In Korea, over-representation in certain ages, genders and occupational groups has been repeated. In this regard, it is necessary to resolve the deficiencies in political representation, to secure more balanced and stable political representation by representing various political intentions and interests of citizens, and in particular, to secure a balanced representation of descriptive representation. This paper examines the political representation of underrepresented youth. European countries have a relatively high proportion of young councilors, while the number of young councilors in Korea is under 30(0.0%), under 40(2.3%), and under 45(5.6%). Is the lowest level in the country, and is significantly lower than in OECD countries. To solve this problem, discussions about reform of electoral system should be continued. Recently, in Korea, the Parallel proportional representation has been changed from the Semi-linked proportional representation through the fast track election law. In other words, it is more urgent to secure the institutional device for entry into the elected office as well as to discuss the political representation of the youth as a “representative” who can represent the interests of the youth as a direct actor.
