In 2022, 77.9 percent of people aged between 65 and 74 years old were registered to vote in the United States - the highest share of any age group. In comparison, 49.1 percent of 18 to 24 year-olds were registered to vote in that year.

Since 1964, voter turnout rates in U.S. presidential elections have generally fluctuated across all age groups, falling to a national low in 1996, before rising again in the past two decades. Since 1988, there has been a direct correlation with voter participation and age, as people become more likely to vote as they get older. Participation among eligible voters under the age of 25 is the lowest of all age groups, and in the 1996 and 2000 elections, fewer than one third of eligible voters under the age of 25 participated, compared with more than two thirds of voters over 65 years.

During the weeks leading up to the presidential election, early voting began in almost all states, with over 80 million ballots being cast nationally as of Election Day. Although 39 percent of mail-in and early in-person votes were cast by voters aged 65 or older, ten percent of those aged 18 to 29 years old voted early.

In the 1824 U.S presidential election, which was the first where a popular vote was used to determine the overall winner, approximately three percent of the U.S. population voted in the election, while only one percent actually voted for the winner. Over the following decades, restrictions that prevented non-property owning males from voting were gradually repealed, and almost all white men over the age of 21 could vote by the 1856 election. The next major development was the 15th Amendment to the U.S. Constitution following the American Civil War, which granted suffrage to all male citizens of voting age, regardless of race. Turnout then grew to almost twenty percent at the turn of the century, however Jim Crow laws played a large part in keeping these numbers lower than they potentially could have been, by disenfranchising black communities in the south and undoing much of the progress made during the Reconstruction Era. Extension of voting rights Female suffrage, granted to women in 1920, was responsible for the largest participation increase between any two elections in U.S. history. Between the 1916 and 1920 elections, overall turnout increased by almost seven percent, and it continued to grow to 38 percent by the 1940 election; largely due to the growth in female participation over time. Following a slight reduction during the Second World War and 1948 elections, turnout remained at between 36 and forty percent from the 1950s until the 1990s. Between these decades, the Voting Rights Act of 1965 and the Twenty-Sixth Amendment in 1971 respectively re-enfranchised many black voters in the south and reduced the voting age in all states from 21 to 18 years old. Participation among female voters has also exceeded male participation in all elections since 1980. Recent trends The 1992 election was the first where more than forty percent of the total population cast ballots, and turnout has been above forty percent in all presidential elections since 2004. Along with the extension of voting rights, the largest impact on voter turnout has been the increase in life expectancy throughout the centuries, almost doubling in the past 150 years. As the overall average age has risen, so too has the share of the total population who are eligible to vote, and older voters have had the highest turnout rates since the 1980s. Another factor is increased political involvement among ethnic minorities; while white voters have traditionally had the highest turnout rates in presidential elections, black voters turnout has exceeded the national average since 2008. Asian and Hispanic voter turnouts have also increased in the past twenty years, with the growing Hispanic vote in southern and border states expected to cause a major shift in U.S. politics in the coming decades.

In terms of the most popular presidents, in the 1940 election, Franklin D. Roosevelt became the first president to have been elected by more than one fifth of the total population. Three presidents were elected by more than 22 percent of the total population, respectively Lyndon B. Johnson in 1964, Richard Nixon in 1972 and Barack Obama in 2008, while Ronald Reagan's re-election in 1984 saw him become the only president in U.S. history to win with the support of more than 23 percent of the total population. While the vote count for the 2020 election is still to be finalized, President-elect Joe Biden has already received 81.28 million votes as of December 02, which would also translate to over 24.5 percent of the total population, and will likely near 25 percent by the end of the counting process.

According to a 2023 survey of young adults in the United States, just over half of Americans between 18 and 24 years old were planning on voting in the 2024 presidential election. The likelihood among those between the ages of 25 and 34 was only slightly greater.

According to a November 2023 survey, motivation levels among 18 percent of Americans between the ages of 18 and 34 to vote in the 2024 presidential election has lessened compared to past elections, compared to only eight percent of voters between 35 and 49 years old.

In the U.S. midterm elections, there is a large disparity in voting participation among eligible voters under the age of 25, and all other age groups. Since 1986, statistics show that voter participation directly correlates with age, with those in higher age brackets more likely to vote in midterm elections; a similar correlation has appeared in presidential elections since 1988, although turnout in these elections is significantly higher. From 1966 until 2014, voter participation gradually decreased (although sometimes fluctuated) among voters under 65 years of age; while it generally increased (and plateaued around sixty percent) among those older than 65. The 2018 midterms saw large increases in voter participation across all age groups, with the largest increases coming from younger voters; in spite of this, eligible voters over the age of 65 were still more than twice as likely to vote as those under 25.

In 2022, there were 161.42 million people registered to vote in the United States. This is a decrease from the previous election, when 168.31 million people were registered to vote.

Voting requirements

While voting laws differ from state to state, the basic requirements are the same across the entire country. People are allowed to vote in elections in the United States if they are a U.S. citizen, meet their state’s residency requirements, are at least 18 years old before Election Day, and are registered to vote before the registration deadline.

Vote early and often

Generally, younger people are not registered to vote at the same rate as older individuals. Additionally, young people tend not to vote as much as older people, particularly in midterm elections. However, in the 2016 presidential election, a significant number of people across all age groups voted in the election, resulting in a high voter turnout.

In U.S. presidential elections since 1964, voters in the 18 to 24 age bracket have traditionally had the lowest turnout rates among all ethnicities. From 1964 until 1996, white voters in this age bracket had the highest turnout rates of the four major ethnic groups in the U.S., particularly those of non-Hispanic origin. However participation was highest among young Black voters in 2008 and 2012, during the elections where Barack Obama, the U.S.' first African-American major party candidate, was nominated. Young Asian American and Hispanic voters generally have the lowest turnout rates, and were frequently below half of the overall 18 to 24 turnout before the 2000s.

According to exit polling in ten key states of the 2024 presidential election in the United States, Donald Trump received the most support from men between the ages of 45 and 64. In comparison, 61 percent of women between the ages of 18 and 29 reported voting for Kamala Harris.

According to exit polling in the 2020 Presidential Election in the United States, 62 percent of surveyed 18 to 29 year old voters reported voting for former Vice President Joe Biden. In the race to become the next president of the United States, 51 percent of voters aged 65 and older reported voting for incumbent President Donald Trump.

Throughout United States history, voter turnout among the voting eligible population has varied, ranging from below twelve percent in uncontested elections, to 83 percent in the 1876 election. In early years, turnout in presidential elections was relatively low, as the popular vote was not used in every state to decide who electors would vote for. When this was changed in the 1824 election, turnout increased dramatically, and generally fluctuated between seventy and eighty percent during the second half of the nineteenth century. Until the 1840 and 1842 elections, midterm elections also had a higher turnout rate than their corresponding presidential elections, although this trend has been reversed since these years.

Declining turnout in the twentieth century An increase in voting rights, particularly for black males in 1870 and for women in 1920, has meant that the share of the total population who are legally eligible to vote has increased significantly; yet, as the number of people eligible to vote increased, the turnout rate generally decreased. Following enfranchisement, it would take over fifty years before the female voter turnout would reach the same level as males, and over 150 years before black voters would have a similar turnout rate to whites. A large part of this was simply the lack of a voting tradition among these voter bases; however, the Supreme Court and lawmakers across several states (especially in the south) created obstacles for black voters and actively enforced policies and practices that disenfranchised black voter participation. These practices were in place from the end of the Reconstruction era (1876) until the the Voting Rights Act of 1965 legally removed and prohibited many of these obstacles; nonetheless, people of color continue to be disproportionally affected by voting restrictions to this day.

Recent decades In 1971, the Twenty-sixth Amendment lowered the minimum voting age in most states from 21 to 18 years old, which greatly contributed to the six and eight percent reductions in voter turnout in the 1972 and 1974 elections respectively, highlighting a distinct correlation between age and voter participation. Overall turnout remained below sixty percent from the 1970s until the 2004 election, and around forty percent in the corresponding midterms. In recent elections, increased political involvement among younger voters and those from ethnic minority backgrounds has seen these numbers rise, with turnout in the 2018 midterms reaching fifty percent. This was the highest midterm turnout in over one hundred years, leading many at the time to predict that the 2020 election would see one of the largest and most diverse voter turnouts in the past century, although these predictions then reversed with the arival of the coronavirus (COVID-19) pandemic. However, 2020 did prove to have the highest turnout in any presidential election since 1900; largely as a result of mail-in voting, improved access to early voting, and increased activism among grassroots organizations promoting voter registration.

In 2022, about 70 percent of women in the United States were registered to vote. This is higher than the share of men who were registered to vote in that same year.

In the 2016 presidential election, turnout among those aged 45 to 64 years reached its lowest level, at less than 62 percent, but it then rose above 65 percent in 2020. White voters in this age bracket have had the highest turnout rate in all of these elections, especially white voters of non-Hispanic origin; except for the 2012 election where Black voters had the highest turnout rate. As with other age groups, Asian American and Hispanic voters traditionally have much lower turnout rates, often around half of the national average for those in the 45 to 64 age bracket.

According to exit polling in ten key states of the 2024 presidential election in the United States, Donald Trump received the most support from white voters between the ages of 45 and 64. In comparison, 84 percent of Black voters between the ages of 18 and 29 reported voting for Kamala Harris.

In the 2020 presidential election, about 55 percent of voters aged between 18 and 29 participated in the election -- a significant increase from the previous election year, when about 44 percent of youths voted in the election. The highest youth turnout rate was in 1972, when 55.4 percent of voters between the ages of 18 and 29 voted in the election.

In U.S. presidential elections since 1964, voter turnout among male and female voters has changed gradually but significantly, with women consistently voting at a higher rate than men since the 1980 election. 67 percent of eligible female voters took part in the 1964 election, compared to 72 percent of male voters. This difference has been reversed in recent elections, where the share of women who voted has been larger than the share of men by around four percent since 2004.

United States presidential elections are quadrennial elections that decide who will be the President and Vice President of the United States for the next four years. Voter turnout has ranged between 54 and 70 percent since 1964, with white voters having the highest voter turnout rate (particularly when those of Hispanic descent are excluded). In recent decades, turnout among black voters has got much closer to the national average, and in 2008 and 2012, the turnout among black voters was higher than the national average, exceeded only by non-Hispanic white voters; this has been attributed to Barack Obama's nomination as the Democratic nominee in these years, where he was the first African American candidate to run as a major party's nominee. Turnout among Asian and Hispanic voters is much lower than the national average, and turnout has even been below half of the national average in some elections. This has been attributed to a variety of factors, such as the absence of voting tradition in some communities or families, the concentration of Asian and Hispanic communities in urban (non-swing) areas, and a disproportionate number of young people (who are less likely to vote).

As of March 2022, a survey conducted among registered voters in the United States found that 12 percent of respondents aged between 35 and 44 years old expect to use Donald Trump's new social platform, Truth Social, a lot. Overall, 28 percent of 18 to 34 year olds reported they would use the former Presidents social media network sometimes. The majority of respondents stated that they did not expect to use Truth Social, owned by Trump Media and Technology, at all.

This statistic shows the share of voters in Pennsylvania in the 2016 presidential election, by age and voter registration status. In that year, 61 percent of voters ages 30 to 39 voted in the election.
