How we write
We publish only what we've actually calculated and checked. Four rules decide what makes it in.
1
Agency documents
Figures come from the institution's own publication, with the link alongside.
2
Dated to a year
Every article says which year its figures apply to.
3
Our arithmetic, marked
Anything we worked out ourselves is labelled as ours.
4
What we could not verify
It stays in — with where you can check it yourself.
