After every Danish election, we see which parties won which municipalities. But what about the relative changes in party support? Where are parties growing, where are the shrinking, and are there any obvious patterns to these changes? I decided to find out.

Map of Danish political shifts

First, choose a political party from the right by clicking on them. The map now shows the Changes in Percentage Population support.

If Bornholm only had 100 people in it in 2011, and 10 people voted for SF, that would be 10% of the population supporting them. If Bornholm’s population dropped to 50 in 2015, but 20 of them supported SF, this would be 40% support.  The Change in Percentage Population support would be +30%.

Hovering over Bornholm would indicate this in the upper right corner.

The colors of map indicate the strength of the change relative to other municipalities. So, if SF gained +30% in Bornholm, but lost -10% in Aarhus, we would see Bornholm as a darker shade of red than Aarhus.

Note that even if all of the numbers are negative (as was the case for some parties), the darker colors will still indicate where that party lost less than other parts of the country; in other words, the darker colors will always show where the party became stronger.
