Corrections

Report an error

Email [email protected] with the page URL, the passage in question and, where possible, a source that supports the correction.

What happens next

• We acknowledge reports and check them against primary sources.
• Confirmed factual errors are corrected as soon as the correct information is verified.
• Material corrections are noted on the page and the modified date is updated, so readers can see the page changed.
• Typos and formatting fixes are made without a note, because nothing substantive changes.

Clarifications versus corrections

A correction fixes something that was wrong. A clarification adds context where the original wording could reasonably be misread. We label them differently rather than treating them as the same thing.

Calculator results

If a calculator returns a figure you believe is wrong, tell us the exact inputs you used. Our tool pages publish the formulas they apply so the maths can be checked independently.
