Electoral data

How the figures are used

The Boundary Commission for England is using the 2011 electorate figures for the 2013 Review of Parliamentary constituency boundaries. The Parliamentary Voting System and Constituencies Act 2011 has amended the Parliamentary Constituencies Act 1986 and makes this a requirement.

Figures covered

Each district council in England supplies the Population Estimates Unit of the Office for National Statistics (ONS) with a statistical return each year showing the number of electors on the electoral register that is published each year on 1 December. The spreadsheet has the number of Parliamentary electors in each ward in each district in England for 1 December 2010 (the 2011 electorate figures).

Guide to using the spreadsheets

You can find the spreadsheets for each region on the regional pages. For each region, the spreadsheets are arranged as follows:

  • an initial tab with our proposed constituencies, their electorate, the amount the electorate varies from the electoral quota, that variance as a percentage, and the size in square kilometres of the proposed constituency
  • a number of further tabs, one for each sub-region within the region. These tabs contain our proposed constituencies, with the area of each district they contain; and then a list of wards in each district and their proposed constituency. The wards also have their ONS codes, for easy identification (see below). Underneath each district is shown the name of the Statutory Instrument that created the wards in that district. To view the relevant Statutory Instruments, please go to www.legislation.gov.uk/uksi.
