Fixing Youth Turnout: Why We Must Focus on the 18-to-19-Year-Old Gap

Here's a contrarian take that will annoy the turnout wonks: the youth vote isn't collapsing, but it is leaking — and the leak is at the bottom of the age range. If you're working to boost youth turnout, stop obsessing over the overall 47% figure and start asking why 18- and 19-year-olds voted at a rate of just 41% in 2024, a 6-point gap from the all-youth rate that has widened from 4 points in 2020 (CIRCLE). That gap is not a mystery; it's a policy failure. And we know the fix. Minnesota proves it.

The Youth Vote Isn't Dying, It's Just Young

Let's set the stage. In 2024, nearly 50 million Americans ages 18-29 were eligible to vote, including more than 8 million who had turned 18 after the 2022 midterm (CIRCLE). Yet only 47% of them cast a ballot, down from 50% in 2020 (CIRCLE). Before you panic, remember that 47% is still well above the 39% in 2016 (CIRCLE). So we're not in freefall. But here's the thing: the drop is concentrated among the youngest voters. While 18- and 19-year-olds voted at 41%, older youth — those in their mid-20s — voted at higher rates. That gap is not inevitable. It's a sign that our registration systems are failing the newest eligible voters.

Think about what happens when you turn 18. You're probably finishing high school, maybe starting college or a job, and you're suddenly eligible to vote. But unless someone puts a registration form in front of you, it's easy to miss the deadline. That's why 18- and 19-year-olds lag. And it's a problem we can fix — if we stop treating youth turnout as a monolith.

Minnesota's Secret: Automatic Registration and Pre-Registration

Now, imagine you're a county elections official in a state that wants to boost youth turnout. You've read the data, and you know the problem. What do you do? The answer is not another celebrity PSA. It's policy. Look at Minnesota. In 2024, Minnesota's 18- and 19-year-olds voted at a 60% rate, the highest of any state (CIRCLE). That's 19 points above the national average for that age group. And what did Minnesota do differently? According to CIRCLE, they implemented automatic voter registration and pre-registration for 16- and 17-year-olds. These policies mean that when a young person gets a driver's license or ID, they are automatically registered to vote — unless they opt out. And they can pre-register before they turn 18, so they're on the rolls on their birthday.

So if you're a practitioner, the message is clear: stop spending your budget on Instagram ads and start lobbying your state legislature for automatic registration and pre-registration. It's not glamorous, but it works. And it's not just Minnesota. The overall youth turnout in the state was 62% — the highest in the nation (CIRCLE).

But What About the Gender Gap? It's Not Just Age

Of course, the 18-19 gap is not the only fracture. There's also a striking gender gap. Among youth, 50% of young women voted in 2024, versus 41% of young men (CIRCLE). That's a 9-point gap, and it's been persistent. And it matters politically: young women supported Harris by 18 points, while young men supported Trump by 14 points (CIRCLE). So the gender gap is also a partisan gap. If you're a Democrat, you want to close the gender gap by turning out young women; if you're a Republican, you want to turn out young men. But neither side should ignore the age gap, because it's the most fixable.

Here's the thing: the gender gap is partly a participation gap in other civic activities too. Young women are more likely to protest (21% vs. 14%) and sign petitions (60% vs. 51%) (CIRCLE). So the voting gap is part of a broader engagement pattern. But we can't just blame the young men for being lazy. We have to make the system work for them. And that means addressing the fact that many young people, especially those of color, said they didn't vote because they lacked enough information about the process or candidates — 17% of youth of color said that, versus 10% of white youth (CIRCLE). Information is not just a nicety; it's a barrier.

What Works: A Comparison of Interventions

So, what should a practitioner actually do? Let's compare the options based on the evidence.

Now, I'm not saying peer-to-peer texting doesn't work — it might. But the fact base doesn't give us any numbers to support it. What we do have is a clear, measurable effect from policy changes. And that's what we should push for.

Here's a concrete scenario: You're a state legislator in a state with low youth turnout. You have a choice between funding a flashy get-out-the-vote campaign and introducing a bill for automatic voter registration. The fact base says the bill is the better bet. Minnesota's 18-19 turnout was 60%, and that state has AVR and pre-registration. Meanwhile, in Arkansas, youth turnout was 33% — the lowest in the nation (CIRCLE). What's the difference? Policy. So if you want to move the needle, move the policy.

And don't forget: the youth vote is not just about the presidency. In 2025, in the New York City mayoral election, 75% of NYC youth voted for Zohran Mamdani, who won with 50% overall (CIRCLE). That's a massive youth surge for a progressive candidate. And in Virginia and New Jersey, youth turnout rose by 7 and 9 points, respectively, in 2025, with 70% of Virginia youth backing Abigail Spanberger and 69% of New Jersey youth backing Mikie Sherrill (CIRCLE). These are not flukes. When youth do vote, they vote in blocs. The problem is getting them to the polls.

Bottom Line

The single best move for anyone serious about increasing youth turnout is to push for automatic voter registration and pre-registration for 16- and 17-year-olds. Minnesota's 60% turnout among 18- and 19-year-olds proves it works. Stop wringing your hands about the overall 47% and start closing the 6-point age gap. That's where the future of the electorate is being decided.
