Electoral roll

An electoral roll (variously called an electoral register, voters roll, voters list, poll book or other description) is a compilation that lists persons who are entitled to vote for particular elections in a particular jurisdiction. The list is usually broken down by electoral districts, and is primarily prepared to assist election officials at polling places. Most jurisdictions maintain permanent electoral rolls, which are updated continuously or periodically (such as France which updates them annually), while some jurisdictions compile new electoral rolls before each election. Electoral rolls are the result of a process of voter registration. In most jurisdictions, voter registration (and being listed on an electoral roll) is a prerequisite for voting at an election. Some jurisdictions do not require voter registration, and do not use electoral rolls, such as the state of North Dakota in the United States. In those jurisdictions a voter must provide identification and proof of entitlement to vote before being permitted to vote. Electoral rolls and voter registration serve a number of functions, especially to streamline voting on election day. Voter registration can be used to detect electoral fraud by enabling authorities to verify an applicant's identity and entitlement to a vote, and to ensure a person doesn't vote multiple times. In jurisdictions where voting is compulsory, the electoral roll is used to indicate who has failed to vote. In some jurisdictions, people to be selected for jury or other civil duties are chosen from an electoral roll. Most jurisdictions close updating of electoral rolls some period, commonly 14 or 28 days, before an election, but some jurisdictions may allow registration at the same time as attending a polling station to vote; Australia closes its rolls seven days after an election is called, rather than with reference to the election day. Traditionally, electoral rolls were maintained in paper form, either as loose-leaf folders or in printed pages, but nowadays electronic electoral rolls are increasingly being adopted. Similarly, the number of countries adopting biometric voter registration has steadily increased. As of 2016, half of the countries in Africa and Latin America use biometric technology for their electoral rolls.
