The first steps for preparing a continuous list of voters are similar to those for compiling a periodic list. The key difference between the two systems is that after the initial registration, the information gathered becomes the backbone of the continuous list, and subsequent efforts focus on verifying the accuracy of the data and regularly updating the list. The type of information collected can make it easier to maintain the list. For example, it is common to find more than one person with the same name.Unique identifiers (e.g. birth date or citizen identification number) are therefore needed to distinguish each voter.
In contrast, the periodic list is developed for one specific electoral event. It sometimes uses information from past lists but there is no standing list of voters in a system with a periodic list, as there is in a system with a continuous list.
Reduced or Increased Number of Registration Centres
After the initial registration drive to establish a continuous list, the election management authority may dismantle most registration sites but keep open a small number for people needing to register or update their registration information. Despite the limited numbers, registration centres often represent a significant cost component of a continuous list system. The cost can be reduced with new electronic list maintenance methods that draw on a variety of data sources – an approach resembling that of data collection for a civil registry.
Normally there is one registration centre for each electoral district or county. When an election is called, the election management authority may increase the number of centres or set up mobile units to visit areas where registration rates have been low in the past. The election management authority should develop valid performance measures (based on currency, accuracy and completeness) and systematically attempt to improve performance.
Timely Updating a Must
A continuous voters list may become out of date. Performance measures – for example, of list currency – can help identify shortcomings and indicate how to achieve improvements.
For example in Britain, the deadline for submitting voter information changes is in the Fall (Autumn), and the preliminary voters list is published at the end of November each year. A time is then allowed for presenting claims and objections and the final voters list is published approximately 4 months later on February 15. This list remains in effect from February 16 until February 15 of the following year, or 16 months after the deadline for submitting information changes. Voters who have moved to another electoral district in the interim cannot vote in their new district – a classic case of administrative loss of right to vote. The jurisdiction has introduced changes to allow more frequent updating of the voters list.
Although this jurisdiction is officially described as using a continuous list, in fact it takes a yearly snapshot of the electorate and defines voters’ eligibility on the basis of information collected at the time of the snapshot rather than continuously throughout the year. This example is something of a hybrid between a periodic and a continuous list. Other jurisdictions with a continuous list update it far more often. They may conduct monthly data-sharing activities with other public bodies or make daily updates to integrate information supplied directly by voters.
Across the United States, the deadline for registration is 30 days before an election, and most jurisdictions require certified voters lists to be produced no later than two weeks before the election.
