This document provides an introduction to data journalism. It discusses how data journalism has existed for a long time but is now easier with computers and tools. Data journalism collects, analyzes, and visualizes data to tell stories in an understandable way. Good data journalism starts with a research question and uses reliable, reusable data sources. Examples provided analyze social phenomena across locations and over time, and how vaccines impacted disease rates in the US. Civic participation can also contribute to data journalism investigations.
ASOCEU - Lesson 2 - Data Journalism Part One (slides)
- 1. WHAT IS DATA JOURNALISM (part one)
- 2. WHAT IS DATA JOURNALISM (part one)
- 3. WHAT IS DATA JOURNALISM: INTRODUCTION 1858: Florence Nightingale writes a report on the condition of English soldiers in the Crimea, analysing the leading causes of death.
- 4. WHAT IS DATA JOURNALISM: INTRODUCTION 1821: the first edition of the Guardian publishes a table listing all schools in Manchester, with the costs and number of students.
- 5. WHAT IS DATA JOURNALISM: INTRODUCTION 2000s: Simon Rogers (Guardian Datablog) reproduces the table published in 1821 using simple Data Visualisation tools
- 6. WHAT IS DATA JOURNALISM: INTRODUCTION Data Journalism is not new: you could say that it has existed as long as data has. The difference is that in the past the data were published in very costly books, now computers with spreadsheets and specific tools do half the work by themselves.
- 7. WHAT IS DATA JOURNALISM: INTRODUCTION Today, Data Journalism is a form of journalism that: ● Collects, cleans and analyses data ● Uses new technologies ● Translates data into information, visualisations, analyses… in a few words: TELLING STORIES (in the most understandable way possible)
- 8. WHAT IS DATA JOURNALISM: INTRODUCTION Starting point… Data are the raw material for a data journalist. As in traditional journalism, it’s also important to start out with a good research question, identify the story that you want to tell and understand the final objective of the project.
- 9. WHAT IS DATA JOURNALISM: INTRODUCTION Think like a journalist… The data journalist, usually, thinks about data as a journalist would and not as an analyst. Why are some numbers interesting? What's in there that’s new? What might happen if it’s crossed with other data? Answering these questions is the most important thing.
- 10. WHICH DATA?
- 11. WHAT IS DATA JOURNALISM: WHICH DATA? Data useful for our research: ● Associated with economic or social issues ● Taken from reliable sources ● Reusable (published by sources with licences for reuse) ● Can be aggregated, when we can build them ourselves by putting multiple sources together
- 12. WHAT IS DATA JOURNALISM: WHICH DATA? The tools you need ● Spreadsheet (Excel or Libre Office Calc) which allows you to analyse small or large scale tables ● Software and applications that allow you to visualise the data we have aggregated using maps or graphs
- 13. SOME EXAMPLES
- 14. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS Analyse a social phenomenon across territories ● The aim is to compare different geographical areas in terms of a phenomenon ● We require and need to make uniform data for all territories that we wish to compare ● They need to be compared starting from a common element (in relation to the population, for example)
- 15. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS Example: investigation into confiscated Mafia assets https://www.confiscatibene.it
- 16. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS The results of the analysis allow you to: ● Understand whether a phenomenon has a greater incidence in one territory rather than another ● Evaluate – given these differences – whether it is necessary to look for and analyse new data to understand whether there is correlation with other phenomena.
- 17. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS The development of a phenomenon over time ● Given a certain phenomenon, the aim is to understand how it recurs over time
- 18. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS Some examples ● An accident occurs on a section of road: is it the first time this happened or is that section often affected by similar events? ● A flood causes damage: was it more intense than similar episodes or is it a territorial/town-planning problem?
- 19. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS The example: the impact of vaccines in the 20th century ● What was the trend of infectious diseases in the United States? ● What impact have vaccines had on individual diseases? ● Are there other significant territorial differences in proportion to the number of infected people? ● Are there some interesting outliers?
- 20. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS Interactive heat maps showing the number of infected people, measured over a period of 80 years (from 1930 to 2010) in 50 American states. How have infections diminished following the introduction of vaccines?

- 21. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS Civic and participatory journalism Many Data Journalism investigations, especially those related to government transparency, spring from an organised system of information exchange, where researchers, sociologists, experts or lay citizens who are passionate or interested about the topic, work alongside journalists.
- 22. SOME EXAMPLES: DATA JOURNALISM INVESTIGATIONS The VozData initiative in Argentina, a platform that combines participation in civic monitoring with data journalism investigations.
