Longer‐Term Effects of Voting at Age 16: Higher Turnout Among Young People in Scotland

Debates about the lowering of the voting age to 16 often include claims about the possible longer-term outcomes of earlier enfranchisement for the electorate. It has been shown that, when eligible to vote, 16-and 17-year-olds turn out to vote in higher proportions than slightly older peers (Zeglovits & Aichholzer, 2014). However, questions remain regarding the longevity of this early voter boost and whether it carries on as young people grow older (Franklin, 2004, 2020). Using original survey data collected from 863 young people in Scotland, we investigate the outcomes of being eligible to vote in elections from age 16/17 and its effects on political behaviour for young people aged up to 24. We compare levels of political engagement, including voting in the 2021 Scottish parliament elections, among cohorts of young people who were enfranchised at age 16/17 to cohorts who experienced their first election aged 18 or older. We show that young people who were eligible to vote at 16/17 exhibited greater levels of turnout in the 2021 Scottish parliament elections, up to seven years after the initial lowering of the voting age than those who got to vote for the first time at 18 or older. This finding provides new evidence in support of theories on the longer-term effects of voting at age 16/17 on electoral political engagement. However, we find no similar pattern for non-electoral political engagement, showing that the outcomes of the lowering of the voting age may be limited to turnout.
