Cities in the context of "Administrative divisions of Romania"

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.

Urbanism is the study of how inhabitants of urban areas, such as towns and cities, interact with the built environment. It is a direct component of disciplines such as urban planning, a profession focusing on the design and management of urban areas, and urban sociology, an academic field which studies urban life.

Many architects, planners, geographers, and sociologists investigate the way people live in densely populated urban areas. There is a wide variety of different theories and approaches to the study of urbanism. However, in some contexts internationally, urbanism is synonymous with urban planning, and urbanist refers to an urban planner.

A complex system is a system composed of many components that interact with one another. Examples of complex systems are Earth's global climate, organisms, the human brain, infrastructure such as power grid, transportation or communication systems, complex software and electronic systems, social and economic organizations (like cities), an ecosystem, a living cell, and, ultimately, for some authors, the entire universe.

The behavior of a complex system is intrinsically difficult to model due to the dependencies, competitions, relationships, and other types of interactions between their parts or between a given system and its environment. Systems that are "complex" have distinct properties that arise from these relationships, such as nonlinearity, emergence, spontaneous order, adaptation, and feedback loops, among others. Because such systems appear in a wide variety of fields, the commonalities among them have become the topic of their independent area of research. In many cases, it is useful to represent such a system as a network where the nodes represent the components and links represent their interactions.

An urban park or metropolitan park, also known as a city park, municipal park (North America), public park, public open space, or municipal gardens (UK), is a park or botanical garden in cities, densely populated suburbia and other incorporated places that offers green space and places for recreation to residents and visitors. Urban parks are generally landscaped by design, instead of lands left in their natural state. The design, operation and maintenance is usually done by government agencies, typically on the local level, but may occasionally be contracted out to a park conservancy, "friends of" group, or private sector company.

Depending on size, budget, and land features, which varies considerably among individual parks, common features include playgrounds, gardens, hiking, running, fitness trails or paths, bridle paths, sports fields and courts, public restrooms, boat ramps, performance venues, or BBQ and picnic facilities. Park advocates claim that having parks near urban residents, including within a 10-minute walk, provides multiple benefits.

This is a list of cities and towns in North Macedonia. There are 34 cities and towns in North Macedonia. In Macedonian, every city or town, regardless of size, is called grad (град, pl. gradovi, градови), but a smaller one can also be called gratče (гратче, pl. гратчиња, gratčinja), a diminutive of grad. Only five cities in the country have a population of more than 50,000 inhabitants. The capital, Skopje, and its metropolitan area are home to about 33% of the country's total population. The 2002 census showed that the majority of the population, 59.5%, lived in urban areas.

The five largest cities in North Macedonia, each with a population of over 50,000 inhabitants, are: Skopje (526,502), Kumanovo (75,051), Bitola (69,287), Prilep (63,308) and Tetovo (63,176).

The urbanization of the United States has progressed throughout its entire history. Over the last two centuries, the United States of America has been transformed from a predominantly rural, agricultural nation into an urbanized, industrial one. This was largely due to the Industrial Revolution in the United States (and parts of Western Europe) in the late 18th and early 19th centuries and the rapid industrialization which the United States experienced as a result. In 1790, only about one out of every twenty Americans (on average) lived in urban areas (cities), but this ratio had dramatically changed to one out of four by 1870, one out of two by 1920, two out of three in the 1960s, and four out of five in the 2000s.
