Political Analysis

Three-D Politics and the Seven Tribes

A major new piece of analysis by Electoral Calculus and pollster ComRes creates a three-dimensional landscape of British politics and identifies the seven political tribes which occupy it.

Electoral Calculus has moved beyond a simplistic one-dimensional view of politics, and even gone further than our own pioneering two-dimensional view, to create a three key dimensions of political attitudes:

Using major polling work by the British Election Study, we can give a political three-D position for each poll respondent identifying their political position on each of the three dimensions.

Groups of like-minded individuals can be spotted to identify seven political tribes of people with similar political attitudes, and gain insight about their demographics and voting behaviour.

The Seven Tribes have also been reported in today's Daily Telegraph. You can see the full details of the Electoral Calculus analysis here on our website.

You can also find out your own 3D political position, and that of your neighbourhood, by taking our short 3D survey.

Regression-based prediction

Regression-based ComRes/ElCalc poll shows increased Labour lead

Working with leading pollster ComRes, Electoral Calculus has applied modern regression-based techniques to show an increased Labour lead over the Conservatives.

Regression techniques, also known as MRP, are growing in popularity in the market research industry as a way to make polling more accurate again. Classic polling techniques have had problems with accuracy in recent years as representative sampling becomes harder.

Working jointly with ComRes, we have applied the regression techniques to recent polls. Those polls showed Labour and the Conservatives about equally popular, when they were analysed with conventional polling techniques. But under the new regression techniques, they show a Labour lead of 4pc over the Conservatives.

An additional feature of regression techniques is that they give a seat-by-seat breakdown which each seat is individually predicted, rather than relying on uniform national swing assumptions.

This regression prediction by ComRes and Electoral Calculus was featured in the Daily Telegraph, "Tory Leavers most in danger of losing seats" on 20 April 2019.

Details of the regression method, and its successful testing with earlier pre-election polls can be found here.
