British Election Study 2019 Data Release – Internet Panel, Results File, and Expert Survey

The British Election Study Team

The British Election Study is pleased to announce the first release of BES 2019 election data.

This major release of new data consists of three new waves of our internet panel, an updated results and contextual data file, and data from an expert survey of party positions.

The 2019 BES face-to-face survey is currently in the field, and we expect to release the data from this survey in the second half of 2020.


2019 Election BES Internet Panel waves

In the run-up to the 2019 General Election we fielded two waves of our Internet Panel survey:

The pre-election wave (wave 17) was fielded between the 1st and 12th of November, and consists of 34,366 respondents.

The campaign wave (wave 18) was fielded between the 13th of November and the 11th of December as a rolling daily survey in which a random subsample of respondents are invited to take the survey on each of the 28 days of the survey. In total 37,825 respondents took wave 18, with an average of 1,351 respondents taking the survey on each day. 25,425 respondents also took wave 17, an overall wave on wave retention rate of 74%.

Immediately following the election, we fielded a post-election survey (wave 19), which was conducted between the 13th and 23rd of December. 32,177 respondents took this wave. 26,227 of these also took wave 18, an overall wave on wave retention rate of 69.3%.

19,000 respondents took all three of the 2019 election waves of the internet panel, 55% of those who took wave 17.

All waves of the BES Internet Panel are conducted by YouGov.

2019 BES Results file

Alongside the new waves of the panel data we are also releasing our 2019 General Election results file. Because the boundaries are unchanged since the 2017 election ((and 2010 and 2015 elections), the 2017 results file is an update of our previous results file, adding in the 2019 election results and candidate information to the existing data.

In addition, to aid longitudinal comparison we have also included the 2005 notional (due to boundary changes) election results that were calculated by Colin Rallings and Michael Thrasher before the 2010 election.

The Stata and SPSS versions of the results file, and the accompanying documentation, can be downloaded here, and an excel file version can be downloaded here.


2019 BES Expert Survey

As at 2015 and 2017 elections (as well as an earlier survey in 2014), we once again conducted a survey of academic experts measuring party positions on a variety of scales.

The 2019 survey data can be downloaded here.

A combined file of the 2014, 2015, 2017, and 2019 surveys can be downloaded here.
