Data journalism is all about uncovering truths through numbers, transforming raw data into meaningful stories that inform, engage, and inspire audiences. A compelling example is Helsinki’s milestone of going a full year without a single traffic fatality as highlighted in a recent story.
At first glance, this fact, zero traffic deaths in 12 months, may sound straightforward. But the deeper story lies in the data behind this success and how it illuminates the factors contributing to it.
By showing that more than half of the city’s streets now have a 30 km/h speed limit, compared to mainly 50 km/h limits fifty years ago, these figures paint a clear picture of how traffic policies have evolved over time. This comparison helps readers grasp the scale and impact of safety improvements, grounding the story in measurable change rather than vague statements.Why does this story resonate so well for data journalism learners?
- Data Makes the Abstract Tangible: “Zero traffic deaths” is a powerful headline number that captures attention. Yet the story goes beyond that, sharing how injury-causing accidents have dramatically dropped from nearly 1,000 annually in the 1980s to just 277 in the past year, with no pedestrian deaths since 2019. Such numbers allow readers to grasp the magnitude of progress.
- Data Uncovers the Why and How: The story explains what interventions worked, supported by data on speed limits, traffic camera enforcement, and infrastructure upgrades. This empowers readers to appreciate the causal links and ongoing commitment needed for sustained success.
The story’s inclusion of injury-causing traffic accidents alongside fatalities adds important depth to the data narrative. Highlighting the drop from nearly 1,000 injurious accidents in the 1980s to just 277 in the past year shows that the positive safety trend goes well beyond zero deaths.

In data journalism, these kinds of numbers are essential because they provide context, illustrate cause and effect, and engage readers in a meaningful way by explaining developments with precision and clarity.
Key takeaways for aspiring data storytellers:
- Start with a compelling data point that sums up the story, but always dig deeper to find the supporting numbers that explain it.
- Provide historical context and comparisons to enrich the narrative and help the audience understand significance.
- Explain the data’s implications—what does it mean for communities, policies, or the future?
- Use credible sources and expert commentary to back your data and build trust.
- Make data relatable and human-centered by connecting statistics to real-world impacts and people’s lives.
In the world of data journalism, numbers are not just figures, they are the key to unlocking stories that matter, guiding readers through complexity with clarity, and shedding light on progress and challenges alike.
