How to use the Canvass Planner

The Canvass Planner ranks every Electoral Division (ED) in a constituency by how likely a door-knock is to pay off for your party — and, separately, by transfer opportunity. It shows you, concretely, where to send your canvassers and why. This guide covers the desktop and mobile workflow, the two models behind the scores, and the questions teams ask most.

Before you start: the Canvass Planner is an Analyst feature — you need an active Analyst subscription to load constituency scores. The map, party picker and constituency search all live in the Elections layer.

What it is

Most canvassing plans start from a paper map and a hunch. The Canvass Planner replaces the hunch with two independent models, viewed as three ranking lenses. Pick a party and a constituency. The planner ranks every ED, paints them on the map, and bundles the top ones into a ready-to-run session plan.

It targets — it does not count votes. Ireland counts no ballots at ED level. Both models estimate from demographics and past results. Read them alongside your own local knowledge.

Two models, three lenses

The planner runs two separate models and lets you switch between them. They don't always agree — an area can be strong support and weak transfer opportunity, or the reverse — which is deliberate: they measure different things.

Most votes support × doors Where the raw volume is. Best for seat arithmetic. USE WHEN: plenty of volunteers to cover ground. Most Efficient the demographic-model blend Most receptive doors per hour. USE WHEN: small team, short window. Best Opportunity the Opportunity Score A separate model, built from GE + LE 2024 transfers. USE WHEN: the seat depends on transfers.

The demographic model — "Most votes" and "Most Efficient"

A Ridge regression across all 43 constituencies links Census 2022 demographics to GE 2024 first-preference shares, blended with how easy an area is to canvass:

demographic model powers "Most votes" and "Most Efficient" 50% Support Potential does the area lean your way + 30% Density doors per minute walked + 20% Access how reachable on foot Normalised 0–1 within the constituency, then blended. Higher = a better door.

Most votes ranks by support × doors — expected votes, for seat arithmetic. Most Efficient ranks by the blend itself — the most receptive doors per hour, for when time is the binding constraint.

The Opportunity Score — "Best Opportunity"

A separate model, built from GE 2024 competitiveness and verified LE 2024 transfer counts. It answers a different question from the demographic model: not "where is our support," but "where would a transfer-focused push change the outcome."

opportunity score powers "Best Opportunity" — a separate model, built on transfers 40% 🎯 Potential Gain size of the transfer prize + 25% 🏁 Competitiveness how close to quota, GE 2024 + 20% 🔄 Transfer Advantage LE 2024 transfer over-performance + 15% 👥 Household Reach doors in that area A separate "Evidence" badge shows data strength alongside the score — it never changes the ranking.
An Evidence badge is shown alongside each Opportunity Score — it reflects how much supporting data backs the number, but it never changes the ranking. A high-opportunity, low-evidence area is exactly where a campaign should explore, not something the model suppresses.

Reading the markers

Two single-character markers can appear on an Opportunity Score row or its hover card — read them before trusting a top-ranked number at face value:

When you see no Opportunity Score results

An empty "Best Opportunity" list means one of three different things, and the panel tells you which:

On mobile & tablet

The planner works on all screen sizes. Open it from the layers panel (☰ → Elections → Canvassing). On mobile it opens as a bottom sheet — tap the amber ◎ button to collapse or reopen it. The constituency card sits at the top, collapsed to essentials; tap ▾ to expand it. In portrait mode you'll see a one-time "rotate for more room" hint.

Where to send your canvassers — and why

Match the lens and the EDs to your campaign's situation:

Need maximum seat volume?Lots of volunteers. → "Most votes", top of listHigh support × high doors. Short on volunteer hours?Small team, evenings only. → "Most Efficient", top of listHighest doors-per-hour. Seat depends on transfers?Tight STV last-seat fight. → "Best Opportunity", top of listHighest Opportunity Score. Building name recognition?Long run-in, brand to grow. → Dense, mid-support EDsMost faces per hour.

FAQ

Do I need a subscription?

Yes. The Canvass Planner is an Analyst feature. You need an active Analyst subscription to load constituency scores.

Are these real vote counts?

No — Ireland publishes no vote counts at Electoral-Division level. Both models are estimates: the demographic model from Census 2022 and GE 2024 first-preference patterns, the Opportunity Score from GE 2024 competitiveness and LE 2024 transfer patterns.

What's the difference between the three lenses?

"Most votes" and "Most Efficient" both come from the demographic model (support × density × access) — they rank the same numbers two different ways. "Best Opportunity" is a separate model entirely, built from transfer data, and can disagree with the other two.

Why does an area show no Opportunity Score at all?

Already-won seat, no GE 2024 candidacy, or — most commonly for a genuinely competitive party — real GE 2024 competitiveness with no positive LE 2024 transfer signal found anywhere in the constituency. See "When you see no Opportunity Score results" above.

What do the ◐ and ↗ markers mean?

◐ means the area wasn't compared against any real alternative — it's the only one that qualified. ↗ means the area is transfer-growth ground, not your party's strongest base there. Both are caveats on how to read a top-ranked score, not warnings that it's wrong.

What does "Transfer advantage observed" mean?

It appears when your party over-performed on transfers in that ED's Local Electoral Area in the verified LE 2024 count — a bigger share of transfers than its first-preference share, with a 5% evidence floor.

Where does the data come from?

Census 2022 (CSO) for demographics; GE 2024 result books (Houses of the Oireachtas) for first preferences and competitiveness; LE 2024 result books (Department of Housing, Local Government & Heritage) for the verified transfer counts behind the Opportunity Score.

How accurate is it?

Accuracy varies by area, party and lens. Both models work best as a relative ranking within a constituency, not as an absolute prediction. Always read them alongside local knowledge.

Can I use it on my phone at the doors?

Yes. On mobile the planner becomes a bottom sheet with a floating button. The constituency card collapses to a tappable top card. Rotate to landscape for more map.

Get started

Open the planner, pick your party and a constituency, and start from the top of the ranked list — "Most votes" for volume, "Most Efficient" for efficiency, "Best Opportunity" when transfers decide the seat.
