Following Brexit, the ONS set to develop a domestic statistical classification framework separate from NUTS. Currently, the ITLs are a mirror to the pre-existing NUTS system, they retain the same three level hierarchy and boundaries used for NUTS in the United Kingdom since 2018, with the next review scheduled for 2024. ITLs are set to follow a similar review timetable to NUTS, being reviewed every three years. The ONS will develop new official GSS codes of ITL geography aligned with the existing NUTS codes. From 1 January 2021, the ONS encourages "ITL" be used as a replacement to the "NUTS" designation, with lookups between NUTS and ITL maintained and published until 2023.[1][2]
The current ITL classification is a mirror of the previous NUTS classification with slight modification, the ONS lists 12 regions at ITL 1, 41 regions at ITL 2, and 179 regions at ITL 3.[1] "UK" in the NUTS codes were replaced with "TL".
The last NUTS classification is dated 21 November 2016 and was effective from 1 January 2018, listed 12 regions at NUTS 1, 40 regions at NUTS 2, and 174 regions at NUTS 3 level.
The 12 ITL regions of the United Kingdom are listed below. Population numbers are for mid-2019 (as NUTS 1), and areas are in square kilometres. Data is from the Office for National Statistics.[3]
In the first version in 2003, North Eastern Scotland (which then included part of Moray) was coded UKM1, and Highlands and Islands was coded UKM4.
The current NUTS level 1 codes start with "C" (following "UK") rather than "1" because the new list reflected the revised regions of England and local government changes throughout the UK; "1" to "B" had been used for the 11 regions in the previous coding system.
2010 changes to NUTS 2 also resulting in changes with NUTS 3 regions
The combined area of UKD2 (Cheshire pre-2010) and UKD5 (Merseyside pre-2010) were replaced by UKD6 (Cheshire post-2010) and UKD7 (Merseyside post-2010), due to the transfer of Halton to the Merseyside NUTS region from Cheshire. This resulted in the following changes to the underlying NUTS 3 areas: UKD22 (Cheshire CC) being split into UKD62 (Cheshire East) and UKD63 (Cheshire West and Chester); The areas of Liverpool, Sefton and Wirral were not changed as NUTS 3 areas however to reflect their transfer within NUTS 2 areas were respectively renumbered from (UKD52 to UKD72; UKD53 to UKD 73 and UKD54 to UKD 74). The two areas of UKD51 (East Merseyside pre 2010) and UKD21 (Halton and Warrington) were amended by the transfer of Halton from the latter to former to form the new areas of UKD71 (East Merseyside post-2010) and UKD61 (Warrington).

ITL 2021
Following Brexit, the classification used by the ONS was replaced with ITLs. Between 2021 and the next review scheduled for 2024, the ITLs are a mirror of the NUTS classification adopted in 2018. All NUTS codes containing "UK" were changed to use "TL" for Territorial Level.
Parts of this article (those related to since 2017 only one LAU-level with 383 units) need to be updated. Please help update this article to reflect recent events or newly available information.(December 2023)
Below the ITL levels, the two LAU (Local Administrative Units) levels are:
North West England is one of nine official regions of England and consists of the ceremonial counties of Cheshire, Cumbria, Greater Manchester, Lancashire and Merseyside. The North West had a population of 7,417,397 in 2021. It is the third-most-populated region in the United Kingdom, after the South East and Greater London. The largest settlements are Manchester and Liverpool.
Metropolitan counties are a subdivision of England which were originally used for local government. There are six metropolitan counties: Greater Manchester, Merseyside, South Yorkshire, Tyne and Wear, West Midlands and West Yorkshire.
The administrative geography of the United Kingdom is complex, multi-layered and non-uniform. The United Kingdom, a sovereign state to the northwest of continental Europe, consists of England, Northern Ireland, Scotland and Wales. For local government in the United Kingdom, England, Northern Ireland, Scotland and Wales each have their own system of administrative and geographic demarcation. Consequently, there is "no common stratum of administrative unit encompassing the United Kingdom".
Nomenclature of Territorial Units for Statistics or NUTS is a geocode standard for referencing the administrative divisions of countries for statistical purposes. The standard, adopted in 2003, is developed and regulated by the European Union, and thus only covers the EU member states in detail. The Nomenclature of Territorial Units for Statistics is instrumental in the European Union's Structural Funds and Cohesion Fund delivery mechanisms and for locating the area where goods and services subject to European public procurement legislation are to be delivered.
A Scout County is an administrative division within The Scout Association of the United Kingdom. There are currently 115 Counties and Areas in the United Kingdom. These bodies are responsible for providing programmes and support for their member Scout Districts.
The Parliament of the United Kingdom currently has 650 parliamentary constituencies across the constituent countries, each electing a single member of parliament (MP) to the House of Commons by the plurality voting system, ordinarily every five years. Voting last took place in all 650 of those constituencies at the United Kingdom general election on 12 December 2019.
England is divided by a number of different regional schemes for various purposes. Since the creation of the Government Office Regions in 1994 and their adoption for statistical purposes in 1999, some historical regional schemes have become obsolete. However, many alternative regional designations also exist and continue to be widely used.
The NUTS codes of Hungary have three levels:
The WA postcode area, also known as the Warrington postcode area, is a group of sixteen postcode districts in North West England, within nine post towns. These cover north Cheshire, eastern Merseyside and small parts of south-western Greater Manchester.
The demography of Greater Manchester is analysed by the Office for National Statistics and data is produced for each of its ten metropolitan boroughs, each of the Greater Manchester electoral wards, the NUTS3 statistical sub-regions, each of the Parliamentary constituencies in Greater Manchester, the 15 civil parishes in Greater Manchester, and for all of Greater Manchester as a whole; the latter of which had a population of 2,682,500 at the 2011 UK census. Additionally, data is produced for the Greater Manchester Urban Area. Statistical information is produced about the size and geographical breakdown of the population, the number of people entering and leaving country and the number of people in each demographic subgroup.
The Nomenclature of Territorial Units for Statistics (NUTS) is a geocode standard for referencing the subdivisions of Bulgaria for statistical purposes. The standard is developed and regulated by the European Union. The NUTS standard is instrumental in delivering the European Union's Structural Funds. The NUTS code for Bulgaria is BG and a hierarchy of three levels is established by Eurostat. Below these is a further levels of geographic organisation - the local administrative unit (LAU). In Bulgaria, the LAU 1 is municipalities and the LAU 2 is settlements.
The Nomenclature of Territorial Units for Statistics (NUTS) is a geocode standard for referencing the subdivisions of Switzerland for statistical purposes. As a member of EFTA Switzerland is included in the NUTS standard, although the standard is developed and regulated by the European Union, an organization that Switzerland does not belong to. The NUTS standard is instrumental in delivering the European Union's Structural Funds. The NUTS code for Switzerland is CH and a hierarchy of three levels is established by Eurostat. Below these is a further levels of geographic organisation - the local administrative unit (LAU). In Switzerland, the LAUs are districts (LAU-1) and municipalities (LAU-2).
The regions of England, formerly known as the government office regions, are the highest tier of sub-national division in England. They were established in 1994 and follow the 1974–96 county borders. They are a continuation of the former 1940s standard regions which followed the 1889–1974 administrative county borders. Between 1994 and 2011, all nine regions had partly devolved functions; they no longer fulfil this role, continuing to be used for limited statistical purposes.
The Nomenclature of Territorial Units for Statistics (NUTS) is a geocode standard for referencing the subdivisions of Germany for statistical purposes. The standard is developed and regulated by the European Union. The NUTS standard is instrumental in delivering the European Union's Structural Funds. The NUTS code for Germany is DE and a hierarchy of three levels is established by Eurostat. Below these is a further levels of geographic organisation – the local administrative unit (LAU). In Germany the LAUs 1 is collective municipalities, and the LAU 2 is municipalities.
As a candidate country of the European Union, North Macedonia (MK) is included in the Nomenclature of Territorial Units for Statistics (NUTS). The three NUTS levels are:
As a candidate country of the European Union, Turkey (TR) is included in the Nomenclature of Territorial Units for Statistics (NUTS). Defined in 2002 in agreement between Eurostat and the Turkish authorities, Turkey's NUTS classifications are officially termed statistical regions, as Turkey is not a member of the EU and Eurostat only defines NUTS for member states. The three NUTS levels are:
International Territorial Level (ITL) is a geocode standard for referencing the subdivisions of the United Kingdom for statistical purposes, used by the Office for National Statistics (ONS). Between 2003 and 2021, as part of the European Union and European Statistical System, the geocode standard used for the United Kingdom were Nomenclature of Territorial Units for Statistics or NUTS. The NUTS code for the UK was UK and the NUTS standard had a hierarchy of three levels, with 12 first level regions, which are currently mirrored by the ITL classification, of which 9 regions are in England. The sub-structure corresponds to administrative divisions within the country. Formerly, the further NUTS divisions IV and V existed; these have now been replaced by Local Administrative Units . Between 1994 and 2011, the nine regions had an administrative role in the implementation of UK Government policy, and as the areas covered by elected bodies.
West Wales and the Valleys is a UK International Territorial Level 2 statistical region covering the western areas of Wales and the South Wales Valleys. Created as part of the Eurostat's Nomenclature of Territorial Units for Statistics (NUTS), it was used to by the European Union (EU) to deliver the European Regional Development Fund to areas of Wales, until the UK's withdrawal from the EU in 2020. Following which it was mirrored onto the Office for National Statistics' International Territorial Level (ITL) geoclassification system. The remainder of Wales is part of the East Wales statistical region.
