When the data changes, the page should show it.
Research pages are living documents, but updates should not silently rewrite history.
Factual errors
If a number, calculation, label or source interpretation is wrong, we correct it and update the modified date. Material corrections should include a visible note describing what changed.
Routine data updates
When an official dataset releases a new period, we may update the article, charts and downloadable data. The original publication date remains unchanged; the modified date changes.
Methodology changes
If a source changes definitions or a better dataset replaces the previous measure, the article should state that the series is not perfectly comparable rather than splicing the data without warning.
Disputes
A disagreement with our interpretation is not automatically a correction. If a source, definition or calculation is demonstrably wrong, it is.
Contact
Until a dedicated editorial inbox is added, correction requests can be submitted through the site's future contact channel. Every request should identify the page, claim and supporting source.
