MetropolisA metropolis () is a large city or conurbation which is a significant economic, political, and cultural center for a country or region, and an important hub for regional or international connections, commerce, and communications. The term is Ancient Greek (μητρόπολις) and means the "mother city" of a colony (in the ancient sense), that is, the city which sent out settlers. This was later generalized to a city regarded as a center of a specified activity, or any large, important city in a nation.
A big city belonging to a larger urban agglomeration, but which is not the core of that agglomeration, is not generally considered a metropolis but a part of it. The plural of the word is metropolises, although the Latin plural is metropoles, from the Greek metropoleis (μητρoπόλεις).
For urban centers outside metropolitan areas that generate a similar attraction at smaller scale for their region, the concept of the regiopolis ("regio" for short) was introduced by German academics in 2006.
In the ancient world, a metropolis was the city or state of origin of a colony.
Etymology and modern usageMetropolis (μητρόπολις) is a Greek word, coming from μήτηρ, mḗtēr meaning "mother" and πόλις, pólis meaning "city" or "town", which is how the Greek colonies of antiquity referred to their original cities, with whom they retained cultic and political-cultural connections. The word was used in post-classical Latin for the chief city of a province, the seat of the government and, in particular, ecclesiastically for the seat or see of a metropolitan bishop to whom suffragan bishops were responsible. This usage equates the province with the diocese or episcopal see.
Global cityThe concept of a global city (or world city) is of a city that has a direct and tangible effect on global affairs through socioeconomic means. The term has become increasingly familiar, because of the rise of globalization (i.e., global finance, communications, and travel). An attempt to define and categorize world cities by financial criteria was made by the Globalization and World Cities Research Network (GaWC), based primarily at Loughborough University in England. The study ranked cities based on their provision of "advanced producer services" such as accountancy, advertising, finance and law. The inventory identifies three levels of world cities and several sub-ranks (see GaWC study).
A metropolis is not necessarily a global city—or, being one, it might not be among the top-ranking—due to its standards of living, development, and infrastructure. A metropolis that is also a global city is a global metropolis.
