How we work
Our maps and tools are built from primary data, and each one names its source.
Every article shows when it was last updated. Data tools state the period they cover: the Areas to Avoid maps, for example, cover October 2025 to September 2026.
When a source publishes new figures, we rebuild the map from them.
