Electoral Commission Ireland — constituency boundaries, voter registration & the 2024 map
The Electoral Commission expanded the Dáil from 160 to 174 seats and the number of constituencies from 39 to 43 for 2024. Census 2022 data drove every decision — Ireland had grown to 5.15 million. The data is below.
What the Electoral Commission does
The Electoral Commission, established on 9 February 2023 (electoralcommission.ie, checked 2026-10-22), conducts the constituency reviews for Dáil and European Parliament elections.
The 2024 constituency boundary review
Census 2022 triggered the Electoral Commission's first review. Ireland's population had reached 5.15 million — a 8.1% increase from 2016 — so the Dáil needed more seats. In the 2024 map each constituency returns 3–5 TDs.

Electoral register Ireland — how to check and update
The Electoral Commission oversees the modernised electoral register and sets standards for how it is maintained and updated (electoralcommission.ie). Check your registration at checktheregister.ie.
- Check your registration: checktheregister.ie — the official Electoral Commission voter lookup tool. Enter your name and address to confirm you are registered correctly.
- Update or register: Submit your application to your local county or city council. Find all council links at electoralcommission.ie.
- Eligibility: Irish citizens and EU citizens living in Ireland can register for Dáil elections. UK citizens living in Ireland can vote in local elections. Non-EEA citizens can vote in local elections only.
- Deadline: You must be registered before an election is called. Continuous registration means no annual deadline — but register well ahead of any expected election.
Why constituency boundaries changed in 2024
The Electoral Commission draws constituency boundaries from Census population counts. Census 2022 population counts by electoral division are mapped on IrelandInsights.
IrelandInsights maps Census 2022 population at electoral division level — the same census the Electoral Commission used for its boundary review.
