Legal Voting Age by Country: A Global Overview The voting age is the minimum age at which a citizen can legally cast a ballot in a public election. This benchmark varies significantly across nations, reflecting diverse historical, social, and political contexts. While a global consensus has emerged around age 18, notable exceptions exist at both lower and higher thresholds, shaping electoral participation worldwide. Most Countries Set Voting Age at 18 Today, approximately 85% of the world’s countries and territories establish 18 as the legal voting age. This standard gained widespread adoption between 1965 and 1975, replacing the previously common threshold of 21. Key milestones included the United Kingdom lowering its voting age from 21 to 18 in 1969, Canada following in 1970, and the United States ratifying the 26th Amendment in 1971—largely driven by the argument that those old enough to be drafted for military service should have the right to vote. More recently, Japan reduced its national voting age from 20 to 18 in 2016, South Korea made the same change in 2020 (from 19 to 18), and Malaysia transitioned from 21 to 18 in 2019, with implementation in 2021. Countries Allowing Voting at Age 16 A smaller group of nations permits voting at 16, often for specific elections or under certain conditions. These include Austria, Brazil, Cuba, Ecuador, Nicaragua, and Malta. In Wales, 16- and 17-year-olds can vote in Welsh parliamentary and local elections. Argentina as well allows voting at 16, though voting becomes mandatory from age 18. Ecuador mandates voting for citizens aged 18 to 65, while Brazil and Argentina require voting for those between 18 and 70. Some regions, such as Jersey and the Isle of Man, similarly extend suffrage to 16-year-olds in local elections. Nations with Voting Age of 17 A limited number of countries set the voting age at 17. These include Greece, Indonesia, and North Korea. In Indonesia, married individuals may vote regardless of age, effectively lowering the threshold for that demographic. Greece allows voting at 17 in national elections, reflecting a midpoint between the global standard and youth suffrage advocates’ proposals. Countries with Higher Voting Ages A minority of states maintain voting ages above 18. The Solomon Islands is the sole nation where the voting age is 19. Taiwan is among four countries—alongside others not specified in the primary sources—where citizens must reach age 20 to vote. Several states, including Kuwait, Singapore, Oman, and Samoa, set the threshold at 21. The United Arab Emirates holds the highest voting age globally at 25, a distinction attributed to its specific electoral framework and citizenship requirements. Special Rules and Restrictions Many countries apply nuanced rules beyond a uniform national age. Some permit younger voting in local or regional elections while maintaining higher thresholds for national contests. Others impose compulsory voting within certain age brackets, as seen in Argentina, Brazil, and Ecuador. Additional distinctions may apply based on marital status, employment, or military service. For example, in some Balkan nations, employed 16-year-olds may vote despite not meeting the general age requirement. These variations often reflect local customs, historical practices, or efforts to balance civic engagement with perceived maturity for electoral participation. Ongoing Debates and Trends Discussions about lowering the voting age persist in numerous democracies, driven by arguments that youth are sufficiently informed and affected by policy decisions to warrant earlier enfranchisement. Conversely, proponents of higher ages cite concerns about political maturity and life experience. As of 2026, the global trend remains toward inclusivity, with more countries considering reforms to expand youth voting rights—particularly at the subnational level—while a small contingent retains higher thresholds rooted in tradition or institutional design. Understanding the voting age worldwide offers insight into how nations conceptualize citizenship, responsibility, and democratic participation. While age 18 stands as the prevailing benchmark, the diversity of approaches underscores that electoral rights are shaped not only by universal principles but also by unique national trajectories.
