For Public Sector
Every value carries its source, its release date and a confidence. Percentiles are ranked within each nation, the methodology is public, and the engine version is stamped on every response.
Built for the publication trail
It admits what it cannot tell, keeps each nation separate, replays any analyst query, and never touches personal data.
Thin evidence returns no number instead of a guess. A council briefing never carries a fabricated move.
Three different methodologies on three release schedules. We never merge them into a cross-border rank.
Natural language becomes a typed plan. Store it with the paper and re-run the exact query on demand.
Everything is neighbourhood-grain aggregate statistics. Nothing about residents of the areas you query.

Why it survives FOI
A reviewer asks where a figure came from and whether it still holds. The answer is in the response.
Every value points at a source. Where we cannot back a number, we return nothing rather than fabricate one.
Every figure names the methodology version behind it, and every release is published with what it moved, so a footnote can say exactly which method produced a number.
The methodology is published and versioned. Cite the page and the exact engine version behind any figure.
Frequently asked
Yes, by construction. Every value carries its source, observed period, and a plain-language confidence. The methodology is public and the engine version is stamped on every response. Your FOI footnote can point at the source, the release and the exact version behind the figure.
Yes. Every response carries the methodology version that produced it, the methodology page is public, and the changelog lists every release with the figures it moved. Cite the version with the figure, and a reviewer can see exactly what has changed since.
No. England, Wales and Scotland are covered, each with its own national deprivation index and geography. Northern Ireland is not covered, and an NI postcode returns an empty value rather than a cross-border estimate, which is the honest answer for a published figure.
Nothing. Everything is neighbourhood-grain aggregate statistics, not personal data. We hold your org, your members and your API keys, plus optional saved settings. No information about individual residents of the areas you look up.
Cite the exact version behind every number, with its source and period, and know it will hold at FOI and procurement review.
