2. Summary

Electoral statistics are collated by the Office for National Statistics (ONS) and published for the UK and its constituent countries, local government areas and parliamentary constituencies. They provide annual counts of the number of people who are on the electoral registers, usually at 1 December each year.

References in this release to electoral statistics for 2014 should be taken to mean electors included on the registers published on 1 December 2014 in England, Wales and Northern Ireland. These are the first registers published following the introduction of Individual Electoral Registration (IER) in England and Wales in June 2014. Electoral registers in Scotland are due to be published on 2 March 2015. This is because the transition to IER in Scotland was delayed in order to begin after the Scottish Independence Referendum in September 2014.

See background note 5 for further details on comparing electoral statistics for different years.

Electoral statistics for Scotland are due to be published on 16 April 2015. Electoral statistics for the UK as a whole will be published on the same date.

3. Introduction

Electoral statistics are available for the two main groups of voters:

  • Parliamentary Electors – those entitled to vote in Westminster Parliamentary elections
  • Local Government Electors – those entitled to vote in local government and/or European elections1

The difference in who is entitled to vote at parliamentary and/or local elections largely depends on residence and citizenship conditions. Local Government Electors for example, include those European Union citizens resident in the UK who are not entitled to vote in Westminster Parliamentary elections, whilst Parliamentary Electors include British citizens resident overseas who are not entitled to vote in local government elections. Further information on the eligibility criteria can be found in a Quality and Methodology Information paper from our Quality Reports for Government Statistics page.

There are 3 key reasons why the registered numbers of electors in an area can change from year to year:

  • a change in the size of the population who are entitled to vote; for example, due to international migration
  • a change in the proportion of the eligible population who actually register to vote; for example, more people registering as a result of better canvassing
  • differences in administrative practices; for example, the extent of use of the ‘carry forward’, which allows for an elector to be retained on the electoral register for a year when they have not responded to an annual canvass

In particular the introduction of Individual Electoral Registration (IER) in 2014 has introduced new administrative practices. Although IER does not change who is eligible to vote, it may have changed the proportion of those eligible that are registered to vote. More information on IER is available in the section on Related Information.

Methods, quality and uses

For England and Wales, electoral statistics are taken from data supplied to ONS by local Electoral Registration Officers. Data for Northern Ireland are collected by the Electoral Office for Northern Ireland (EONI). ONS collated these statistics for England, Wales and Northern Ireland using the data supplied. A further release containing statistics for the UK will be published on 16 April 2015 including data for Scotland, which is collected by National Records of Scotland (NRS).

More information is available from our Electoral Statistics Information page.

Electoral statistics are gathered and published by ONS. They are used by Boundary Commissions, the Electoral Commission, and central government to help with the improvement of electoral policies and for statutory reviews of parliamentary constituency boundaries. The statistics are also of interest to Members of Parliament and the general public.

Electoral statistics represent the most accurate count possible of the number of people on electoral registers each year. They are subject to full quality assurance procedures and are reliable and provide comparable data across the UK constituent countries. Information on the quality of these statistics is provided in a Quality and Methodology Information paper available from our Quality Reports for Government Statistics page.

Notes for introduction

  1. To be entitled to vote in European elections in the UK, European Union (EU) citizens are required to request the right to vote in this country rather than their home country. Those persons who do not make this request will not be included in the European Parliament electorate.

4. Parliamentary electors

The total number of parliamentary electors in England, Wales and Northern Ireland and the percentage changes between 2013 and 2014 are:

  • England – 37,831,600, a fall of 2.0%
  • Wales – 2,225,700, a fall of 3.1%
  • Northern Ireland – 1,232,400, a rise of 1.2%

Figure 1 shows the different patterns of change in parliamentary electors between England, Wales and Northern Ireland over the last 5 years.

From 2009 to 2012 the number of electors increased in all 3 areas, although growth was highest in Northern Ireland. Small decreases (of less than 1%) were recorded in all 3 areas between 2012 and 2013. However, between 2013 and 2014 the parliamentary electorate of England fell by approximately 766,000 people (or 2.0%) and the parliamentary electorate of Wales fell by approximately 72,000 (or 3.1%); Northern Ireland saw similar growth to that which occurred between 2011 and 2012.

The fall recorded in the parliamentary electorate between 2013 and 2014 in England and Wales is likely to be due, at least in part, to the introduction of Individual Electoral Registration (IER). Northern Ireland uses a continuous registration system that was introduced in 2006.

Figure 2 shows that although all English regions showed declines in their parliamentary electorate between 2013 and 2014, there was considerable variation between them. The North East declined by 3.5% while the West Midlands declined by less than 1% and was the only area that saw a smaller decline than that recorded between 2012 and 2013. In general, northern areas of England showed larger declines than southern areas.

Parliamentary constituencies

There are at present 650 Westminster Parliamentary Constituencies in the UK made up of 533 in England, 59 in Scotland, 40 in Wales and 18 in Northern Ireland. These boundaries came into force at the May 2010 General Election. This release provides counts of the total number of parliamentary electors for the 591 parliamentary constituencies in England, Wales and Northern Ireland.

The typical size of constituencies differs between the constituent countries of the UK with a median total parliamentary electorate across constituencies of about 71,000 in England, 67,500 in Northern Ireland and 55,100 in Wales.

In 2014, the parliamentary constituency with the largest electorate was the Isle of Wight at 107,600, while the constituency with the smallest electorate was Arfon in Wales at 38,000. The Isle of Wight has an unusually large electorate due to the geographic constraints of being an island constituency.

The total parliamentary electorate grew in 114 constituencies (19%) between 2013 and 2014. In total, 50 constituencies had growth of more than 1% in their parliamentary electorate including 4 which grew by more than 3%.

As shown in table 1, all of the 10 constituencies with the greatest percentage growth in parliamentary electors between 2013 and 2014 are in England. Of these, 9 are county constituencies, areas which are partly or mostly rural. The labelling of a constituency as borough or county is made by the relevant Boundary Commission.

Note that the constituencies of Northampton South and Workington both appeared in the list of constituencies with the greatest percentage fall in parliamentary electors in the previous year. The turnaround for these constituencies may in part link to changes in population size or the population entitled to vote, or administrative differences in how the register was put together between the years.

Torfaen (ranked 99th) was the only constituency in Wales where the number of parliamentary electors increased between 2013 and 2014 – it recorded growth of 0.2%. The constituency of Foyle (ranked 14th) showed the greatest growth in Northern Ireland at 2.1%. It should also be noted that Foyle recorded the greatest fall in parliamentary electors in Northern Ireland in the previous year.

The total parliamentary electorate fell in 477 constituencies (81%) between 2013 and 2014. However, 64 constituencies had a fall of more than 5% in their parliamentary electorate including 10 which fell by more than 10%.

Table 2 shows that the 10 constituencies with the greatest percentage fall in parliamentary electors between 2013 and 2014 include 8 located in England. The majority of these are classified as borough (or mainly urban) constituencies. The remaining 2 are located in Wales, including Cardiff Central, the constituency with the greatest percentage fall in parliamentary electors at -18.3%. All these areas contain towns or cities with large student populations.

No constituencies in Northern Ireland recorded a fall in parliamentary electors between 2013 and 2014.

5. Local government electors

The total number of local government electors in England, Wales and Northern Ireland and the percentage changes between 2013 and 2014 are:

  • England – 39,185,000, a fall of 2.0%
  • Wales – 2,254,200, a fall of 3.2%
  • Northern Ireland – 1,257,000, a rise of 1.3%

Figure 3 shows the different patterns of change in local government electors between England, Wales and Northern Ireland over the last 5 years. Overall, the pattern of change is very similar to that for parliamentary electors shown in figure 1.

Over the last 5 years, the number of local government electors in England has grown by an average of just 0.1% each year, with growth during the period 2009 to 2012 offset by the falls seen between 2012 and 2014. In particular, the number of local government electors in England fell by approximately 817,000 between 2013 and 2014.

The pattern for Wales is similar to that of England, while the number of local government electors in Northern Ireland has increased every year with the exception of 2012 to 2013.

Figure 4 shows that the -2.0% change in the number of local government electors in England, between 2013 and 2014, hides considerable variation between different regions. The North East had the largest change at -3.6%, while the West Midlands had the smallest, at -0.9%. As for parliamentary electors, the West Midlands was the only area where the decrease seen between 2013 and 2014 was less than that recorded the previous year.

Local government areas

Local government areas are unitary authorities, London boroughs and district councils in England; unitary authorities in Wales; and council areas in Scotland and Northern Ireland. At December 2014 there were a total of 406 local government areas in the UK; 326 in England, 32 in Scotland, 26 in Northern Ireland and 22 in Wales. This release provides counts of the total number of local government electors for the 374 local government areas in England, Wales and Northern Ireland.

In 2014, the size of local government electorates ranged from the 1,600 electors in Isles of Scilly to 728,700 in Birmingham. The typical size of local government electorates varies between different areas of the country with a median across local government areas of about 97,500 in Wales and 97,300 in England compared to only 41,300 in Northern Ireland.

The total local government electorate grew in 85 local government areas (23%) between 2013 and 2014. This compares to 190 areas, or 51%, between 2012 and 2013. However, only 43 areas had growth of more than 1% in their electorate; while 4 areas had growth of more than 3%.

All of the local government areas with the greatest percentage growth in local government electors between 2013 and 2014 are in England, as shown in table 3. The greatest percentage growth in a local government area in Northern Ireland was Derry at 2.1% (ranked 11th), while Torfaen was the only local government area in Wales where the local government electorate grew during the period (0.1%, ranked 76th).

Wellingborough; East Devon; Tonbridge and Malling; and Allerdale were all amongst the top 10 areas with the largest percentage falls in local government electors last year. Their turnaround this year may be due to changes in population size, the population entitled to vote or administrative differences in how the registers were put together between 2013 and 2014.

The total local government electorate fell in 289 local government areas (77%) between 2013 and 2014, compared to 183 areas (49%) in the previous year. Of those, 51 areas had a fall of more than 4%, including 2 which fell by more than 10%.

The top 10 local government areas with the greatest percentage fall in local government electors are shown in table 4. There are 8 in England and 2 are in Wales, including Ceredigion which had the largest percentage fall at 12.7%. Also, many of these areas are those with large student populations. No areas in Northern Ireland recorded a fall in local government areas between 2013 and 2014.

8 .Background notes

  1. National Statistics are produced to high professional standards set out in the Code of Practice for Official Statistics. They undergo regular quality assurance reviews to ensure that they meet customer needs. They are produced free from any political interference.

  2. Electoral statistics for 2014 are available from the electoral statistics section of the ONS website.

  3. Published tables include counts of local government electors and attainers by local government areas and parliamentary electors and attainers by parliamentary constituency. An attainer is a person who attains the age of 18 during the currency of the register, and is entitled to vote at an election on or after his or her 18th birthday.

  4. A report describing the methodology used to create the electoral statistics estimates can be found on our Electoral Statistics Information page.

  5. Electoral statistics usually relate to registers published annually in December. Time series comparisons of electoral statistics in this release use figures for December each year, with the exception of 2012 and 2013 for England and Wales. The 2012 electoral statistics relate to October 2012 instead of December 2012 in England and Wales (excluding London). The 2013 electoral statistics relate to February 2014 in England and March 2014 in Wales. This means that changes between the 2012, 2013 and 2014 electoral statistics may not exactly reflect annual change, as the actual time difference between the annual sets of figures may be up to 18 months (the maximum difference is in Wales – October 2012 to March 2014).

  6. Information on previous elections held in the UK or its constituent countries and a list of upcoming elections and referendums is available from the Electoral Commission.

  7. A list of those people that have pre-release access can be found on the ONS website.

  8. This is the first release of 2014 electoral statistics. No revisions of this dataset have been made.
