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

We won't have anything like a definitive assessment of 2020 turnout rates for some time afterward Nov. 3. Just in the 2016 presidential election, almost 56% of the U.South. voting-age population cast a ballot. That represented a slight uptick from 2012 simply was lower than in the record year of 2008, when turnout topped 58% of the voting-age population.

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

Political scientists frequently define turnout as votes cast divided by 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-historic period population (or VAP), which are more than readily available, likewise every bit on registered voters. (Read "How we did this" for details.)

Comparing U.S. national ballot turnout rates with rates in other countries can yield different results, depending on how turnout is calculated. Political scientists oft define turnout equally votes cast divided past the estimated number of eligible voters. But eligible-voter estimates are difficult or incommunicable to find for many nations. And so to compare turnout calculations internationally, nosotros're using two dissimilar denominators: total registered voters and estimated voting-age populations, or VAP, considering they're readily available for most countries.

We calculated turnout rates for the nearly 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 ofttimes substantially lower in such elections). Voting-age population turnout is derived from estimates of each country'south VAP by the International Institute for Democracy and Electoral Assist. Registered-voter turnout is derived from each land'south reported registration information. Because of methodological differences, in some countries IDEA'south VAP estimates are lower than the reported number of registered voters.

In addition to data from Thought, data is too drawn from the U.South. Census Bureau, the Office of the Clerk of the U.S. House of Representatives, and individual nations' statistical and election authorities.

Overall, 245.5 meg Americans were ages 18 and older in Nov 2016, virtually 157.6 meg of whom reported existence registered to vote, according to Demography Bureau estimates. Just over 137.5 meg people told the census they voted that year, somewhat higher than the actual number of votes tallied – nearly 136.8 million, according to figures compiled past the Office of the Clerk of the U.South. House of Representatives (which include more than 170,000 blank, spoiled or otherwise null ballots). That sort of overstatement has long been noted by researchers; the comparisons and charts in this assay use the House Clerk's figure, along with data from the International Plant for Commonwealth and Electoral Help and private nations' statistical and elections authorities.

The 55.7% VAP turnout in 2016 puts the U.South. behind nigh of its peers in the Organization for Economic Cooperation and Evolution, most of whose members are highly developed democratic states. Looking at the well-nigh recent nationwide election in each OECD nation, the U.S. places 30th out of 35 nations for which data is available.

The highest turnout rates among OECD nations were in Turkey (89% of voting-age population), Sweden (82.ane%), Commonwealth of australia (eighty.8%), Belgium (77.9%) and South 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 factor behind the consistently high turnout rates in Australia and Belgium may be that they are among the 21 nations around the world, including half-dozen in the OECD, with some course of compulsory voting. One canton in Switzerland has compulsory voting as well.

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

Chile's situation points to yet another complicating factor when comparing turnout rates across countries: the distinction between who'southward eligible to vote and who'southward actually registered to practise so. In many countries, the national regime takes the pb in getting people's names on the rolls – whether past registering them automatically once they become eligible (as in, for case, Sweden or Frg) or by aggressively seeking out and registering eligible voters (as in the UK and Australia). As a result, turnout looks pretty like regardless of whether you're looking at voting-historic period population or registered voters.

In the U.S., by contrast, registration is decentralized and mainly an individual responsibility. And registered voters correspond a much smaller share of potential voters in the U.South. 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.South. rate is much lower than many other OECD countries: For example, the share of the voting-age 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 it represents something of a special case considering almost half of the tiny country's population is foreign built-in.

Turnout in U.S. presidential elections

As a consequence, turnout comparisons based only on registered voters may not exist very meaningful. For instance, U.Due south. turnout in 2016 was 86.viii% of registered voters, fifth-highest amongst OECD countries and 2d-highest among those without compulsory voting. But registered voters in the U.S. are much more of a self-selected grouping, already more than likely to vote because they took the trouble to register themselves.

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

No matter how they're measured, U.South. turnout rates take been fairly consistent over the past several decades, despite some election-to-election variation. Since 1976, voting-age turnout has remained within an 8.5 percentage point range – from just under l% in 1996, when Bill Clinton was reelected, to just over 58% in 2008, when Barack Obama won the White House. Nevertheless, turnout varies considerably among different racial, indigenous and historic period groups.

In several other OECD countries, turnout has drifted lower in recent decades. Greece has a compulsory-voting law on the books, though information technology'south not enforced; turnout in that location in parliamentary elections fell from 89% in 2000 to 63.v% last yr. In Norway's about recent parliamentary elections, 2017, 70.six% of the voting-age population cast ballots – the everyman turnout rate in at least iv decades. And in Slovenia, a burst of enthusiasm followed the state'south independence from Yugoslavia in 1992, when 85% of the voting-age population cast ballots – but turnout has fallen most 31 percentage points in 2-and-a-half decades of commonwealth, sinking to 54.vi% in 2018.

On the other mitt, turnout in contempo elections has bumped upward in several OECD countries. Canadian turnout in the ii most recent parliamentary elections (2015 and 2019) topped 62%, the highest rate since 1993. In Slovakia'due south legislative elections this by Feb, nearly ii-thirds (65.4%) 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, upwardly from 63.3% in 2014.
