Description
|
The four-yearly Structure of Earning Survey (RCL-SES) covers both the population of Private Companies and Institutions and Public Institutions, in the non-agricultural sectors (NACE rev.2 sections B to S), with at least 10 employees.
The collection is governed by Council Regulation 530/99, European Commission Regulation 1738/2005 and Commission Regulation 698/06 on quality evaluation of statistics on labour costs and structure of earnings.
It follows harmonised collection criteria and standards shared with all European Union countries. This allows a high degree of comparability of results.
It offers important evidence on existing wage differentials in the national labour market and its segments related to personal and professional characteristics of workers (gender, age, educational qualification, professional qualification).
Data are also presented with reference to the structural characteristics of enterprises (economic activity, geographical location, company size).
Several methods have been adopted for the data collection: a direct survey assisted by the use of administrative data for the private sector, and the direct use of administrative data from different sources for the public sector.
The survey sample includes about 24,000 enterprises and about 248,000 employees. The survey involves the total number of enterprises with 250 employees and more, and a sample of enterprises with between 10 and 249 employees. The survey unit is the enterprise, while the analysis units are both the enterprise and the individual employee.
