Non-Response in Probability Sample Surveys in the Czech Republic

In this article the problem of survey non-response is examined with special reference to probability sampling in the Czech Republic. Non-response rates among Czech respondents in ISSP surveys between 1995 and 2005 were almost twice the rate recorded between 1991 and 1995 (25%). Such trends point to a decline in the ‘survey climate’. While non-contacts and refusals in surveys are a signifi cant problem, issues relating to how fi eldwork is undertaken are equally important. The large fl uctuations in non-contact rates and the relative success of the Czech Statistical Offi ce in attenuating non-response rates demonstrates that prudent surveying strategies can be effective. An examination of two waves of the European Social Survey (ESS) reveals both the problems and potential strategies available for response rate enhancement. In this respect, all survey designers face the dilemma of balancing the benefits of data accuracy with increasing logistical costs. Improvement in survey quality necessitates consideration of many issues and the ability to make sensible trade-offs between competing research objectives.
