1. International Territorial Levels (ITLs)

To distinguish the replacement UK classification from its EU predecessor, the UK-managed classification is referred to as International Territorial Levels (ITLs) and adopts a convention used by the Organisation for Economic Co-operation and Development (OECD) member countries. These ITLs therefore align with international standards, enabling comparability internationally.

The ITLs have been established as a mirror to the previous Eurostat NUTS system used by the UK and will follow a similar timetable to the review of the NUTS system, meaning ITLs will be reviewed every three years.
