About WDL

World Data League (WDL) was an international non-profit competition that gathered the best minds in the data science field to develop long-lasting solutions for social impact challenges.

We dreamt big and wanted to be part of the solution. For that, we picked topics related to the United Nations Sustainable Development Goals and used real-world challenges provided by our partners.

For 3 editions - from 2021 to 2023 - we gathered data scientists, data science companies, and topic entities - institutions working on the challenges’ subjects, and everyone won something.

Once each edition finished, we shared the insights and results with the world, and now you can find them categorized on this website. The competition has ended, but all World Data League knowledge became public to be used at no cost by anyone, anywhere.

In 2021, WDL was featured on the list of
Top 100 AI solutions for Sustainable Development by IRCAI, UNESCO International Research Centre on Artificial Intelligence.
Over 3 editions…
Meet all the entities that provided us with challenges and data.
World Data League wouldn’t have been possible without the institutions that shared with us their challenges and also their data. More than providers of the means for the competition, they illustrated the mission behind it: to use data to solve social impact challenges.
Meet the people behind the project.
From the first members to the new additions, all these people contributed to the organization of one or more editions of the World Data League.
