Turkey is divided into provinces on the basis of “geographical situation”, “economic conditions”, and “public service” requirements.

Under the Law on Provincial Administration (No 5442) lower levels of provinces are laid down as sub-provinces and districts.

The administration of the provinces is based on the principle of devolution of powers.

The mayor is the chief executive of the province and is responsible for the coordination and cooperation of government authorities within the province.

Central administrative organizations comprising several provinces may be established to ensure efficiency and coordination of public services.
