Regrexit Map

27 March 2019

On 23rd June 2016 the British public voted with a majority of 51.9% to 48.1% to leave the EU. Many were shocked at the result, expressing regrexit for the outcome.

Three years later, a petition calling for the decision to be reversed has been signed by over 5.8 million people. We can use the petition data to compare the referendum results with how people feel now.


This map shows the level of regrexit for each constituency. Click on the map to see the details for each.

What does it all mean?

Each constituency is shaded between blue and yellow.

Blue (regrexit value between 0.0 and 1.0) indicates the population accepts the result in the constituency.

Yellow (regrexit value greater than 1.0) indicates the population regrets the result.

Nothing has changed

Back in May 2016 a similar petition attracted over four million signatures. At the time I used the data from that petition to generate a map like this, which you can still view here. Take a look at it too, and marvel at how little things have changed.

How is it calculated?

We compare the referendum results against the number of people who signed the petition. For each constituency we calculate the number of signatures we would expect given the remain votes cast in the area and compare it against the number of actual names on the petition. The regrexit value is then calculated as:

Regrexit = signatures / Expected.

We have to make a few assumptions, which you can find in the full details.

Are you serious?

No, not really. We actually have to make a few too many assumptions. Maybe there's a hint of truth in the numbers, but that's for you to decide.
