The first part of this book deals with the coverage of landline and mobile
phones in Europe. It presents an overview of the coverage and the use of phones
as well as the resulting strategies for telephone surveys. The second part
addresses the challenge of so-called mobile-only households for survey
research. Numerous statisticians present new sampling strategies like dual
frame designs and findings of current projects. In dual frame designs,
respondents are contacted both via mobile phone and landline. The third part
focuses on the usage of mobile phones in the general population, while the
fourth part of examines if different modes of data collection (mobile vs.
landline) have an impact on the response quality. The last part analyses the
first chapter and offers suggestions and advice on how to conduct surveys and
polls, in both academic and market research.
