About OpenSpending

OpenSpending exists to “map the money worldwide” – that is, to track and analyse public financial information globally. Concretely, OpenSpending is:

  • A central, high-quality, open database of public financial information, including budgets, spending, balance sheets, procurement etc
  • A community of users and contributors to this database
  • A set of open resources providing technical, fiscal, and political understanding necessary to work with financial information.

The OpenSpending database is a resource for the many individuals and groups who wish to discuss and investigate public financial information, including journalists, academics, campaigners, and more.

Project Principles

OpenSpending is guided by its community principles.

  • Open materials. All material created within the project will be open data and open content built with open tools. All project data is made available under the Open Database License or another Open Data Commons license.
  • Open community. Anyone interested in financial data can contribute. We’re friendly to newcomers and old hands alike—everyone was new once, and we value all levels of experience.
  • Doing. Our focus is on the concrete, not the abstract, and on making rather than theorizing.


The OpenSpending project is community-run and operates with the institutional support of the Open Knowledge Foundation. See the governance page for details.
