The Structure of Earnings Statistics (SES) aims to report on earnings, the occupation and the attained education level of employees. Micro enterprises, employing less than 10 persons, are excluded from the reference frame. A primary sample includes local units of enterprises whereby a stratified sampling scheme is used. Finally employees are sampled among the selected establishments. The individual inclusion probability for employees is range bound by tuning their required number to the selection probability of the local unit. Very small establishments are drawn with a low probability, yet all employees are selected. An exhaustive survey for large establishments requires a relatively limited sample of employees. Individual employee remuneration and data on working time will now be retrieved from administrative social security data, recently made available. In this mixed-mode data collection, establishments only need to report on some personal characteristics of their workers, like their occupation and education level attained. This information is available at the human resources unit of the employer and they do not need to source in financial data on remuneration. Since the payroll often is managed by an external social secretariat, the reform implies that the involvement of a third party and the corresponding additional cost for the respondent no longer is required. Both the significantly reduced response burden and the simplified survey questionnaire (from 25 down to 5 variables) should contribute to a much lower non-response.
