A 2023 Pew Research Center poll (fielded fall 2022) found 22% of parents saying they are \"extremely or very worried\" that any of their children might get shot at some point, and another 23% \"somewhat worried\" — about 45% combined. That ranks below worry about mental health (40% extremely/very worried) and bullying (35%). The worry level bears little relationship to the base rate: parents in low-crime suburbs report similar levels of concern to those in high-crime urban areas.

Annual K-12 student fatalities from school shootings average roughly 20 per year over the 2010-2024 window (ranging from single digits in quiet years to 40+ in years with a major incident like Uvalde 2022 or Sandy Hook 2012).
