The deadline for the transmission of basic data from NSIs to Eurostat is at the moment T + 12, for NUTS 2 data for total Value Added, total employment and population, and T + 24 months, for all the other data.

The data are published on insee.fr after transmission to Eurostat in January.

The sources required to prepare the accounts are collected and compiled on an ongoing basis, starting in the summer. The latest data received and required to prepare all regional accounts are the accounts of the overseas territories, as of September 30.

Since 2025, as part of the benchmark revision, the estimation methodology for the provisional account has been improved. In particular it uses a source available earlier in the year, which should allow for more data quality checks and ultimately align the publication on insee.fr with the transmission to Eurostat.

The data are transmitted to Eurostat within the legal deadline and published within the following weeks on insee.fr.

This data should coincide with the transmission to Eurostat in the coming years.
