Compulsory voting
, 22 countries were recorded as having compulsory voting. Of these, only 10 countries (additionally one Swiss canton and one Indian state) enforce it. Of the 30 member states of the Organisation for Economic Co-operation and Development, 10 had forms of compulsory voting.

Supporters of compulsory voting also argue that voting addresses the paradox of voting, which is that for a rational, self-interested voter, the costs of voting will normally exceed the expected benefits. The paradox disproportionately affects the socially disadvantaged, for whom the costs of voting tend to be greater. Australian academic and supporter of compulsory voting, Lisa Hill, has argued that a prisoner's dilemma situation arises under voluntary systems for marginalised citizens: it seems rational for them to abstain from voting, under the assumption that others in their situation are also doing so, in order to conserve their limited resources. However, since these are people who have a pronounced need for representation, this decision is irrational. Hill argues that the introduction of compulsory voting removes this dilemma.
