Support the research

This atlas is free, with no ads and no trackers. Researching in depth, checking every source and keeping two languages takes time and costs money. If you find it useful, you can help sustain it.

The contribution link is not active yet. In the meantime, the best help is to share the atlas.

What it pays for

• Research time: reading the full studies, not just the headlines, and checking every figure.
• Access to sources: paywalled papers, databases and archives.
• Compute and tools: data analysis and visualizations.
• Hosting and maintenance of the site in both languages.

What does not change

Contributing does not buy content or influence the conclusions. Everything published stays open to everyone, whether they contribute or not. If we ever accept funding from an organization, we will say so here.

Can’t contribute? Sharing the atlas with someone who would care about it helps almost as much.
