User-defined Regional Poll

This page lets you make a prediction for the whole country that not only uses the national support figures, but also allows for regional variation.

Firstly, enter the national support figures in the first line of the table below to set the overall national swing. Our current national support figures are shown, but you can override them. As you enter national support figures, the national trend values to the right will update.

Then, area-by-area, please enter the support for each party in each area. (Area definitions) This allows different areas to have different swings from the national trend. For reference, the national trend figures on the right give a helpful indication of the expected regional support if there were no differences in swing between areas. As a starting point, you can use the uniform national trend figures (press "Use Trend Values").

Notes and Guidance

You should try to ensure that the average of the regional support figures is approximately equal to the national support. The algorithm will correct for any difference, but a large gap may cause accuracy problems.

You can display just the seats predicted to change hands ("All GB changed seats"), or see a majority-sorted list of all GB seats ("All GB seats majority-sorted"), or study any area in detail. If a area is selected, the 'Individual seat' menu list allows you to see all the area's seats majority-sorted, or to examine a particular single constituency.

Opportunities in which this page can be used:

  1. You may have your own intuition or data implying differences in swing between areas. In this case, enter the national support figures from recent polling, and the "National Trend" entries will update. Then apply your swing differences to those trends to infer regional support levels. For instance, if you think that the Conservatives will have 5% less gain in the North East than nationally, just subtract 5% from the "National Trend" figure for Con in "North East" to get their regional support there.
  2. Incorporating a Scotland or Wales poll with national polls. Just press the "Use Trend Values" button to set the support in the English areas, then enter the results of the Scottish and/or Welsh poll as the region support levels there. Then press "Predict Election".
  3. Using a large-scale poll which provides regional breakdown. The results of such a poll can be entered directly into the cells above.

Predictions can be made on the basis of the existing 2017 constituency boundaries (650 seats), the proposed new 2018 boundaries (600 seats), or any historic election since 1955.
