🪓 Data Journalism Unit 1 – Data Journalism: Defining the FieldData journalism merges traditional reporting with data analysis and visualization to uncover stories and provide evidence-based reporting. It uses large datasets to identify trends and insights, making complex information accessible through visualizations and interactive features.
This field requires a mix of journalistic skills, data literacy, and technical proficiency. It contributes to transparency and accountability in various sectors by empowering readers to explore data and understand complex issues more deeply.
What is Data Journalism?
Combines traditional journalism with data analysis and visualization to uncover and communicate stories
Utilizes large datasets, often from public sources, to identify trends, patterns, and insights
Enables journalists to provide more accurate, in-depth, and evidence-based reporting
Example: Analyzing government spending data to identify misuse of public funds
Requires a combination of journalistic skills, data literacy, and technical proficiency
Aims to make complex information more accessible and understandable to the general public
Uses data visualizations (charts, graphs, maps) to convey information effectively
Empowers readers to explore and interact with data through interactive features and tools
Contributes to increased transparency and accountability in various sectors (government, business, healthcare)
Key Concepts and Terminology
Dataset: A collection of related data points organized in a structured format
Data cleaning: The process of identifying and correcting errors, inconsistencies, and missing values in a dataset
Data analysis: Examining and interpreting data to derive meaningful insights and conclusions
Data visualization: Representing data visually using charts, graphs, maps, and other graphical elements
Examples: Bar charts, line graphs, scatter plots, heat maps
Open data: Data that is freely available for anyone to use, modify, and share without restrictions
Application Programming Interface (API): A set of protocols and tools that allows different software applications to communicate and exchange data
Data scraping: Extracting data from websites or other digital sources using automated tools or scripts
Statistical analysis: Applying mathematical and statistical methods to analyze and interpret data
Historical Context and Evolution
Data journalism has roots in computer-assisted reporting (CAR), which emerged in the 1960s
CAR involved using computers to analyze data for journalistic purposes
The rise of the internet and digital technologies in the 1990s and 2000s made data more accessible
Enabled journalists to access and analyze larger datasets more efficiently
Open data initiatives and freedom of information laws have increased the availability of public data
Examples: Data.gov in the United States, Data.gov.uk in the United Kingdom
High-profile data journalism projects have demonstrated the power and impact of the field
The Guardian's "The Counted" project tracked police killings in the United States
