In this map of the month, we take a closer look at the relation of election results and net rents. For our evaluation, we chose three cities from Baden-Württemberg, because of the recent “Landtagswahl” (state election) at the 14th of March. There are two dominant parties in this region: Grüne and CDU. The first one focuses more on ecological policy and is considered to be left-liberal in a sociopolitical way. The other one is considered to be more conservative and economic-liberal based on Christian values.

In comparison to the last state election in 2016, the Grüne won more election districts (58 of 70) and the CDU won the other 12 districts. It can be said, that CDU is predominatley voted in more rural areas whereas Grüne wins districts which include the big cities of Baden-Württemberg.

In this study, we focus on Stuttgart, Mannheim and Karlsruhe in more detail. We chose these three cities, because they have common features: These are the biggest cities in this federal state and all have universities as well as a lot of industry. In this investigation, we want to show the difference in the election results between the city districts and the correlation with the associated average net rents. At the end, we will outline and discuss the trends which are present in all three cities.

Method

The election results are provided by the sources which we listed at the end of this blog. The net rents are supplied by ImmobilienScout and are given in €/m2. For this analysis, we used the most recent information which are the rents of Oktober 2020. After gathering the information, we used the application QGIS to create separate color-coded maps of the cities for each party, which are shown below.

Results

We start with the maps of the state capital Stuttgart. In every city district, the Grüne got the most votes. However, the percentage ranges from 28.7% to 47%. The districts with the highest values are located in the center with net rents of about 15 - 16 €/m2. Towards the periphery, the rents decrease to about 12 - 14 €/m2 as well as the votes for Grüne. In contrast, the map of the CDU votes shows the exact opposite: Increasing votes with decreasing rents towards the city fringe with the percentage ranging from 16.6% to 26.7%. Similar trends can be shown for SPD and AfD (like CDU) and for die Linke (like Grüne). The results of the FDP are not as clear, but they tend to follow the trend of the CDU with the contrast of a higher vote-increase in the south than in the north.

The center of Stuttgart includes the university as well as the station and cultural sites like the castle, castle garden and theaters. The periphery is characterized by the automobile industry of Daimler in the east and Porsche in the north where also the company Bosch is located.
