We're trying to gather the world's spending information in a common database so that we can provide common tools for analysis, visualization and comparison. OpenSpending is an open platform that aims to facilitate the presentation of financial information so anyone - whether data geek or concerned citizen - can contribute their local city budget or spending reports.
There are many projects that aim to track financial information. All require these basic services, which we aim to provide:

  • Data loading and validation facilities.
  • Common visualization types (treemaps, charts, and the bubble tree).
  • Full-text search for all entries.
  • Means to track provenance and provide access to the raw data.
