We read everything. Rate corrections get a reply within a few business days, because every number on this site depends on them being right.
What to include
- For a rate correction: which figure, what you believe it should be, and a link to the official source.
- For a bug: the tool you used, the inputs you entered, and what you expected to see.
- For a topic suggestion: the question you were trying to answer when you landed here.
Other ways to reach us
Source code and issue tracking for this site live on GitHub. That is the right place for reproducible bugs; email is faster for rate questions.
