Table 1 (below) shows the percentage change in the number of entries on the UK parliamentary registers in each nation of Great Britain between 2022 and 2023.

In all English regions and Wales, the number of local government register entries increased slightly between 2022 and 2023 (see Table 2). The East of England saw the largest increase (0.9%). The number of local government entries in Scotland has fallen very slightly compared to the 2022 figure (-0.1%), however it remains level with the number of 2021 entries.

Variations in levels of registration can be driven by changes in the size of the eligible population or by policy changes, such as extensions to the franchise. Changes can also be driven by reforms to the canvassing approaches used by EROs, as well as national and local voter registration campaigns. Our analysis below explores what the available data tells us about the effectiveness of the canvass.

Attainers (cont)

The reformed annual canvass may have exacerbated the decline in attainers seen from 2014 onwards, as the need to add an attainer to the register will not be identified through the data matching process. For example, many will have potential attainers but now receive fewer communications from EROs to encourage them to become registered. The different pattern in Scotland and Wales is likely to be connected to the extension of the devolved elections’ franchise to 16 and 17 year olds (and associated increased registration activity). This seems to be offsetting a systematic problem with the registration of attainers evident in England.  

Our latest accuracy and completeness study found that completeness remains lowest for attainers out of all of the age groups, and is continuing to decline. In Great Britain completeness for 16–17-year-olds has dropped from 45% in 2015, to 25% in 2018, to 16% in 2022.

Our engagement with EROs indicates that they recognise that their attainer numbers are falling, despite continued efforts to engage widely with education institutions and use education data to support this work. However, overall, a lack of staff capacity to support this work and issues with the accuracy of education data were common reasons given for not being able to do more in this area.

Despite the small increase in 2023, attainer registration is unlikely to significantly increase through the existing registration and canvass processes alone. This is an area where an assisted registration process could be beneficial. For example, data from the education sector could help EROs identify and target attainers and other young people. HM Revenue and Customs (HMRC) data could also potentially be used by EROs to assist young people to register to vote when they are allocated their National Insurance number ahead of their 16th birthday. HMRC does not hold all the data needed to register attainers, for example it does not hold nationality data. Nonetheless, HMRC data could be transferred to EROs who would then send invitations to register to attainers asking for the missing information needed to complete registration applications.  A detailed explanation of how National Insurance data could improve the registration of attainers can be found in our accuracy and completeness report.
