Changing Political Landscapes of Germany 2017

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

Featured

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:

The Growth and Decline of Urban Agglomerations in Germany

Innovative maps that illustrate the most recent socio-demographic urban changes in the major city urban agglomerations in Germany have very recently been produced in a joint project of the School of Geography and the Environment at the University of Oxford and the Research Institute for Regional and Urban Development Dortmund (Germany).
The Research Institute for Regional and Urban Development (Institut für Landes und Stadtentwicklungsforschung, ILS) investigates new social processes, especially those involving urbanisation in Germany and Europe. This includes economic, social and structural processes that are compared and monitored over time to gain a better understanding of the underlying developments. Testing state-of-the-art visualisation techniques are a significant part of this effort. This was the focus of a collaboration between researchers of the University of Oxford and the ILS Dortmund which resulted in the development of a series of highly effective maps called “cartograms” that provide new insights in the changing geographies of city regions in Germany.

Refugees in Germany

As stated in a report earlier this year, “wars, conflict and persecution have forced more people than at any other time since records began to flee their homes and seek refuge and safety elsewhere” (see more details and a global map series at http://www.viewsoftheworld.net/?p=4541). In Europe, this has lead to a human crisis with many refugees seeking to get to the continent via sea and land. Beyond the human tragedy, the political debate has become ever more heated over who is willing to host the migrants.
Unlike the debate in the UK, where the government is more concerned about closing the borders into Britain at the most vulnerable entry point in France, Germany’s government is looking into ways how an expected 800,000 migrants can be accommodated this year. Using data from the most recent official statistics the following cartogram shows where refugees and asylum seekers are allocated in Germany showing the states (or Laender) rezised according to the absolute number of asylum seekers and refugees living there (the colours merely distinguish the different Laender and do not represent any further data):

Germany’s Population Growth and Decline

Some time ago I have published an analysis of the changing demographies of Germany on this website (see also the map at the end of this post). I used the data from this analysis to develop some further cartogram visualisations that put the increase and decline into the focus, showing how heterogeneous these trends are evolving spatially in Germany. The following maps show gridded cartogram transformations of population change in Germany in which each grid cell (representing an equal physical space) is resized according to the total estimated population increase (right map) or decline (left map) in the period of 1990 to 2010. They show, how population patterns chances in the first two decades after reunification:
