This thesis aims to describe and analyse how young people reason around voting and voter turnout in two different national contexts - Sweden and the United States - and how the reasoning might differ. The material has been gathered in qualitative interviews with students in both countries and ordered according to a typology of four theories, namely rational choice, new institutionalism, social identity and norm theories. Findings indicate that there is much difference in the reasoning between the countries while similarities may be due to them being students of similar ages. In the US, young people reason more according to rational institutionalism, about the system itself and seem to be rather cynical about it while the Swedish youths reason more in terms of institutional norms and seem to be satisfied with the system of voting at large. This thesis develops previous research by adding qualitative findings to hard facts which can be used to understand voters and national contexts more thoroughly.
