Census tract

Census tract

A census tract, census area, or census district is a particular community defined for the purpose of taking a census. [cite web

In the United States, census tracts are subdivided into block groups and census blocks.

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.
