government agency
A government agency or state agency, sometimes an appointed commission, is a permanent or semi-permanent organization in the machinery of government (bureaucracy) that is responsible for the oversight and administration of specific functions, s ...
in charge of the municipal affairs of the
Istanbul Province. It is one of the 30
metropolitan municipalities in Turkey.
History
The Istanbul Metropolitan Municipality was established on 23 March 1984, following the enactment of the metropolitan municipality act on 8 March 1984. Initially, the municipality covered only the urban centers of Istanbul, which accounted for 35% of the Istanbul Province. The rest of the province was administered by the
Istanbul Special Provincial Administration.
In July 2004, the concept of metropolitan municipality was redefined in Istanbul and
Kocaeli, where thenceforth metropolitan municipality borders would overlap with provincial borders.
This change enabled the Istanbul Metropolitan Municipality to extend its jurisdiction to the whole province, and to assume the responsibilities of the provincial government. The Istanbul Metropolitan Municipality now concentrates the competences of public management, while the Istanbul Special Provincial Administration's duties are limited to the building and maintenance of schools, residences, government buildings, and roads, and the promotion of arts, culture, and nature conservation.
Organization
The Istanbul Metropolitan Municipality is divided into
39 district municipalities, which are the second-level local governments within the province. Each district municipality has its own mayor and council, elected by the local voters. The district municipalities are responsible for providing municipal services, such as water, sewerage, waste management, social assistance, health, education, culture, sports, and transportation, within their boundaries.
As of 2024, the Istanbul Metropolitan Municipality is organized as follows:
