現今住宅電話調查中年輕樣本不足的情形一般皆歸因於唯手機族的日漸增多。但事實上，在年輕人多半住在多人戶的臺灣家戶結構限制下，現行住宅電話調查先等機率抽戶，再等機率抽人的抽樣設計，本來就不容易接觸到年輕樣本。準此，本研究以2010普查資料為依據調整戶中選樣表，試圖改善年輕樣本不足的情況。結果顯示，抽樣模擬與實際撥打的成效皆不錯。因此，本研究建議每年根據戶籍或普查資料調整戶中選樣表。

The most important reason for the lack of young respondents in telephone surveys may not be the growth of cell-phone-only users among the young generation. Two-stage sampling and household structures are the major factors. Therefore, this study adjusts the method of random sampling within household based on the 2010 census. The results indicate that the adjustment improved participation among young people significantly. Thus, the current research suggests that it is necessary to adjust random selection within household on the basis of census or household registration data annually.
