The major purpose is to understand the actual life of common family. Thus, this survey is an important statistical work of social economic activity. Since this survey has been started, the related research is continued. While the society changes fast, there are many problems in this survey and we must improve it.
This paper is according to the concept of Rolling Samples which is mentioned by Kish. We suggest making the interview-survey monthly. In this way, we can obtain more stable and more reliable information, and we can also obtain seasonal changes. This paper uses the data of the survey on Taipei in 1997 to analyze. We find that making the interview-survey monthly is usable.
