Data Sources

Every number on this site comes from one of the sources below. A daily job at 00:00 UTC fetches each source that is due, keeps the last good copy when a fetch fails, and rebuilds the site. A value whose source has not updated for twice its usual interval is marked stale. Nothing is estimated. Hand-maintained content (the reference lists at the end, and the “Reference” boxes on some pages, such as historical milestones and policy targets) shows when it was last reviewed.
