Further reform of the annual canvass and electoral registration

An effective canvass process is an important tool to provide for high-quality registers at all times and to minimise the need for significant updates ahead of major polls. However, evidence from our analysis of canvass data in recent years continues to suggest that the reformed canvass process is still not fully picking up ongoing population movement.

This means that EROs will continue to face the challenge of processing large numbers of registration applications in the period immediately before major electoral events, from new electors or from people who have changed address and were not picked up by the canvass. This continues to increase risks to the resilience of electoral administration teams in the pre-election period, when they are under significant resource pressures and have critical election deadlines to meet.

 

Our analysis of the 2023 annual canvass data also shows that many households continue not to respond to the canvass, including where the data matching step has indicated that changes may be needed. Further research is needed on the effectiveness of different approaches to canvassing properties, including the design and messaging of canvass communications, to establish whether changes could be made that would likely improve response rates.

We will carry out further analysis of this data to better understand what factors may have the most significant impact on responses to canvass communications, particularly for those properties where data matching suggests that changes might need to be made. We will identify areas that appear to be outliers in terms of response rates, and use that information to prioritise our engagement with EROs and their teams ahead of the 2024 canvass. This will help us to identity further evidence about the impact of different approaches to contacting properties during the canvass. We will also consider whether changes may be needed to improve the design and usability of canvass communications, to help improve response rates.
