Mapping the EU Referendum Results

Maps of the results of the United Kingdom’s referendum on remaining in the European Union show several different ways of presenting the results.

The BBC’s election night map is bare-bones, showing which side won which local authority, but not by how much. Appropriate for the moment, and for finding your locality, but not necessarily very revealing.

The New York Times

The New York Times’s map, another example of the fine work done by their graphics department, is a choropleth map that indicates the margin of victory in each local authority. It shows the intensity of the win by each side. (The Times does something similar with a hexagon grid map.)

The Guardian

But the EU referendum isn’t like a general election, where each electoral district has roughly the same population, and counts the the same in parliament. In this case it’s the raw vote numbers that count, and local districts can vary in size by as much as a couple of orders of magnitude. So the Guardian’s approach (at right), a hexagon grid that combines a choropleth map with a cartogram to show both the margin of victory and the size of the electorate, is probably most fit for purpose in this case.

I’m actively looking for other maps of the EU referendum results. Send me links, and I’ll update this post below.
