Overview
Look up any part of Ireland.
3,420 Electoral Divisions, every census since 1841, and projections only where a model beat a naive baseline. Each figure names its publisher, its date and what it may be used for.

At a glance
Three horizons, three geographies
Each horizon rests on data published at a different level, and ATLAS keeps them apart: history by county, the present by Electoral Division, projections at whatever level the series is published. A county figure is never spread across the divisions inside it.
Worked examples
Each opens the map or a page already set to the view described.

How to read a label
Every material statement in ATLAS carries one of eight classes, so fluent prose cannot blur what was measured with what was inferred.
- Verified fact
- Directly established by a cited authoritative source for the stated place and period.
- Calculated indicator
- Produced deterministically from identified source fields by a reproducible formula.
- Inference
- A reasoned interpretation of stated evidence, with its reasoning shown.
- Scenario
- A conditional result from explicit inputs and assumptions. Never called a forecast.
- Forecast / projection
- Output of a named model, with owner, vintage, horizon and measured error.
- Assumption
- An input or analytical choice not established by source data, kept visible.
- Unknown
- Unavailable, incompatible, stale, too uncertain, or not measured. Shown as no data, not zero.
- Judgement required
- A matter for a named professional, statutory process or public body.
What this tool refuses to do
- It does not infer need, capacity, availability or eligibility from population or facility counts.
- It does not rank communities, and area context is never attached to an individual.
- It does not display a forecast that failed its backtest against a naive baseline.
- It does not blend measurement dates: every figure shows its own reference period.
- It does not compute any number with a language model.
The data behind ATLAS
Every source ATLAS uses or has identified, by theme, with where each one stands. Whether the checks on that data passed is on How ATLAS checks itself.
Measure and dataset names, and the registry detail describing them, are shown as their publisher issued them, not translated for this prototype.
