Type: Book chapter
The European Social Survey (ESS), a biennial face-to-face survey on values, attitudes, opinions and beliefs in more than 30 countries, specifies a target response rate of 70%. Despite great efforts by participating countries, this target is out of reach for many, and response rates vary across countries and over time. Several studies have shown that there is no straightforward relationship between response rates and nonresponse bias. The presence and size of nonresponse bias is especially hard to assess in a study on values and attitudes where no external evidence is available on population outcomes. Different types of auxiliary variables and paradata have been used to identify potential nonresponse bias: population statistics, interviewer observations of neighbourhood and dwelling, information from doorstep questionnaires to refusals and follow-up studies among respondents and nonrespondents, and information derived from contact forms and detailed call schedules. This paper will give some basic information on the ESS, outline response enhancing efforts, and give an overview of different strategies to estimate and correct for nonresponse bias. It will also discuss the present focus on overall response rates and alternative approaches for reducing nonresponse bias.
