Open government data is government-produced information that anyone can freely use, modify, and share for any purpose. For example, the Treasury Department publishes open data on its new USAspending.gov website, which provides detailed information to help track government spending.

Open data can foster accountability and public trust by giving citizens information about government activities and results. It can also promote private sector innovation and help industries generate revenue, such as by providing demographic, financial, or geographic information. For example, some real estate websites use Census data to provide information on the neighborhoods where homes for sale are located.

The GAO recently reported on ways that the U.S. Treasury may more transparently and effectively share government data through five key practices. While the report addresses federal data, the recommendations and insights may be relevant to a variety of state and local government functions.
