Young voters make up the largest portion of the electorate but vote at the lowest rates of any age group. While scholars have studied how culture affects youth political participation, few studies have analyzed how institutional barriers affect youth voting—even though these laws have been found to affect turnout of other disadvantaged groups. Considering younger citizens are more likely to be non-habitual voters with less political knowledge, efficacy, and resources, it is possible that these laws have magnified effects for youths. This could explain why new voters, facing new restrictions to voting, are participating at lower percentages than youths of earlier cohorts. Using the 2004–2016 Current Population Survey ( N = 360,000) and the Cost of Voting Index to test the effects of restrictive electoral environments on youth turnout, we find that restrictive environments disproportionately hurt young voters by decreasing the probability they turn out by 16 percentage points, compared with older voters.
