(the contiguous built-up area) with peripheral zones not themselves necessarily urban in character, but closely bound to the center by employment or commerce; these zones are also sometimes known as a commuter belt, and may extend well beyond the urban periphery depending on the definition used.

The core cities in a polycentric metropolitan area need not be physically connected by continuous built-up development, distinguishing the concept from conurbationConurbation A conurbation is an urban area comprising a number of cities, towns and villages which, through population growth and expans... , which requires urban contiguity. In a metropolitan area, it is sufficient that central cities together constitute a large population nucleus with which other constituent parts have a high degree of integration. In practice the parameters of metropolitan areas, in both official and unofficial usage, are not consistent. Sometimes they are little different from an urban area, and in other cases they cover broad regions that have little relation to the traditional concept of a city as a single urban settlement. Thus all metropolitan area figures should be treated as interpretations rather than as hard facts. Metro area population figures given by different sources for the same place can vary by millions, and there is a tendency for people to promote the highest figure available for their own "city". However the most ambitious metropolitan area population figures are often better seen as the population of a "metropolitan region" than of a "city".

Each capital city forms its own Statistical Division, and the population of the SD is the most-often quoted figure for that city's population. Statistical Districts are defined as non-capital but predominantly urban areas. The statistical divisions that encompass the capital cities are commonly though unofficially called 'metropolitan areas'.

Additional terms At the turn of the 19th century only 3 percent of the world was urbanized. During the 20th and into the 21st century the presence of humans in urban areas has increased dramatically. Within the first quarter of the 21st century it is expected that more than half of the world's population will live in urban areas, if this is not already the case.

If several metropolitan areas are located in succession, metropolitan areas are sometimes grouped together as a megalopolis (plural megalopoleis, also megalopolises). A megalopolis consists of several interconnected cities (and their suburbs), between which people commute, and which are so close together that suburbs can claim to be suburbs of more than one city.

A Canadian "megacity", however, is not necessarily an entirely urbanized area, as many cities so named have both rural and urban portions. It also doesn't need 10 million inhabitants to bear the designation. Moreover, Canadian "megacities" do not constitute large metropolitan areas in a global sense. Census population of a metro area is not the city population. However, it better demonstrates the population of the city.
