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.

“There are souls that are incurable and lost to the rest of society. Deprive them of one means of folly, they will invent ten thousand others. They will create subtler, wilder methods, methods that are absolutely DESPERATE. Nature herself is fundamentally antisocial, it is only by a usurpation of powers that the organized body of society opposes the natural inclination of humanity.”
—Antonin Artaud (1896–1948)
“Art, if one employs this term in the broad sense that includes poetry within its realm, is an art of creation laden with ideals, located at the very core of the life of a people, defining the spiritual and moral shape of that life.”
—Ivan Sergeevich Turgenev (1818–1883)
“We must be generously willing to leave for a time the narrow boundaries in which our individual lives are passed ... In this fresh, breezy atmosphere ... we will be surprised to find that many of our familiar old conventional truths look very queer indeed in some of the sudden side lights thrown upon them.”
—Bertha Honore Potter Palmer (1849–1918)
“Man will return to his origins. Goethe has finally become as squiggly as the city of his fathers.”
—Franz Grillparzer (1791–1872)
