An autonomous administrative division (also referred to as an autonomous area, entity, unit, region, subdivision or territory) is a subdivision or dependent territory of a country that has a degree of self-governance, or autonomy, from an external authority. Typically, it is either geographically distinct from the rest of the country or populated by a national minority. 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 and/or to defuse internal conflicts. Countries that include autonomous areas may be federacies, federations, or confederations. Autonomous areas can be divided into territorial autonomies, subregional territorial autonomies, and local autonomies.

Autonomous administrative division Wikipedia
Jersey, Guernsey, and the Isle of Man 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. A number of other British Overseas Territories also have autonomy in internal affairs through local legislatures.New Zealand dependent territories
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.Danish constituent countries
The Faroe Islands and Greenland are two autonomous countries within the Kingdom of Denmark.Dutch constituent countries
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.French overseas collectivities, New Caledonia, and Corsica
The French constitution recognises 3 autonomous jurisdictions. Corsica, a region of France, enjoys a greater degree of autonomy on matters such as tax and education compared to mainland regions. 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, Guadaloupe, 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.
