A continuous register or list is a list of all currently eligible voters, adjusted to take account of voter registration changes between electoral events. The continuous list is maintained by electoral administrators – unlike the civil registry, or register of citizens, maintained by other government authorities. The continuous list avoids the spike in activity involved in developing a periodic list; instead of being concentrated in the period immediately before an election, the work of developing the voters list is distributed throughout the electoral cycle. The continuous list also takes advantage of computers’ ability to store, maintain and distribute data; it records information from previous electoral events on computer for use in present and future voter registration exercises. To update the information it contains, the continuous list also draws on data gathered by other civil agencies, such as motor vehicle and driver’s registration bureaus, tax departments, and housing authorities.

Update Methods

Regular updates to the list add the names of people who have reached voting age, become citizens or otherwise become newly eligible to vote (e.g. through release from prison), or who have moved from one electoral district to another. Updates remove the names of people who were on the list but have died or ceased to meet eligibility requirements. Some election authorities update the list annually. The disadvantage of this approach is that the list is already several months out of date when it is finalized and it becomes increasingly outdated over the following year. Given the very high mobility rates in many societies, up to 20 percent of voters could well change addresses within a year. The result would be a voters list with significant problems of currency.

Another approach is to update voter information far more frequently. In some instances the election authority updates the list daily as it receives information through channels such as electronic registration or notification directly from the voter. Updating may also take place monthly as the election authority receives information from agencies with which it has data-sharing arrangements.

Data-Sharing Agreements

A continuous list necessitates data-sharing agreements between the election authority and other government bodies to which citizens report changes in their personal information that might affect their voter eligibility. For example, voters lists usually include information on each voter’s residential address. In countries in which elections are organized on the basis of separate constituencies or electoral districts, a voter is eligible to cast a ballot only in the district where he or she has permanent residence. This is why the election authority needs change-of-address information to maintain the continuous list. Someone who moved has probably reported the information to a civic agency – the driver’s licence bureau to update a licence, the tax department when completing a return or the post office to redirect mail. Election authorities maintaining a continuous list seek access to the information provided by voters to other civic agencies. They then use that information to update voter registration information.

This involves a number of challenges, including the following:

• In a country that does not assign to each citizen a unique identification number, it may be difficult to firmly identify an individual from the information provided to another agency. For example, more than one person of the same name (often parent and child) may live in the same residence. When one of them changes addresses, it may be unclear who has moved.
• If the election authority depends on information from other agencies, it needs to receive the information in a readily usable format. Different authorities, however, may have different types of computerized databases, and may not be prepared to change their systems. The election authority must find a way to work with them all. To do that demands a higher level of technical support and competence.

Internal and External Benefits of the Continuous Register

With the work of developing a voters list spread across the entire electoral cycle, the election authority can foster training and expertise among its staff. The proportion of employees in professional and ongoing positions will be higher than it would if a periodic list was used. This opens the opportunity to build enhanced voter education into the voter registration process.

For example, some countries that use a continuous list anticipate the need to register people newly eligible to vote by developing a provisional register of voters. If the voting age is 18, young people may be placed on the provisional list at age 16 or 17, and transferred to the general list on their 18th birthday. Registration thus takes place at a younger age, and the election authority can work with the high school system to develop a voter education program focusing on voter registration.
