Cognitive Testing Research

The purpose of cognitive testing is to explore, understand and explain the diversity and range of ways in which people go about answering survey questions. This allows the researcher to ascertain whether or not a question is working as intended, and whether the information that respondents need to enable them to answer accurately is available. Cognitive testing can also aid the development of questionnaires by suggesting improved and unambiguous question wording, layout and routing.

Hence, in order to finalise the question set and questionnaire for the 2011 census, we commissioned Ipsos MORI, a leading research company in the UK, to conduct cognitive testing of selected questions and the questionnaire as a whole. This work was conducted throughout 2009 and reports from the testing are available, as follows:
