Zone d'études et d'aménagement du territoire
In 1967 the Institut national de la statistique et des études économiques, together with the French Commissariat général and DATAR declared the nominal division of France into eight large regions. These were named Zones d'études et d'aménagement du territoire or ZEAT.
Until the end of 2017, the ZEAT corresponded to the first level in the European Union Nomenclature of Territorial Units for Statistics.
