NOGA revision

In order for the classifications of economic activities to correspond to reality (creation, decline and disappearance of activities over time), it is necessary to update them. Furthermore, with the aim of ensuring the international comparability of statistics, the associated revision processes are carried out in a concerted and coordinated manner between the various user countries.

In 2019, the Statistical Office of the European Union (Eurostat) has launched the revision of NACE. At the same time, the FSO has also decided to launch a revision process of the NOGA. In March 2021, the United Nations Statistical Office (UNSD) formalized the process of revising the International Standard Industrial Classification of all Economic Activities (ISIC).  

In May 2022, the new NACE structure (NACE Rev. 2.1) was validated by the European Statistical System Committee (ESSC). Following this validation, the Swiss Federal Statistical Office's Nomenclatures Domain drew up a preliminary version of the new NOGA structure (NOGA 2025). This was submitted to the various revision partners in September 2022 for comment.

Based on this feedback, a first version of the NOGA 2025 was created, and a national consultation was launched in June 2023. The results of the latter led to minor adaptations to the structure.

The final version of the NOGA 2025 was submitted to Eurostat in March 2024 and officially validated in April 2024. Work is now focused on introducing NOGA 2025 into statistical production. Initially, with the recoding of units in the Business and Enterprise Register (BER), then, from 2026 onwards, with the phased introduction of NOGA 2025 into the statistics produced by the FSO.
