Abstract

It is often argued that non-citizens are less interested in the political processes of the host country and, therefore, vote less than citizens. We discuss this using Chile's administrative electoral census for the 2012-2023 elections. We choose Chile for three reasons. First, it is one of the few countries worldwide that allows non-citizens to vote in local and national elections. Second, Chile requires only five years of permanent residence for non-citizens to vote. Third, Chile implemented a voluntary voting system between 2012 and 2021 and a compulsory voting system in 2022. This latter particularity means that voting is compulsory for non-citizens registered on the electoral roll. How much and how did the electoral participation of citizens and non-citizens change with the introduction of compulsory voting? Four results stand out. First, citizen turnout averaged 44.7% under voluntary voting, while non-citizen turnout averaged 17.1%. Second, with the introduction of compulsory voting, the figures narrowed. Citizens averaged 86.3% and non-citizens 60.0%, tripling their turnout compared to elections organised under voluntary voting. Third, there is a gender gap in voter turnout in favour of women, both among citizens and non-citizens. Fourth, since 2020-when a constitutional referendum was held during the Covid-19 pandemic-there has been a higher turnout of young people in citizen and non-citizen groups. These results are beneficial for assessing the institutions that regulate the right and exercise of the vote for non-citizens, the impact of compulsory voting on electoral participation, and the re-boosting of youth participation.
