Ireland uses the Nomenclature of Territorial Units for Statistics (NUTS) geocode standard for referencing country subdivisions for statistical purposes.^[1] The standard is developed and regulated by the European Union. The NUTS standard is instrumental in delivering European Structural and Investment Funds. The NUTS code for Ireland is IE and a hierarchy of three levels is established by Eurostat. A further level of geographic organisation, the local administrative unit (LAU), in Ireland is the local electoral area.

The most recent revision of NUTS regions was made in 2016 and took effect in 2018.^[2] The eligibility of regions for funding under the European Regional Development Fund and the European Social Fund Plus was revised in 2021. NUTS 2 Regions may be classified as less developed regions, transition regions, or more developed regions.^[3]

The local administrative units in Ireland are the local electoral areas.^[5] These are subdivisions of local government areas used for local elections. In counties outside Dublin and in the cities and counties, they also form the basis of municipal districts within local authorities.

Each of the three NUTS 2 regions has a Regional Assembly. These are divided into strategic planning areas, which correspond to the NUTS 3 regions. Prior to 2014, the eight NUTS 3 regions had Regional Authorities. The 2014 act abolished these and transferred their functions to the Regional Assemblies.^[6] Assembly members are nominated by constituent local authorities from among their elected councillors.
