Should voting be compulsory?

Every democratic election produces two results. One is announced on election night: who won. The other is rarely reported, though it shapes everything that follows: who took part. In most countries with voluntary voting, the second result is predictable before a single ballot is cast. Older, wealthier and better-educated citizens vote at higher rates than the young, the poor and the less educated, and the gap tends to widen when overall turnout falls. Elected officials know this, and they govern accordingly.

This is the first and strongest case for compulsory voting. Democracy promises political equality: each citizen’s interests are to count for as much as anyone else’s. Voluntary voting keeps that promise formally while breaking it in practice. A pensioner who votes in every election and a 22-year-old care worker on night shifts have the same right to vote, but only one of them is reliably counted when parties draw up their platforms. A legal duty to turn up narrows that gap more effectively than any registration drive, because it does not depend on the very resources (time, confidence, information, habit) whose unequal distribution produces the gap in the first place.

Australia has required citizens to attend the polls in federal elections since 1924, Belgium since the 1890s. In Australia, turnout has stayed at around nine in ten registered voters for a century, and the socioeconomic skew that dominates turnout elsewhere is much flatter. The penalty is a modest fine, smaller than a parking ticket, and it is rarely pursued against people with a reasonable excuse.

Second, voting has the structure of a public good. The value of a broadly representative electorate does not depend on any single vote, which is exactly why each of us is tempted to leave the work to others. We accept legal duties to solve problems of this shape elsewhere: we pay taxes, we fill in the census, we serve on juries. In each case the burden on any individual is small, the collective benefit is large, and voluntary compliance predictably falls short. It is hard to see why the act that constitutes democratic authority should be the one civic task we leave entirely to inclination.

Third, compulsion changes the incentives of those who seek power. Where turnout is voluntary, campaigns spend a great deal of effort on mobilising their own base and, in less scrupulous cases, on discouraging the other side’s supporters from turning up. When nearly everyone votes, those strategies lose most of their value. Parties must persuade instead. Whether this reduces polarisation is still debated, but it removes one of its engines: the payoff from making politics feel hostile enough that moderate or marginal voters stay home.

The most serious objection is that compulsion violates a right to abstain. I take it seriously, but it misdescribes what a well-designed system requires. The duty is to attend, or to return a postal ballot. It is not a duty to choose a candidate. A citizen can spoil the ballot, leave it blank or, in better designs, tick an explicit “none of the above”. What is compelled is presence, not speech. Abstention as protest remains available. It simply becomes visible and countable, instead of being indistinguishable from apathy, illness or a missed bus.

A second objection holds that compulsion floods the electorate with uninformed voters. There are two replies. The uninformed already vote; the only question is which uninformed citizens are counted. And a duty to vote gives citizens a reason to pay attention that voluntary systems lack. The evidence that compulsory voting worsens the quality of collective decisions is thin. The evidence that voluntary voting skews them toward the advantaged is not.

Finally, some worry that fines will fall hardest on the marginalised. That is a problem of design, not of principle. Exemptions for hardship, automatic enrolment, postal and early voting, and penalties that a reasonable excuse discharges all reduce the burden. A democracy serious about equality should do all of these things anyway. Compulsion simply ensures that, once the barriers are lowered, everyone is actually asked.

Democracy is the claim that political authority belongs to all of us together. A small legal duty to show up is how we make that claim true in practice and not only in principle.

Defenders of compulsory voting describe it as a minor inconvenience: a trip to the polling station once every few years, a ballot you are free to leave blank, a fine smaller than a parking ticket. Put that way, opposing it can look like fussiness about liberty in the face of a real injustice. Turnout really is unequal, and that inequality really does shape whom governments listen to. I do not dispute the problem. I dispute the remedy.

Start with what is being compelled. The usual reply is that the law requires only attendance, not a vote. But a democracy that cannot tolerate a citizen’s absence has changed the meaning of participation. Staying away from an election can be a considered political act: a refusal to lend legitimacy to a contest one regards as rigged, a protest against a party system that offers no real choice, or a conscientious objection rooted in religious or moral conviction. A blank ballot is not the same thing. It must be cast within the very ritual one wishes to refuse, and it is counted, if at all, as a statistical oddity. Compulsion asks dissenters to perform consent in order to register dissent.

Second, the burden of compulsion does not fall evenly. Those most likely to abstain are, by the defenders’ own account, the poor, the young, the precariously employed and those with least reason to trust public institutions. These are the people who will receive the fines, field the enforcement letters and have to explain themselves to officials. For someone with a stable job and a fixed address, a small penalty is trivial. For someone moving between short-term rentals, it can become a debt, and debts compound. Hardship exemptions help, but they demand exactly the bureaucratic competence that the excluded often lack. A policy meant to include the marginalised begins by treating their absence as an offence.

Third, the promised benefits are less secure than they appear. Higher turnout under compulsion is well documented. Large and reliable changes in policy outcomes are not. Studies of its effects on redistribution and on party systems yield mixed results, and countries with different turnout rules arrive at similar policies while countries with similar rules diverge. If the goal is a government that responds to the interests of the disadvantaged, turnout is one input among many, alongside the structure of parties, the strength of unions and civic organisations, and the role of money in campaigns. Compulsion targets the most visible symptom of unequal influence, not its causes.

Fourth, low turnout carries information. When large parts of the population stop voting, that is a signal that the political system is failing to represent them, and a democracy needs that signal to stay legible. Compulsion erases it. It produces an electorate that looks complete while leaving untouched the reasons people had for walking away. Governments can then claim a mandate from citizens who were legally required to appear and whose alienation now shows up nowhere in the numbers.

None of this means accepting unequal turnout as a fact of nature. We know a great deal about what lowers the cost of voting: automatic and permanent registration, elections on weekends or public holidays, generous postal and early voting, polling stations where people actually live, and civic education that begins well before eighteen. These measures remove the barriers that keep people away without punishing those who stay away anyway. They also ask something of the state rather than of the citizen, which is where the duty belongs. A democracy that has done everything it can to make voting easy, and still finds people choosing not to vote, should ask what it has done to lose them.

The right to vote is the right of a free citizen to take part in self-government. It loses something essential when the state makes it mandatory. We should make voting as easy as we can, and then leave the choice where it belongs.
