Depressants Statistics

Depressants charts the gap between how common depression is and how unevenly treatment reaches people, with 4.4% of U.S. adults reporting depression treatment in 2022 alongside worldwide depression affecting 5.0%. It also pulls together what works and what it costs, from effect sizes like antidepressants reducing symptom severity by about -0.31 to therapies such as high intensity CBT priced around £20,000 to £30,000 per QALY, plus the market trajectory that is forecast to keep accelerating.

Depressants touch millions of lives, yet the need still outpaces treatment. In 2022, 21.7% of U.S. adults reported any mental illness in the past year while only 4.4% reported depression treatment, even as depression and anxiety disorders drove global years lived with disability up by 40% from 1990 to 2019. This gap matters because the same evidence base also quantifies what works, what improves symptoms fastest, and where adherence and access shift outcomes.

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
ChatGPTClaudeGeminiPerplexity

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
ChatGPTClaudeGeminiPerplexity

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
ChatGPTClaudeGeminiPerplexity

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
