Our model combines data provided by YouGov with all publicly released national and constituency polls, historical election results, and data from the UK Census. Daily updates to the website are posted by Jack Blumenau, London School of Economics, most recently on 04 April 2015.

When reading our seat predictions, please keep in mind that our model may not know as much about your specific seat of interest as you do. The model knows how the general patterns of support across the UK have changed in constituencies with different kinds of political, geographic and demographic characteristics. The model uses the Ashcroft constituency polls where available, plus smaller samples of polling data for every constituency, extracted from pooling many national-level polls. However, the model does not know whether your MP is beloved by constituents or embroiled in scandal, nor does it know whether Boris Johnson or Nigel Farage is standing in your constituency, let alone what the implications of that might be. Some of this might be picked up in the polls, but not all of it will be, and we do not have much polling data to go on when it comes to constituencies. In the aggregate, these aspects of constituency-specific competition tend to average out across parties, but they certainly matter in individual constituencies. Think of our seat-level projections as a baseline for what you might expect from past election results, geography and demography, plus a little bit of polling data.
