Compulsory voting
Compulsory voting is increasingly resented by citizens in some countries such as Brazil, the largest country where compulsory voting is enforced: at the last presidential election in 2014, some 30 million voters, about 21% of registered voters, did not vote, despite the fact that Brazil has some of the most severe penalties enforced against non voters.
Plurality voting
Plurality voting is used for local and/or national elections in 43 of the 193 countries that are members of the United Nations. Plurality voting is particularly prevalent in the United Kingdom and former British colonies, including the United States, Canada and India.
