Bundestagswahl 2021: Map Views of the German Federal Election

Featured

Germans went to the polls to elect a new parliament and along with it a new government and a new chancellor. Since outgoing chancellor Angela Merkel did not stand for re-election after 16 years in office, this election marked a turning point in German politics. Without her standing as ‘Spitzenkandidat’, the election campaign turned into a heated fight for voter support with three parties having led the polls at times in the run-up to the election (CDU/CSU, SPD and the Greens). The final result saw the Social Democrats (SPD) winning the race after having trailed in the polls for a long time. They started catching up a few weeks ahead of the election and ended up securing 25.7 percent of the votes in the list vote (Zweitstimme) that determines the proportional distribution of seats (5.2% more than in 2017, resulting in 206 seats of the 735 seat strong parliament).
Having lost 7.9 percent points, CDU came second with 18.9 percent of the list vote (151 seats). The Green party (Grüne) came third with their best-ever result in a federal election, winning 14.8 percent of the list vote (up 5.8%, 118 seats), yet far lower than the mid-20s they polled in earlier in the year. FDP remained at a stable 11.5 percent (up 0.7%, 92 seats). The extreme right ‘Alternative for Germany‘ (Alternative für Deutschland, AfD) re-entered federal parliament (Bundestag) but with a smaller vote share of 10.3% (down 2.3%, 83 seats). CSU, the Bavarian sister-party of CDU won 5.2 percent (down 1%, 45 seats) Die Linke went down to 4.9% of the list votes but remains in parliament through the number of directly elected seats from the constituency vote (39 seats). Danish minority party SSW reached 0.1 percent in the list vote but gained one seat through special rules for parties representing minorities. Other parties not represented in parliament accounted for 7.2 percent of the valid votes.
Coalition talks are ongoing so that it is not clear yet, which parties are going to form the next government and who will become the 9th Federal Chancellor since 1949. This gives time to ponder over all the political changes that happened across the country – what better way to do so than through a series of maps, such as the 18 maps shown in this blog that dissect over 22,000 data points in cartographic form. Let’s start with an overview: The following pair of maps shows on the left the winning parties of the constituency vote (Erststimme) which directly elects a constituency into parliament and on the right the strongest party in the list vote (Zweitstimme) which determines the proportional representation for each party in the new parliament. These results are shown in large as gridded population cartograms which are proportional to the respective population there, accompanied by a small ‘conventional’ land area map:

This cartogram shows the distribution of votes for the two main candidates in the 2020 US Presidential election. Shown in diverging colours is each respective candidate who received the largest share of votes in each county. The cartogram itself shows an equal-population projection (gridded population cartogram) where each grid cell in the map is resized according to the total number of people living there. The main cartogram is accompanied by a ‘conventional’ reference map that also shows the states of Alaska and Hawaii (using state-level results for these two states):

Germany's Vote / Deutschland hat gewählt
The following cartogram series provides a detailed look into the changed political landscapes in Germany following this year’s general election. While the previous maps gave an insight into the strongest party in each constituency, these maps give a clearer picture of the vote share distribution that also determines the constitution of parliament which follows a system of proportional representation.

Bundestagswahl 2017: Electoral cartograms of Germany

The re-election of Angela Merkel as chancellor of Germany in yesterday’s federal election (Bundestagswahl) came as little surprise. Yet the final result was still widely seen as a political earthquake. The extreme right ‘Alternative for Germany‘ (Alternative für Deutschland, AfD) entered the federal parliament (Bundestag) with 12.6% of the second vote (Zweitstimme) that determines the proportional distribution of seats (having gained 7.9% compared to the 2013 election). With 94 seats, the party has become the third largest after CDU (26.8%, 200 seats, having lost 7.4%) and SPD (20.5%, 153 seats, having lost 5.2%). FDP re-entered parliament with 10.7% of the second vote (up by 6.0%, 80 seats). Former opposition leader Die Linke went up by 0.6% to 9.2% (69 seats), followed by Grüne at 8.9% (67 seats, having gained 0.5%). CDU’s sister party in Bavaria, CSU, lost 1.2% and is at 6.2% (46 seats).
AfD’s rise is the most significant change in the political landscape which also becomes visible on the new electoral maps of this year’s election. The following two maps show the distribution of the largest party in the first and second vote. In the southern parts of east Germany (Saxony) AfD managed to win three constituencies with the first-past-the-post first vote, and also became the largest party in eight constituencies in the second vote that decides on each party’s proportional representation in parliament.
Apart from this change, the electoral landscape of the strongest party in each constituency remains similar to previous elections: SPD, despite their losses, remains strongest in the urban areas of north-, central- and western Germany and are stronger in the constituency vote, while CDU dominates rural regions and much of Southern Germany except for Bavaria where CSU is taking CDU’s role. Die Linke only becomes visible as a winner in East Germany, while the Green Party holds on to its only constituency seat in Berlin:

In Focus: Brexit and the UK General Election

Political InsightThe introductory words by Prime Minister Theresa May in the Conservative manifesto 2017 outlined the main focus for the government’s General Election campaign: ‘Brexit will define us: our place in the world, our economic security and our future prosperity’. But when it came to Brexit, the campaign itself featured little of political substance from either of the two main parties. The impact of the EU-debate on the (quite unexpected) election outcome is very complex, with the anticipated Conservative gains in Leave-voting Labour seats failing to materialise.
In a contribution for the “In Focus” feature of Political Insight (September 2017, Volume 8, Issue 2) I looked at the outcome of the general election from the perspective of Brexit:

Political Landscapes of the United Kingdom in 2017

How much has the United Kingdom changed following the second general election within two years, and following the referendums on independence in Scotland in 2014 and the membership of the European Union in 2016? Each poll appeared to have had a significant impact on the political debate and the next vote which never seemed far away. As such, the 2017 general election looks like the culmination of the preceding ballots where all of the previous debates got a more or less prominent mention during the electoral campaign. Ultimately this led to some significant changes in the political landscapes of the country with each corner of the United Kingdom being affected by these dynamics.
Politicians, spin doctors and commentators quickly aim to interpret the outcome according to their views. In contrast, the following series of maps showing some key statistics and data from the election results aims to provide a more neutral as well as more comprehensive look at the underlying geographies. It shows different angles on key characteristics such as winners and runners-up in each constituency, changes in votes, vote shares of the two largest parties, turnout and changes in turnout between the last two general elections.
In this feature, different cartographic techniques are used to show how the electoral landscape in the UK is shaped not only by physical space, but also by political dimensions as well as from the perspective of people. The conventional (land area) map is therefore complemented by a hexagon cartogram where each parliamentary constituency is represented by a hexagon (some changes in constituencies over the past decades are reflected in split and merged hexagons), and by a gridded population cartogram where each area is resized according to the number of people living in that area.
Each of the three maps therefore provides a unique insight into the diverse spatial patterns of politics that emerged from the 2017 general election. To fully understand the new political landscapes of the United Kingdom, only a combination of different perspectives as shown here can help to gain a more complete picture. Geography matters not only in its physical dimension, but just as much in its social and political spaces that are depicted in these maps.
Here is the ultimate cartographic wrap-up of the 2017 general election in 21 maps:
