The evidence library

Every figure used anywhere on this site, with its source, in one indexed place. Check any of it. We would rather you did.

How this page works

A filterable table. One row per claim. Each row carries the figure, the claim it supports, the full citation, the year, and a link to the source where one exists. Filterable by topic — prevalence, mortality, biology, economics, incarceration.
