Country subdivision

A country subdivision is a subdivision of a country's territory. As such it can, apart from land-based territory also include territorial waters.

Subdivisions of a country's territory exist to support specific tasks. Local government, postal addressing, observance of official time, gathering information for census or votes in elections or arrangement of competitions are tasks for which countries are often subdivided into smaller parts.

In some countries certain subdivisions are used for a large variety of tasks, e.g. the territories defined by the departments of France, primarily existing as administrative subdivisions, are also used for postal code zones and have been used as primary zones for geographic telephone numbers in France.

Comparison with other geographic areas

A country subdivision is an abstract creation and distinct from a landform as studied in physical geography, e.g. a basin, a desert, a forest, a valley. Nevertheless, the border of a country subdivision can be influenced by physical characteristics of an area or also match the borders of a landform exactly.

Type of area	Abstraction	Examples
Group of countries	abstract	European Union, Eurozone, Union of South American Nations
Country	abstract	Australia
Country subdivision	abstract	Artemisa Province, United States Court of Appeals for the First Circuit
Landform	non-abstract	Atlantic Ocean, Amazon Basin, Africa

Amount of tasks, changes of tasks

The amount of tasks performed within the borders of a specific country subdivision varies, e.g. the departments of France had been used not only as a basis for enacting laws but also car license plates, telephone number prefixes and postal code zones were based on the departmental borders.

Some entities also lose certain functions, e.g. the Traditional districts of Denmark, have once been administrative but are now only used to identify location in some cases. A similar loss of functionality applies to the counties in England, now named ceremonial counties.
