Electoral figures

Guide to the 2011 electoral figures

How the figures are used

The Boundary Commission for England will be using the 2011 electorate figures for the next review of parliamentary constituencies (the 2013 Review). 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 2009 (the 2010 electorate figures) and for 1 December 2010 (the 2011 electorate figures)

Guide to using the spreadsheet

There are two summary worksheets:

  1. Review areas: This gives the number of parliamentary electors in each London Borough, Unitary Authority, County and District Council in England.  This also shows the Electoral Quota (EQ).  This is the calculated by dividing the total number of parliamentary electors in England by the total number of existing constituencies (533).  Also shown is the the number of parliamentary electors in a local authority divided by the EQ. Please note that the EQ shown on this spreadsheet relates to the existing constituencies and is not the EQ that will be used in the 2013 review of parliamentary constituencies. See Newsletter 2/2011 for further details on start of 2013 review.
  2. Seats: This gives the number of parliamentary electors in each of the 533 existing constituencies in England.  These are the constituencies that came into effect at the General Election held on 6 May 2010.  Also shown is by how much the electorate of each constituency diverges from the EQ and the ranking of each constituency in terms of the number of electors.

There are worksheets for each review area as created in the last review (undertaken between 2000 and 2006). These worksheets are set out in the following format:

  • Column A  a number to the corresponding ward name.
  • Column B  the name of the ward (as shown in the Statutory Instrument (SI) that created the wards.
  • Column C  the former (6 digit) ONS ward code for the corresponding ward name – this code was in use until 31 December 2010.
  • Column D  the new (9 digit) ONS ward code for the corresponding ward name – this code came into use on 1 January 2011.
  • Column E  the 2010 ward electorate figure for the corresponding ward.
  • Column F  the 2011 ward electorate figure for the corresponding ward
  • Column H  the parliamentary constituency in which the corresponding ward is situated.

Where a ward is divided between constituencies, an electorate figure for each part is shown in Columns E and F.

Underneath each District is shown the name of the Statutory Instrument that created the wards in that District. View the relevant Statutory Instruments.
