Life expectancy research and data
Explainers and downloadable tables built from CDC, NCHS, and SSA data. No independent statistical reviewer has checked the explainers yet, and each article says so under its byline.
Datasets and explainers
The research library is temporarily withheld from search and directory listings until each mortality-statistics explanation receives independent domain review. The source datasets remain available on the data page.
What this library covers
This library explains the public model and the research it uses. It does not publish personal longevity advice, diagnose health, or convert population associations into individual recommendations.
The review notice stays under each byline and in the page’s search metadata until a qualified human reviewer, named on the page, approves the article.
Start with the complete methodology or inspect the current data. The methodology explains why the generation model doesn’t adjust its estimate for having already survived to a reader’s current age.
