Eurobarometer Data Service

Sampling and fieldwork

For each Flash Eurobarometer new and independent samples are drawn by random. Representativity is stated for the respective universe. Selection details (e.g. RDD, regions quotas, ...) for the total population (15+) and the youth surveys are not published.

In the case of the MANAGER (top level executive) surveys, the target type(s) of business are defined by size of company groupings and activity sector. Within each of the cells defined by these criteria, the selection of the sample units was made at random. The samples are drawn from lists of companies qualified to be interviewed provided by Dun & Bradstreet.

Other specific professional groups are exactly defined and randomly selected from lists of potential interview partners, if necessary in a two stage process, first starting from full lists of relevant institutions.
