We want every figure on this site to be right. If something is wrong or out of date, we fix it.
How to report an error
Tell us the page, the statement or figure, and the source that shows the correct information. Our contact form is coming soon on the Contact page.
What we do
- We check the report against the original source.
- If we made an error, we correct it promptly and update the “last updated” date on the guide.
- If a correction changes a guide’s main conclusion, we add a short note saying what changed and when.
