The next electoral canvass in Northern Ireland must be completed before 2023, ten years after the 2013 canvass.
To stay on the electoral register, everyone should reply to the communications that will be sent out by the Electoral Office for Northern Ireland over summer and autumn 2021. There will be a number of pieces of communication, such as informing when the canvass is happening, requesting people to respond to the canvass online or using a paper form, and reminding people previously on the register that they have not reregistered. The Electoral Commission will also be running a public information campaign to highlight the importance of completing the canvass. EONI may send out pre-populated forms using census data to some categories of voters less likely to register online. [...] The 2013 canvass added 47,196 voters (including 9,945 young people who had turned 18) to the register whom EONI had no previous record of being registered to vote in Northern Ireland. After that canvass, 112,013 voters were rolled over and retained on the register using data-matching techniques for a further three (extended from two) years. [...] The Northern Ireland Assembly Parties Panel was briefed about the upcoming 2021 canvass at its 6 October 2020 meeting.
