General description
This dataset shows the number of people who were registered on the electoral roll on the date shown to vote at a National Assembly for Wales election, and the number of attainers (a person who attains the age of 18 during the currency of the register, and is entitled to vote at a National Assembly for Wales election on or after his or her eighteenth birthday).

To make sure that the electoral register was as complete and accurate as possible ahead of the introduction of Individual Electoral Registration (IER) in summer 2014, the annual publication of electoral registers in Great Britain, normally due on 1 December 2013, was delayed until spring 2014. Electoral registers were published on 10 March 2014 in Wales.

The data are based on the National Assembly for Wales constituency boundaries which came into effect at the elections on 3 May 2007 with subsequent changes as a result of local government boundary changes in 7 areas under the Parliamentary Constituencies and Assembly Regions (Wales) (Amendment) Order 2011. The Order did not make the same changes to the boundaries of the Westminster parliamentary constituencies and came into effect on 14 December 2011 so from this point onwards there are some differences between the Westminster parliamentary constituencies and the National Assembly for Wales constituencies. This also means that for some constituencies, the data for 2012 onwards is not consistent with data for previous years. These areas are marked in the data.

Note that entitlement to vote is different for National Assembly for Wales and Westminster parliamentary elections. EU citizens resident in Wales are entitled to vote at National Assembly for Wales (and local government elections) but not at Westminster Parliamentary elections.

Data collection and calculation
Data are collected by local authorities as part of an annual voter canvas. The results are then collated and published by constituency area by the Office for National Statistics.

Frequency of publication
Annual

Data reference periods
Data are produced and reported annually and relate to the 1 December each year.

In 2012, the annual voter canvass was conducted early and the publication of the electoral roll brought forward to 16 October to allow for the Police and Crime Commissioners (PCC) elections for England and Wales held in November 2012.

To make sure that the electoral register was as complete and accurate as possible ahead of the introduction of Individual Electoral Registration (IER) in summer 2014, the annual publication of electoral registers in Great Britain, normally due on 1 December 2013, was delayed until spring 2014. Electoral registers were published on 10 March 2014 in Wales.

Users, uses and context
The data are used to estimate the electoral size of each of the National Assembly for Wales constituencies and to support any research that may be conducted ahead of relevant elections.

The principal users of these data will be the Members’ Research Service of the National Assembly for Wales (in supporting all constituency and regional Assembly Members or AMs); individual AMs and their researchers; Welsh Ministers and their private office staff; the media; press and policy officials in the Welsh Assembly Government; students, academics and universities; and citizens, private companies, and other interested individuals.

Rounding applied
No rounding is applied to the data.

Revisions information
No revisions have been applied to the data.
