A Thursday shooting at an Iowa school that left a sixth-grader dead and at least five other victims wounded continued a troubling trend of school shootings in the U.S. and marked the fourth such incident in the U.S. already in 2024.

Though the devastating impact of school shootings – and of lives lost to any sort of violence – cannot be adequately captured by data and charts alone, they can help illustrate the tragic toll and geography of incidents that have become disturbingly prevalent in the U.S. in recent years.

In 2023, there were 346 school shooting incidents across the country, meaning the U.S. averaged nearly one incident every day and saw its highest total on record since at least 1966. California and Ohio tied for the most incidents among states last year, at 25 each, while Texas saw 23 in that period. Nationwide, the incidents resulted in 248 victims either wounded or killed, not including the shooter. Texas saw the highest number of casualties among states, at 21 victims in 2023, followed by Maryland (20) and California (18).
