My income

Description

Denmark has a very, very small gap between rich and poor. But is this a good thing or not? That was a topic at the Danish Broadcasting Corporation the winter 2016. While TV and radio covered the subject with news, debates, and documentaries, the Investigative Data Team decided to use income-data to interact with the readers. We wanted to let them see the national variation in income and test their assumption about where in the distribution their personal income is.
We acquired data from Statistics Denmark and developed an interactive component. What was unique for this small project was our solution for visualization. We made a small gamification aspect where people first had to guess how many Danes earn less than you before being shown their own result. We saved their answers and we were surprised by the result: More than 125.000 Danes checked out their income compared to the national variation – and most of them guessed that they were in a lower percentile, than they actually were.

Origin

The interactive component was developed over several iterations focusing on mobile-first development. In each iteration we got a more focused visualization in regard to text, animations, UI and design. We user tested the interactivity in each iteration to ensure that the graphic was easy to understand and to use.

The visualization was developed using HTML, CSS and JavaScript (ES2015). We used the D3js-library to draw the bar-chart and noUiSlider to create a slider working seamlessly with all platforms. We ran into an all too well known problem on smartphones, which was showing additional information about the bar-chart. This is normally done by clicking a bar and getting some kind of information in a pop-up-box. On desktop this is done by hovering, but we wanted to try something new on smartphones: we used the DeviceOrientation-API to create a hover-box that shifted around by tilting your phone. This ensured an easy and very useable way of interacting with the bar-chart.

Data

We acquired data from Statistics Denmark.

Resources

One journalist, one grapich designer, one editor and two programmers worked two week with this project.

Impact

The application was one of the most read articles at dr.dk. Actually the application was the 19th most read article in 2016 at dr.dk.

The purpose of making users guess how many people earns less than them was to open their eyes to the fact that they were probably better off than they thought. And it worked. Three out of our users were told, that more people make less than them, compared to what they guessed.
