International Territorial Levels
International Territorial Levels (ITLs) are the UK’s system for dividing regions into three statistical levels: ITL1, ITL2, and ITL3. They provide a consistent framework for analysing data, comparing regions, and supporting decision-making across government, business, and research.

International Territorial Levels (ITLs) are the official system used in the United Kingdom to define regions for statistical and analytical purposes. Introduced by the Office for National Statistics (ONS) in 2021, ITLs replaced the European Union’s Nomenclature of Units for Territorial Statistics (NUTS) following Brexit, ensuring that regional data could continue to be collected and compared consistently.
