of world cities
A conurbation is a region comprising a number of cities, large towns, and other urban areas that, through population growth and physical expansion, have merged to form one continuous urban and industrially developed area. In most cases, a conurbation is a polycentric urban agglomeration, in which transportation has developed to link areas to create a single urban labour market or travel to work area.
The term "conurbation" was coined in 1915 by Patrick Geddes in his book Cities In Evolution. He drew attention to the ability of the (then) new technology of electric power and motorised transport to allow cities to spread and agglomerate together, and gave as examples "Midlandton" in England, the Ruhr in Germany, Randstad in the Netherlands, New York City–North Jersey in the United States, the Greater Tokyo Area, Taiheiyō Belt in Japan, NCR of Delhi in India, and Southern Metro Manila in the Philippines.
The term is described in Britain, whereas the term is described in the United States to most closely be a metropolitan area by the Census Bureau. It may consist of a central city and its suburbs. A conurbation consists of adjacent metropolitan areas that are connected with one another by urbanization[clarification needed] Internationally, the term "urban agglomeration" is often used to convey a similar meaning to "conurbation".[clarification needed] A conurbation should also be contrasted with a megalopolis, where the urban areas are close but not physically contiguous and where the merging of labour markets has not yet developed.

- Important Notes: This lists UK urban areas only and excludes UK conurbations by definition of the term for example the Liverpool Manchester or the Manchester Liverpool conurbation  is defined as one conurbation by AESOP in a comparison report published by the University of Manchester in 2005 found here:Liverpool Manchester Conurbation has a population of 5.68 millon.
Industrial and housing growth in the United Kingdom during the 19th and early 20th centuries produced many conurbations. Greater London is by far the largest urban area and is usually counted as a conurbation in statistical terms, but differs from the others in the degree to which it is focused on a single central area. In the mid-1950s the Green Belt was introduced to stem the further urbanisation of the countryside in England. Note that as used in the United Kingdom, the term "conurbation" is closer to the meaning of urban agglomeration.
The list below shows the most populous urban areas in the UK as defined by the Office for National Statistics (ONS). The Greater London Urban Area contains the whole of what is commonly called London, but ONS definitions divide London into a large number of smaller localities of which the largest is Croydon.
Golden Horseshoe (Ontario)
The "Golden Horseshoe" is a densely populated and industrialized region centred on the west end of Lake Ontario in Southern Ontario, Canada. Most of it is also part of the Windsor-Quebec City corridor. With a population of 8.8 million people, the Golden Horseshoe makes up slightly over a quarter (25.6%) of the population of Canada and contains approximately 75% of Ontario's population, making it one of the largest population concentrations in North America. Although it is a geographically named sub-region of Southern Ontario, "Greater Golden Horseshoe" is more frequently used today to describe the metropolitan regions that stretch across the area in totality. The largest cities in the region include Toronto, Mississauga, Oakville, Burlington, St. Catherines, Brampton, and Hamilton.
Greater Montreal (Quebec)
Greater Montreal is Canada's 2nd largest conurbation, with Statistics Canada defining the Census Metropolitan Area (CMA) as 4,258.31 square kilometres (1,644.14 sq mi) and a population of 3,824,221 as of 2011, which represents almost half of the population of the province of Quebec. Slightly smaller, there are 82 municipalities grouped under the Montreal Metropolitan Community to coordinate issues such as land planning, transportation, and economic development.
Lower Mainland (British Columbia)
British Columbia's Lower Mainland is the most populated area in Western Canada. It consists of many mid-sized continuous urban areas, including Vancouver, North Vancouver (city and district municipality), Surrey, Burnaby, Richmond, and Coquitlam. The Lower Mainland population is around 2.5 million as of 2011 and the area is among the highest growth rates in the continent up 9.2 percent from the 2006 census.
National Capital Region (Ontario and Quebec)
The National Capital Region (NCR) is made up of the capital, Ottawa, and neighbouring Gatineau which is located across the Ottawa River. As Ottawa is in Ontario and Gatineau, Quebec, this is a unique conurbation. Federal government buildings are located in both cities and many workers live in one city and work in the other. The National Capital Region consists of an area of 5,319 square kilometres that straddles the boundary between the provinces of Ontario and Quebec. The area of the National Capital Region is very similar to that of the Ottawa-Gatineau Census Metropolitan Area (CMA), although the National Capital Region contains a number of small neighbouring communities that are not contained within the CMA. When all the communities are added, the population is around 1,500,000. Ottawa-Gatineau is the only CMA in the nation to fall within two provinces.
New York Tri-State Area
One example of a conurbation is the expansive concept of the New York metropolitan area (the Tri-State Region) centered on New York City, including 30 counties spread between New York State, New Jersey, Connecticut, and Pennsylvania, with an estimated population of 21,961,994 in 2007. Approximately one-fifteenth of all U.S. residents live in the Greater New York City area. This conurbation is the result of several central cities whose urban areas have merged.
Greater Boston Area
Holding a population of 7,427,336 as of 2005, the Combined Statistical Area including Greater Boston consists of Boston proper and a collection of distinct but intertwined cities including Providence, Rhode Island, Worcester, Massachusetts, and Manchester, New Hampshire. Most importantly, the cities that comprise the Greater Boston CSA are interlinked by heavy public transportation infrastructure, maintain continuously urban interstices, and hold mutual commuting patterns.
San Francisco Bay Area
Greater Los Angeles Area
The Greater Los Angeles Area consists of the merging of several distinct central cities and counties, including Los Angeles, Orange County, Riverside, and San Bernardino. This area is also often referred to simply as Southern California or colloquially as SoCal (a larger region which tends to include San Diego).
The traditionally separate metropolitan areas of Baltimore and Washington, D.C. have shared suburbs and a continuous urbanization between the two central cities (Baltimore–Washington metropolitan area).
Three large cities, Dallas, Fort Worth, and Arlington, make up this area. Each city is linked by touching city limits or suburbs. This area is also commonly known as the Metroplex and is included in the emerging megalopolis known as the Texas Triangle.
The major U.S. city of Detroit, Michigan lies immediately across the Detroit River from Windsor, Ontario in Canada. In many respects—economically, historically, culturally, socially, and, of course, geographically—Windsor is more a part of Metro Detroit than of Ontario. The two cities and their surrounding suburbs are commonly referred to collectively as the Detroit–Windsor area. The Detroit-Windsor border is the largest commercial border crossing in North America and the busiest between the two countries. With a combined total population of nearly six million, Detroit-Windsor is the world's largest trans-border metropolitan area (since Hong Kong was returned to China.)
The entire tri-county area also known as the Miami-Fort Lauderdale-West Palm Beach metropolitan area is now continuously urbanized along a roughly 100 miles (161 km) length of the Florida east coast as well as extending inland and continuing south of Miami as far as Florida City. Although this is generally all referred to as a single metropolitan area, not a conurbation, it is sometimes broken up into the Miami, Fort Lauderdale, and West Palm Beach metros.
St. Paul – Minneapolis
Minneapolis–Saint Paul is the most populous urban area in the state of Minnesota, and is composed of 182 cities and townships built around the Mississippi, Minnesota, and St. Croix rivers. The area is also nicknamed the Twin Cities for its two largest cities, Minneapolis, with the highest population, and Saint Paul, the state capital.
Brisbane, Gold Coast, and Sunshine Coast are currently merged to form a region known as South East Queensland (SEQ) that comprises a population of 3.05 million people.
