Voting Age by Country – Where 16 Year Olds Can Vote

Most countries set the voting age (the minimum legal age required to cast a ballot in elections) at 18 years old. However, at least 22 countries allow citizens as young as 16 to vote in some or all elections, including Austria, Scotland, Argentina, and Brazil. The United States maintains a federal voting age of 18, established by the 26th Amendment in 1971.

Which Countries Let 16-Year-Olds Vote?

22 or more nations grant full or partial voting rights at age 16, making this a widespread practice across multiple continents. These countries range from long-established democracies in Europe to nations across Latin America and the Pacific.

Key Finding: Voting at 16 is not a fringe policy. It operates in national elections across Austria, Argentina, Brazil, Cuba, Ecuador, Nicaragua, Scotland (devolved elections), Wales, Isle of Man, Jersey, Guernsey, Malta, Estonia (local elections), Greece (local elections), Norway (pilot programs), Sudan, Timor-Leste, Indonesia (married citizens), and North Korea, among others. Each country defines the scope differently, ranging from all elections to municipal-only participation.

The table below maps the most widely recognized nations granting voting rights at 16, along with the election scope and the year the policy was adopted.

The Full Global Voting Age Map, Region by Region

Understanding voting age requires looking at every inhabited region of the world, not just the countries that make headlines. The picture that emerges is one of genuine diversity, where geography, political tradition, and constitutional history each play a distinct role.

The Americas: A Region Split Between 16 and 18

Latin America has produced the densest concentration of 16-year-old voting rights anywhere in the world. Brazil embedded optional youth suffrage in its 1988 constitution following the end of military dictatorship, making it one of the earliest countries to formalize this right at the constitutional level. Nicaragua lowered its voting age to 16 in 1984 during the Sandinista government, making it one of the earliest adopters globally.

Bolivia lowered its voting age to 18 in its 2009 constitution but has periodic debates about extending rights to 16-year-olds, given that Bolivian law allows young people to work legally from age 14. Venezuela maintains a voting age of 18 despite some early-2000s debates during the Hugo Chavez era about lowering it. Colombia, Chile, Peru, Uruguay, and Paraguay all hold at 18.

Chile conducted a notable policy experiment. In 2021, Chile lowered its voter registration threshold and made voting voluntary for all ages, but kept the minimum at 18. The 2022 Chilean constitutional referendum drew significant youth participation at 18 and above but did not extend rights lower. Cuba has maintained 16 as its voting age since its 1976 constitution.

In North America, both the United States and Canada hold at 18 for all federal elections. Mexico has consistently maintained 18 and is not actively debating a change. Puerto Rico, a U.S. territory, follows the 26th Amendment threshold of 18.

Europe: The Most Active Continent for Voting Age Reform

Europe shows the widest internal variation of any region. The continent contains countries at 16, 17, 18, and historically 21, with active reform movements in multiple nations simultaneously.

Estonia allows 16-year-olds to vote in local elections as of 2017, making it one of the few EU member states beyond Austria and Malta to formally extend youth voting rights. Germany permits 16-year-old voting in state parliament elections in Brandenburg, Bremen, Hamburg, Mecklenburg-Vorpommern, Saxony-Anhalt, Schleswig-Holstein, and Thuringia, and extended 16-year-old voting to European Parliament elections starting in 2024.

Switzerland presents a fascinating case. Switzerland’s federal voting age is 18, but the canton of Glarus lowered its cantonal voting age to 16 in 2007, making it the only Swiss canton where teenagers can participate in direct democratic votes, including the cantonal Landsgemeinde (an open-air assembly where citizens vote by show of hands). Proposals to extend 16-year-old voting to other Swiss cantons have been voted down in referenda in cantons including Zurich, Basel, and Geneva.

Norway conducted a pilot program between 2011 and 2015 in which 16-year-olds in selected municipalities were allowed to vote in local elections. The pilot was evaluated positively in terms of turnout and political knowledge among young voters, but Norway’s national parliament, the Storting, voted against a permanent national extension, with the proposal failing by a narrow margin.

Denmark holds its voting age at 18 but has seen repeated parliamentary proposals to lower it to 16, none of which have passed as of writing. Finland, Sweden, and the Netherlands each maintain 18 and have active but so far unsuccessful youth suffrage movements.

Ireland is worth watching closely. The Citizens’ Assembly on Electoral Reform, a body of randomly selected Irish citizens convened in 2022, recommended lowering the Irish voting age to 16 for all elections. The Irish government has not yet acted on this recommendation, but the process demonstrated how deliberative democracy mechanisms, meaning structured processes where ordinary citizens deliberate on policy questions, can move the voting age debate forward outside of traditional party politics.

Belgium extended 16-year-old voting to European Parliament elections starting in 2024, joining Germany in this specific expansion without changing the domestic national threshold of 18.

Liechtenstein, the tiny principality between Switzerland and Austria, uses a voting age of 18 despite being surrounded by countries with lower thresholds. Luxembourg maintains 18 and uniquely combines this with compulsory voting.

Africa: Patchwork Policies Across a Diverse Continent

Africa’s voting age landscape is among the least discussed globally but contains meaningful variation. The vast majority of African nations set their voting age at 18, including the continent’s two most populous nations, Nigeria and Ethiopia.

Sudan has been cited by some international sources as allowing 17-year-old voting, though Sudan’s electoral environment has been severely disrupted by political instability, the 2019 removal of long-time President Omar al-Bashir, and subsequent military coups in 2021 and 2023. Reliable contemporary electoral data from Sudan is difficult to verify independently.

Morocco lowered its voting age from 20 to 18 in 2002, and its 2011 constitutional reforms following the Arab Spring protests maintained that threshold while expanding political rights in other areas. Tunisia, which also underwent significant democratic transitions during the Arab Spring period, maintained 18 as its voting age.

South Africa holds at 18, as do Kenya, Ghana, Tanzania, Uganda, Rwanda, Senegal, Ivory Coast, and most other sub-Saharan nations. Zimbabwe uses 18. Egypt uses 18. Cameroon and Gabon both use 20 as their minimum voting age, making them outliers in a continent where 18 is the near-universal norm. Cameroon’s elevated threshold has been criticized by electoral reform advocates as an unnecessary restriction on youth political participation.

Asia and the Pacific: Major Shifts in the 2010s

The Asia-Pacific region saw dramatic action in the 2010s decade, with multiple major democracies lowering their voting ages. Japan’s reduction from 20 to 18 in 2016 was the most consequential numerically, adding approximately 2.4 million new young voters. The reform passed through Japan’s National Diet (the bicameral national legislature) with broad cross-party support and was driven in part by concerns about demographic aging and the desire to give younger citizens a voice before they were outnumbered even more sharply by older voters in electoral contests.

South Korea’s reduction from 19 to 18, effective for the April 2020 legislative elections, added roughly 500,000 new voters. The change was passed by South Korea’s National Assembly in December 2019 after years of failed attempts by progressive parties. Thailand maintains 18 but considered lowering the age to 17 in reform discussions following the 2020 youth-led protest movement. No formal change has been enacted.

Myanmar, Vietnam, Cambodia, Laos, and the Philippines all use 18. India lowered its voting age from 21 to 18 via the 61st Constitutional Amendment Act of 1988, which took effect before the 1989 general elections, adding tens of millions of voters in a single policy action. Australia and New Zealand both use 18, with compulsory voting in Australia and voluntary voting in New Zealand.

New Zealand lowered its voting age from 21 to 20 in 1969 and then to 18 in 1974. A legal challenge reached New Zealand’s Supreme Court in 2022, where a youth-led group argued that excluding 16 and 17-year-olds from voting violated the New Zealand Bill of Rights Act 1990. The Supreme Court found in 2022 that the current age limit was inconsistent with the right to be free from age discrimination, a ruling that put significant political pressure on the New Zealand Parliament to act, though as of writing no legislative change has been completed.

Pakistan uses 18, as do Bangladesh, Sri Lanka, and Nepal. China uses 18 for elections to local People’s Congresses, the lowest tier in its electoral system, though meaningful competitive elections do not exist at higher levels. Taiwan maintains 20 as its voting age, one of the higher thresholds among functioning East Asian democracies, though reform proposals to lower it to 18 have been introduced in the Legislative Yuan, Taiwan’s parliament.

The Middle East: Elevated Thresholds and Restricted Franchises

The Middle East contains some of the world’s most restrictive voting environments, where age thresholds intersect with gender restrictions, citizenship rules, and in several cases the absence of meaningful competitive elections. Kuwait sets its voting age at 21, one of the highest in the world among functioning electoral systems. Bahrain uses 18 but has faced significant criticism over the fairness and inclusiveness of its electoral process. Oman also uses 21 for its limited consultative elections. Qatar has held limited municipal elections with a threshold of 18 but does not hold national legislative elections.

Saudi Arabia introduced a voting age of 18 when it first allowed women to vote in 2015 municipal elections, a landmark moment in Saudi political history. Men had previously been allowed to vote in municipal elections since 2005, also at 18.

Iran has had one of the most volatile voting age histories of any country. Iran lowered its voting age to 15 in 1980 following the Islamic Revolution, making it the lowest formal voting age of any country in recent history. The threshold was raised to 16 in 2007 and then to 18 via a parliamentary vote that same year. The back-and-forth reflected internal Iranian political debates about the role of youth in revolutionary politics.

Israel maintains a voting age of 18 for Knesset (parliament) elections, with a robust electoral system that features proportional representation and historically high turnout across most demographic groups.

Turkey lowered its voting age from 21 to 18 in 1995 and has maintained 18 as the operative threshold in recent elections, including the highly contested 2023 presidential and parliamentary elections.

The United States Position in Global Context

The United States set its federal voting age at 18 through the 26th Amendment, ratified on July 1, 1971, making it one of the most consequential constitutional changes of the 20th century. Before this amendment, the federal voting age was 21, and the change was driven significantly by arguments that soldiers who could be drafted and die for their country at 18 deserved the right to vote.

The Oregon v. Mitchell Supreme Court decision of 1970 played a critical role, holding that Congress could lower the voting age to 18 for federal elections but not for state elections, which created administrative chaos and accelerated the push for a constitutional amendment.

Today, no U.S. state permits voting in federal elections below 18, though a small number of cities and municipalities have adopted 16 as the minimum for local elections.

U.S. Cities Where 16-Year-Olds Can Vote Locally

Several American cities allow 16-year-olds to vote in municipal, meaning city-level, elections:

1. Takoma Park, Maryland became the first U.S. city to allow 16-year-old voting in 2013.
2. Hyattsville, Maryland extended local voting rights to 16-year-olds in 2015.
3. Greenbelt, Maryland followed in 2016.
4. Riverdale Park, Maryland adopted the measure in 2016.
5. Berwyn Heights, Maryland joined in 2018.
6. San Francisco, California voters approved 16-year-old voting for local school board elections in 2016.
7. Brattleboro, Vermont and Montpelier, Vermont have pursued or approved similar local measures.

Maryland has emerged as the most active state for sub-federal expansion of teen voting rights, with multiple municipalities independently choosing to lower the local threshold to 16.

State-Level Debates Inside the United States

Beyond cities, several U.S. states have formally debated lowering the voting age at the state level, with none succeeding at statewide application as of writing.

California has seen repeated legislative attempts. A constitutional amendment proposal to allow 17-year-olds to vote in primary elections if they will turn 18 by the general election passed the California legislature but failed to reach voters. A more ambitious proposal to lower the voting age to 16 in all California elections has been introduced multiple times in the California State Assembly without advancing to a floor vote.

Hawaii passed a law allowing 17-year-olds who will be 18 by the general election to vote in primary elections, a narrow extension that mirrors policies in 27 other U.S. states and the District of Columbia. This primary-voting provision for near-eligible 17-year-olds is distinct from a true lowering of the voting age but represents the most common incremental step taken by U.S. states.

Oregon, historically a leader in voting access reforms including vote-by-mail, passed the Motor Voter Act in 2015 creating automatic voter registration but did not lower the minimum age below 18. Oregon activists have proposed a 16-year-old voting measure that has not yet reached the ballot.

Washington, D.C. passed a bill in 2023 lowering the voting age to 16 for all local elections, including mayoral and DC Council races, making it the largest American jurisdiction by population to adopt this policy. The DC Home Rule Charter governs this decision independently, though Congress retains the authority to override DC legislation.

How Europe Compares to the Americas

Europe and Latin America have led the global push to lower voting ages, but through very different political traditions. Austria stands out as the first and so far only European Union member state to grant 16-year-olds full national voting rights in all elections, a right it extended nationwide in 2007.

Latin America presents a remarkable cluster of youth enfranchisement. Argentina, Brazil, Ecuador, and Nicaragua all allow citizens at 16 to vote, though Argentina and Brazil classify this participation as optional for those aged 16 to 17, meaning younger voters can choose to participate but are not legally required to do so. At age 18, voting becomes mandatory in both countries.

The contrast with the United States is notable. While the U.S. debate over lowering the voting age remains largely confined to local and academic circles, countries like Austria and Scotland have produced measurable data showing that 16-year-old voters turn out at rates comparable to or even higher than voters in their early 20s, a fact that political scientists have used to challenge the assumption that younger voters are inherently less engaged.

Why Voting Age Varies So Widely

The voting age in any given country reflects a combination of constitutional tradition, political movement pressure, and evolving legal definitions of civic maturity. There is no universal international standard set by bodies such as the United Nations or the Inter-Parliamentary Union (the oldest international parliamentary organization in the world, founded in 1889), though the UN Convention on the Rights of the Child implicitly shaped discussions about youth political participation in many signatory nations.

Key factors that drive voting age decisions include:

• Military conscription age: Nations that draft soldiers at 18 often face pressure to grant political voice at the same age.
• Age of criminal responsibility: Countries where young people can be tried as adults at 16 sometimes face logical pressure to extend civic rights at the same age.
• Driving and working rights: In many countries, 16-year-olds can drive, work, and pay taxes, creating arguments for political representation.
• Youth activism movements: Organized youth advocacy campaigns have demonstrably shifted policy in Scotland, Wales, Austria, and several Latin American countries.
• Constitutional amendment difficulty: In countries like the United States where constitutional change requires supermajority approval, voting age reform faces structural barriers that do not exist in parliamentary systems.
• Electoral system type: Countries using proportional representation, meaning a system where seats are allocated based on each party’s share of the total vote, tend to be more receptive to expanding the electorate than countries using winner-take-all systems.
• Demographic pressures: Aging populations in Japan, South Korea, and much of Europe have motivated governments to enfranchise younger voters to counterbalance the growing electoral weight of older citizens.

The Role of Referenda and Citizens’ Assemblies

An underappreciated driver of voting age change is the mechanism of direct democracy itself. Switzerland’s Glarus canton lowered its voting age to 16 through a direct democratic vote at its annual Landsgemeinde in 2007. Scotland’s decision to use 16 as the voting age for its independence referendum was formally recommended by a committee of the Scottish Parliament and approved by a vote of the full parliament.

Ireland’s Citizens’ Assembly on Electoral Reform in 2022 recommended lowering the Irish voting age to 16 through a deliberative process rather than a party political one, suggesting that when ordinary citizens rather than politicians make the decision, they often favor expansion of youth rights. This pattern of citizens’ assemblies recommending lower voting ages has emerged in multiple countries including Canada at the provincial level and in academic reform proposals in the United States.

Scotland and Wales as Case Studies

Scotland impressively represents one of the most closely watched experiments in lowering the voting age, as it granted 16-year-olds the right to vote in the 2014 Scottish Independence Referendum, a historic vote on whether Scotland should leave the United Kingdom. Turnout among 16 and 17-year-old Scottish voters in that referendum reached approximately 75%, a figure that challenged assumptions about youth political disengagement.

Wales followed a similar path, extending voting rights to 16-year-olds for elections to the Senedd Cymru, the Welsh Parliament, beginning in 2021. Both Scotland and Wales exercise devolved authority, meaning they govern themselves in many domestic areas independently of the UK Parliament in Westminster, which still maintains the voting age of 18 for UK-wide general elections.

This creates a split system within the United Kingdom itself: a 16-year-old in Edinburgh, Scotland, can vote for their Scottish Parliament representative but cannot vote in a UK general election until they turn 18. Supporters argue this inconsistency points toward an inevitable national lowering of the age, while opponents argue the two election types carry different weight.

What the Scottish and Welsh Data Actually Shows

Post-referendum research conducted by teams at the University of Edinburgh and the Electoral Reform Society produced findings that were widely cited in subsequent international debates. Among the key data points:

• 16 and 17-year-old Scottish voters in 2014 were more likely to discuss politics with family and peers than first-time voters aged 18 to 24.
• First-time young voters who vote at 16 are statistically more likely to become habitual voters, meaning they develop a voting habit that persists across subsequent elections.
• Political knowledge scores among 16 and 17-year-olds surveyed before the referendum were comparable to those of 18 to 24-year-olds on most tested topics.
• School-based civic education programs, amplified by the referendum campaign, produced measurable increases in political awareness among those just below voting age as well.

Wales collected its own post-election data after the 2021 Senedd election. The Electoral Commission Wales reported that 16 and 17-year-old turnout was lower than the overall national turnout but meaningfully higher than turnout among 18 to 24-year-olds in previous comparable elections, suggesting that voting at 16 captures young people before civic disengagement patterns set in.

The Global Outliers: Voting Ages Above and Below 18

While 18 is the global norm and 16 is the second most common threshold, a small number of countries set their voting age at different points entirely.

The Maldives set its voting age at 18 in a landmark 2008 constitutional reform that replaced a 21-year threshold. South Korea lowered its voting age from 19 to 18 in 2019, effective for the 2020 legislative elections, adding roughly 500,000 new eligible voters in a single policy change. Japan lowered its voting age from 20 to 18 in 2016, adding approximately 2.4 million young voters to its electorate.

Arguments For and Against Lowering the U.S. Voting Age

The debate over whether the United States should lower its national voting age to 16 spans constitutional, developmental, and civic dimensions. Those supporting a lower threshold point to evidence from Austria and Scotland showing that 16-year-olds who are allowed to vote participate at meaningful rates and demonstrate knowledge of civic issues comparable to older first-time voters.

Those opposed often cite neuroscience research suggesting that the prefrontal cortex, the brain region most associated with long-term decision-making and impulse control, is not fully developed until the mid-20s. Critics argue that setting voting age policy based on civic engagement metrics alone ignores developmental science.

The National Youth Rights Association, a U.S. advocacy group, has actively campaigned for lowering the federal voting age to 16 since its founding. Legislative proposals have been introduced in Congress but have not advanced to a floor vote as of the time of this writing.

Key Finding: Representative Grace Meng of New York introduced a constitutional amendment proposal in the U.S. House of Representatives to lower the federal voting age to 16. The proposal did not receive a committee vote, reflecting the significant political barriers to amending the 26th Amendment.

The Neuroscience Debate in Detail

The neuroscientific argument against lowering the voting age is frequently cited but often oversimplified. The research on adolescent brain development, much of it associated with scientists including Laurence Steinberg of Temple University, does show that the prefrontal cortex continues developing into the mid-20s. However, this research distinguishes between two types of decision-making: hot cognition, meaning impulsive decisions made under emotional pressure or peer influence, and cold cognition, meaning deliberative decisions made calmly with time to reflect.

Voting is widely considered a cold cognition activity. A voter choosing between candidates or ballot measures is not making a split-second decision under social pressure in the way that a teenager might make an impulsive choice in a peer group. Researchers including Jan Eichhorn of the University of Edinburgh have argued that this distinction undermines the application of hot cognition neuroscience to the voting age debate.

Opponents of this reframing note that the electoral environment itself can be emotionally charged, particularly during highly contested elections where social media, family pressure, and community identity strongly influence voting decisions. The empirical question of whether 16-year-olds make voting decisions through deliberative or reactive processes remains genuinely contested in the academic literature.

Civic Education as a Linked Variable

One consistent finding across countries that have lowered the voting age is that the quality of civic education in schools significantly mediates the outcomes. In Scotland, the Curriculum for Excellence, Scotland’s national curriculum framework, includes substantial political literacy components that were actively reinforced during the 2014 referendum campaign. In Austria, civic education is a required subject and the proximity of school-based civic learning to the newly lowered voting age was seen as a deliberate policy pairing.

In the United States, the quality of civic education varies enormously by state and school district. The National Assessment of Educational Progress (NAEP) civics assessment, sometimes called the Nation’s Report Card, consistently shows that fewer than 25% of American eighth-graders score at or above the proficient level in civics. Advocates for lowering the U.S. voting age argue that this fact strengthens rather than weakens the case for doing so at 16, when students are still embedded in the school system and can receive targeted civic preparation. Critics argue the low civics scores are a reason to maintain rather than lower the voting threshold.

Mandatory vs. Optional Voting and Its Interaction With Age

An important distinction exists between countries that treat voting as a civic right and those that treat it as a civic obligation. Compulsory voting, meaning a legal requirement to cast a ballot or face a fine, exists in 27 countries worldwide according to the International Institute for Democracy and Electoral Assistance (known as International IDEA, founded in 1995 in Stockholm, Sweden).

In Brazil and Argentina, voting becomes mandatory at 18 but remains optional between 16 and 17. This creates a unique policy design where young voters receive an invitation rather than a legal summons, which some researchers argue produces more intrinsically motivated early civic participation.

Australia maintains compulsory voting for all eligible citizens starting at 18, with fines for non-compliance ranging from $20 AUD for a first offense to higher amounts for repeat non-voters. The Australian Electoral Commission administers this system, which has produced consistently high national turnout rates of over 90% in federal elections.

The United States practices entirely voluntary voting at all levels. No state requires citizens to cast a ballot, and national turnout in presidential elections has typically ranged between 50% and 65% of eligible voters in recent decades.

Countries With Compulsory Voting and Their Age Thresholds

The interaction between compulsory voting and age thresholds creates interesting policy combinations. In Ecuador, a 16-year-old who chooses to participate does so voluntarily, but once they cross into compulsory territory at 18, non-participation carries legal consequences. This two-stage structure is one of the more thoughtfully designed approaches to youth suffrage anywhere in the world.

What the Data Tells Us About Youth Voter Turnout

Turnout data from countries that have lowered the voting age provides some of the clearest evidence in this policy debate. In Austria, studies conducted after the 2007 reform found that 16 and 17-year-old voters turned out at rates roughly equal to or above those of voters aged 18 to 25. This pattern challenges the assumption that younger voters are less likely to participate once given the opportunity.

Scotland’s 2014 independence referendum produced a 75% turnout rate among newly enfranchised 16 and 17-year-olds, which was higher than the national average for voters aged 18 to 24. Wales has collected turnout data since 2021 and early findings suggest similar patterns of engaged participation among the youngest eligible voters.

These findings have been cited by researchers at institutions including the University of Edinburgh, the London School of Economics, and the Center for Information and Research on Civic Learning and Engagement (CIRCLE), a U.S.-based youth civic engagement research organization based at Tufts University, as evidence that 16 is a defensible and potentially effective minimum voting age from a participation standpoint.

Comparing Youth Turnout Across Key Elections

The Takoma Park data is instructive for an American audience. While the raw turnout number of approximately 17% looks low compared to Scotland’s 75%, it occurred in an off-cycle municipal election where overall turnout was also very low. The fact that young voters showed up at all in a low-salience local race was considered meaningful by researchers studying the program.

How Supranational Bodies Treat Voting Age Questions

The European Parliament, the directly elected legislative body of the European Union, passed a resolution in 2022 calling on all EU member states to lower their national voting ages to 16 for European Parliament elections. As of writing, Austria and Malta are the only EU members that allow 16-year-olds to vote in EU Parliament elections nationally. Germany extended 16-year-old voting rights to EU Parliament elections starting with the 2024 elections, a significant expansion affecting millions of young German citizens.

The Council of Europe, a separate human rights organization distinct from the EU that includes 46 member states, has also issued recommendations encouraging member governments to consider lowering voting ages, though these carry no binding legal force.

The United Nations has not set a specific recommended voting age, instead deferring to the principle of national self-determination in electoral matters. However, the UN Human Rights Committee has noted that states should ensure their electoral laws do not arbitrarily restrict political participation.

International IDEA and Global Tracking

International IDEA, the International Institute for Democracy and Electoral Assistance, maintains one of the most comprehensive databases of electoral law worldwide, tracking voting age, registration requirements, compulsory voting status, and related variables for nearly every country. Their data shows a clear directional trend: no country has raised its voting age since the 1970s, while numerous countries have lowered theirs. This one-directional movement across more than 50 years of electoral history is one of the strongest arguments that the global trend toward lower voting ages reflects a durable shift in political philosophy rather than a temporary experiment.

The Inter-Parliamentary Union (IPU), founded in 1889 and based in Geneva, Switzerland, similarly tracks voting age data and has observed that the average voting age globally has fallen from approximately 21 in the mid-20th century to 18 today, with active movement toward 16 in multiple regions.

Connecting Voting Age to Broader Civic Rights

Voting age decisions rarely exist in isolation. They interact with a country’s other legal age thresholds in ways that either create consistency or striking contradictions. In the United States, the age landscape looks like this:

This table reveals a notable asymmetry: Americans can pay taxes starting in their early teenage years, can join the armed forces and potentially die in combat at 18, but cannot purchase alcohol until 21 or run for president until 35. Youth voting advocates frequently point to this inconsistency as a reason to extend voting rights to 16-year-olds, who already bear civic responsibilities in the form of tax withholding from part-time employment.

The Taxation Without Representation Argument

The phrase “no taxation without representation” holds particular resonance in American political culture given its role in the rhetoric of the American Revolution. Youth voting advocates in the United States have revived this framing specifically in the context of 16-year-olds who work part-time jobs and have federal income tax, Social Security tax, and Medicare tax withheld from their paychecks.

The Internal Revenue Service (IRS) requires tax withholding from earned income regardless of the earner’s age. A 16-year-old working after school at minimum wage in most states will have taxes withheld from every paycheck and must file a federal return if their income exceeds the filing threshold. This legal reality, that 16-year-olds fund federal programs through taxation without having any electoral mechanism to influence how those funds are spent, is central to the moral argument advanced by organizations like the National Youth Rights Association and academic advocates like Joshua Douglas of the University of Kentucky College of Law, who has written extensively on youth voting rights.

Opponents of this argument note that many non-voters, including non-citizen permanent residents, also pay taxes without voting rights, and that taxation and voting have not historically been treated as legally linked rights in U.S. constitutional jurisprudence since the elimination of poll taxes by the 24th Amendment in 1964.

The Gender and Disenfranchisement History That Shaped Modern Age Debates

The current global voting age landscape cannot be fully understood without recognizing that voting age debates have always existed alongside debates about who else is excluded from the franchise. Women were denied the vote in most democracies until the 20th century. The United States granted women the right to vote through the 19th Amendment in 1920. Switzerland, which lowered its federal voting age from 20 to 18 in 1991, did not grant women the right to vote in federal elections until 1971 and did not complete women’s suffrage at the cantonal level until 1990, when the canton of Appenzell Innerrhoden was ordered to allow women’s voting by the Swiss Federal Supreme Court.

This context matters because it demonstrates that electoral age thresholds have historically been one of several mechanisms by which democracies defined and constrained their own electorates. Each expansion of voting rights, whether by gender, race, or age, has followed a similar pattern: initial resistance framed as concerns about competence or readiness, followed by incremental local experiments, followed eventually by broader reform once the fears proved unfounded.

The Voting Rights Act of 1965 in the United States, which targeted racial discrimination in voting access primarily through literacy test bans and federal oversight, is directly relevant to age discussions because it demonstrated that Congress has the authority to act on voting rights when it determines that a class of citizens is being unfairly excluded. The 26th Amendment six years later extended this logic to age.

Territorial Exceptions and Partial-Suffrage Models

Some of the most interesting voting age policies exist not in independent nations but in territories, crown dependencies, and autonomous regions. The Isle of Man, a self-governing British Crown Dependency in the Irish Sea, lowered its voting age to 16 in 2006, making it one of the earliest jurisdictions in the world to do so. Jersey and Guernsey, also Crown Dependencies, followed with similar reforms.

Greenland and the Faroe Islands, autonomous territories of Denmark, both use the Danish national voting age of 18, despite having their own parliaments. Puerto Rico, a U.S. territory, is bound by the 26th Amendment threshold of 18 for all elections.

The Scottish Independence Referendum of 2014 was the first UK-wide vote to use 16 as a minimum age, a decision made by the Scottish Parliament under powers granted by the Edinburgh Agreement signed between the UK government and the Scottish Government in 2012. This agreement between then-UK Prime Minister David Cameron and then-Scottish First Minister Alex Salmond specifically authorized Scotland to set its own voting age for that referendum.

The 2021 Scottish Parliament election and subsequent elections have continued to use 16 as the minimum age under the Scottish Elections (Reduction of Voting Age) Act 2015, cementing the policy as a permanent feature of Scottish democracy rather than a one-time exception.

Other Notable Territorial Arrangements

New Caledonia, a French special collectivity in the Pacific, held a series of independence referendums in 2018, 2020, and 2021 under its own electoral rules, which maintained 18 as the minimum voting age but used a highly restricted electoral roll that excluded many newer residents. The New Caledonian case demonstrates that voting age is just one of many levers by which electoral eligibility can be shaped.

Hong Kong, before its 2020-2021 electoral reforms imposed by Beijing following the pro-democracy protests of 2019 and 2020, used a voting age of 18 for its Legislative Council elections. The electoral reforms fundamentally changed the composition of the legislature and reduced the number of directly elected seats, making the voting age question largely secondary in terms of meaningful political impact.

Taiwan maintains 20 as its voting age, one of the higher thresholds among functioning East Asian democracies, though reform proposals to lower it to 18 have been introduced in the Legislative Yuan, Taiwan’s parliament.

The Future Trajectory: Which Countries Are Most Likely to Change Next

Based on legislative activity, citizens’ assembly recommendations, court rulings, and active political movements, several countries appear positioned to lower their voting ages in the near to medium term.

Ireland is among the most likely near-term movers, given the explicit recommendation of the 2022 Citizens’ Assembly and the government’s commitment to respond to assembly recommendations through formal legislative processes.

New Zealand faces judicial pressure following the 2022 Supreme Court ruling that the current 18 threshold is inconsistent with the New Zealand Bill of Rights Act. While the ruling is not technically binding on Parliament due to New Zealand’s parliamentary sovereignty, it creates significant political pressure for action.

Chile was in the process of drafting a new constitution in 2022, and the initial draft proposed by the Constitutional Convention included 16 as the voting age. That draft constitution was rejected in a September 2022 referendum, and a second constitutional process produced a different draft that also did not advance. Chile’s voting age debate remains active but unresolved.

Denmark, Finland, and the Netherlands all have active parliamentary caucuses supporting a lower voting age, with the main barrier being majority coalition support rather than fundamental constitutional obstacles.

England remains the most notable holdout within the British Isles. With Scotland and Wales both at 16 for devolved elections, pressure on the Westminster Parliament to extend 16-year-old voting to UK-wide general elections has grown, though the current political composition of the House of Commons as of writing does not reflect a majority in favor of the change.

Germany’s extension to EU Parliament elections in 2024 may serve as a proving ground for eventual federal election extension. If 16-year-old turnout in EU Parliament elections is comparable to adult turnout, the data argument for extending the right to Bundestag (federal parliament) elections will strengthen considerably.

Voting age policy represents one of the most active frontiers in global electoral law. From the spectacular youth turnout in Scotland’s independence referendum to Japan’s consequential decision to add 2.4 million new voters by lowering the age from 20 to 18, nations continue to reassess what age meaningfully marks the beginning of civic participation. The United States, holding firm at 18 federally while watching cities like Takoma Park and Washington, D.C. experiment at the local level, occupies a middle position in this evolving global landscape. Court rulings in New Zealand, citizens’ assembly recommendations in Ireland, and the EU Parliament’s explicit call for 16-year-old voting across its member states collectively signal that the pressure on the 18 threshold is not easing. Whether the next generation of American policymakers will follow Austria, Scotland, Brazil, and now Germany into broader youth enfranchisement remains one of the genuinely open questions in American democratic development.

FAQs

What is the most common voting age in the world?

The most common minimum voting age worldwide is 18, used by the majority of nations including the United States, Canada, Australia, India, France, and most of Europe. This threshold became globally dominant in the second half of the 20th century as many countries replaced older thresholds of 21.

What countries let 16-year-olds vote?

Countries that allow voting at 16 include Austria, Argentina, Brazil, Ecuador, Nicaragua, Cuba, Malta, Scotland (devolved elections), Wales (devolved elections), the Isle of Man, Jersey, and Guernsey, among others. The scope varies from full national elections to local or regional votes only.

Can 16-year-olds vote in the United States?

16-year-olds cannot vote in any federal or state U.S. elections. However, several cities have extended local voting rights to 16-year-olds, including Takoma Park, Maryland in 2013 and Washington, D.C. in 2023, making DC the largest American jurisdiction to adopt this policy.

What age can you vote in Austria?

Austria allows citizens to vote at 16 in all elections, including national parliamentary elections, regional elections, and local elections. Austria extended this right nationwide in 2007, making it the first and for many years only EU member state to grant full national voting rights at 16.

Why is the U.S. voting age 18?

The U.S. voting age was set at 18 by the 26th Amendment, ratified on July 1, 1971. Before this, the federal threshold was 21. The change was driven largely by the argument that young Americans being drafted to fight in the Vietnam War deserved political representation, and was accelerated by the logistical chaos created by the Oregon v. Mitchell Supreme Court decision of 1970.

What is the voting age in the UK?

The voting age in the United Kingdom is 18 for UK-wide general elections. However, Scotland and Wales allow citizens as young as 16 to vote in their devolved parliamentary elections, creating a split system within the same country. The Isle of Man, Jersey, and Guernsey, which are Crown Dependencies rather than part of the UK itself, all use 16.

Which country has the lowest voting age in the world?

The lowest national voting age for most elections is 16, shared by countries including Austria, Argentina, Brazil, Malta, Nicaragua, and Cuba. Iran held a voting age of 15 briefly following its 1980 Islamic Revolution before raising it back to 16 and then to 18 by 2007. No country currently maintains a national voting age below 16 for general democratic elections.

What is the voting age in Brazil?

Brazil allows citizens aged 16 and 17 to vote on a voluntary, meaning optional, basis under its 1988 constitution. Once a Brazilian citizen turns 18, voting becomes mandatory under Brazilian law, with fines and restrictions on accessing government services for eligible voters who fail to participate without a valid excuse.

Did Japan lower its voting age?

Yes. Japan lowered its voting age from 20 to 18 in 2016, adding approximately 2.4 million new eligible voters to its electorate. This was the first change to Japan’s voting age in over 50 years, passed with broad cross-party support through Japan’s National Diet, and was partly motivated by concerns about the growing electoral dominance of older voters in Japan’s rapidly aging population.

What is the voting age in Germany?

Germany’s federal voting age is 18, but several German states, including Brandenburg, Bremen, and Hamburg, allow 16-year-olds to vote in state parliament elections. Beginning with the 2024 European Parliament elections, Germany extended voting rights to 16-year-olds for those elections, significantly expanding youth political participation.

What is the voting age in Canada?

The minimum voting age in Canada is 18 for federal elections, lowered from 21 by the Canada Elections Act amendment of 1970. All provincial elections also use 18 as the minimum. Canada has not formally moved toward lowering this threshold at the national level, though youth civic organizations have raised the issue periodically.

What is the voting age in Australia?

Australia sets its voting age at 18 and enforces compulsory voting, meaning eligible citizens are legally required to cast a ballot or face a fine starting at approximately $20 AUD for a first offense, administered by the Australian Electoral Commission. This system produces national turnout rates consistently above 90% in federal elections.

Can you vote at 17 in any country?

Yes. Countries with a voting age of 17 include Timor-Leste, Indonesia (or younger if married), North Korea, and Greece, which lowered its threshold from 18 to 17 in 2016 for all elections. This age threshold is less common than either 16 or 18 and in some cases reflects specific constitutional rather than deliberate youth enfranchisement decisions.

What was the Scottish voting age in the 2014 independence referendum?

The 2014 Scottish Independence Referendum used a minimum voting age of 16, the first time that threshold was applied to any UK-wide vote. Turnout among 16 and 17-year-old Scottish voters was approximately 75%, higher than the turnout rate among voters aged 18 to 24 nationally and widely cited as evidence that 16-year-olds engage meaningfully when given the opportunity to vote.

What is the voting age in Mexico?

Mexico sets its national voting age at 18. Citizens must register with the Instituto Nacional Electoral (National Electoral Institute) and obtain a credencial para votar (voter credential card) to participate. Mexico has not moved toward lowering the voting age, and 18 remains the uniform threshold across all election types at federal, state, and municipal levels.

How many countries have compulsory voting?

Approximately 27 countries enforce compulsory voting in some form, according to International IDEA, the International Institute for Democracy and Electoral Assistance, founded in Stockholm in 1995. Notable examples include Australia, Brazil, Argentina, Belgium, Luxembourg, Ecuador, Bolivia, Peru, and Uruguay, with varying penalty structures from small fines to restrictions on accessing government services.

Is there a push to lower the U.S. voting age to 16?

Yes. Organizations including the National Youth Rights Association have actively campaigned for a lower federal voting age, and individual members of Congress have introduced constitutional amendment proposals. Washington, D.C. passed legislation in 2023 lowering the local voting age to 16, making it the largest U.S. jurisdiction to adopt the policy. No federal proposal has passed a committee vote, reflecting the significant constitutional barriers involved.

What did the 26th Amendment change?

The 26th Amendment to the U.S. Constitution, ratified on July 1, 1971, lowered the federal voting age from 21 to 18. It was ratified faster than any other constitutional amendment in U.S. history, taking only 100 days from congressional approval to ratification by the required 38 states, reflecting broad national consensus that the old threshold was indefensible during the Vietnam War draft era.

What is the voting age in India?

India sets its voting age at 18, lowered from 21 by the 61st Constitutional Amendment Act of 1988, which took effect in time for the 1989 general elections. This single change added tens of millions of new eligible voters to the world’s largest democracy in a single policy action, one of the largest single expansions of the franchise in any country’s history.

Do 16-year-olds vote in Argentina?

Yes. Argentina allows citizens aged 16 and 17 to vote on a voluntary basis in all national, provincial, and local elections under legislation passed in 2012. Once Argentine citizens reach 18, voting becomes compulsory, creating a deliberate two-stage design where young voters opt in before the legal obligation activates.

What is the voting age in France?

France maintains a voting age of 18 for all elections, including presidential, legislative, regional, and local contests. The French voting age was lowered from 21 to 18 in 1974 under President Valéry Giscard d’Estaing. France does not currently provide for 16-year-old voting in any jurisdiction, and there is no active legislative movement to change this threshold.

What countries are most likely to lower their voting age next?

Based on current political activity, Ireland is among the most likely near-term movers following its 2022 Citizens’ Assembly recommendation. New Zealand faces judicial pressure after a 2022 Supreme Court ruling found the 18 threshold inconsistent with the New Zealand Bill of Rights Act. Denmark, Finland, England, and Chile also have active movements toward a lower threshold, with the main barrier in each case being majority political support rather than fundamental constitutional obstacles.
