Workshop on mixed-mode surveys: benefits and pitfalls

Mixed-mode surveys that is, surveys combining several modes of data collection, have been gaining more and more importance among data producers. The implementation of such surveys offers strong advantages to statistical organisations, while at the same time key methodological questions must also be carefully examined.

That’s why STATEC, in collaboration with the Observatory for Competitiveness of the Ministry of Economy and the support from the Luxembourg Statistical Society, is organising a workshop on mixed-mode surveys to gather experts in this field of study. The main goals of this event are:

  • To promote the use of mixed-mode surveys within Luxembourg’s National Statistical System as a way both to increase survey participation and reduce costs;
  • To discuss the main challenges ahead in relation to the development and implementation of mixed-mode surveys;
  • To build synergies with other statistical organisations within Luxembourg and in Europe.
