The most populated city proper is Shanghai A city is distinguished from other human settlements by its relatively great size, but also by its functions and its special symbolic status, which may be conferred by a central authority.The term can also refer either to the physical streets and buildings of the city or to the collection of people who dwell there, and can be used in a general sense to mean urban rather than rural territory.A variety of definitions, invoking population, population density, number of dwellings, economic function, and infrastructure, are used in national censuses to classify populations as urban.Common population definitions for a city range between 1,500 and 50,000 people, with most states using a minimum between 1,5 inhabitants.The Indus Valley Civilisation built Mohenjo-Daro, Harappa and other cities on a grid pattern, using ancient principles described by Kautilya, and aligned with the compass points.The ancient Greek city of Priene exemplifies a grid plan with specialized districts used across the Hellenistic Mediterranean.

Urban structure generally follows one or more basic patterns: geomorphic, radial, concentric, rectilinear, and curvilinear.In others, such as in the United Kingdom, city status is awarded on local criteria.According to the "functional definition" a city is not distinguished by size alone, but also by the role it plays within a larger political context.Cities serve as administrative, commercial, religious, and cultural hubs for their larger surrounding areas.A typical city has professional administrators, regulations, and some form of taxation (food and other necessities or means to trade for them) to feed the government workers.
