Public sector

Area metrics that survive FOI and procurement review.

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

Four things that hold up at review.

It admits what it cannot tell, keeps each nation separate, replays any analyst query, and never touches personal data.

It says when it cannot tell

Thin evidence returns no number instead of a guess. A council briefing never carries a fabricated move.

Percentiles within each nation

Three different methodologies on three release schedules. We never merge them into a cross-border rank.

Replay any analyst query

Natural language becomes a typed plan. Store it with the paper and re-run the exact query on demand.

No personal data

Everything is neighbourhood-grain aggregate statistics. Nothing about residents of the areas you query.

Why it survives FOI

Made to be published, not just used.

A reviewer asks where a figure came from and whether it still holds. The answer is in the response.

Never invented

Every value points at a source. Where we cannot back a number, we return nothing rather than fabricate one.

Pinned for the contract

Pin the version named in the procurement notice. The number on the deliverable matches the one at award.

Public, citable method

The methodology is published and versioned. Cite the page and the exact engine version behind any figure.

Frequently asked

Questions a research or analytical unit asks first.

Will the numbers survive an FOI response?

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.

Can we pin the methodology for a procurement deliverable?

Yes, owner-only. Pin the engine version named in the procurement notice and every response honours it. Two calls under the same pin return the same numbers, so the figure on the deliverable matches the one at award, across the whole contract timeline.

Do you cover Northern Ireland?

Not yet. England, Wales and Scotland are covered today, each with its own national deprivation methodology. Northern Ireland is on the roadmap. Until then an NI postcode returns null rather than a fabricated cross-border value, which is the honest answer for a published figure.

What do you store about residents of the areas we query?

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.

Sourced, dated, and built for the publication.

Pin the methodology for the contract cycle, cite the exact version behind every number, and know it will hold at FOI and procurement review.
