Statistics that fail independent corroboration are excluded.

Recent reports from 2025 put spotlight on birth trauma, showing how often serious complications land with lasting physical and emotional effects. What’s striking is the mismatch between what many people expect from birth and what large datasets record across hospitals and settings. These figures help explain why small differences in outcomes can matter enormously for families, and they raise hard questions the full data can’t dodge.

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.
