Abstract
Understanding how the electoral behaviour of a population changes in a country is key to understand where and why social change is happening. In this paper, we apply methods from network science to the study the middle-long-term evolution of Swedish electoral geography. Sweden is an interesting case since its political landscape has significantly changed over the last three decades with the rise of the Sweden Democrats and the Green Party and the fall of the Social Democrats. By partitioning the Swedish municipalities according to their similarity in voting profiles, we show that Sweden can be divided into three or four main politico-cultural communities. More precisely, a transition from three to four main politico-cultural communities is observed. The fourth community emerged in the early 2000s, and it is characterized by a large vote-share for the Sweden Democrats, while almost all other parties underperform.
