In December 2014, Dalia partnered with some of the world’s leading market research institutes, online panel providers and think tanks to explore the scope and limits of real-time mobile sampling. This report provides an overview and analysis of the research project, which covered 28 EU countries. To better understand fieldwork dynamics, user behaviour, completion rates, demographic reach and other elements, Dalia Research invited a census-representative sample of over 20.000 European smartphone users below the age of 40 to answer a questionnaire with approximately 100 question items. The survey was conducted across a network of several thousand apps and mobile websites. The project generated a total of over 4 million answers on topics ranging from brand perception to food labelling, political attitudes, online shopping behaviour and other areas of interest. With the exception of Cyprus, real-time mobile sampling was found to be a viable method to reach a large pool of casual mobile respondents across Europe for market and opinion research.
