ECS 2013 – Weighting

To allow for appropriate generalisations based on the survey results, the following weights have been constructed for the 3rd ECS:

• Establishment proportional weights - each establishment has been assigned a sampling weight, which reflects the number of establishments in the frame population, represented by the establishment itself.
• Employee proportional weights - the employee-proportional weights reflect the number of employees in the working population that are represented by the establishment. It is self-referential, relating the answers to the survey question ‘How many employees work in this establishment?’, to the information on the distribution of workers that is available from Eurostat’s Labour Force Survey (or related sources).
