We set out to tell a story about each one of Basel's 21 districts, using data from Basel's Office for Statistics. The data visualisations we built led us to insights about immigration, financial inequality, and a number of other social issues. Our microsite has since found a place in Basel's open data community, allowing residents to get to know their own city a little bit better.
We used handcrafted data visualisations to allow users to see a bird's eye view of the district they live in. Each district is given a ranking in terms of net income, welfare, workers, and other metrics. This allows residents to learn more about the place they live in, seeing how their district stacks up against the others.
In order to show income inequality in context, we used Gini coefficients to compare districts not only to each other, but also to global averages. This allows users to see how Basel's districts rank globally in terms of financial inequality. We were surprised to find stunningly high net worth inequality in many of Basel's districts.
During the course of our explorations of the data, we discovered clear correlations, which can be seen on the microsite itself.
Districts such as Klybeck, Rosental and Kleinhüningen have the lowest average net worth and income, but also the highest percentage of foreigners, forming a rich multi-cultural melting pot.
Conversely, districts such as Bettingen, Bruderholz and Riehen are home to a very small amount of foreigners, rather being a focal point for Basel's highest net worth residents.
Since it was crucial to us to create an engaging experience, our interactive data visualisations were given top priority. We strove to create data visualisations that encouraged users to explore and play with the data.
We're thrilled to have received plenty of positive feedback, both from Basel residents who learned something new about their city, and from Basel's open data community. We look forward to sharing more of our data visualisation work in this field in the near future.
