What every article here carries

Standards

Four things are required of every piece in the almanac, and they are required by the content schema rather than by convention: an article missing any of them fails the build rather than publishing without it.

  1. A short answer at the top. Two sentences, above the fold, before any preamble. If you came from a search result you should not have to read 1,400 words to get what you came for.
  2. At least one original figure built from the same sourced datasets the tools use, rather than a screenshot or a borrowed chart.
  3. A named source list at the foot, with links to the documents themselves.
  4. A byline and a publication date. Articles are signed with the same name, and dated the day they go up.

Articles on heat, health, legal or financial questions are held to a further rule: they cite official guidance only, state the limits of what they can tell you, and do not give individual advice. That rule is set out in full in the editorial policy.
