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.
Election
The question of who may vote is a central issue in elections. The electorate does not generally include the entire population; for example, many countries prohibit those who are under the age of majority from voting, all jurisdictions require a minimum age for voting.
