About the Humanitarian Data Exchange

Learn HDX works with humanitarian data.

The Humanitarian Data Exchange (HDX) is an open platform for sharing data across crises and organizations. Launched in July 2014, the goal of HDX is to make humanitarian data easy to find and use. HDX has been accessed by millions of users in over 250 countries and territories and brings together more than 20,000 datasets from hundreds of partners.

HDX is managed by the United Nations Office for Coordination of Humanitarian Affairs’ (OCHA) Centre for Humanitarian Data, which is located in The Hague, the Netherlands. OCHA is responsible for coordinating humanitarian actors to ensure a coherent response to emergencies. The HDX team spans North America, Europe, Africa, the Middle East and Asia.

We define humanitarian data as:

• data about the context in which a humanitarian crisis is occurring
• data about the people affected by the crisis and their needs
• data about the response by organizations and people seeking to help those who need assistance
