Turnout estimates
As we have noted before, estimating turnout is one of the hardest challenges when relying solely on survey data.
Despite the changes we have introduced to our methodology since 2015, which we believe have made our samples
more representative, polls may still be more likely to interview politically engaged people than those who are
disengaged, people may over-estimate their likelihood of voting, and they may think they are registered when in fact
they are not. For post-election analysis we have the advantage of knowing how many people turned out in the end,
but we still have to identify them in our data on the basis of the answers they gave before the election. This means that
the turnout estimates given here should be treated with particular caution, including taking into account the voter
validation results from the British Election Study when these are published (in previous elections these have shown a
similar pattern to our estimates).
The turnout figures in these charts express turnout as a % of all resident adults, which is what our sample is based on.
This gives a figure lower than the “official turnout” figures usually used, which is a % of the number of names on the
electoral register (as not everyone in Britain is registered, and some people may be registered twice even though they
can only vote once). The two measures should not be confused. We have also provided a figure for all those registered
in the full analysis on our website, however for the reasons expressed here we believe the figures based on all adults are
both more reliable and more meaningful.
