Report an error

If a fact on this site does not match its source document, please say so. Every report is checked against the source document.

What to include

1. The address of the page with the error.
2. The fact: its fact id (under Details on a row, or beside the fact), or the words as the page shows them.
3. The source document and page number that shows the right value.

Send it

• Open an issue on GitHub (opens in a new tab): it asks for the page, the fact id and what the source says. Needs a free GitHub account; the report is public, so it asks for no personal details.

What happens next

The report is checked against the source document. The site shows what the source document says, never a changed value without a source, and every change is recorded on the Changes page. See how corrections work.

This page stores nothing about you and sends nothing. The link above opens GitHub only when you choose it.
