The sampling of the ASAHI SHIMBUN telephone survey method was the same as the sampling of the face to face survey method. It was the random selection of samples from the electoral registers. But, as we couldn't know all the telephone numbers of the samples, we couldn't make contact with every sample taken. The respondents to telephone survey were less than those of the face to face survey, especially in young persons and urban dwellers. The representativeness of sample was somewhat inferior to the face to face survey, nevertheless, we think the telephone survey is method effectively measures indicates and the tide of public opinion without delay.
