Response rate (RR) is the most important index for evaluating survey quality. This article analyzes RR trends of different survey methods to figure out their limitations. The RR of face-to-face surveys conducted by Japanese news media continues to decline. However, the RR of the Cabinet Office of the Japanese Government indicates recovery as a V-curved line. The difference between the two is unusual. As the RR of telephone surveys conducted in Japan is not calculates accuturately, it is not possible to evaluate the quality of the survey results. The American Association for Public Opinion Research (AAPOR) provides six definitions of RR. Based on these definitions, the RR in random digit dialing (RDD) surveys in the U.S.A shows a rapid decline. Therefore, new experiments are being conducted in the U.S.A. to replace RDD.
