Ambiguities in measuring the "size" of a city

The question of determining the world's largest cities does not allow a single, simple answer. It depends on which definitions of "city" and "size" are used, and how those definitions are applied. Complex political/cultural/social situations, sometimes controversial or disputed, further confuse the discussion. Debate on this field is highly vulnerable to bias or manipulation, as people^[who?] tend to prefer whichever definition most flatters their own city.

The "size" of a city can refer to either its land area or, more typically, its population.

The boundaries of a city can also be defined in any of several ways:

Morphological / Urban    ( Space, Density)

"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 aspopulation 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 anagglomeration.

Functional / Metropolitan  (People, Demographics)

"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 andwork. Commuter flow thresholds into the core urban area are established by the national censusauthority, determining which areas are included.

City Proper (Administrative, City Council)

"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.

Canada ( /ˈkænədə/) is a North American country consisting of ten provinces and three territories. Located in the northern part of the continent, it extends from the Atlantic Ocean in the east to the Pacific Ocean in the west and northward into the Arctic Ocean. It is the world's second largest country by total area. Canada's common border with the United States to the south and northwest is the longest in the world.


In 1867, with the union of three British North American colonies throughConfederation, Canada was formed as a federal dominion of four provinces. This began an accretion of provinces and territories and a process of increasing autonomy from the United Kingdom. This widening autonomy was highlighted by the Statute of Westminster 1931 and culminated in the Canada Act 1982, which severed the vestiges of legal dependence on the British parliament.


It is a member of the G7, G8, G20, NATO, OECD, WTO, Commonwealth of Nations,Francophonie, OAS, APEC, and UN. With the eighth-highest Human Development Index globally, it has one of the highest standards of living in the world.
