Corrections log

Current through Jun 12, 2026

Every correction across our section datasets is recorded here: section, what changed, why, and who requested it. The log is append-only — entries are never edited away. Corrections are free for everyone, always, and verified errors are fixed within five business days.

6 entries, newest first. Each links its change to a section, scope and the party that requested it.

An append-only, SHA-256 hash-chained audit log underlies the dataset: each dated entry commits to the entire published dataset and to the previous entry's head, so any later edit to past data is detectable. See each section's methodology for how changes are verified before they are published.
