Fair Boundaries

Fair constituency boundaries are crucial to ensure our communities are fairly represented in Parliament.

Balancing equal constituency sizes with the need for boundaries to reflect where people actually live is a challenge. After all, we don’t all live in neat towns of 74,769 electors.

Yet under the new boundaries, the Boundary Commissions will have to work to a tight quota that could mean some odd-shaped constituencies. All constituencies will need to be within 5% of a quota based on registered electors. The exceptions are Orkney and Shetland, Na h-Eileanan an Iar, Two seats covering the Isle of Wight, and Ynys Môn. Boundaries that cut across several councils and geographical borders – including rivers and hills  – don’t make sense for local people, and make it harder for politicians to do their job.

Why are boundaries so important?

With only one winner per seat, where boundaries are drawn can have a big impact on who gets elected. See how the town council changes composition as the boundaries rotate around this example town. Animation based on the work of Geoff Powell and the PRSA

What are the issues?

Missing voters

Boundaries are based on the electoral register, meaning that areas with lower registration rates will have less Parliamentary representation.

This is a real problem given that those less likely to be on the register are typically younger, from lower-income groups, renters, and people of colour.

To ensure all citizens are counted, we recommend basing constituencies on population figures, not the electoral roll. Until we move towards automatic voter registration in the UK – which is vital – we will simply end up with rows over ‘out of date’ electoral registers forming the basis of our Parliamentary representation. MPs have to represent everyone in the area – not just registered voters.

In 2019, it was estimated by the Electoral Commission that 9.4m people were missing from the electoral roll – hardly a fair basis for redrawing the parliamentary map.

Constituency size

At the moment, constituencies vary in size from fewer than 22,000 people to more than 110,000. Whilst it’s important that constituencies are similar in size, a too-rigid system means constant boundary reviews and could mean regular changes to what seat you are in. Numbers are important, but it is also crucial to have a system that does not awkwardly split up towns or graft together different counties.

What we propose:

  • We support the principle of equalising boundary sizes, but there should be more flexibility to help seats reflect actual communities. Allowing up to 10% difference in size between seats would help to minimise disruption for both citizens and elected representatives.
  • Boundary reviews should be based on a more accurate and complete data source than the electoral register, to ensure all citizens are counted. We recommend using census population statistics, complemented by citizenship information provided by passport data.
  • There should be tough safeguards on how Boundary Commissioners are appointed, to prevent future political interference.
