Metropolitan area in the context of "Port Said"

This is a list of urban areas in the European Union with over 500,000 inhabitants as of 2022. The data comes from Demographia and the United Nations Department of Economic and Social Affairs. Demographia provides figures for urban areas (including conurbations), while the UN DESA figures are a mix agglomerations, cities proper and metropolitan areas. For comparison, Function Urban Area (FUA) population figures by Eurostat are also provided, however, these measure the wider metropolitan areas.

The United Nations uses three definitions for what constitutes a city, as not all cities in all jurisdictions are classified using the same criteria. Cities may be defined as the cities proper, their metropolitan regions, or the extent of their urban area. A complicating factor is that many large cities in the world have not only homeless or the unhoused, but also vast slum communities. This leads to official census data being less accurate in representing the actual number of residents in a given area.

A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower boundary for their size. In a narrower sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.

Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities usually form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling toward city centres for employment, entertainment, and education. However, in a world of intensifying globalization, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues, such as sustainable development, climate change, and global health. Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11. Due to the efficiency of transportation and the smaller land consumption, dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant harmful effects, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.

The functional urban area (FUA), previously known as larger urban zone (LUZ), is a measure of the population and expanse of metropolitan and surrounding areas which may or may not be exclusively urban. It consists of a city and its commuting zone, which is a contiguous area of spatial units that have at least 15% of their employed residents working in the city.

The FUA represents an attempt at a harmonised definition of the metropolitan area. Eurostat's objective was to have an area from which a significant share of the residents commute into the city, a concept known as the "functional urban region." To ensure a good data availability, Eurostat adjusts the FUA boundaries to administrative boundaries that approximate the functional urban area.

Marseille (French: Marseille; Provençal Occitan: Marselha; see below) is a city in southern France, the prefecture of the department of Bouches-du-Rhône and of the Provence-Alpes-Côte d'Azur region. Situated in the Provence region, it is located on the coast of the Mediterranean Sea, near the mouth of the Rhône river. Marseille is the second-most populous city in France, after Paris, with 877,215 inhabitants in 2022 (Jan. census) over a municipal territory of 241 km (93 sq mi). Together with its suburbs and exurbs, the Marseille metropolitan area, which extends over 3,972 km (1,534 sq mi), had a population of 1,900,957 at the Jan. 2022 census. The cities of Marseille, Aix-en-Provence, and 90 suburban municipalities have formed since 2016 the Aix-Marseille-Provence Metropolis, an indirectly elected metropolitan authority now in charge of wider metropolitan issues, with a population of 1,922,626 at the Jan. 2022 census.

Founded c. 600 BC by Greek settlers from Phocaea, Marseille is the oldest city in France, as well as one of Europe's oldest continuously inhabited settlements. It was known to the ancient Greeks as Massalia and to Romans as Massilia. Marseille has been a trading port since ancient times. In particular, it experienced a considerable commercial boom during the colonial period and especially during the 19th century, becoming a prosperous industrial and trading city. Nowadays the Old Port still lies at the heart of the city, where the manufacture of Marseille soap began some six centuries ago. Overlooking the port is the Basilica of Notre-Dame-de-la-Garde or "Bonne-mère" for the people of Marseille, a Romano-Byzantine church and the symbol of the city. Inherited from this past, the Grand Port Maritime de Marseille (GPMM) and the maritime economy are major poles of regional and national activity and Marseille remains the first French port, the second Mediterranean port and the fifth European port. Since its origins, Marseille's openness to the Mediterranean Sea has made it a cosmopolitan city marked by cultural and economic exchanges with Southern Europe, the Middle East, North Africa and Asia. In Europe, the city has the third largest Jewish community after London and Paris.

A city proper is the geographical area contained within city limits. The term proper is not exclusive to cities; it can describe the geographical area within the boundaries of any given locality. The United Nations defines the term as "... the single political jurisdiction which contains the historical city centre."

City proper is one of the three basic concepts used to define urban areas and populations. The other two are urban agglomeration, and the metropolitan area. In some countries, city limits that act as the demarcation for the city proper are drawn very wide, in some very narrow. This can be cause for recurring controversy.

The Greater Tokyo Area is the most populous metropolitan area in the world, consisting of the Kantō region of Japan (including Tokyo Metropolis and the prefectures of Chiba, Gunma, Ibaraki, Kanagawa, Saitama, and Tochigi) as well as the prefecture of Yamanashi of the neighboring Chūbu region. In Japanese, it is referred to by various terms, one of the most common being Capital Region (首都圏, Shuto-ken).

As of 2016, the United Nations estimates the total population at 38,140,000. It covers an area of approximately 13,500 km (5,200 mi), giving it a population density of 2,642 people/km. It is the second-largest single metropolitan area in the world in terms of built-up or urban function landmass at 8,547 km (3,300 mi), behind only the New York City metropolitan area at 11,642 km (4,495 mi). With over US$2 trillion in GDP, Tokyo remains the second-largest metropolitan economy in the world, also behind New York.

Greater São Paulo (Portuguese: Grande São Paulo) is a nonspecific term for one of the multiple definitions of the large metropolitan area located in the São Paulo state in Brazil.

The Warsaw metropolitan area (known in Polish as: aglomeracja warszawska or Miejski Obszar Funkcjonalny Warszawy) is the metropolitan area of Warsaw, the capital of Poland. The metropolitan area covers ten counties in the Masovian Voivodeship, with an area of 6,100 km (2,400 sq mi) and a population of around 3.5 million in 2022. The area constitutes a separate NUTS 2 unit, as well as a separate police region with a dedicated Capital Metropolitan Police Headquarters, both of them carved out from the Masovian Voivodeship as an exception, as Polish NUTS 2 areas and police regions are in general identical to the territories of voivodeships.

The largest cities or towns within the metropolitan area are Warsaw, Pruszków, Legionowo, Otwock, Mińsk Mazowiecki, Piaseczno and Wołomin.
