Overview
Data.gov is the U.S. federal government’s official open data website, designed to make government more open and accountable by providing free public access to federal datasets. Originally launched in 2009 following a presidential directive for greater transparency, the platform operates under the OPEN Government Data Act of 2018, which legally requires federal agencies to publish their data online in standardized, machine-readable formats. The site promotes citizen participation in government, economic development, and informed decision-making across both public and private sectors, with the General Services Administration (GSA) responsible for maintaining the central catalog 1,3.
Data.gov extends beyond federal data by collaborating with state, local, and international sources to build a comprehensive multi-level government catalog. The platform’s open source foundation allows governments worldwide to adapt its code for their own initiatives. The source code is available on the GSA GitHub repository, and a complete listing of international and U.S. open data sites can be found on the Open Data in the United States and Internationally page 2,2.
