The same revision policy is applied to STS data released nationally and transmitted to Eurostat.

All revisions are taken into account.

Routine revisions are mainly due to late administrative déclarations (< 1% of the total declarants) which result in revisions for the last two months published .

Then SA-WDA data are also revised each month as a consequence of the new calculation of SA-WDA coefficients. These revisions are taken into account each month.

Major revisions are mainly due to rebasing, new weights or update of productivity factors.

No revision calendar exists.

Warnings are published in the national publication "Informations Rapides" and on the web site www.insee.fr when the revisions are major revisions like after rebasing or changes in methodology.

In the whole construction, the mean revision between january 2021 and december 2023 is 1.07 point for the year-on-year growth rate of the calendar adjusted serie (see below).

In the whole construction, the mean absolute revision between january 2021 and december 2023 is 1.85 point for the year-on-year growth rate of the calendar adjusted serie (see below).

These revisions include the impacts of rebasing or major methodological changes.

Revisions in the whole construction between january 2021 and december 2023 (36 months)

MR = 1.07 and MAR = 1.85

Rebasing and reference change

The 2015 rebasing implemented an important innovation, with the introduction of annually chained indices instead of fixed-weights indices.
