Local electoral area

A local electoral area (LEA; ) is an electoral area for elections to local authorities in Ireland. All elections use the single transferable vote. The Republic of Ireland is divided into 166 LEAs, with an average population of 28,700 and average area of . The boundaries of LEAs are defined by statutory instrument, usually based lower-level units called electoral divisions (EDs), with a total of 3,440 EDs in the state.
As well as their use for electoral purposes, LEAs are also used for general statistical purposes, such as reporting local outbreaks of COVID-19.
Municipal districts.
A municipal district () is a division of a local authority which can exercise certain powers of the local authority. They came into being on 1 June 2014, ten days after the local elections, under the provisions of the Local Government Reform Act 2014. Of the 31 local authorities, 25 are subdivided into municipal districts, which comprise one or more LEA. The exceptions are the three city councils (Cork City, Dublin City and Galway City) and the three county councils in Dublin (Dún Laoghaire–Rathdown, Fingal and South Dublin). A district associated with a city or borough is termed a metropolitan district ("ceantar cathrach") or borough district ("ceantar buirge") respectively.
In 2019, John Paul Phelan, Minister of State for Local Government and Electoral Reform, commented in the Dáil:
Boundaries.
Boundaries for local electoral areas and municipal district are determined by statutory instrument of the Minister for Housing, Local Government and Heritage. The minister must first establish an independent boundary committee, but need not accept its advice. A boundary committee has been required since 1994 for electoral areas. The 2012–13 Local Electoral Area Boundary Committee considered both administrative areas (municipal districts, though not counties/cities) and electoral areas. In 2015, separate committees were set up to consider adjustments to county and municipal boundaries passing through each of four urban areas: Athlone, Carlow, Drogheda, and Waterford. A Boundary Committee established in 2017 and which reported in June 2018 recommended alterations to municipal districts and local electoral areas which were implemented in December 2018.
The current government plans to introduce an Electoral Commission in 2021, which would replace the Local Electoral Area Boundary Committees as well as handling other functions relating to elections and referendums in the state.
