American Samoa is administratively divided into three districts (Western, Eastern and Manuʻa) and two unorganized atolls (Swains Island and Rose Atoll).

[8] For statistical purposes, the United States Census Bureau counts the three districts and two unorganized atolls as five county equivalents, while treating the actual counties as minor civil divisions.

[20]The U.S. National Park Service says the following about the structure of villages in American Samoa:[21] In general each village is made up of a group of aiga (extended families) which include as many relatives as can be claimed.

Each aiga is headed by a matai (chief) who represents the family on all matters including the village council, or fono.

Matais hold title to all assets of the aigas, or families, they represent and are responsible for law enforcement and punishment of infractions occurring in their villages.
