Voter Turnout (VT) is determined by matching the total number of votes cast during an election against the total number of eligible voters. VT levels can be indicative of public attitudes and perceptions – high turnout can reflect high levels of interest and trust, while low VT can be a sign of disinterest or negative views of elections.
In some contexts, VT may be inflated to give a show of legitimacy, either through coercion, incentives, or fraud. For this reason, countries classed as ‘not free’ are not included in this infographic.
