For the purpose of elections to Dáil Éireann, the country is divided into Constituencies which, under Article 16.4 of the Constitution of Ireland, have to be revised at least once every twelve years with due regard to changes in the distribution of the population. The Constituencies were last revised in 2023 and the Electoral (Amendment) No 40 Act 2023 contains details of their composition.Note: These constituencies will come into force at the next general election.This dataset is provided by Tailte Éireann

This dataset is the definitive set of regional council constituency boundaries for 2023 as defined by the regional councils and Local Government Commission but maintained by Stats NZ (the custodian). Constituencies are established under the Local Electoral Act 2001 and result from the division of a region for electoral purposes.

​

If a regional council decides to have a Māori constituency, the constituencies within the council are known as general constituencies and Māori constituencies. Constituencies are divisions of regional council areas. They are defined at meshblock level, and do not coincide with the statistical area 1 (SA1) geography or the statistical area 2 (SA2) geography. They are created, based on population, to be the voting areas within councils. Constituencies are required to reflect communities of interest. Their boundaries, so far as is practicable, coincide with those of territorial authorities or wards.

​

The boundaries of constituencies may be reviewed before each three-yearly local government election. Regional councils must review their representation arrangements at least once every six years. The provisions for such reviews are in the Local Government Act 2002.

​

Numbering

Constituencies are numbered based on their corresponding regional council. Each constituency has a unique four-digit code. The first two digits represent the regional council that the constituency lies within. The last two digits are sequential and represent the number of constituencies within a regional council. For example, the West Coast Regional Council (12) contains three constituencies, which are coded 1201, 1202, and 1203.

Geoscape Administrative Boundaries is Australia’s most comprehensive national collection of boundaries, including government, statistical and electoral boundaries. It is built and maintained by Geoscape Australia using authoritative government data. Further information about contributors to Administrative Boundaries is available here.

This dataset comprises seven Geoscape products:

• Localities
• Local Government Areas (LGAs)
• Wards
• Australian Bureau of Statistics (ABS) Boundaries
• Electoral Boundaries
• State Boundaries and
• Town Points

Updated versions of Administrative Boundaries are published on a quarterly basis.

Users have the option to download datasets with feature coordinates referencing either GDA94 or GDA2020 datums.

Notable changes in the May 2025 release

• Victorian Wards have seen almost half of the dataset change now reflecting the boundaries from the 2024 subdivision review. https://www.vec.vic.gov.au/electoral-boundaries/council-reviews/ subdivision-reviews.

  • There have been spatial changes (area) greater than 1 km2 to 66 wards in Victoria.

• One new locality ‘Kenwick Island’ has been added to the local Government area ‘Mackay Regional’ in Queensland.

  • There have been spatial changes(area) greater than 1 km2 to the local government areas 'Burke Shire' and 'Mount Isa City' in Queensland.

• There have been spatial changes(area) greater than 1 km2 to the localities ‘Nicholson’, ‘Lawn Hill’ and ‘Coral Sea’ in Queensland and ‘Calguna’, ‘Israelite Bay’ and ‘Balladonia’ in Western Australia.

• An update to the NT Commonwealth Electoral Boundaries has been applied to reflect the redistribution of the boundaries gazetted on 4 March 2025.

• Geoscape has become aware that the DATE_CREATED and DATE_RETIRED attributes in the commonwealth_electoral_polygon MapInfo TAB tables were incorrectly ordered and did not match the product data model. These attributes have been re-ordered to match the data model for the May 2025 release.

IMPORTANT NOTE: correction of issues with the 22 November 2022 release

• On 28 November 2022, the Administrative Boundaries dataset originally released on 22 November 2022 was amended and re-uploaded after Geoscape identified some issues with the original data for 'Electoral Boundaries'.
• As a result of the error, some shapefiles were published in 3D rather than 2D, which may affect some users when importing data into GIS applications.
• The error affected the Electoral Boundaries dataset, specifically the Commonwealth boundary data for Victoria and Western Australia, including 'All States'.
• Only the ESRI Shapefile formats were affected (both GDA94 and GDA2020). The MapInfo TAB format was not affected.
• Because the datasets are zipped into a single file, once the error was fixed by Geoscape all of Administrative Boundaries shapefiles had to be re-uploaded, rather than only the affected files.
• If you downloaded either of the two Administrative Boundary ESRI Shapefiles between 22 November and 28 November 2022 and plan to use the Electoral Boundary component, you are advised to download the revised version dated 28 November 2022. Apologies for any inconvenience.

Further information on Administrative Boundaries, including FAQs on the data, is available here or through Geoscape Australia’s network of partners. They provide a range of commercial products based on Administrative Boundaries, including software solutions, consultancy and support.

License Information

These boundaries comprise the proposed 64 general electorates released by the Representation Commission in March 2025 for public consultation. Written objections to the proposed electorate boundaries can be made between 25 March and 27 April 2025. Refer here for more information about having your say.

​

The Representation Commission is convened by the Surveyor-General, its role is to re-draw electorate boundaries to make sure each electorate has about the same number of people. Stats NZ calculates the general electoral population, number of general electorates, and North Island and South Island electoral quotas using the formulae specified in the Electoral Act 1993. When setting the boundaries, the Representation Commission also considers existing boundaries, communities of interest, the infrastructure that links communities (such as main roads), topographical features, and any projected variation in the population of those electorates during their existence.

​

Names are provided with tohutō/macrons (UTF-8 format). To support users with the compatibility of the data and the applications they might be using, additional fields are also provided in ASCII format.

​

The electoral populations are calculated from the 2023 Census data using the formulae specified in the Electoral Act 1993 and are confidentialised using Stats NZ confidentiality rules. The rules applied to the electoral populations are suppression of all unrounded counts below six (displayed as: ‘-999’) and random rounding to base three. There may be slight differences when comparing the total electoral population for electorates to totals derived using electoral population counts at meshblock level or another source.

​

In a small number of cases, the proposed electorate boundaries do not align to the annual 2025 meshblock boundaries exactly. This is due to meshblock adjustments that have been made as part of the Representation Commission’s process. Apart from these adjustments, a meshblock freeze remains in place until the Representation Commission has finished its electorate boundary review and the new electorate boundaries have been set.

Map layer featuring GB Parliamentary Constituency Boundaries. Created in February 2020 and data sourced from the ONS.

Legislative constituencies are the territorial framework for the election of each deputy to the National Assembly, deputies elected by direct universal suffrage for a renewable term of 5 years (unless the legislature is interrupted by a dissolution, article 24 of the Constitution). This division was seized by SIGU on the basis of documents sent by the prefecture through the election service of the City of Le Havre. A new division of the legislative districts of France was established by the two ordinances of 29 July 2009, ratified by the two Chambers on 19 and 21 January 2010, validated by the Constitutional Council on 18 February 2010, and published in the Official Journal on 23 February. The new electoral map has been in force since the 2012 parliamentary elections.

(Formally “District Electoral Divisions” (D.E.D.’s)) Under the 2001 Local Government Act, the names of Wards and the names of District Electoral Divisions are now changed to Electoral Divisions. There are 3,440 Electoral Divisions (EDs) which are the smallest legally defined administrative areas in the State. Electoral divisions are referred to by their established statutory names.Coordinate Reference System: Irish Transverse Mercator.This dataset is provided by Tailte Éireann
