UIA's Database
The UIA’s database is continuously updated and comprises two main data sets:
- Organizations – over 78,500 descriptive profiles of international associations
- Events – over 572,000 past and future international events of these associations
The UIA keeps annual snapshots of the data sets which also enables comparison across years.
Customized extractions are the most flexible and powerful method to access UIA’s data based on specific criteria meeting your needs.
You can also subscribe to the database – online or in print. For information on subscriptions, please ask UIA for more information or see: Associate Membership.

Expanded Yearbook Online via API
The data found in UIA's Yearbook of International Organizations will soon be accessible via a REST API for easier statistical and network analysis by researchers. This service, new in 2026, will contain the current Yearbook data (as provided via our online subscription) as well as profiles from published Yearbooks of past years, back to 2002. Users will be granted access to the API via a system of credits, with details for pricing and tiers still to be determined.
