How we work
Sources you can check
Our maps and tools are built from primary data, and each one names its source.
Named sources

- Regions of Brazil IBGE 2026
- Regions of Japan 2025 census
- Map of Canada StatCan 2026
- Regions of Switzerland BFS 2025

Dated, and kept current
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.
