An autonomous administrative division (also referred to as an autonomous area, zone, entity, unit, region, subdivision, province, or territory) is a subnational administrative division or internal territory of a sovereign state that has a degree of autonomy—self-governance—under the national government. Autonomous areas are distinct from the constituent units of a federation (e.g. a state, or province) in that they possess unique powers for their given circumstances. Typically, it is either geographically distinct from the rest of the state or populated by a national minority, which may exercise home rule. Decentralization of self-governing powers and functions to such divisions is a way for a national government to try to increase democratic participation or administrative efficiency or to defuse internal conflicts. States that include autonomous areas may be federacies, federations, or confederations. Autonomous areas can be divided into territorial autonomies, subregional territorial autonomies, and local autonomies.
Guernsey, the Isle of Man, and Jersey are self-governing Crown Dependencies which are not part of the United Kingdom; however, the UK is responsible for their defence and international affairs.
Gibraltar is a self-governing overseas territory of the UK. Most of the other 13 British Overseas Territories also have autonomy in internal affairs through local legislatures.
Aruba, Curaçao, and Sint Maarten are autonomous countries within the Kingdom of the Netherlands, each with their own parliament. In addition they enjoy autonomy in taxation matters as well as having their own currencies.
The French Constitution recognises three autonomous jurisdictions. Corsica, a region of France, enjoys a greater degree of autonomy on matters such as tax and education compared to mainland regions.[citation needed] New Caledonia, a sui generis collectivity, and French Polynesia, an overseas collectivity, are highly autonomous territories with their own government, legislature, currency, and constitution. They do not, however, have legislative powers for policy areas relating to law and order, defense, border control or university education. Other smaller overseas collectivities have a lesser degree of autonomy through local legislatures. The five overseas regions, French Guiana, Guadeloupe, Martinique, Mayotte, and Réunion, are generally governed the same as mainland regions; however, they enjoy some additional powers, including certain legislative powers for devolved areas.
New Zealand maintains nominal sovereignty over three Pacific Island nations. The Cook Islands and Niue are self-governing countries in free association with New Zealand that maintain some international relationships in their own name. Tokelau remains an autonomous dependency of New Zealand. The Chatham Islands—despite having the designation of Territory—is an integral part of the country, situated within the New Zealand archipelago. The territory's council is not autonomous and has broadly the same powers as other local councils, although notably it can also charge levies on goods entering or leaving the islands.[5]
In Ethiopia, "special woredas" are a subgroup of woredas (districts) that are organized around the traditional homelands of specific ethnic minorities, and are outside the usual hierarchy of a kilil, or region. These woredas have many similarities to autonomous areas in other countries.
Other areas that are autonomous in nature but not in name are areas designated for indigenous peoples, such as those of the Americas:
Denmark has established very specific territorial autonomies with its two island territories
Faroese and Greenlandic are seen as official regional languages in the self-governing territories belonging to Denmark.
Greenland [...] is an autonomous territory within the Kingdom of Denmark
The Faroe Islands [...] is one of three autonomous territories in the Nordic Region
