RICA commissioned Deakin University to “establish whether response rates are in decline in the Australian market research industry and to identify, as far as possible, the reasons for these declines if they exist. This is likely to involve a review of previous research, a literature review and collection of data on response rates provided on a confidential basis and with the assistance of AMSRO to facilitate data provision.”
Attempts were made to contact all listed market research companies in Australia, including all major internet panel companies. While industry co-operation was not high with the study, sufficient data was provided to depict current response rates and to show how they had declined over time. Because of the low contactability issues, this Report proposes the use of better methods to compute the reliability of survey estimates by taking account of past survey results.
The literature review revealed a wealth of recent studies, with the main emphasis being on studies of telephone and internet surveys. This review of the research produced 34 evidence-based guidelines for social researchers. While some of these reflect current practice, the emergence of the internet as the main survey method raises a number of disclosure and sampling issues. Esomar (2012) has produced 28 issues to be raised with providers, which sets the basis for good industry practice. This suggests an opportunity for the industry to adopt these standards as its own and to conduct training courses for major clients and suppliers. There are many panel providers, some of whom are not AMSRO members. AMSRO may need to examine what role it can play in mandating or encouraging adherence to these standards as a way of promoting the industry.
Talks with key industry people, as well as the literature, have revealed the importance of blended surveys, where multiple contact and response mechanisms are used. Particularly where an internet panel is used as one source, this poses representativeness and weighting issues which are difficult to resolve. The Report recommends that where blended survey methods are used, measures be taken to measure contactability in the other contact media, along with more sophisticated weighting schemes. The industry should examine its training courses to ensure that industry expertise keeps pace with these developments. Summary of Results
The results focus on two main collection methods – the telephone and the internet. As far as the telephone is concerned response rates have been in a gradual decline the last decade. This outcome is hard to detect because the data show considerable fluctuations from one survey wave to the next. Among cold-calling surveys, telephone response rates are typically below 10%, for a range of topics and survey types. Co-operation rates, (the ratio of obtained interviews to refusals) are typically below 0.2 (that is below one interview to five refusals). Telephone interviews with clients have a higher response rate – typically above 20% with co-operation rates above 1.0. It would appear that some topics, such as financial services, may induce a lower level of co-operation. Government sponsored surveys have higher response rates, at times over 50%, but even here a sharp decline in response rates over time for one long running monitor was observed. Co-operation rates were also higher in government sponsored surveys.
One long data series from a telephone omnibus suggested that the “Do Not Call Register” which began in May, 2007 had some positive effects for the industry. Initially there was a spike in both response rates and co-operation. Although this was relatively short-lived, response rates thereafter declined more slowly and co-operation rates were somewhat higher and remained stable. These conclusions should be regarded as tentative as more data series would really be necessary to see if simil
