Development questions meet development data.

The next Development Data Challenge will be held in Helsinki as part of the Open Development topic stream at Open Knowledge Festival 17-21 September 2012. Hope to see you there!

Calling all development experts, coders, designers, data wranglers and YOU.

Join us for the Development Data Challenge! We want to help answer your questions about development.

Do you know of any interesting and relevant datasets? Can you clean and wrangle data? You might be able to turn that data into an awesome app. Maybe you can make data look beautiful and tell an amazing story. Or maybe you just have a great idea.

Whatever your interests, skills or background, we want you to get involved.

Visit the Questions page to tell us what you want to know about international development. Don’t be shy – we want lots of questions, data, code and feedback.

We’re holding several hackdays in various locations to solve development data challenges. Visit the events page for more about dates and locations. We’ll see you there.

Contact Mark Brough at if you have any other questions.
