Meet the 2023 Matilda data visualisation competition winners

13 December 2023
Australian students flex their data viz skills, telling us important stories about mental health and substance use
Since 2022, the Matilda Centre has run an annual data visualisation competition encouraging Australian university students to transform mental health and substance use data into meaningful and accessible visualisations. We are happy to announce the 2023 winners in our three categories: Judge’s Choice, People’s Choice, and Best Beginner.

Mental illness and substance use are increasingly urgent public health concerns in Australia. Research is abound with the impacts and what can be done about it. 

So, how can we go from numbers on a page to getting the public and policymakers to see the big picture?

Visual storytelling can powerfully and effectively communicate complex messages. Providing students with the opportunity to develop and showcase those skills, the Matilda Centre held a competition asking students to identify issues they thought we needed to know about, and to turn that data into a compelling visual narrative.

Judged across three categories – Judge’s Choice, People’s Choice, and Best Beginner, we were thrilled with the quality of the submissions and the stories told.

The 2023 winners were announced on social media in November and are available below.

The visualisation includes a map of the earth with countries coloured in different rates corresponding to rates of death by suicide. The key highlights include the United States, who are the only country coloured with over 40,000 deaths a year.

Other highlighted countries include Russia with over 20,000 deaths, the United Kingdom and Brazil with over 10,000 deaths a year, and countries within Europe, Australia, Canada, South America, Africa, and several countries in Asia.

The full visualisation allows viewers to adjust the data based on year (from 2017-2021), age and sex demographics, type of death (suicide or substance use), and the comparison of total deaths v deaths per 100,000 people.

  • the Gospel genre was associated with lower levels of mental ill-health, with Rock and Lofi associated with higher levels of self-reported depression and anxiety
  • Most popular genres included Rock (25.54%), Pop (15.49%), and Metal (11.96%)
  • Listening to music overwhelmingly supported improvement in mental health, but Lofi and Gospel were 100% improvement in self-reporting. Video Game Music had the least effect with 9% reporting it made their symptoms worse
