If we understand how governments spend public money, we can have a say in how that money is used. OpenSpending is the tool that can help us to do that.
It is an open resource for people and groups who wish to track and analyse public financial information (budgets, spending, balance sheets, procurement etc.).
To help you do this more easily, OpenSpending comes with a very useful set of tools that provide the understanding – technical, financial, political – needed to work with financial information of this type.
