The data

Every load-bearing number on this site, dated and downloadable as JSON or CSV, under CC BY 4.0.


The figures here aren't one-off snapshots scraped and left to rot. Each is kept as a dated series: when a number is re-checked, the new reading is recorded alongside the old, so the history stays visible and the trend is something you can audit rather than take on trust. Use any of it; the only ask is attribution.

A ready-to-paste citation and BibTeX entry sit beside each chart in the articles. How the numbers are made: methodology. These are sourced figures, not advice — see not advice.
