Dernière mise à jour le : 24/05/2012

Présentation de l'opération

Organisme producteur :

Insee. Direction des statistiques démographiques et sociales (DSDS)

Type d'opération :

Administrative source

Objectifs :

The annual declaration of social data (DADS) is a declaration procedure which must be completed by all businesses that employ staff.

In this document, which serves both fiscal and social administrative purposes, employers provide certain information pertaining to their establishments and employees, annually and for every establishment.

For each employee the following information should be declared: the nature of the work and qualification, the starting and closing dates of the period of paid work, the number of paid hours, the terms of employment (full time, part time), the amount paid, etc.

For INSEE, details from DADS forms are used to produce statistics on wages and employment.

Thèmes abordés :

Themes covered:

- wages paid;

- employee descriptions.

Champ de l'opération

Champ géographique :


Champ(s) statistique(s) couvert(s) :

All employers and their employees are covered by the DADS declaration, except for employees of government bodies, whether incumbents or otherwise (legal categories beginning with 71, 7383, 7384 i.e. SIRET numbers beginning with 1 except those beginning 18 and certain other exceptions), domestic services (section 97-98 of NAF rev. 2) and businesses operating outside French territory (section 99 of NAF rev. 2).

However, local authorities and publically-employed hospital staff are included, having been comprehensively integrated into this scheme since 1992.

Public institutions of an industrial and commercial nature are also included.

For diffusion, data stemming from other sources are added to the data stemming from DADS to cover the whole field of the employment. The file so constituted is called "DADS-grand format".

Caractéristiques techniques

Unité statistique enquêtée :


Périodicité de l'opération :

Data from DADS forms are used by INSEE every year.

Data from a given year N are provisionally scheduled for publication in January of year N+2 for wage growth and the latter half of N+2 for detailed data.

Historique :

Since 1947, all employers have been required to fill in an administrative document detailing the periods of employment and wages of their employees.

This compulsory formality must be completed by all businesses with employees, in line with article R243-14 of the Social Security Code (Decree of March 24th 1972) and articles 87.240 and 241 of Law 51-711 of June 7th 1951 of the General Tax Code.

Since 1950 INSEE has been the official recipient of this form, and responsible for its statistical use. Initially, INSEE used tax documents on loan from the general tax inspectorate.

In 1970, these documents became the "annual wage declarations" (DAS). INSEE thereafter began to receive its own copy of the declaration.

In 1984 the DAS, combined with the attestation of paid activity (AAS), became the "declaration of social data" (DADS). Until 1991, INSEE used the information relating to employees (1 in 25 full time employees born in October in even years).

In 1992 a method for transmitting data using magnetic tape was gradually phased in ("social data transfer" or TDS).

In 1998, the National Commission for Computer Technology and Liberties (CNIL) granted INSEE authorisation to comprehensively use the DADS data and publish the results.

From 2005 the TDS standard was replaced by a new computerised format, the "unified annual declaration of social data", allowing businesses and regional authorities operating a wage software program capable of integrating this new norm to provide a single digital declaration.

Méthodologie :

Since 1993, DADS data has been used in a revamped manner, the principal advantage being that it allows for comprehensive processing of all employees.

In 2002, some methodological improvements were introduced.

Each DADS form received undergoes a number of processes, including:

- enhanced verification of the establishment's sector of activity and location of the employees declared on the DADS form;

- codification of the socio-professional category (PCS) and municipality of residence: this is an automatic coding of the profession headings provided 'in clear text' by the computerised coding systems for survey responses (the Sicore application) developed by INSEE. Failures in the automatic coding process (1 in 12 employees on average) are then partly manually processed;

- the general coherence of the DADS forms serves to confirm internal coherence (coherence of times, durations, pay figures, terms of employment).
