This study we analyzed the correlation between high school students’ awareness of lowering the age of majority and other survey items. The results revealed a positive correlation between agreement with lowering the age of majority and the rate of communication with family members. Furthermore, there was a significant difference between high school students who think positively about lowering the age of majority and those who think negatively about it. These results suggested that future consumer education requires guidance to broaden awareness and values among high school students.
