Introduction
Berlin finished voting. Let’s look at some of the interesting facts which have not been excessively talked about in the media. All the data displayed here, even if I talk about them without giving precise numbers, are based upon demographic data that have been published within the last two days, and not on my personal speculation. I have my opinion about politics, but will try to keep it to a minimum and focus on facts.
Sources
Sources are mostly Wahlen-Berlin.de, sueddeutsche.de, spiegel.de and tagesschau.de. A good summary of numbers can be found in this pdf.
Overview
- SPD: 28.3% (-2.5)
- CDU: 23.4% (+2.1)
- GREEN: 17.6% (+4.5)
- LEFT: 11.7% (-1.7)
- PIRATES: 8.9% (+8.9)
- FDP: 1.8% (-5.8)
- OTHERS: 8.3% (-5.4) (among them NDP with 2.1%)
- Voter participation: 60.2% (+2.2)
Interesting details
- SPD: Wowereit (the current mayor) declared himself the winner of the elections. He is not (I will not discuss this in detail here), but he will be able to govern the city for another four years, either with CDU, or with the GREEN party. One third of the SPD voters said they voted because of Wowereit. The SPD lost more than 10% of their voters among young people (18-25).
- CDU: they won votes. Most of them from FDP voters (n=30.000). Many people voted them because of their “economical expertise”, only few people (especially compared to the SPD) because of their “frontman”. CDU voters are older and more religious than other voters, and live in Berlin for quite some time. Obviously, few immigrants vote for the CDU. The correlation-coefficient between young voters (18-30) and the CDU is -0.64. (East) and -0.83 (West). The coefficient for people over 60 is 0.26 (East) and 0.83 (West).
- GREEN: they won less votes than they expected to. Compared to the other recent elections in Germany, they didn’t do remarkably well – then again, +4.5% is nothing to be ashamed of. Main topics for the voters: energy, education, environment, social justice. The correlation-coefficient between middle-aged voters (30-60) and the GREEN party is 0.72 (East) and 0.75 (West), and turns highly negative for voters above 60.
- LEFT: they do not have the majority of votes together with the SPD anymore – they will not be part of the next government. They lost the majority of voters among young people (18-25), and were mostly elected by unemployed people or workers. The correlation-coefficient between old voters (60+) and the LEFT party is 0.83 (East) and -0.85 (West) (wow, that’s interesting). Very few voters are religious. There are many more interesting numbers actually, big differences in voter profile between East and West. Check out the summary-link listed at the top of the post.
- PIRATES: surprise surprise, from zero to nearly 9%. I will comment on that in detail below.
- FDP: project 2% failed. Too bad … not. 30.000 of their 2006 voters voted CDU, 8.000 voted SPD, 16.000 didn’t vote at all. The FDP didn’t get more than 5% in any demographic group whatsoever (job, age, gender). This is the 5th out of 7 elections this year in which they failed to re-enter parliament.
- OTHERS: I didn’t realize that 2006, OTHER parties together had 13.7%. That is, for German standards, remarkably high. Usually the numbers are between 2 and 5%.
Differences between East and West Berlin
The biggest differences are
- LEFT: East 22.6% (-5.5), West 4.3%
- GREEN: East 13.5%, West 20.4%
- CDU: East 14.2%, West 29.5%
- SPD had 28.x in both East and West
Overview of districts:

The German election system is a bit complicated, to summarize: many small districts were won by the GREEN party, but on a large scale, there are 12 districts in Berlin. 11 will be governed by a CDU or SPD, and 1 by a GREEN mayor (Friedrichshain/Kreuzberg).
Pirates
Apart from the fact that the Pirate Party went up to 8.9% from zero, let’s talk about some details:
- Lowest result in Charlottenburg-Wilmersdorf (considered to be rich and conversative) with 6.9%, highest result in Friedrichhain/Kreuzberg (considered to be hip, cool, square and groovy) with 14.7%. And in case you didn’t get that, let me state this clearly: the Pirates will be in all the district governments, since they reached 5% in every single district. I would have never expected that.
- 8.9% equals 130.000 people.
- The Pirates were able to steal away voters from all parties. Most of the voters came from the GREEN party, (17.000), the SPD (14.000), and the LEFT party (13.000). The majority of their voters, however, are people who voted OTHER parties (22.000) before, or didn’t vote at all (23.000). Especially the last point is something that makes this election special: getting people to vote who didn’t vote before (most probably because they did not feel represented by any party) is a pretty good thing, I guess. This is open to discussion, obviously, and highly speculative. But it is one of the most interesting facts about this election.
- About 50% of the Pirate voters decided within the last week before the elections.
- The Pirates themselves were overwhelmed by their success, and it looks like they do not have enough “politicians” (they didn’t have a single person who was on a salary before the elections) to fill in all the positions that they hold now.
- The correlation-coefficients between both young (18-30) and middle-aged (30-60) voters and the Pirate party are both above 0.50, and only negative for people above 60. Most people expected the Pirate party only to raise votes among very young people.
