The younger parents are, the more likely they are to speak Mandarin with their children. Among people from 30-39, 71 % speak Mandarin with their children, whereas only 56 % speak Taiwanese. Among people in their 40s, 68 % speak Taiwanese to their children and 80 % speak Mandarin; yet among people in their 50s, 76 % speak Taiwanese and the number who speak Mandarin drops to 65 %.
三十到三十九歲的人有七成跟子女講國語，但相對講閩南語僅五成六；四十到四十九歲講閩南語的有六成八，國語為八成；但五十到五十九歲講台語的有七成六，國語則降為六成五，顯然父母親年紀越輕，越傾向跟孩子講國語。
