Data journalism is a form of investigative journalism that tells a story through graphs, maps and other infographics. Peter Aldhous, a US-based journalist, says it is also a form of investigative journalism. It isn’t just about the figures but a good data story is a combination of various elements that are explored below.
Know where to find data
Adi Eyal, the director for Code for South Africa, an organisation pushing for open data, says the starting point in looking for data is online.
Finding data online is ideal for journalists working in Africa where some governments have put controls on the type of information that can be released.
Eyal’s organisation created a site that provides information about ward councillors in Western Cape and the projects that they are working on. Some of the data was scrapped from the website of the City of Cape Town and some came from government departments. Eyal says looking for data from various sources to use in a single data story is ideal for journalists.
“There is a lot of data available. Look for data from all sorts of places,” he says.
Countries like Kenya have made it easy by creating its own open data site. In South Africa, the Promotion of Acccess to Information Act enables data enthusiasts and journalists to access information from state departments.
It doesn’t end with finding the right sources of data. Quite often the data comes in a format that is not easy to extract and analyse.

There are also various free tools that allow journalists and other users to extract data. These include outwit hub, google refine and import.io. Using them requires knowledge. Code for South Africa is part of a network of African open data organisations. Other networks are in Ghana, Nigeria and Kenya and they provide training to help journalists acquire such skills.
EJN also provides training and online resources that journalists can use. One such resource is the geojournalism handbook, which provides tutorials. Data journalism writer and trainer Paul Bradshaw also provides tutorials on his online blog.
Query the data
Aldhous says querying the data is an important part of the journalistic process. Most journalists don’t have these kind of skills but will need to “befriend” a scientist who can help with the statistical analysis of the data, says Steve Connor, the science editor for The Independent.
- Don’t take the data at face value
Querying would involve being aware of problems the data set has.
“What is missing from it? What errors does it have? Question everything. Check it out. If your mother says she loves you, you check it out,” Aldhous says.
Analysis and visualisation
Querying also involves analysis to see what trends are derived from it. Providing it in a tabular form or in an excel document can be quite daunting for the reader. There are data tools that are available that help journalists to visualise their data in a way that makes it palatable and easy to read. Such tools include Datawrapper, Geobatch, and Tableau.
Writing the story
A data story isn’t just about the numbers. Brad Parks, the executive director of AidData, a good data story has to “break it down to something understandable.” It must be relevant and timely too, he says.
Aldhous says it must be accompanied by a compelling narrative that would be easy and enjoyable to ready.
