Common Methods For Defining The Boundaries of A City
- Urban Area
- "City" defined as a physically contiguous urban area, without regard to territorial or other boundaries. The delineation is usually done using some type of urban density, such as population density or density of buildings (for example, "gaps between structures may not exceed 200 metres"). Satellite and/or aerial maps may be used. For statistical convenience, such areas are sometimes adjusted to appropriate administrative boundaries, yielding an agglomeration.
- Metropolitan Area
- "City" as defined by the habits of its demographic population, as by metropolitan area, labour market area, or similar. Such definitions are usually based on commuting between home and work. Commuter flow thresholds into the core urban area are established by the national census authority, determining which areas are included.
- City Proper (Administrative)
- "City" as strictly defined by a given government (city proper). Typically based on a municipality or equivalent entity, or sometimes a group of municipalities under a regional government.

“The common behavior of mankind is the system of reference by means of which we interpret an unknown language.”
—Ludwig Wittgenstein (1889–1951)
“The philosopher is in advance of his age even in the outward form of his life. He is not fed, sheltered, clothed, warmed, like his contemporaries. How can a man be a philosopher and not maintain his vital heat by better methods than other men?”
—Henry David Thoreau (1817–1862)
“The industrial world would be a more peaceful place if workers were called in as collaborators in the process of establishing standards and defining shop practices, matters which surely affect their interests and well-being fully as much as they affect those of employers and consumers.”
—Mary Barnett Gilson (1877–?)
“Not too many years ago, a child’s experience was limited by how far he or she could ride a bicycle or by the physical boundaries that parents set. Today ... the real boundaries of a child’s life are set more by the number of available cable channels and videotapes, by the simulated reality of videogames, by the number of megabytes of memory in the home computer. Now kids can go anywhere, as long as they stay inside the electronic bubble.”
—Richard Louv (20th century)
“There was never a revolution to equal it, and never a city more glorious than Petrograd, and for all that period of my life I lived another and braved the ice of winter and the summer flies in Vyborg while across my adopted country of the past, winds of the revolution blew their flame, and all of us suffered hunger while we drank at the wine of equality.”
—Norman Mailer (b. 1923)
