Get in touch
Dyaan is a small, independent project — real questions reach a real person. Write to us for any of the following, or anything else:
- A correction — you spotted a figure, a source or a claim on the site that looks wrong.
- A place you'd like measured for a future field note.
- A data source we should add, or one we've described inaccurately.
- Press, research or partnership enquiries.
- Anything about how the tool works — see the methodology page first, it answers most "how is this calculated" questions directly.
We read every message. Response times vary since this is an independently run project, but we do reply.
