What a data journalist actually does
A data journalist finds stories in numbers. That means obtaining datasets — through FOI requests, government data portals, company accounts, court records, or proprietary databases — cleaning and analysing them, and then turning the findings into journalism that audiences can understand and that editors will publish. The best data journalism makes complex data sets legible through clear writing and well-designed visualisations.
Data journalism in the UK sits across a spectrum: at one end, a regional reporter who uses spreadsheets to analyse FOI returns; at the other, a graphics developer at a national outlet writing Python scrapers to analyse hundreds of thousands of court records. Most working data journalists operate somewhere in between, combining solid spreadsheet skills with visualisation tools, confident FOI use, and strong reporting instincts.
The data journalism skills stack
Foundation (all data journalists)
- ✓Excel and Google Sheets — pivot tables, VLOOKUP, filtering, sorting, basic formulas
- ✓FOI mastery — knowing what to request, how to frame requests, and how to appeal refusals
- ✓Datawrapper and Flourish — the standard visualisation tools for UK news organisations
- ✓Data cleaning — recognising and handling messy, incomplete, or inconsistent data
Intermediate (most data roles)
- ✓SQL basics — querying databases, joining tables, filtering and aggregating data
- ✓OpenRefine — data cleaning at scale
- ✓QGIS or Mapbox — for mapping and geographic data journalism
- ✓Understanding of statistical concepts — averages, medians, rates, significance
Advanced (senior and specialist roles)
- ✓Python (Pandas, BeautifulSoup, Selenium) — data analysis and web scraping
- ✓R — statistical analysis, ggplot2 for visualisation
- ✓D3.js — custom interactive data visualisations for web publication
- ✓Web scraping and API use — automated data collection at scale
When data journalism skills open doors
- 1Applying for any data or visual journalism role at a national or major regional outlet — these roles are still relatively rare and well-paid.
- 2Differentiating yourself as a general reporter by using data analysis in your regular reporting.
- 3Investigating public interest stories that require analysis of large datasets — FOI responses, government spending, court records.
- 4Bureau Local collaborations — data skills open you up to funded collaborative journalism projects.
- 5Freelance pitching — a story backed by your own original data analysis is far easier to sell than a tip-off.

Red flags in data journalism
- Using percentages without checking absolute numbers — a 100% increase from 1 to 2 is not a story.
- Presenting correlation as causation in data analysis without appropriate caveats.
- Using imprecise language like "soared" or "plummeted" for changes that are statistically modest.
- Ignoring the methodology of datasets you are using — what is actually being measured and how?
- Using pie charts for more than three categories — a classic data visualisation error that editors notice.
- Not checking your FOI data against the original source for errors or misclassifications.
- Assuming publicly available government data is accurate and complete without checking methodology notes.
Data journalism career checklist
- Confident with Excel and Google Sheets — pivot tables, VLOOKUP, basic formulas.
- Have submitted at least five FOI requests and received responses.
- Have produced at least one data visualisation using Datawrapper or Flourish.
- Have completed at least one free data journalism course (IRE, GIJN, EJC/GNI).
- Have a published data story — even at a student or hyperlocal level.
- Understand the difference between mean and median and when each is appropriate.
- Have a public portfolio including at least two data-driven stories or projects.
- Have joined the Data Journalism UK community or Bureau Local network.

Common mistakes in data journalism careers
- Over-prioritising coding at the expense of journalism instincts — the story comes first.
- Building elaborate visualisations without checking whether the underlying data is reliable.
- Not explaining your methodology — data journalism requires showing your working.
- Ignoring FOI as a data source — government data portals are not the only route to analysis.
- Treating Python or R as a prerequisite before developing spreadsheet and FOI skills.
- Not publishing your data or methodology alongside the story — transparency is a professional standard.
- Skipping the statistics fundamentals — understanding confidence intervals and sample sizes is not optional.
