Suburb in the context of "Lake Oswego"

A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries, commercial areas, transport network, infrastructure and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.

In the United States, metropolitan areas are delineated around the core of a core based statistical area, which is defined as an urban area and includes central and outlying counties. In other countries metropolitan areas are sometimes anchored by one central city such as the Paris metropolitan area (Paris). In other cases, metropolitan areas contain multiple centers of equal or close to equal importance, especially in the United States; for example, the Dallas–Fort Worth metropolitan area has eight principal cities. The Islamabad–Rawalpindi metropolitan area in Pakistan, the Rhine-Ruhr in Germany, and the Randstad in The Netherlands are other examples.

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.

Commuting is periodically recurring travel between a place of residence and place of work or study, where the traveler, referred to as a commuter, leaves the boundary of their home community. By extension, it can sometimes be any regular or often repeated travel between locations, even when not work-related. The modes of travel, time taken and distance traveled in commuting varies widely across the globe. Most people in least-developed countries continue to walk to work. The cheapest method of commuting after walking is usually by bicycle, so this is common in low-income countries but is also increasingly practised by people in wealthier countries for environmental, health, and often time reasons. In middle-income countries, motorcycle commuting is very common.

The next technology adopted as countries develop is more dependent on location: in more populous, older cities, especially in Eurasia mass transit (rail, bus, etc.) predominates, while in smaller, younger cities, and large parts of North America and Australasia, commuting by personal automobile is more common. A small number of very wealthy people, and those working in remote locations around the world, also commute by air travel, often for a week or more at a time rather than the more typical daily commute. Transportation links that enable commuting also impact the physical layout of cities and regions, allowing a distinction to arise between mostly-residential suburbs and the more economically focused urban core of a city (process known as suburban sprawl), but the specifics of how that distinction is realized remain drastically different between societies, with Eurasian "suburbs" often being more densely populated than North American "urban cores".

The term built environment refers to human-made conditions and is often used in architecture, landscape architecture, urban planning, public health, sociology, and anthropology, among others. These curated spaces provide the setting for human activity and were created to fulfill human desires and needs. The term can refer to a plethora of components including the traditionally associated buildings, cities, public infrastructure, transportation, open space, as well as more conceptual components like farmlands, dammed rivers, wildlife management, and even domesticated animals.

The built environment is made up of physical features. However, when studied, the built environment often highlights the connection between physical space and social consequences. It impacts the environment and how society physically maneuvers and functions, as well as less tangible aspects of society such as socioeconomic inequity and health. Various aspects of the built environment contribute to scholarship on housing and segregation, physical activity, food access, climate change, and environmental racism.

Urban planning (also called city planning or town planning in some contexts) is the process of developing and designing land use and the built environment, including air, water, and the infrastructure passing into and out of urban areas, such as transportation, communications, and distribution networks, and their accessibility. Traditionally, urban planning followed a top-down approach in master planning the physical layout of human settlements. The primary concern was the public welfare, which included considerations of efficiency, sanitation, protection and use of the environment, as well as taking account of effects of the master plans on the social and economic activities. Over time, urban planning has adopted a focus on the social and environmental "bottom lines" that focuses on using planning as a tool to improve the health and well-being of people and maintain sustainability standards. In the early 21st century, urban planning experts such as Jane Jacobs called on urban planners to take resident experiences and needs more into consideration.

Urban planning answers questions about how people will live, work, and play in a given area and thus, guides orderly development in urban, suburban and rural areas. Although predominantly concerned with the planning of settlements and communities, urban planners are also responsible for planning the efficient transportation of goods, resources, people, and waste; the distribution of basic necessities such as water and electricity; a sense of inclusion and opportunity for people of all kinds, culture and needs; economic growth or business development; improving health and conserving areas of natural environmental significance that actively contributes to reduction in CO₂ emissions as well as protecting heritage structures and built environments. Since most urban planning teams consist of highly educated individuals that work for city governments, recent debates focus on how to involve more community members in city planning processes.

Magoula (Greek: Μαγούλα) is a suburban town of Athens and former community (pop. 4,992 in 2011) of West Attica, located in the Thriasio Plain. Since the 2011 local government reform, it is part of the municipality Elefsina, of which it is a municipal unit. The municipal unit has an area of 18.134 km.

Magoula is located 2 km east of Mandra, 5 km north of Elefsina and 21 km northwest of central Athens. The municipal unit of Magoúla also includes the village of Néos Póntos. Magoula is served by a station on the Athens Airport–Patras railway. The A6 motorway runs southeast of the town.

An automotive city, also known as a car-centric city, is an urban area that facilitates and encourages the movement of people via private transportation, rather than public transport, cycling, or walking. This is achieved through both 'physical planning'—such as modifications to the built environment including street networks, parking spaces, automobile–pedestrian interface systems, and low-density urbanised areas with detached dwellings, driveways, or garages—and 'soft programming', such as social policy shaping street use through traffic safety and automobile campaigns, automobile laws, and the social redefinition of streets as public spaces primarily reserved for motor vehicles.

A neighbourhood (Commonwealth English) or neighborhood (American English) is a geographically localized community within a larger town, city, suburb or rural area, sometimes consisting of a single street and the buildings lining it. Neighbourhoods are often social communities with considerable face-to-face interaction among members. Researchers have not agreed on an exact definition, but the following may serve as a starting point: "Neighbourhood is generally defined spatially as a specific geographic area and functionally as a set of social networks. Neighbourhoods, then, are the spatial units in which face-to-face social interactions occur—the personal settings and situations where residents seek to realise common values, socialise youth, and maintain effective social control."

In urban planning, a historic core city or central city is the municipality with the largest 1940 population in the present metropolitan area (metropolitan statistical area). This term was retired by the US census bureau and replaced by the term principal city, which can include historic core cities and post-WWII cities. Metropolitan areas were no longer considered monocentric, but polycentric due to suburbanization of employment. A historic core city is not to be confused with the core of a metropolitan area which is defined as an urban area with a population of over 50,000 by the US census bureau.

Historic core cites in the United States often have higher detached single family housing rates, lower density, and fewer jobs than surrounding satellite cities and suburbs. A central city is usually the first settlement established in an urban region, years before the outlying districts came into existence. These cities typically contain less economic activity and more crime than their surrounding areas. Central cities often form the regional downtowns of metro areas. The term is used mainly in US context, although since the 1970s it has also become relatively common in Canada and, to a lesser extent, Europe and Australia.
