Nearly 1 in 2 high school students, 48%, were reported to feel sad or hopeless this past year, with girls far more likely than boys, according to the CDC 2023 data. Anxiety alone affects millions of students, from 38% reporting anxiety symptoms during COVID to 44% reporting persistent worry or anxiety symptoms. What’s striking is how often these struggles show up as missed activities, heavier substance use risk, and even suicidal thoughts, so the real story is not just how many students feel bad, but how that feeling reshapes a school year.

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
