by 52.5% from the year prior, and between 2017 to 2021, there was a 96.8% increase, the FBI said in a report published this week. 

In 2021, there were a total of 61 active shooter incidents across 30 states, resulting in 103 people killed and 140 others wounded. The most occurred in the country's most populous state of California (6), followed by Georgia (5) and Texas (5). Four incidents each occurred in Colorado and Florida, the FBI said.

Among these shootings was one at an office building in Orange, California, and another at a grocery store in Boulder, Colorado.

June had the highest number of active shooter incidents (12), followed by April (10) and August (7). Most incidents were reported on a Saturday, followed by a Tuesday or Thursday, the agency’s data shows. A majority (32) of the 2021 shootings happened in "areas of commerce."
