Objectifs :

The purpose of the labour cost and structure of earnings survey (Ecmoss) is to monitor on an annual basis the structure of employee earnings and working time.

In addition, it provides information on both:

- elements to account for disparities in earnings, this is the "structure of earnings" or "SES" section of Ecmoss;
- measuring and breaking down the labour costs for employers, this is the "labour cost" or "LCS" section of Ecmoss.

It complements the Annual Declaration of Social Data (DADS). This survey meets the demand for harmonisation across all countries of the European Union, so that comparative analyses and structural statistics can be drawn up.

Période et mode de collecte :

Data is collected from May to December, by post.

Historique :

The framework of European Regulation no. 530/1999 of 9 March 1999 set the periodicity of the labour cost survey (LCS) and of the structure of earningssurvey (SES) which have since been carried out periodically.

These two surveys are now conducted in each country every four years (one at 2-yearly intervals).

The purpose of the LCS survey is to produce an average annual labour cost per employee and an average hourly labour cost per hour actually worked.

The SES survey provides data about wages, their component parts (gross wage, bonuses, overtime payment), determining factors (diploma, qualification, professional experience) and the occupied shift (sector activity, size of company, region, actual working hours, occupation, nature of contract).

In order to rationalise the survey process, lighten the burden for companies responding to the questionnaire and still meet the European requirements, France decided to coordinate the production of surveys dealing with these subjects.

The LSC, the SES and the annual Acemo survey (conducted by the Research, studies and statistics department - Dares - of the Ministry for Labour) were combined, and this gave rise to the first Ecmoss survey, launched in 2006 (using data relating to 2005).

The Ecmoss survey has since been annual.

The majority of the questions on the employee questionnaire appear every year. In addition, in the "SES" years, the employee questionnaire requires some additional individual information.

The local unit questionnaire looks at wage policies and employee representation.

In the "LCS" years, the employee questionnaire contains only questions that are relevant to the year in question, as the local unit questionnaire provides item by item details of the costs involved in employing workers.

A complete survey cycle lasts four years : two consecutive years with the "SES" format with the Ecmoss 2005 and Ecmoss 2006 surveys as starting point, followed by two "LCS" years, i.e. Ecmoss 2007 and Ecmoss 2008.

Plan de sondage :

The sample selection process is based on a two stages sampling design, with first a choice of local units (selected in the French administrative business register Sirene) then, with a selection of employees within the local units selected in first stage (via DADS).

Ecmoss samples for successive years are negatively correlated, to avoid re-interviewing the same local units two years running.

The survey is conducted on a sample of about 17,000 local units which form part of a company with more than 10 employees, and a sample of 150,000 employees.
