Urbanism is the study of the characteristic ways of interaction of inhabitants of towns and cities (urban areas) with the built environment. It is a direct component of disciplines such as urban planning (the physical design and management of urban structures) and urban sociology (the study of urban life and culture). However, in some contexts internationally Urbanism is synonymous with Urban Planning, and the Urbanist refers to a Urban Planner.
Many architects, planners, and sociologists investigate the way people live in densely populated urban areas. There is a huge variety of approaches within urbanism.
Urbanism's emergence in the early 20th century was associated with the rise of centralized manufacturing, mixed-use neighborhoods, social organizations and networks, and what has been described as "the convergence between political, social and economic citizenship".
Urbanism can be understood as placemaking and the creation of place identity at a city-wide level, however as early as 1938 Louis Wirth wrote that it is necessary to stop 'identify[ing] urbanism with the physical entity of the city', go 'beyond an arbitrary boundary line' and consider how 'technological developments in transportation and communication have enormously extended the urban mode of living beyond the confines of the city itself.'
