More than 40 countries and over 1.5 billion people will vote in 2026 alone, but no two democracies run their elections the same way. From first-past-the-post ballots to party lists and compulsory voting laws, here's how the machinery of democracy actually works — and what the latest global data reveals about its health.
Elections are the closest thing the modern world has to a universal political ritual. Nearly every country on Earth holds them in some form, yet the rules for how a vote becomes a seat in parliament or a presidency vary enormously from one nation to the next. More than 40 countries are expected to hold national elections in 2026, representing over 1.5 billion people worldwide, making it another pivotal year for democracy across the globe. This piece breaks down the major electoral systems in use, how many countries rely on each, how turnout is changing, and what the latest global democracy data actually shows.
The Two Big Families of Electoral Systems
Nearly every national electoral system in the world falls into one of two broad camps, majoritarian systems, where the candidate or party with the most votes wins outright, and proportional systems, where seats are distributed to roughly match a party's share of the vote.
First-Past-the-Post and Majoritarian Systems
The best-known majoritarian model is first-past-the-post (FPTP), used in single-member constituencies where the candidate with the most votes wins, regardless of whether they secure an outright majority.Less than 55 countries use the first-past-the-post system today, a minority of countries globally, one of which is the United Kingdom, and those who still use it tend to have inherited it as former British colonies.
Proportional Representation Is the Global Norm
Contrary to how prominently FPTP features in English-language media, it is not the world's dominant model. There are over 130 countries which use either a proportional representation or a mixed system to elect their lower chamber, making proportional representation the most popular form of electoral democracy today. Under party-list PR systems, voters choose between party lists rather than individual candidates in multi-member constituencies, with seats allocated to reflect each party's overall vote share, these lists can be "closed," where the party sets a fixed order of candidates, or "open," letting voters pick individual names from the list.
A smaller number of countries, including Ireland and Malta, use the Single Transferable Vote, a preferential form of PR in multi-member districts, while others blend the two big families through Mixed Member Proportional systems. MMP combines a first-past-the-post element for a local representative with a party-list ballot that tops up seats to make the overall parliament proportional, and is used in systems such as Scotland's devolved parliament.
Why the System Matters
The choice of electoral system is not a neutral technicality, it shapes which parties can realistically win seats and how governments are formed. Notably, index of the top ten countries on the 2024 Human Freedom Index use a form of proportional representation, and the same is true of nine of the ten countries rated "full democracies" that year, a group that includes Norway, New Zealand and Iceland. This correlation doesn't prove PR causes better governance outcomes, but it is one of the most-cited data points in debates over electoral reform.
The State of Global Democracy: What the 2025 Data Shows
Understanding how elections are run is only half the picture; understanding how free and fair they are is the other. The Economist Intelligence Unit's Democracy Index, which scores 167 countries and territories across five categories, is the most widely used benchmark.
After nearly a decade of erosion, the picture stabilized in 2025. The number of countries classified as full or flawed democracies rose from 77 to 80, while hybrid and authoritarian regimes fell from 90 to 87, with the global average score rising by 0.02 points, one of the largest year-on-year increases since 2012.The EIU reported that almost three-quarters of countries either improved their score or held steady between 2024 and 2025.
Even so, the overall balance remains tilted toward non-democratic governance. Authoritarian regimes govern the largest share of the world's population at 39.2%, while flawed democracies form the second-largest category by both country count (48) and population share (38.4%). Full democracies, by contrast, remain a small club anchored by a familiar set of names.Norway, Denmark, Iceland, Finland and Sweden hold the top ranking positions, with New Zealand in second place overall.
Movement in and out of categories tells its own story. Of the seven countries that changed regime classification in 2025, five moved toward democracy, France returned to "full democracy" status, while Romania, Malawi, Senegal and Paraguay were upgraded to "flawed democracy", while Moldova slipped into the hybrid category and Angola became newly classified as authoritarian. The United States moved the opposite direction.Its score fell by 0.2 points to 7.65, pushing it down six places to 34th in the global ranking, driven by the EIU's assessment of a weakening functioning of government and civil liberties.
Voter Turnout: A Six-Decade Decline
Electoral systems only matter if people actually vote, and on that front the global trend has been heading in one direction for a generation. Global voter turnout was fairly stable from the 1940s through the 1980s, slipping only slightly from 78% to 76%, before falling sharply in the 1990s to 70% and continuing its decline to around 66% since.Most countries today post lower turnout than they did 20 to 30 years ago, a trend election researchers attribute to multiple overlapping causes.
Regional patterns vary sharply. Africa has recorded the lowest average turnout of any region across the entire period tracked since the 1950s. At the other extreme, a handful of small island nations post remarkably high figures.Antigua and Barbuda and Nauru have both recorded turnout above 90% in recent elections. But high turnout numbers can mask serious problems,Rwanda has posted some of the world's highest recorded turnout figures even as watchdog group Freedom House rates its elections as marred by irregularities, including restricted candidate eligibility and unfair registration practices. High turnout, in other words, is not automatically evidence of a healthy democracy.
The United States illustrates how turnout can swing significantly even within a single democracy. In the 2024 presidential election, roughly 154 million Americans voted, representing 65.3% of the citizen voting-age population, a decline from 70.75% turnout in 2020, though still well above the 55.7% recorded in 2016.
Compulsory Voting: Forcing the Turnout Question
A minority of countries have tried to reverse the turnout decline through law rather than persuasion, by making voting a legal obligation. As of 2026, roughly 22 countries actively enforce compulsory voting laws, though the exact count depends on how strictly "enforcement" is defined, since some countries keep the law on the books but rarely apply penalties.
Belgium holds the oldest continuously operating compulsory voting system, introduced for men in 1893 and extended to women in 1948, while Australia adopted compulsory voting for federal elections in 1924. The effect on turnout can be dramatic,voluntary voting in Australia before 1924 produced turnout between 47% and 78%, but after the law took effect turnout jumped to between 91% and 96%.
Enforcement, however, is inconsistent worldwide. As of January 2020, Australia was the only OECD member state actually enforcing compulsory voting in practice, while voting remained compulsory in law but unenforced in Belgium, Greece, Luxembourg, Mexico and Turkey.Some countries have gone further, tying non-compliance to real civic consequences, in Belgium, citizens who fail to vote in at least four elections within a 15-year period can face disenfranchisement.
The debate over whether compulsion is good for democracy remains unresolved. Proponents argue it produces a more representative electorate and blunts the appeal of narrowly focused populist movements, while critics counter that it compels political speech and tends to raise the number of blank or spoiled ballots rather than genuine engagement.
2026: A Landmark Year for Elections
The current year is unusually dense with major national votes. Among the most closely watched contests are the U.S. midterm elections in November, which will determine control of Congress, and Brazil's general election in October, where voters will elect a president, legislature and state governments.In Europe, Hungary's April election tested Prime Minister Viktor Orbán's long hold on power, while Israel is set to hold a closely contested legislative election by October against a backdrop of ongoing regional tensions.
Each of these votes will be run under a different rulebook, Hungary's mixed-member system, Brazil's open-list proportional representation with mandatory voting, Israel's nationwide party-list PR, and America's state-by-state, largely first-past-the-post framework layered under the Electoral College. That patchwork is, in miniature, the story of global elections: a shared democratic instinct expressed through dozens of different mechanical designs, each with its own trade-offs between representation, stability and simplicity.
The Bottom Line
No single electoral system has "won" globally, proportional representation dominates by country count, first-past-the-post persists mainly in Britain's former colonies, and a small but resilient group of nations still compel their citizens to the polls by law. What the data makes clear is that the mechanics of voting and the health of democracy are two separate questions: a country can have high turnout and weak democratic institutions, or low turnout and strong ones. As 2026's wave of elections plays out across more than 40 countries, both dimensions, how people vote, and how freely they are able to — will remain the two metrics worth watching most closely.
