Insee revises the values of its statistics to reflect reality as accurately as possible and to ensure their relevance and reliability. It uses well-established, standardised and planned procedures according to international standards. It announces revisions simultaneously with their release or in advance according to a protocol adapted to the source of the revisions, their magnitude and the sensitivity of the published statistics. All the explanations necessary for understanding these revisions accompany the release of the statistical sources concerned on the insee.fr website.

The first results published in July 2022 will be revised in the first quarter of 2023 following changes to the weightings.
