_Warning (10/06/2021)_: The introduction since March 2015 of the Nominal Social Declaration (DSN), which replaces, inter alia, the Contribution Summary Schedule (BRC), modifies the reporting information necessary for the calculation of the statistical indicators presented in this publication. The new source makes it possible to calculate the number of staff of institutions on the basis of individual contract data, whereas the aggregate staff of the same institutions, historically present in the BRCs, remained transiently present in DSN. The integration of individual data into the chain of statistical processing of employees, which has been carried out gradually since 2016, was finalised in June 2021 with the publication of the results for the first quarter of 2021. More significant than usual revisions, especially at levels, can therefore be observed on staffing compared to the publication for the last quarter of 2020. The workforce data are now 100 % of the exploitation of the individual data of the DSN (see [Acoss Stat 325](https://www.urssaf.org/home/observatoire-economique/publications/acoss-stat/2021/acoss-stat-n325.html)).
