Using Telephone Survey Sample Data as a Feasible Resolution to the Difficulty of Indigenous Survey
There is a lack of indigenous object research inside the nation, and the research is usually attached to national sample as one of the small sample analysis. The main reason is that with only about 2% of the country's total population, indigenous population is rather few in Taiwan. Besides, uneven geographic distribution and the factor that a considerable number of workplace/residence and domicile difference due to livelihood are other reasons which cause difficulty to traditional method of investigation. Both face-to-face interview or telephone interview have handicap on sampling. However, public opinion polls had become more universal in recent years. Academic and private investigation agency all has accumulated a large number of successful phone survey samples, which contained numerous Han samples and certain proportion of indigenous samples. If there is a possibility to get these samples which were ＂not originally using indigenous population as statistic population, but contain successful indigenous samples,＂ and apply data mining technology to dig the ＂valuable mineral＂ out from a large amount of ＂useless＂ information, then it will be probable to directly filter out the indigenous samples that were needed, and solve the problems mentioned above in the context of saving cost. In this view, the research team and Taiwan Real Survey Co. had cooperated and merged the successful indigenous population phone interview samples, which are from national samplings that were executed by the company since 2007 so far (March 2013), as indigenous telephone database. Preliminary research result shows, by using telephone interview sample database that was consolidated by data mining and double sampling, the characteristics of successful samples which got from the telephone interview are similar to the indigenous statistic population in the official population statistics. Other than that, including multi-year indigenous population phone data could enhance the collection range of the indigenous telephone database, and reduces the cost of sample acquisition.
