59th Conference of European Statisticians (CES), 14 June 2011, Geneva Questions for the authors Question for The Netherlands Activities for social and business surveys are combined in data collection. Could you tell something about clear differences between these kind of surveys and how these differences are being treated? Question for Sweden The structure of the data collection departments and units is based on the collection mode and type of respondents. Can you tell us more about the different approach for social and business surveys? 8

59th Conference of European Statisticians (CES), 14 June 2011, Geneva Questions for the authors (2) Question for Sweden The Dutch paper mentions a general data collection strategy.

59th Conference of European Statisticians (CES), 14 June 2011, Geneva Questions for authors and audience The use of mixed mode surveys seems to stimulate the centralization of data collection activities. The papers do not discuss the use of mixed sources (combine data from administrative sources and surveys) 1.Can you give an indication if and how the use of mixed sources affect the organization of data collection? 2.Are there examples where the use of mixed sources has lead to a change in the organization of data collection and can you give an explanation how? 10

59th Conference of European Statisticians (CES), 14 June 2011, Geneva Questions for authors and audience (2) Both papers say that centralization of data collection activities creates a tension between data collection and subject matter units. Let us take into account the need for reducing the response burden. 1.Does this affect the organisation of data collection? → answer by The Netherlands → reaction of the audience 11

59th Conference of European Statisticians (CES), 14 June 2011, Geneva Conclusions Very useful and interesting papers Centralization of data collection activities can contribute to: Cost reduction Effective collection strategy Reduction of response burden Attention should be given to the relationship between data collection and subject matter 12
