Vienna’s electorate gap — district by district

One quarter of the population at voting age is excluded from the 2015 Vienna elections. The growth of the city’s electorate cannot keep up with its population growth. Between 2002 and 2015, the total population has increased by 14.4%, while the electorate has gained only 4.5%. As a consequence, Vienna’s electorate gap – i.e. the share and the number of people at voting age not eligible for voting – has widened. At least half of the electorate’s increases since 2002 can be attributed to the lowering of the voting age in 2007 from 18 years to 16 years.

Ramon Bauer and Tina Frank developed the concept and design of a series of data visualisation mapping Vienna’s electorate gap in the years between 2002–2015.

During the elections on Sunday October 11, we also used the vienna map to show the winners and runners-up of the elections in a quick overview. What is especially interesting is the comparison of city council elections and district councils elections. Ramon Bauer ( wrote an article about this phenomenon.
