Electoral Calculus is a political forecasting web site that attempts to predict future United Kingdom general election results. It considers national factors and local demographics.
The site was developed by Martin Baxter, [1] who was a financial analyst specialising in mathematical modelling. [2]
The site includes maps, predictions and analysis articles. It has separate sections for elections in Scotland and Northern Ireland. [3]
From April 2019, the headline prediction covered the Brexit Party and Change UK – The Independent Group. Change UK was later removed from the headline prediction ahead of the 2019 general election as their poll scores were not statistically significant.
The site is based around the employment of scientific techniques on data about the United Kingdom's electoral geography, [1] which can be used to calculate the uniform national swing. [4] It takes account of national polls and trends but excludes local issues. [5]
The calculations were initially based on what is termed the Transition Model, which is derived from the additive uniform national swing model. This uses national swings in a proportional manner to predict local effects. [6] The Strong Transition Model was introduced in October 2007, and considers the effects of strong and weak supporters. [7] The models are explained in detail on the web site. [6]

It was listed by The Guardian in 2004 as one of the "100 most useful websites", being "the best" for predictions. [9] In 2012 it was described by PhD student Chris Prosser at the University of Oxford as "probably the leading vote/seat predictor on the internet". [10] Its detailed predictions for individual seats have been noted by Paul Evans on the localdemocracy.org.uk blog. [11] Academic Nick Anstead noted in his observations from a 2010 Personal Democracy Forum event, that Mick Fealty of Slugger O'Toole considered Electoral Calculus to be "massively improved" in comparison with the swingometer. [12]
With reference to the 2010 United Kingdom general election, it was cited by journalists Andrew Rawnsley [13] and Michael White [14] in The Guardian . John Rentoul in The Independent referred to the site after the election. [15]
The founder of Electoral Calculus, Martin Baxter, and its sole employee, Marwan Riach, have regularly appeared on UK and international media to offer polling expertise to their audience.

An electoral swing analysis shows the extent of change in voter support, typically from one election to another, expressed as a positive or negative percentage. A multi-party swing is an indicator of a change in the electorate's preference between candidates or parties, often between major parties in a two-party system. A swing can be calculated for the electorate as a whole, for a given electoral district or for a particular demographic.
Manchester Withington is a constituency represented in the House of Commons of the UK Parliament since 2015 by Jeff Smith of Labour. Of the 30 seats with the highest percentage of winning majority in 2017, the seat ranks 25th with a 55.7% margin, and is the only one of the twenty nine of these seats won by the Labour Party in which the second-placed candidate was a Liberal Democrat, rather than Conservative. This is despite being a Conservative seat right up to 1987, then becoming relatively safely Labour, then Liberal Democrat from 2005 to 2015 before they lost on a large swing in 2015, after which Smith substantially increased his majority.

The 2015 United Kingdom general election was held on Thursday 7 May 2015 to elect 650 Members of Parliament to the House of Commons. It was the only general election held under the rules of the Fixed-term Parliaments Act 2011 and was the last general election to be held before the United Kingdom would vote to end its membership of the European Union (EU). Local elections took place in most areas of England on the same day.
In the run-up to the general election on 8 June 2017, various organisations carried out opinion polling to gauge voting intentions. Results of such polls are displayed in this article. Most of the polling companies listed are members of the British Polling Council (BPC) and abide by its disclosure rules.
