About
Corrections
When we get something wrong, we fix it in public and say what changed.
Our policy
If a number, fact or chart on this site is wrong, we correct it as soon as we can confirm the error. We note the correction on the page where it appeared, with the date and what changed, and we list it here.
We don’t quietly edit published figures. If a source revises its own data, we update the tracker and record the revision.
To report an error, contact us with a link to the page and, if you can, the source you’re relying on.
