If early on voting trends are any indication, a tape number of Americans could vote in the 2020 presidential election. As of this writing, more than 100 million early votes take been cast by mail or in person – more than 2-thirds of the full number of votes bandage in 2016.

We won't have annihilation like a definitive cess of 2020 turnout rates for some time afterward Nov. 3. But in the 2016 presidential ballot, well-nigh 56% of the U.Southward. voting-age population cast a ballot. That represented a slight uptick from 2012 just was lower than in the tape year of 2008, when turnout topped 58% of the voting-age population.

And then how does voter turnout in the United States compare with turnout in other countries? That depends very much on which state you're looking at and which measuring stick y'all use.

Political scientists often define turnout every bit votes cast divided past the number of eligible voters. But because eligible-voter estimates are not readily available for many countries, we're basing our cross-national turnout comparisons on estimates of voting-age population (or VAP), which are more than readily bachelor, too every bit on registered voters. (Read "How we did this" for details.)

Comparing U.S. national election turnout rates with rates in other countries can yield different results, depending on how turnout is calculated. Political scientists often define turnout as votes cast divided by the estimated number of eligible voters. Merely eligible-voter estimates are hard or impossible to find for many nations. And so to compare turnout calculations internationally, we're using two different denominators: total registered voters and estimated voting-age populations, or VAP, considering they're readily bachelor for well-nigh countries.

We calculated turnout rates for the well-nigh contempo national ballot in each country, except in cases where that ballot was for a largely ceremonial position or for European Parliament members (turnout is oft substantially lower in such elections). Voting-age population turnout is derived from estimates of each country's VAP by the International Plant for Republic and Electoral Assistance. Registered-voter turnout is derived from each land'due south reported registration data. Because of methodological differences, in some countries Idea's VAP estimates are lower than the reported number of registered voters.

In addition to information from Idea, data is likewise fatigued from the U.Southward. Census Bureau, the Part of the Clerk of the U.Southward. House of Representatives, and private nations' statistical and election authorities.

Overall, 245.v 1000000 Americans were ages eighteen and older in November 2016, about 157.six one thousand thousand of whom reported being registered to vote, according to Demography Agency estimates. Just over 137.5 1000000 people told the census they voted that year, somewhat college than the actual number of votes tallied – nearly 136.8 1000000, according to figures compiled by the Office of the Clerk of the U.S. Firm of Representatives (which include more than 170,000 blank, spoiled or otherwise zilch ballots). That sort of overstatement has long been noted past researchers; the comparisons and charts in this analysis utilise the House Clerk's effigy, forth with data from the International Institute for Democracy and Electoral Assistance and individual nations' statistical and elections authorities.

The 55.7% VAP turnout in 2016 puts the U.S. backside near of its peers in the Organisation for Economic Cooperation and Development, most of whose members are highly developed democratic states. Looking at the most recent nationwide election in each OECD nation, the U.Southward. places 30th out of 35 nations for which data is bachelor.

The highest turnout rates among OECD nations were in Turkey (89% of voting-age population), Sweden (82.1%), Australia (lxxx.8%), Belgium (77.9%) and Republic of korea (77.9%). Switzerland consistently has the lowest turnout in the OECD: In 2019 federal elections, barely 36% of the Swiss voting-age population voted.

One cistron behind the consistently high turnout rates in Australia and Belgium may be that they are among the 21 nations around the earth, including six in the OECD, with some form of compulsory voting. One county in Switzerland has compulsory voting besides.

While compulsory-voting laws aren't ever strictly enforced, their presence or absenteeism tin can accept dramatic furnishings on turnout. In Chile, for example, turnout plunged later on the country moved from compulsory to voluntary voting in 2012 and began automatically putting all eligible citizens on the voter rolls. Even though essentially all voting-age citizens were registered to vote in Chile'due south 2013 elections, turnout in the presidential race plunged to 42%, versus 87% in 2010 when the compulsory-voting law was however in place. (Turnout rebounded slightly in the 2017 presidential election, to 49% of registered voters.)

Republic of chile's state of affairs points to still another complicating cistron when comparing turnout rates across countries: the distinction between who's eligible to vote and who'due south actually registered to practice and so. In many countries, the national government takes the lead in getting people's names on the rolls – whether past registering them automatically once they become eligible (as in, for example, Sweden or Germany) or by aggressively seeking out and registering eligible voters (equally in the Great britain and Australia). Equally a outcome, turnout looks pretty similar regardless of whether you're looking at voting-age population or registered voters.

In the U.S., by dissimilarity, registration is decentralized and mainly an individual responsibility. And registered voters represent a much smaller share of potential voters in the U.S. than in many other countries. Only about 64% of the U.S. voting-age population (and 70% of voting-age citizens) was registered in 2016, according to the Demography Bureau. The U.S. charge per unit is much lower than many other OECD countries: For example, the share of the voting-historic period population that is registered to vote is 92% in the UK (2019), 93% in Canada (2019), 94% in Sweden (2018) and 99% in Slovakia (2020). Grand duchy of luxembourg besides has a low rate (54%), although it represents something of a special instance because nearly half of the tiny land'southward population is foreign born.

Turnout in U.S. presidential elections

As a consequence, turnout comparisons based only on registered voters may not be very meaningful. For instance, U.S. turnout in 2016 was 86.8% of registered voters, fifth-highest among OECD countries and second-highest among those without compulsory voting. Merely registered voters in the U.S. are much more of a cocky-selected grouping, already more likely to vote because they took the trouble to register themselves.

There are fifty-fifty more than ways to calculate turnout. Michael McDonald, a political scientist at the University of Florida who runs the United States Ballot Project, estimates turnout equally a share of the "voting-eligible population" by subtracting noncitizens and ineligible felons from the voting-age population and adding eligible overseas voters. Using those calculations, U.S. turnout improves somewhat, to 60.1% of the 2016 voting-eligible population. Nonetheless, McDonald doesn't calculate comparable estimates for other countries.

No thing how they're measured, U.S. turnout rates have been fairly consistent over the past several decades, despite some election-to-election variation. Since 1976, voting-historic period turnout has remained within an eight.five percentage point range – from just under 50% in 1996, when Pecker Clinton was reelected, to just over 58% in 2008, when Barack Obama won the White Business firm. However, turnout varies considerably among different racial, ethnic and age groups.

In several other OECD countries, turnout has drifted lower in recent decades. Greece has a compulsory-voting law on the books, though it'south not enforced; turnout there in parliamentary elections fell from 89% in 2000 to 63.5% last year. In Norway's most recent parliamentary elections, 2017, 70.6% of the voting-historic period population cast ballots – the lowest turnout rate in at least 4 decades. And in Slovenia, a burst of enthusiasm followed the country'south independence from Yugoslavia in 1992, when 85% of the voting-historic period population bandage ballots – but turnout has fallen most 31 per centum points in two-and-a-half decades of democracy, sinking to 54.6% in 2018.

On the other hand, turnout in contempo elections has bumped upwards in several OECD countries. Canadian turnout in the two most recent parliamentary elections (2015 and 2019) topped 62%, the highest rate since 1993. In Slovakia'southward legislative elections this past February, nearly 2-thirds (65.4%) of the voting-age population cast ballots, upwardly from 59.iv% in 2016. And in Hungary'due south 2018 parliamentary elections, nearly 72% of the voting-age population voted, upward from 63.3% in 2014.
