This paper discusses the possibility that an Internet survey using volunteer access panels can measure the transition of public opinion. Any person who is an Internet user and has registered voluntarily can be a member of the volunteer access panels. Thus, a volunteer access panel represents not only a target population but also the Internet users in it. Monthly survey results over a period of eighteen months have been reported in this paper. These Internet surveys were conducted on the members of the volunteer access panel. Further, the survey results were compared with those of the consumer confidence survey that is conducted by the Cabinet Office. Subsequently, deviations as well as some correlations were observed between these two survey results.
