Corrections Policy

How we correct

When we get something wrong we correct it on the same URL, note the date and the nature of the correction at the top of the story, and never silently rewrite history. The original error is described, not deleted from the record, so a reader who saw the first version can see what changed and why.

What counts as a correction

What is never corrected by editing

Archive snapshots are immutable. If a snapshot recorded a trend at a given rank at a given time, that record stays as it was recorded, even if later reporting changes the underlying story. A correction to how a snapshot is interpreted goes into the story or topic page as a new note; it does not rewrite the snapshot file. The same rule applies to the daily roll-up: a correction is a new record, not an overwrite.

How to request a correction

Use the Contact page and include the story URL, the exact passage, what you believe is correct, and the source that supports it. Requests without a source are logged but cannot be verified, and will not be treated as confirmed corrections.
