01 — The problem
The insight is in the overlap
The UK publishes some of the best open social data in the world — deprivation, recorded crime, digital exclusion — but each is built by a different body, on a different geography, on a different timetable. Almost nobody joins them up.
A neighbourhood can look ordinary overall, yet sit in the worst decile for crime and at high risk of digital exclusion — a compounding problem invisible one layer at a time.
01Mismatched geographies
Data is at neighbourhood level; decisions are at ward, town, district and nation.
Why this is hard
Statistics are published for small fixed areas drawn for counting, not for governing. Wards, towns and districts cut across those areas, so answering a question about a real place means re-cutting the figures — and re-cutting is where meaning quietly gets lost.
02Four nations, four rulebooks
England, Scotland, Wales and Northern Ireland each measure deprivation differently.
Why this is hard
Each nation builds its index from its own indicators and its own weightings. Each is sound inside its own border, and a rank in one is not the same thing as the same rank in another — so a UK-wide picture cannot be made simply by laying them side by side.
03Buried in spreadsheets
The people who need the patterns — councillors, community groups — are not analysts.
Why this is hard
The data is public and the formats are open, which is not the same as usable. Someone asking about their own street has to know which files to join, and how, before the question can even be put.
02 — The question
How might someone see where different kinds of disadvantage fall on the same people and places, when each kind is counted and held separately?
The question deliberately does not say what an answer looks like. A build, an analysis, a design or a shared standard can all answer it — see the four tracks.
03 — The mission
Reveal where disadvantage overlaps — and where the map defies the assumption
Cross-map at least three layers — deprivation, crime, digital exclusion — across real geographies, and turn the result into something a decision-maker would find useful.
