Objectifs :

The quarterly survey on labour activity and employment conditions (Acemo) measures trends in basic wages, which is useful for monitoring the overall outlook for wages and for indexing the minimum wage (SMIC).

Its purpose is also to measure trends in working hours and fluctuations in the short term, also whether or not there are difficulties with hiring and the number of vacant posts.

Three main indices are calculated on the basis of the quarterly Acemo survey:

- trends in a worker's basic hourly wage (SHBO);

- trends in the basic monthly wage (SMB) by socio-professional category (worker, employee, intermediate profession and manager);

- index of hourly labour cost - all employees (ICHTrev-TS).

Along with data from Urssaf, Unedic and DADS, this survey is one of the sources used to calculate quarterly employment estimates. It also provides the proportion of employees working part-time and those with fixed-term contracts.

Périodicité de l'opération :


Période et mode de collecte :

Data are collected by mail delivery at the end of each quarter.

Historique :

The quarterly Acemo survey was launched in 1946.

The survey in its present form was conducted for the first time in January 2006 after a fundamental overhaul by DARES in collaboration with Insee and the social partners involved.

Plan de sondage :

The survey is conducted on about 34,000 establishments belonging to an enterprise of 10 employees or more.

Establishments of 250 employees or more are surveyed exhaustively.

Those with less than 250 employees are surveyed, with a quarter of the sample being renewed every year.

Méthodologie :

Every quarter, the ACEMO survey measures change in the basic monthly wage (SMB) of all employees in enterprises in Metropolitan France with ten or more employees in the non-agricultural competitive sector.

The basic monthly wage (SMB) includes neither bonuses (except, as applies, the bonus linked to the reduction in working hours) nor overtime. It is a gross wage before social contributions are deducted and before social benefits are paid. This usually corresponds to the amount on the first line of the employee's wage slip.

The ACEMO survey measures changes in the basic hourly wage of a worker (SHBO) every quarter in firms with 10 employees or more in the non-agricultural competitive sector in Metropolitan France.

The basic hourly wage of a worker (SHBO) includes neither bonuses (except, as applies, the bonus linked to the reduction of working hours) nor overtime. It is a gross wage before social contributions are deducted and before social benefits are paid. It is measured only for the population of blue collar workers.

In the ACEMO survey, this is obtained by dividing the gross monthly wage (generally to be found on the first line of the wage slip) by the employee's basic monthly working hours, calculated as an average across the year (for an employee working 38 hours per week and with 23 days for reduced working time (RTT), average weekly working hours across the year are 35 hours and the basic monthly working hours are 152 hours).

Autres spécifications :

The other Acemo surveys:

These also concern the competitive sector excluding agriculture.

- Acemo survey on micro-enterprises: conducted every year on 60,000 enterprises with between 1 and 9 employees, the aim is to complete the quarterly Acemo survey once a year and thus calculate different indicators according to the sector of activity of the enterprise, the socio-professional category of the employees, their gender or age.

In particular, it provides the percentage of employees paid the minimum wage (SMIC) in economic activities (measured at the enterprise level);

- Acemo survey on negotiation and employee representation: conducted every year on about 10,000 enterprises in Metropolitan France, the aim is to provide major indicators concerning negotiations held in enterprises, their content and the agreements reached, the presence of institutions representing employees from the enterprise and different trade union organisations, the occurrence of collective work stoppages, the reasons for these and the number of individual days not worked in the course of the year;

- Acemo survey on the share of employees covered by works agreements: conducted every year on 10,000 establishments in Metropolitan France which belong to an enterprise of 10 employees or more, it aims to measure branch-level collective agreement coverage in establishments  and among employees, to attribute a main works agreement code to establishments in the quarterly survey sample and define key jobs to be used for monitoring basic wages in the quarterly survey;

- Acemo survey on shares, profit-sharing, company savings plans and employee shareholding (Pipa): conducted every year on about 17,000 enterprises of 10 employees or more, this survey provides better knowledge of the behaviour and practices of enterprises in terms of profit-sharing (number of employees covered by agreements, categories of agreement, amounts distributed, existence and composition of a company savings plan, etc.);

- Acemo survey on the organisation of working time: conducted occasionally on about 10,000 enterprises, the aim of this survey is to measure changes brought about by reforms in arrangements to organise working time in terms of hours and how these are carried out in enterprises, and to assess time management practices;

- Acemo survey specifically on wage practices: conducted occasionally on about 10,000 enterprises of 10 employees or more, the aim of this survey is to provide an overview of all company wage practices, in the context of increasingly frequent arrangements to provide individualised wages, to reward performance or provide extra social protection.
