The charts stay free. The data is what you pay for.
Reading this site will always be free and there will never be advertising on it. What costs money is the layer underneath: licensed primary feeds, direct pulls instead of compiled series, and keeping the policy tables accurate as schemes change mid-year.
One-off contributions are welcome too, and are the best option if you just found something here useful and want to say so.
Where the money goes
Data donations fail when nobody says what the money buys. Here is the list, in priority order.
What you get, concretely
Paid tiers get the datasets in the form an analyst actually needs, which is not a webpage:
- One row per country per year per metric, in CSV and JSON, with the source key and vintage on every row — so a figure in your model can always be traced back.
- A confidence flag on every value, distinguishing a published headline figure from one this site compiled, normalised or derived. Nothing else in this space reliably does that, and it is the difference between a number you can cite and a number you can only quote.
- A change log, so when Ember restates 2023 or Swiss Re revises a loss total, you can see what moved rather than discovering it in a reviewer's comment.
- The normalisations, written down. Where this site scales a generation mix to 100%, or splices two temperature datasets, the exact operation is documented.
Note for whoever is deploying this. Payments are not wired up yet, on
purpose. Paste hosted checkout URLs into data/support.js and the buttons
activate — nothing else needs to change. Use Stripe Payment Links, Ko-fi, GitHub Sponsors
or Open Collective so that card details never touch this codebase and the site stays static.
