Chongqing vs Greater Sudbury

Informations

Chongqing (Sichuanese pronunciation: [tsʰoŋ˨˩tɕʰin˨˩˦], Standard Mandarin pronunciation: [ʈʂʰʊ̌ŋ.tɕʰîŋ] (listen), UK: , US: ,), alternately romanized as Chungking, is a megacity in southwest China. Administratively, it is one of the four municipalities under the direct administration of central government of the People's Republic of China (the other three are Beijing, Shanghai and Tianjin), and the only such municipality located far away from the coast. The municipality of Chongqing, which is around the size of Austria, includes the city of Chongqing and various non-connected cities. As the Chongqing municipality government directly administers the city of Chongqing, as well as rural counties, and other cities not connected to the city of Chongqing, Chongqing municipality can technically claim to be the largest city proper in the world, even though this is due to a classification technicality and not because it is actually the world's largest urban area. This title belongs to the Guangzhou-Shenzhen Pearl River Delta agglomeration. Chongqing was a municipality during the Republic of China (ROC) administration, within the Sichuan Province. It served as its wartime capital during the Second Sino-Japanese War (1937–1945), being one of the world's anti-fascist command centers. The current municipality was separated from Sichuan province on 14 March 1997 to help develop the central and western parts of China.

The Chongqing administrative municipality has a population of over 30 million. The city of Chongqing, comprising 9 urban and suburban districts, has a population of 8,750,000 as of 2018. According to the 2010 census, Chongqing is the most populous Chinese municipality, and also the largest direct-controlled municipality in China, containing 26 districts, eight counties, and four autonomous counties. The official abbreviation of the city, "Yú" (渝), was approved by the State Council on 18 April 1997. This abbreviation is derived from the old name of a part of the Jialing River that runs through Chongqing and feeds into the Yangtze River. Chongqing has a significant history and culture. Being one of China's National Central Cities, it serves as the economic centre of the Sichuan Basin and the upstream Yangtze. It is a major manufacturing centre and transportation hub; a July 2012 report by the Economist Intelligence Unit described it as one of China's "13 emerging megalopolises". Chongqing is ranked as a Beta global city. Chongqing is also one of the top 100 science cities in the world by scientific research as tracked by the Nature Index according to the Nature Index 2020 Science Cities and home to several notable universities, including Chongqing University and Southwest University.

Sudbury, officially Greater Sudbury (French: Grand-Sudbury), is a city in Ontario, Canada. It is the largest city in Northern Ontario by population, with a population of 161,531 at the 2016 Canadian Census. By land area, it is the largest in Ontario and the fifth largest in Canada. It is administratively a Unitary authority, and thus not part of any district, county, or regional municipality. The City of Greater Sudbury is separate from but entirely surrounded by Sudbury District. The Sudbury region was inhabited by the Ojibwe people of the Algonquin group for thousands of years prior to the founding of Sudbury following the discovery of nickel ore in 1883 during the construction of the transcontinental railway. Greater Sudbury was formed in 2001 by merging the cities and towns of the former Regional Municipality of Sudbury with several previously unincorporated townships. Being located inland, the local climate is extremely seasonal with average January lows of around −18 °C (0 °F) and average July highs of 25 °C (77 °F).

The population resides in an urban core and many smaller communities scattered around 330 lakes and among hills of rock blackened by historical smelting activity. Sudbury was once a major lumber centre and a world leader in nickel mining. Mining and related industries dominated the economy for much of the 20th century. The two major mining companies which shaped the history of Sudbury were Inco, now Vale Limited, which employed more than 25% of the population by the 1970s, and Falconbridge, now Glencore. Sudbury has since expanded from its resource-based economy to emerge as the major retail, economic, health and educational centre for Northeastern Ontario. Sudbury is also home to a large Franco-Ontarian population that influences its arts and culture.
