A government agency is a permanent or semi-permanent organization within a national or state government. These agencies are responsible for oversight or administration of a specific sector, field, or area of study. Most government agencies are meant to be non-political but the direction and intention of their work may change depending on which political party makes up the majority of elected officials.
The work of many government agencies is mandated and directed by law. Agencies may work individually on in cooperation with other agencies or non-government entities on their assigned work.
