Clinical Depression Statistics

GITNUXREPORT 2026

Clinical Depression Statistics

Depression affects about 5% of adults in many high income settings and contributes to roughly 193.8 million DALYs worldwide in 2021, but the most urgent takeaway is how it tracks beyond mood into heart disease, stroke, and even higher type 2 diabetes risk. You will also see how treatment access is uneven, with the US using mental health services at 59.2% and the UK leaving 15% of adults with depression without treatment, alongside the staggering economic price tag of depression globally.

Clinical depression is a major health issue, yet the scale of its impact can still feel surprising even to people who think they know it well. Globally, depressive disorders accounted for 193.8 million DALYs in 2021, and 700,000 people die by suicide each year. In this post, we line up prevalence, disability, comorbid risks like heart disease and diabetes, treatment gaps, and costs to show how depression affects lives in ways that statistics can make sharply visible.

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.
