Granting Immigrants the Right to Vote in National Elections : Empirical Evidence from Swedish Administrative Data

Faced with rising levels of cross-border migration, many countries have extended local voting rights to non-citizen residents. However, empirical evidence indicates that voter turnout among non-naturalized immigrants is lower when compared to citizens. This raises the question of how to explain this difference. A common answer is that the low turnout rates of non-citizen residents are primarily due to the socio-economic composition of this group and the challenges involved in adapting to a new political system. An alternative but less discussed possibility is that the low turnout concerns the nature of the elections. Hence, we examine whether the turnout of non-citizens is hampered because they are only allowed to partake in local elections. Based on a regression discontinuity design (RDD) using Swedish administrative data, we find that turnout could increase by 10–20 percentage points if the voting rights of non-citizens were extended to the national level.
