Finding stories in numbers
Data journalism uses datasets—spreadsheets, records, and databases—as a primary source for reporting. Instead of relying only on interviews and documents, data journalists analyze numbers to find patterns, verify claims, and reveal stories hidden in large volumes of information.
It combines traditional reporting skills with data analysis, letting journalists answer questions like whether a policy actually worked, or how a problem is distributed across a population.
How data journalism works
A typical project involves acquiring data (often through public records requests), cleaning and checking it for errors, analyzing it for meaningful patterns, and then communicating findings clearly—frequently through charts, maps, and interactive graphics.
Rigor is essential at every step. Messy data, flawed methods, or misleading visualizations can produce false conclusions, so data journalists document their analysis and often publish their methodology.
Why it matters
Data journalism can uncover stories no single source could reveal—systemic patterns of inequality, safety failures, or misconduct that only become visible at scale. It has powered major investigations and made complex issues concrete and visual.
It also strengthens accountability: hard numbers are harder to dismiss than anecdotes, and transparent analysis lets readers check the work themselves.
Reading data-driven stories
To evaluate data journalism critically:
- Check where the data came from and how complete it is
- Look for the methodology or source notes
- Watch for misleading charts—truncated axes or cherry-picked ranges
- Remember that correlation in data is not proof of causation
Key takeaways

Frequently asked questions
Do data journalists need to code?
Many use tools ranging from spreadsheets to programming languages, but the core skill is rigorous analysis and verification. Some projects need only careful spreadsheet work; others require coding.
How can data journalism mislead?
Incomplete data, flawed methods, or deceptive charts can create false impressions. Reputable data journalism documents its sources and methodology so readers can scrutinize the analysis.
