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

We won't have anything like a definitive assessment of 2020 turnout rates for some time after Nov. 3. But in the 2016 presidential ballot, nearly 56% of the U.Due south. voting-historic period population cast a election. That represented a slight uptick from 2012 but was lower than in the record yr of 2008, when turnout topped 58% of the voting-age population.

So how does voter turnout in the United states of america compare with turnout in other countries? That depends very much on which country y'all're looking at and which measuring stick y'all employ.

Political scientists oft ascertain turnout every bit votes bandage divided by the number of eligible voters. Simply considering eligible-voter estimates are non readily bachelor for many countries, we're basing our cantankerous-national turnout comparisons on estimates of voting-age population (or VAP), which are more readily bachelor, too as on registered voters. (Read "How we did this" for details.)

Comparison U.S. national election turnout rates with rates in other countries can yield different results, depending on how turnout is calculated. Political scientists oftentimes ascertain turnout as votes cast divided past the estimated number of eligible voters. Merely eligible-voter estimates are difficult or incommunicable to find for many nations. So to compare turnout calculations internationally, we're using two different denominators: total registered voters and estimated voting-age populations, or VAP, because they're readily available for most countries.

We calculated turnout rates for the most recent national ballot in each country, except in cases where that election was for a largely ceremonial position or for European Parliament members (turnout is often substantially lower in such elections). Voting-age population turnout is derived from estimates of each country's VAP by the International Institute for Democracy and Electoral Assist. Registered-voter turnout is derived from each country's reported registration data. Because of methodological differences, in some countries IDEA's VAP estimates are lower than the reported number of registered voters.

In add-on to information from Idea, information is likewise drawn from the U.S. Census Bureau, the Role of the Clerk of the U.S. Business firm of Representatives, and individual nations' statistical and election authorities.

Overall, 245.five one thousand thousand Americans were ages 18 and older in November 2016, most 157.six one thousand thousand of whom reported being registered to vote, according to Census Bureau estimates. Just over 137.5 1000000 people told the demography they voted that yr, somewhat college than the actual number of votes tallied – almost 136.eight 1000000, according to figures compiled by the Office of the Clerk of the U.Southward. Business firm of Representatives (which include more than than 170,000 blank, spoiled or otherwise goose egg ballots). That sort of overstatement has long been noted past researchers; the comparisons and charts in this analysis utilise the House Clerk'due south figure, forth with data from the International Constitute for Democracy and Electoral Help and private nations' statistical and elections authorities.

The 55.7% VAP turnout in 2016 puts the U.Due south. backside near of its peers in the System for Economic Cooperation and Development, most of whose members are highly developed autonomous states. Looking at the well-nigh recent nationwide ballot in each OECD nation, the U.S. places 30th out of 35 nations for which data is bachelor.

Pew Research Middle

The highest turnout rates among OECD nations were in Turkey (89% of voting-age population), Sweden (82.1%), Australia (fourscore.8%), Belgium (77.ix%) and South Korea (77.9%). Switzerland consistently has the everyman turnout in the OECD: In 2019 federal elections, barely 36% of the Swiss voting-age population voted.

Ane factor behind the consistently high turnout rates in Commonwealth of australia and Belgium may exist that they are among the 21 nations around the world, including six in the OECD, with some form of compulsory voting. One canton in Switzerland has compulsory voting every bit well.

While compulsory-voting laws aren't e'er strictly enforced, their presence or absence tin have dramatic effects on turnout. In Chile, for example, turnout plunged afterward the state 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's 2013 elections, turnout in the presidential race plunged to 42%, versus 87% in 2010 when the compulsory-voting law was nonetheless in identify. (Turnout rebounded slightly in the 2017 presidential ballot, to 49% of registered voters.)

Chile's state of affairs points to yet another complicating cistron when comparison turnout rates across countries: the distinction between who'south eligible to vote and who's actually registered to practise so. In many countries, the national regime takes the lead in getting people'southward names on the rolls – whether by registering them automatically once they become eligible (as in, for example, Sweden or Germany) or past aggressively seeking out and registering eligible voters (every bit in the Uk and Australia). Every bit a upshot, turnout looks pretty like regardless of whether you're looking at voting-age population or registered voters.

In the U.S., past 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 Census Bureau. The U.S. rate is much lower than many other OECD countries: For instance, 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). Luxembourg also has a low rate (54%), although information technology represents something of a special case considering nearly half of the tiny state's 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.viii% of registered voters, fifth-highest among OECD countries and second-highest among those without compulsory voting. Just registered voters in the U.Southward. are much more of a self-selected group, already more than probable to vote because they took the trouble to register themselves.

There are even more means to calculate turnout. Michael McDonald, a political scientist at the Academy of Florida who runs the United States Election Project, estimates turnout every bit 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. However, McDonald doesn't calculate comparable estimates for other countries.

No thing how they're measured, U.Southward. turnout rates take been fairly consistent over the by several decades, despite some election-to-election variation. Since 1976, voting-historic period turnout has remained inside an 8.five percent bespeak range – from only under l% in 1996, when Bill Clinton was reelected, to but over 58% in 2008, when Barack Obama won the White House. However, turnout varies considerably among unlike 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'southward not enforced; turnout in that location in parliamentary elections savage from 89% in 2000 to 63.five% last year. In Norway's most recent parliamentary elections, 2017, seventy.half-dozen% of the voting-age population cast ballots – the everyman turnout rate in at least four decades. And in Slovenia, a flare-up of enthusiasm followed the state's independence from Yugoslavia in 1992, when 85% of the voting-age population cast ballots – but turnout has fallen virtually 31 pct points in two-and-a-one-half decades of commonwealth, sinking to 54.6% in 2018.

On the other hand, turnout in contempo elections has bumped up in several OECD countries. Canadian turnout in the two most contempo parliamentary elections (2015 and 2019) topped 62%, the highest rate since 1993. In Slovakia'due south legislative elections this by Feb, most 2-thirds (65.four%) of the voting-age population bandage ballots, up from 59.4% in 2016. And in Hungary's 2018 parliamentary elections, nearly 72% of the voting-age population voted, up from 63.three% in 2014.
