A census tract, census area, or census district is a particular community defined for the purpose of taking a census. Usually these coincide with the limits of cities, towns or other administrative areas and several tracts commonly exist within a county. In unincorporated areas of the United States these are often arbitrary, except for coinciding with political lines.

Alaska

---

Unlike any other U.S. state, Alaska is not entirely divided into county equivalents. Most of Alaska's area is not contained within one of the state's 16 boroughs. This area, referred to by the Alaskan government as the Unorganized Borough, has been divided into census areas by the United States Census Bureau. These census areas have no government of their own; they exist solely to facilitate Census Bureau operations.
