What We Do

The Office of Policy Analysis serves the Nation and works to advance the mission of the Department of the Interior, which:

  • protects and manages the Nation’s natural resources and cultural heritage;
  • provides scientific and other information about those resources; and
  • honors its trust responsibilities or special commitments to American Indians, Alaska Natives, and affiliated Island Communities
