District in the context of "Metropolitan area"

The boroughs of New York City are the five major governmental districts that compose New York City. They are the Bronx, Brooklyn, Manhattan, Queens, and Staten Island. Each borough is coextensive with a respective county of the State of New York: The Bronx is Bronx County, Brooklyn is Kings County, Manhattan is New York County, Queens is Queens County, and Staten Island is Richmond County.

All five boroughs of New York came into existence with the creation of modern New York City in 1898, when New York County (then including the Bronx), Kings County, Richmond County, and part of Queens County were consolidated within one municipal government under a new city charter. All former municipalities within the newly consolidated city were dissolved.

The 81 provinces of Turkey are divided into 973 districts (ilçeler; sing. ilçe). In the Ottoman Empire and in the early Turkish Republic, the corresponding unit was the kaza.

Most provinces bear the same name as their respective provincial capital districts. However, many urban provinces, designated as greater municipalities, have a center consisting of multiple districts, such as the provincial capital of Ankara province, The City of Ankara, comprising nine separate districts. Additionally three provinces, Kocaeli, Sakarya, and Hatay have their capital district named differently from their province, as İzmit, Adapazarı, and Antakya respectively.

A capital district, capital region, or capital territory is normally a specially designated administrative division where a country's seat of government is located. As such, in a federal model of government, no state or territory has any political or economic advantage relative to the others because of the national capital lying within its borders. A capital territory can be a specific form of federal district.

A distinction should be made between administrative divisions which include national capitals, but have no special designated status legally (for example, Île de France has no distinct quality from other regions of France). Some federal countries (like Belgium and Germany), give their national capitals the status of full, equal federal units.

The 12 Regions of Morocco are subdivided into 75 second-level administrative subdivisions, the Prefectures and provinces. There are 13 prefectures and 62 provinces. Each prefecture or province is subdivided into arrondissements (only in prefectures of some metropolitan areas), municipalities (communes, sing. commune) or urban municipalities (communes urbaines, sing. commune urbaine) in other urban areas, and districts (cercles, sing. cercle) in rural areas. The districts are subdivided into rural municipalities (communes rurales, sing. commune rural). One prefecture (Casablanca) is also subdivided into préfectures d'arrondissements (sing. préfecture d'arrondissements), similar to districts (cercles) except they are grouping a few arrondissements instead of rural municipalities.

Note: The arrondissements and (urban) municipalities should probably be thought of as fourth-level subdivisions, on the same level as the rural municipalities, but they are not part of any district.

Districts of Switzerland are a political subdivision for cantons. In the federally constituted Switzerland, each canton is completely free to decide its own internal organisation. Therefore, there exists a variety of structures and terminology for the subnational entities between canton and municipality, loosely termed districts. Most cantons are divided into Bezirke (German for districts, singular Bezirk). They are also termed Ämter (Lucerne, singular Amt), Amtsbezirke (Bern, Amtsbezirk), district (in French) or distretto (Ticino and part of Graubünden). The Bezirke generally provide only administration and court organization. However, for historical reasons districts in cantons Grisons and Schwyz are their own legal entities with jurisdiction over tax and often have their own Landsgemeinde.

Seven of the 26 cantons – Uri, Obwalden, Nidwalden, Glarus, Zug, Basel-City and Geneva – have always existed without the district level of government. An eighth one, Appenzell Innerrhoden, uses no intermediate level either, but calls its lowest-level subdivisions Bezirke, although they are functionally equivalent to municipalities elsewhere.

A nāḥiyah (Arabic: نَاحِيَة [ˈnaːħijah], plural نَوَاحِي, nawāḥī [naˈwaːħiː]), also nahiyeh, nahiya or nahia, is a regional or local type of administrative division that usually consists of a number of villages or sometimes smaller towns. The Ottoman nahiye, also called a bucak, was a third-level or lower administrative division, and remains as such in some successor states such as Syria, Iraq, Lebanon and Jordan, with the Balkan states of Serbia and Montenegro having preserved the term for a while after liberation for the highest administrative unit as nahija. In Tajikistan and the autonomous Chinese region of Xinjiang, both from the Turco-Persian or Turkic regions of Asia, it is a second- and third-level division, respectively. A nahiyah can constitute a division of a qadaa, mintaqah or other such district-type division and is sometimes translated as "subdistrict".

Busan (Korean: 부산; pronounced [pusan]), officially Busan Metropolitan City, is South Korea's second most populous city after Seoul, with a population of over 3.3 million as of 2024. Formerly romanized as Pusan, it is the economic, cultural and educational center of southeastern South Korea, with its port being South Korea's busiest and the sixth-busiest in the world. The surrounding "Southeastern Maritime Industrial Region" (including Ulsan, South Gyeongsang, Daegu, and part of North Gyeongsang and South Jeolla) is South Korea's largest industrial area. The large volumes of port traffic and urban population in excess of 1 million makes Busan a Large-Port metropolis using the Southampton System of Port-City classification. As of 2025, Busan Port is the primary port in Korea and the world's sixth-largest container port.

Busan is divided into 15 major administrative districts and a single county, together housing a population of approximately 3.6 million. The full metropolitan area, the Southeastern Maritime Industrial Region, has a population of approximately 8 million. The most densely built-up areas of the city are situated in a number of narrow valleys between the Nakdong and the Suyeong Rivers, with mountains separating most of the districts. The Nakdong River is Korea's longest river and Busan's Haeundae Beach is also the country's largest.
