Everytown tracked 500-plus incidents of gunfire on school grounds since 2018, yet the injuries and deaths span decades and categories that don’t fit any simple narrative. The Gun Violence Archive and other datasets also point to stark scale differences, including 82 K12 school shooting incidents in 2023 and 851 K12 school shooting fatalities recorded by K12SSD from 1970 to 2023. This post pulls those sources together to show what “school shooting statistics” really add up to and where the gaps hide.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
