Open Data

Welcome to the USITC's Open Data webpage

Open data refers to publicly available data structured in a way that enables data to be discoverable and usable by end users. The Administration has taken steps to make government-held data more accessible to the public for innovation and economic growth. On May 9, 2013, the President signed an executive order that made open and machine-readable data the new default for government information. Making information about government operations more readily available and useful is core to the promise of a more efficient and transparent government. Explore our open data catalog at, which uses the common core metadata schema for federal agency open data listings.
