Data & references
Free to cite, free to link
The things here are meant to be quoted. Original data I collected myself, and references I keep current by hand — each one states what it measures, when it was last checked and how it was made. Take what is useful, cite it with a link, and you never need to ask.
Original data
First-party — I ran these myself and published the method alongside the numbers. Nobody else has this data.

How to cite any of this
Every page above carries a Cite this page block with a copy-ready citation line and a plain-English description you can paste into your own piece. Everything is published under CC BY 4.0: quote it, chart it, build on it — commercially too — as long as you creditMarco Diversi and link back to the page you took it from.
Writing something and need a figure checked, or a number that isn't here yet? Ask me directly — I would rather you quoted something accurate than guessed.
