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.
Electoral roll
Electoral rolls, under various names, are used in, for example, the United States, United Kingdom, Australia and New Zealand, but not all jurisdictions require voter registration as a prerequisite for voting, such as in the State of North Dakota in the United States. Most jurisdictions close updating of electoral rolls some period, commonly 14 or 28 days, before an election, but some American jurisdictions allow registration at the same time as attending a polling station to vote, and Australia closes the rolls 7 days after an election is called, rather than with reference to election day.
