Ever get that feeling that everyone is shouting about politics, but nobody is actually looking at the guest list? We talk about "the American people" like it’s one big, unified group waiting to pull a lever. But the reality of the number of eligible voters in america is way messier—and frankly, more interesting—than just a single giant number on a spreadsheet.
Honestly, if you ask the average person on the street how many people can actually vote, they’ll probably give you a blank stare or guess the entire population of the country. But there is a massive gap between "people living here" and "people who can legally cast a ballot."
The "Big Three" Numbers You Need to Know
When we talk about the electorate, experts like Dr. Michael McDonald at the University of Florida (the guy behind the Election Lab) usually break it down into three distinct buckets. If you mix these up, your stats are basically junk.
- VAP (Voting-Age Population): This is every single human being living in the U.S. who is 18 or older. It doesn’t matter if they are a citizen, a green card holder, or just here on a work visa. In 2024, the Census Bureau pegged this around 260 to 265 million people.
- CVAP (Citizen Voting-Age Population): This is the filter. It’s the VAP minus non-citizens. This is where the number of eligible voters in america starts to take shape. According to recent Census data released in early 2025, there were about 243 million citizens of voting age during the 2024 cycle.
- VEP (Voting-Eligible Population): This is the "real" number. It takes the CVAP and subtracts people who are disqualified—mostly due to felony convictions (depending on the state) or being declared mentally incompetent by a court. It also adds overseas citizens who can still vote.
Basically, the VEP is the actual pool of people who could show up if they wanted to. For the 2024 election, the VEP was estimated to be roughly 236 million people.
Why 89 Million People Just... Didn't
Here is the kicker. In the 2024 presidential election, roughly 154 to 155 million people actually cast a ballot. That sounds like a lot, right? It’s one of the highest turnouts we’ve seen in a century, nearly matching the 2020 record.
But do the math.
If there are 243 million voting-age citizens and only 154 million voted, that means about 89 million eligible voters stayed home. That’s enough people to fill about 1,000 professional football stadiums. It's a staggering number.
Why didn't they show up? Pew Research Center did a deep dive into this, and it’s not just "laziness." In 2024, the "nonvoter" profile looked a lot different than in previous years.
- Education was the biggest predictor. Almost half of the people who didn't vote had a high school education or less.
- Age matters. Only about 15% of voters were under 30, even though they make up about 20% of the eligible population.
- The "Busy" Factor. In the 2022 midterms, nearly 10 million registered people who skipped out said they were just too busy or had a schedule conflict.
The Registration Gap
You’ve probably heard people say that registering to vote is the hardest part. They aren't totally wrong.
In 2024, about 73.6% of the citizen voting-age population was registered. That's roughly 174 million people. If you’re keeping track, that means about 20 million people were "on the books" but decided to sit the 2024 election out anyway.
It’s also worth noting that registration isn't permanent in most places. If you move, you might fall off the rolls. Some states, like North Dakota, don’t require registration at all (must be nice!), while others have "Same Day Registration" (SDR).
What Most People Get Wrong About the "Missing" Voters
There’s a common myth that if all those 89 million people showed up, one party would win in a permanent landslide. Kinda makes sense on paper, but the 2024 data actually broke that theory.
In the past, nonvoters leaned heavily Democratic. But in 2024, the "infrequent" or "new" voters who actually showed up favored Donald Trump by a margin of about 54% to 42%. The people who didn't show up were almost perfectly split. About 44% said they preferred Trump, and 40% preferred Harris.
Basically, the "silent majority" isn't a monolith. It’s just as divided as the rest of us.
The Demographics of the Current Electorate
The number of eligible voters in america is shifting because the country is shifting. It’s not a secret.
- The Silver Tsunami: Voters 65 and older had the highest turnout in 2024 (nearly 75%). They are the only group that actually voted more than they did in 2020.
- The Education Divide: 82.5% of people with advanced degrees voted. Compare that to just 52.5% of high school grads. That is a massive 30-point gap.
- The Gender Gap: Women continue to out-vote men, a trend that hasn't changed since 1980. In 2024, 66.9% of women voted compared to 63.7% of men.
State-Level Nuance: Where It Actually Happens
You can't just look at the national number of eligible voters in america because the "Electoral College" makes the state numbers the only ones that decide the presidency.
Take California vs. Wyoming. California had over 16 million votes cast. Wyoming had about 271,000. In a place like Wisconsin, young voters (18-29) actually show up at pretty high rates. But in Texas? That same age group is "underrepresented" by double digits.
This happens because of state laws. Some states make it incredibly easy to vote by mail—nearly 30% of Americans voted by mail in 2024—while others have tightened the rules.
How to Check Your Own Status
If you’re reading this and wondering if you’re part of that 243 million (and if you’re actually registered), here’s what you should do:

Verify Your Registration Today
Don't wait for an election year. States purge their rolls for "inactivity" all the time. Use a site like Vote.org or your Secretary of State’s website to confirm you are active.
Understand Your State's Disenfranchisement Laws
If you or someone you know has a past conviction, check the laws in your specific state. Many states have recently restored voting rights for formerly incarcerated individuals, but the rules are a patchwork quilt across the US.
Look Up Your Local Deadlines
Registration isn't just a "yes/no" thing. Many states require you to be registered 30 days before an election. If you’re moving, you basically need to re-register immediately to ensure your voice counts in your new district.
The number of eligible voters in america is a living, breathing stat. It changes every day as people turn 18, naturalize as citizens, or move across state lines. Staying informed about these numbers isn't just for political junkies; it's about understanding who actually holds the power in a democracy.
The most important takeaway? Having the right to vote and being "eligible" is just the baseline. The real power only shows up in the "ballots cast" column.
