This is our pick for the #DJA2017

May 22, 2017

After revising GEN’s choices, we’ve come with our own pick for each category.

The GEN Summit published the past Tuesday the shortlist of most outstanding projects submitted to the Data Journalism Awards 2017 competition.


Winning projects will receive a prize worth $1801(US) each (that’s $18 000 in total) at the DJA 2017 Ceremony in Vienna, on 22 June 2017, during the seventh annual GEN Summit.


This year, 573 projects were submitted, from 51 countries, representing the 5 continents. That’s over 20% more than last year and the highest number of entries the Data Journalism Awards competition ever received.


The list shows top projects for each of the 10 categories GEN in awarding this year: Data visualisation; Investigation; News data app; Open data; Data journalism website; Best individual portfolio; Best team portfolio; Public’s choice; Small newsrooms; Student and young data journalist, and The Chartbeat Award for the best use of data in a breaking news story, within first 36 hours.


Between the nominees, the American news media standout: The Washington Post, FiveThirtyEight and The Wall Street Journal have 3 nominations each. Regardless of this, several Iberoamerican initiatives have been selected: projects from La Nación (Argentina), El Confidencial (España), La Nación (Costa Rica), Rutas del Conflicto (Colombia) or Folha de S.Paulo (Brazil) are some of the nominees.


After revising GEN’s choices, we’ve come with our own pick for each category:


Data visualisation

Gun Deaths in America, FiveThirtyEight, United States

This #dataviz is a great example of simple interactives to help readers understand complex statistics. The viz is part of a bigger series of stories that tackle the different solutions that must be taken into account to face gun deaths in the United States. This product tells a story by itself but also serves as an introduction, and allows the users to explore the data by themselves. Also, the methodology piece is great!


The death of a prosecutor, 40,000 audio hearings, 2 years, a team and a news app, LA NACION DATA, Argentina

This was a tough call. But we chose the investigation done by La Nación because it highlights different aspects que consider fundamental when doing journalism:

  1. They didn’t publish the information as it came once the audios were filtered to the public, they strive to find connections and stories behind them.

  2. It was a collaborative effort that included journalist, students, and NGOs. Citizens were encouraged to complement stories with the information they had.

  3. They investigation was conducted under political pressure while many political or social changes occurred in the country.

  4. The project was tackled with basic #ddj tools: the important thing was the story behind the information, not the technology.


News data app

Blue Feed, Red Feed, The Wall Street Journal, United States

Most of the projects nominated in this category presented apps related to the US Elections. This is a very innovative app that shifts attention from the “Trump vs. Hillary” fight and tackles a very important issue: social media framing and how hard it is for users to get out from that bubble an algorithm has designed for them. It is a very innovative piece, made with simple tools and lots of creativity.


Open data

Analyzing 8 million data from public speed limit detectors radars, El Confidencial, Spain

This piece was one of our favorites because the information was acquired thanks to different FOIs. The data analysis is great and presented in a simple way for users, and the result was clear for El Confidencial: the piece was read by more than 220.000 unique users, totaling more than 246.000 page views.


Data journalism website

Rutas del Conflicto, Rutas del Conflicto, Colombia

The different projects in this category were all great and diverse. But we chose the Colombian project because it reflects a very challenging effort: to assure the construction of memory and reveal the truth in Colombia’s conflict. Getting the information has required investigative journalism, FOIs request, data journalism and lots of collaboration with NGOs, citizens, and other reporters. The information presented on the Web has never been presented by the Government or any other organization in such way.

The Chartbeat Award for the best use of data in a breaking news story, within first 36 hours

Fact Check: Trump And Clinton Debate For The First Time, NPR / NPR Visuals & NPR Politics, United States


The effort made by the NPR team was outstanding. They not only transcripted everything that was happening in the debate but had editors and reporters fact checking in real time what the candidates were saying. Their comments not only showed how true or false a statement was but also gave context and shared links with the audience so that they could understand better what the issues they were tackling were.
