3.1. Data description

The Structure of Earnings Survey (SES) provides EU-wide harmonised structural data on gross earnings, hours paid and annual days of paid holiday leave, which are collected every four years under Council Regulation (EC) No 530/1999 concerning structural statistics on earnings and on labour costs, and Commission Regulation (EC) No 1738/2005 amending Regulation (EC) No 1916/2000 as regards the definition and transmission of information on the structure of earnings. The objective of this legislation is to provide accurate and harmonised data on earnings in EU Member States and other countries for policy-making and research purposes.

The SES 2010 provides detailed and comparable information on relationships between the level of hourly, monthly and annual remuneration, personal characteristics of employees (sex, age, occupation, length of service, highest educational level attained, etc.) and their employer (economic activity, size and economic control of the enterprise).

Regional data is also available for some countries and regional metadata is identical to that provided for national data.

3.2. Classification system

The "economic activity" is coded in NACE Rev. 2 (General industrial classification of economic activities within the European Communities) whereas the "occupation" is coded according to the Commission Recommendation of 29 October 2009 on the use of the International Standard Classification of Occupations (ISCO-08).

Information on the 'Highest successfully completed level of education and training' variable is classified using the International Standard Classification of Education, 1997 version (ISCED 97).

Regional breakdown is based on the Nomenclature of Territorial Units for Statistics (NUTS) reference year 2010.

3.3. Coverage - sector

The statistics cover all economic activities defined in NACE Rev. 2 sections B to S. NACE Section O (Public administration and defence; compulsory social security) is optional, however covered by most countries.

The enterprises included employ at least 10 employees and the size classes (corresponding to the number of employees) available are 10 to 49, 50 to 249, 250 to 499, 500 to 999 and more than 1 000. The size class of enterprises employing less than 10 employees (1 to 9) is optional and covered by some countries.

3.4. Statistical concepts and definitions

Employees are all persons who have a direct employment contract with the enterprise or local unit and receive remuneration, irrespective of the type of work performed, the number of hours worked (full or part-time) and the duration of the contract (fixed or indefinite).

Mean annual gross earnings also cover all 'non-standard payments', i.e. payments not occurring in each pay period, such as: 13th or 14th month payments, holiday bonuses, quarterly or annual company bonuses and annual payments in kind.

Mean monthly gross earnings in the reference month cover remuneration in cash paid before any tax deductions and social security contributions payable by wage earners and retained by the employer, and are restricted to gross earnings which are paid in each pay period during the reference month.

Mean hourly gross earnings are defined as gross earnings in the reference month divided by the number of hours paid during the same period.

Number of hours paid includes all normal and overtime hours worked and remunerated by the employer during the reference month. Hours not worked but nevertheless paid are counted as 'paid hours' (e.g. for annual leave, public holidays, paid sick leave, paid vocational training, paid special leave, etc.).

3.5. Statistical unit

The compilation of structural statistics on earnings is based on local units and enterprises, as defined in Council Regulation (EEC) No 696/93, and provides information on employees in enterprises with 10 or more employees classified by size and economic activity. Information for employees in enterprises with fewer than 10 employees is optional.

The statistics cover all activities defined in NACE Rev. 2 sections B to S (excluding O) for enterprises with at least 10 employees.

3.6. Statistical population

The SES 2010 statistics refer to enterprises with at least 10 employees in the areas of economic activities defined by NACE Rev. 2 sections B to S excluding O.


The inclusion of NACE section O is optional, as well as the inclusion of enterprises with less than 10 employees. 

3.7. Reference area

The data cover EU-Member States and Candidate Countries and European Free Trade Association (EFTA) countries.

3.8. Coverage - Time


3.9. Base period

Not applicable.

4. Unit of measureTop

Euro (EUR), Purchasing Power Standard (PPS) and Percentage (%).

5. Reference PeriodTop

The reference year is equal to the calendar year (2010).

Some countries provide data according to the financial year which might deviate from the calendar year. For these countries, the financial year which gives the best match with the calendar year 2010 was used.

The reference month is October for the majority of the countries. The choice of another month is accepted as long as the month is justified as being representative.

6. Institutional MandateTop
6.1. Institutional Mandate - legal acts and other agreements

EU-Member States and (if available and comparable) other European countries participating in the four-yearly Structure of Earnings Survey according to the;

Council Regulation (EC) No 530/1999 of 9 March 1999 concerning structural statistics on earnings and on labour costs; 

Commission Regulation (EC) No 1738/2005 of 21 October 2005 amending Regulation (EC) No 1916/2000 as regards the definition and transmission of information on the structure of earnings; 

Commission Regulation (EC) No 72/2002 of 16 January 2002 implementing Council Regulation (EC) No 530/1999 as regards quality evaluation of structural statistics on earnings. 

Regional data according to Commission Regulation (EC) 1059/2003

6.2. Institutional Mandate - data sharing

Not applicable.

7. ConfidentialityTop
7.1. Confidentiality - policy

Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society.

7.2. Confidentiality - data treatment

In the SES, information about individual entities (employees and enterprises) is collected. The safety of these microdata has to be guaranteed to make sure that individual entities cannot be recognised through inspection of released data. The goal of disclosure control is to disseminate statistical information in such a way that individual information is sufficiently protected against recognition of the subjects to which it refers, while at the same time providing as much information as possible.

Only tabular data have therefore been published. In order to limit the disclosure risk of these tables the following measures have been applied:

  • Region: restricted to the national level;
  • Economic activity: restricted to NACE Rev. 2, one digit level;
  • Size of the enterprise: published in size classes of employee numbers;
  • Age: restricted to 5 size classes (less than 30 years, 30-39 years, 40-49 years, 50-59 years, 60+ years);
  • Occupation published at ISCO-08, one digit level.

The anonymisation method for SES consists of two primary confidentiality rules:

- minimum frequency rule;

- dominance rule

Secondary confidentiality rules are applied as additional protection to protect data from recalculation.

20. Statistical processingTop
20.1. Source data

The data collection for LCS and SES can be obtained from 'tailor-made' questionnaires, existing surveys, administrative data or a combination of such sources, which provide the equivalent information. While accepting a degree of flexibility in the means employed for collecting the survey data, the information obtained must be of acceptable quality and be comparable between European countries.

20.2. Frequency of data collection


20.3. Data collection

The national surveys are generally conducted on the basis of a two-stage random sampling approach of enterprises or local units (first stage) and employees (second stage).

20.4. Data validation

Data validation consists of global checks and plausibility checks. Global checks are necessary to ensure that complete data is received for microdata records. For each country, all microdata records should contain data for all mandatory variables. Missing mandatory data or codes are not accepted. Concerning optional variables each country decides which of these it is able to supply. Furthermore, plausibility checks on all variables were done to ensure that the data are reasonable and consistent with other variables. Possible deviations are reported by countries in their national Quality Report transmitted to Eurostat. For further details on the plausibility checks implemented by Eurostat are provided in the implementing arrangements document which is approved and sent to all countries prior to each round (Validation level 2).
