A megacity is a very large city, typically with a population of more than 10 million people. The United Nations Department of Economic and Social Affairs in its 2018 "World Urbanization Prospects" report defines megacities as urban agglomerations with over 10 million inhabitants. A University of Bonn report holds that they are "usually defined as metropolitan areas with a total population of 10 million or more people". Elsewhere in other sources, from five to eight million is considered the minimum threshold, along with a population density of at least 2,000 per square kilometre. The terms conurbation, metropolis, and metroplex are also applied to the latter.
Asturias officially the Principality of Asturias, is an autonomous community in northwest Spain.
A metropolitan area or metro is a region consisting of a densely populated urban agglomeration and its surrounding territories which share industries, commercial areas, transport network, infrastructures and housing. A metropolitan area usually comprises multiple principal cities, jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts and even states and nations in areas like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.

Greater Glasgow is an urban settlement in Scotland consisting of all localities which are physically attached to the city of Glasgow, forming with it a single contiguous urban area. It does not relate to municipal government boundaries, and its territorial extent is defined by National Records of Scotland, which determines settlements in Scotland for census and statistical purposes. Greater Glasgow had a population of 1,199,629 at the time of the 2001 UK Census making it the largest urban area in Scotland and the fifth-largest in the United Kingdom. However, the population estimate for the Greater Glasgow 'settlement' in mid-2016 was 985,290—the reduced figure explained by the removal of the Motherwell & Wishaw (124,790), Coatbridge & Airdrie (91,020), and Hamilton (83,730) settlement areas east of the city due to small gaps between the populated postcodes. The 'new towns' of Cumbernauld and East Kilbride (75,120) were never included in these figures despite their close ties to Glasgow due to having a clear geographical separation from the city. In the 2020 figures, the Greater Glasgow population had risen to just over 1 million.
