- Females represent 35% of car crash TBIs in emergency visits, compared to 65% males
- Children under 5 years comprise 10% of pediatric TBIs from vehicles
- In the United States, motor vehicle crashes account for approximately 17.3% of all traumatic brain injuries (TBIs) treated in emergency departments annually
- Globally, road traffic accidents cause over 1.35 million deaths yearly, with head injuries contributing to 50% of these fatalities
- From 2006 to 2014, US emergency departments saw 2.535 million TBIs from motor vehicle crashes, averaging 281,667 per year

How We Rate Confidence
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.
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
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
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
