Question to the Cabinet Office:

To ask Her Majesty’s Government whether, prior to the Electoral Commission embarking on a boundary review, they plan to publish a report setting out, constituency by constituency, (1) the number of people on the Electoral Roll for the 2010 General Election; (2) the number of people on the Electoral Roll for the 2015 General Election; and (3) the number of over eighteen year-olds of United Kingdom, Irish and qualifying Commonwealth nationality in the 2011 Census.

Electoral Statistics are published annually by the Office for National Statistics and can be found at www.ons.gov.uk.

The Electoral Commission publishes data on the registers used for the UK Parliamentary elections in 2010 and 2015, which is available online.

The published ONS data based on the 2011 Census does not provide a constituency breakdown by age or nationality.

Boundary reviews are conducted by each of the four independent UK Boundary Commissions, in line with the rules set out in the Parliamentary Constituencies Act 1986, and the next boundary review is due to be completed by October 2018.
