Datasets for the project will be published as follows:

  • The first release of the 2015 General Election dataset is now available. Please email for details on how to access the data.
  • The retrospective dataset (1945-2010) will be published over the course of 2016, beginning with the 2010 General Election in February 2016. We will provide separate election-year datasets for each general election from 1945 as well as an aggregated, time-series dataset.
