Megacity in the context of Colombia

New York, often called New York City (NYC), is the most populous city in the United States. It is located at the southern tip of New York State on New York Harbor, one of the world's largest natural harbors. The city comprises five boroughs, each coextensive with its respective county. It is the geographical and demographic center of both the Northeast megalopolis and the New York metropolitan area, the largest metropolitan area in the United States by both population and urban area. New York is a global center of finance and commerce, culture, technology, entertainment and media, academics and scientific output, the arts and fashion, and, as home to the headquarters of the United Nations, international diplomacy.

With an estimated population in July 2024 of 8,478,072, distributed over 300.46 square miles (778.2 km), the city is the most densely populated major city in the United States. New York City has more than double the population of Los Angeles, the country's second-most populous city. Over 20.1 million people live in New York City's metropolitan statistical area and 23.5 million in its combined statistical area as of 2020, both the largest in the U.S. New York City is one of the world's most populous megacities. The city and its metropolitan area are the premier gateway for legal immigration to the United States. An estimated 800 languages are spoken in New York City, making it the most linguistically diverse city in the world. The New York City metropolitan region is home to the largest foreign-born population of any metropolitan region in the world, approximately 5.9 million as of 2023.

The Dallas–Fort Worth metroplex, officially designated Dallas–Fort Worth–Arlington by the U.S. Office of Management and Budget, is the most populous metropolitan statistical area in the U.S. state of Texas and the Southern U.S., encompassing 11 counties. Its historically dominant core cities are Dallas and Fort Worth. It is the economic and cultural hub of North Texas. Residents of the area also refer to it as DFW (the code for Dallas Fort Worth International Airport) or the Metroplex. The Dallas–Fort Worth–Arlington metropolitan statistical area's population was 7,637,387 according to the U.S. Census Bureau's 2020 census, making it the fourth-largest metropolitan area in the U.S. and the eleventh-largest in the Americas. In 2016, the Dallas–Fort Worth metroplex had the highest annual population growth in the United States. By 2023, the U.S. Census Bureau estimated that the Dallas-Fort Worth metropolitan area's population had increased to 8,100,037, with the highest numerical growth of any metropolitan area in the United States. By 2025, NCTCOG estimated that the Dallas-Fort Worth metropolitan area's population had increased to around 8,578,654 million residents, making the Dallas-Fort Worth metropolitan area around 1.42 million residents from becoming a megacity.

The metropolitan region's economy, also referred to as Silicon Prairie, is primarily based on banking, commerce, insurance, telecommunications, technology, energy, healthcare, medical research, transportation, manufacturing, and logistics. As of 2022, Dallas–Fort Worth is home to 23 Fortune 500 companies, the 4th-largest concentration of Fortune 500 companies in the United States behind New York City (62), Chicago (35), and Houston (24). In 2016, the metropolitan economy surpassed Houston, the second largest metro area in Texas, to become the fourth-largest in the U.S. The Dallas–Fort Worth metroplex boasted a GDP of just over $620.6 billion in 2020 (although both metropolitan regions have switched places multiple times since GDP began recording). If the Metroplex were a sovereign state, it would have the twentieth largest economy in the world as of 2019. In 2015, the conurbated metropolitan area would rank the ninth-largest economy if it were a U.S. state. In 2020, Dallas–Fort Worth was recognized as the 36th best metropolitan area for STEM professionals in the U.S.

This is a list showing the most populous cities in Pakistan as of the 2023 Census of Pakistan. City populations found in this list only refer to the population found within the city's defined limits and any adjacent cantonment, if exists (except for Gujranwala and Okara). The census totals below come from the Pakistan Bureau of Statistics for the four provinces of Pakistan and the Islamabad Capital Territory, and from the Planning and Development Department of Azad Jammu Kashmir (PND AJK) for cities of Azad Kashmir.

As of the 2023 Pakistani census, there are two megacities, ten million-plus cities, in Pakistan. Overall 127 cities of the country, have a population of over 100,000. Of these 127 cities, 81 are located in the country's most populous province, Punjab, 22 in Sindh, 13 in Khyber Pakhtunkhwa, 8 in Balochistan, two in Azad Kashmir, and one is the Islamabad Capital Territory itself. It is unknown whether Gilgit-Baltistan has any city with over 100,000 people or not, as 2017 census results issued by the Government of Gilgit–Baltistan do not give figures for the population of cities in Gilgit–Baltistan. As in the previous census in 1998, the largest city of Gilgit-Baltistan was Gilgit, with 56,701 inhabitants.

A secondary city is an urban hub that fills specific regional and local needs related to governance, economics, finance, education, trade, transportation. A secondary city is defined by population, area, function, and economic status, but also by their relationship to neighboring and distant cities and their socio-economic status. A secondary city may emerge from a cluster of smaller cities in a metropolitan region or may be the capital city of a province, state, or second-tier administrative unit within a country. Secondary cities are the fastest-growing urban areas in lower- and middle-income countries, experiencing unplanned growth and development. By 2030, there will be twice as many medium-size cities as there were in 1990, outnumbering the total number of megacities. According to the World Bank, secondary cities make up almost 40% of the world cities population. Many secondary cities in the Global South are expected to undergo massive expansions in the next few decades comparable to city growth in Europe and North America over the past two centuries. These cities are unique environments that generally have limited data and information on infrastructure, land tenure, and planning.

Greater Los Angeles is the most populous metropolitan area in the U.S. state of California, encompassing five counties in Southern California extending from Ventura County in the west to San Bernardino County and Riverside County in the east, with the city of Los Angeles and Los Angeles County at its center, and Orange County to the southeast. The Los Angeles–Long Beach combined statistical area (CSA) covers 33,954 square miles (87,940 km), making it the largest metropolitan region in the United States by land area. The contiguous urban area is 2,281 square miles (5,910 km), whereas the remainder mostly consists of mountain and desert areas. With an estimated population of over 18.3 million (U.S. Census Bureau, 2023), it is the second-largest metropolitan area in the country, behind New York, as well as one of the largest megacities in the world.

In addition to being the nexus of the global entertainment industry, including films, television, and recorded music, Greater Los Angeles is also an important center of international trade, education, media, business, tourism, technology, and sports. It is the third-largest metropolitan area by nominal GDP in the world with an economy exceeding $1 trillion in output, behind New York City and Tokyo.

New Delhi is the capital of India and a part of the National Capital Territory of Delhi (NCT). New Delhi is the seat of all three branches of the Government of India, hosting the Rashtrapati Bhavan (Presidential Palace), Sansad Bhavan (Parliament House), and the Supreme Court. New Delhi is a municipality within the NCT, administered by the New Delhi Municipal Council (NDMC), which covers mostly Lutyens' Delhi and a few adjacent areas. The municipal area is part of a larger administrative district, the New Delhi district.

Although colloquially Delhi and New Delhi are used interchangeably to refer to the National Capital Territory of Delhi, both are distinct entities, with the municipality and the New Delhi district forming a relatively small part within the megacity of Delhi. The National Capital Region is an even larger entity, comprising the entire NCT along with adjoining districts in the two neighbouring states forming a continuously built-up area with it, including Ghaziabad, Noida, Greater Noida, Meerut, YEIDA City, Gurgaon, and Faridabad.

As of 2023, the five largest cities in China by population are Chongqing (31.91 million), Shanghai (24.87 million), Beijing (21.86 million), Chengdu (21.403 million) and Guangzhou (18.827 million). As of 2024, there are 18 megacities (cities with a population of over 10 million), including Chongqing, Shanghai, Beijing, Chengdu, Guangzhou, Shenzhen, Wuhan, Tianjin, Xi'an, Suzhou, Zhengzhou, Hangzhou, Shijiazhuang, Linyi, Dongguan, Qingdao, Changsha and Hefei.

Among them, the total permanent population of Chongqing, Shanghai, Beijing and Chengdu is above 20 million. Shanghai is China's most populous urban area, while Chongqing is its largest city proper, the only city in China with the largest permanent population of over 30 million.

Lagos (/ˈleɪɡɒs/ LAY-goss; Yoruba: Èkó [èkó]), or Lagos City, is a large metropolitan city in southwestern Nigeria. As of November 2025, the size of the city's population has been estimated to stand between 17 and 21 million residents, making Lagos the largest city in Nigeria, the most populous urban area on the African continent, and one of the fastest-growing megacities in the world. Lagos was the national capital of Nigeria until the government's December 1991 decision to relocate its capital to Abuja, in the centre of the country. Apart from serving as a major African financial center, Lagos has also played a significant role in the national economy, serving as the economic hub of Lagos State and the entire country of Nigeria. The city has a significant influence on commerce, entertainment, technology, education, politics, tourism, art, and fashion in Africa. Lagos is also among the top ten of the world's fastest-growing cities and urban areas. A megacity, it has the second-highest GDP in Africa, and houses one of the largest and busiest seaports on the continent. Due to the large urban population and port traffic volumes, Lagos is classified as a Medium-Port Megacity.

Lagos emerged as a home to the Awori people, an Ijebu subgroup of the Yoruba of West Africa, in the 15th century, which is contained across the present-day Local Government Areas (LGAs) of Lagos Island, Eti-Osa, Amuwo-Odofin, and Apapa. Before the 15th century, the Awori settled on a farmstead along the coastal line, in and around which they worked and lived. Farmstead translates to Ereko in Yoruba, from which comes the Lagos indigenous name Eko. The lands are separated by creeks, fringing the southwest mouth of Lagos Lagoon, while being protected from the Atlantic Ocean by barrier islands and long sand spits such as Bar Beach, which stretch up to 100 km (62 mi) east and west of the mouth. Due to rapid urbanisation, the city expanded to the west of the lagoon to include areas in the present-day Lagos Mainland, Ajeromi-Ifelodun, and Surulere. This led to the classification of Lagos into two main areas: the Island, which was the original city of Lagos, and the Mainland, which it has since expanded into. This city area was governed directly by the Federal Government through the Lagos City Council until the creation of Lagos State in 1967, which led to the splitting of Lagos city into the present-day seven Local Government Areas (LGAs), and the addition of other towns (which now make up 13 LGAs) from the then Western Region to form the state.

The Pearl River Delta Metropolitan Region is the low-lying area surrounding the Pearl River estuary, where the Pearl River flows into the South China Sea. Referred to as the Guangdong–Hong Kong–Macao Greater Bay Area in official documents, the region is one of the most densely populated and urbanized regions in the world, and is considered a megacity by numerous scholars. It is currently the wealthiest region in Southern China and one of the wealthiest regions in China along with the Yangtze River Delta in Eastern China and Jingjinji in Northern China. Most of the region is part of the Pearl River Delta Economic Zone, which is a special economic zone of China.

The region is a megalopolis, and is at the southern end of a larger megalopolis running along the southern coast of China, which include metropolises such as Hong Kong, Shenzhen, Guangzhou, and Macao. The nine largest cities of the PRD had a combined population of 86 million in 2022; the PRD has become the largest urban area in the world in both size and population. The region's traditional language is Cantonese; in the late 20th century and the 21st century, due to the high inflow of migrant workers coming from other regions, Mandarin has gradually become a lingua franca.

Bangkok, officially known in Thai as Krung Thep Maha Nakhon and colloquially as Krung Thep, is the capital and most populous city of Thailand. The city occupies 1,568.7 square kilometres (605.7 sq mi) in the Chao Phraya River delta in central Thailand and has an estimated population of 11.4 million people as of 2024, 15.9% of the country's population. Over 17.4 million people (25% of Thailand's population) live within the surrounding Bangkok Metropolitan Region as of the 2021 estimate, making Bangkok a megacity and an extreme primate city, dwarfing Thailand's other urban centres in both size and importance to the national economy.

Bangkok traces its roots to a small trading post during the Ayutthaya era in the 15th century, which eventually grew and became the site of two capital cities, Thonburi in 1767 and Rattanakosin in 1782. Bangkok was at the heart of the modernization of Siam during the late 19th century, as the country faced pressures from the West. The city was at the centre of the country's political struggles throughout the 20th century, as Siam—later renamed Thailand—abolished absolute monarchy, adopted constitutional rule, and underwent numerous coups and several uprisings. The city, incorporated as a special administrative area under the Bangkok Metropolitan Administration in 1972, grew rapidly during the 1960s through the 1980s and now exerts a significant impact on Thailand's politics, economy, education, media, and modern society.

Johannesburg (/dʒoʊˈhænɪsbɜːrɡ/ joh-HAN-iss-burg, US also /-ˈhɑːn-/ -⁠HAHN-, Afrikaans: [jʊəˈɦanəsbœrχ]; Zulu and Xhosa: eGoli [ɛˈɡɔːli]; colloquially known as Jozi, Joburg, Jo'burg or "The City of Gold") is the most populous city in South Africa. The City of Johannesburg itself has a population of 5,538,596, while the greater urban agglomeration exceeds 14.8 million, making it a megacity and one of the 100 largest urban areas in the world. Johannesburg is the provincial capital of Gauteng, the wealthiest province in South Africa, and seat of the country's highest court, the Constitutional Court. Situated in the mineral-rich Witwatersrand hills, the city has long been at the epicentre of the international mineral and gold trade. The richest city in Africa by GDP and private wealth, Johannesburg functions as the economic capital of South Africa and is home to the continent's largest stock exchange, the Johannesburg Stock Exchange.

Johannesburg was established in 1886, following the discovery of gold, on what was once farmland. Within a decade, the population surged to over 100,000, driven by the large gold deposits found along the Witwatersrand. Modern Johannesburg is an amalgamation of formerly separate cities, townships and settlements, reflecting apartheid-era spatial segregation policies. Soweto ("South-Western Townships"), designated a "blacks only" city until 1994, is one of the most historically significant areas for modern South Africa. Home to key anti-apartheid leaders, including Nelson Mandela and Desmond Tutu, it became the epicenter of the 1976 Soweto Uprising, where peaceful student protests were met with brutal force. In contrast, Lenasia is predominantly populated by English-speaking Indo-South Africans (people of Indian and South Asian descent). Formerly "white-only" areas include Sandton, known as "Africa's richest square-mile", Randburg and Roodeport.

The amalgamation of Toronto was the creation of the city limits of Toronto, Ontario, Canada after amalgamating, annexing, and merging with surrounding municipalities since the 18th century. The most recent occurrence of amalgamation was in 1998, which dissolved the federation of Metropolitan Toronto and its constituent municipalities, and created the current "megacity" of Toronto.

This article presents a list of cities and towns in Bangladesh. According to the Bangladesh Bureau of Statistics and the Ministry of Local Government, Rural Development and Co-operatives of Bangladesh, there are 532 urban centres in Bangladesh.

The bureau defines an urban centre with a population of 100,000 or more as a "city". Altogether, there are 43 such cities in Bangladesh. 12 of these cities can be considered major cities as these are governed by city corporations. All of city corporation-governed cities currently have a population of more than 200,000, which is not a criterion for the status, because currently 17 cities in Bangladesh have a population of more than 200,000. Besides the 9 major cities, there are 32 other cities in Bangladesh that are not governed by city corporations and rather by municipal corporations. A city with a population of more than 10,000,000 is defined by the bureau as a megacity. Dhaka is the only megacity in Bangladesh according to this definition. Together, Dhaka and the port city of Chittagong account for 48% of the country's urban population.

This is a list of all the 95 cities (with regency-level status) in Indonesia, ranked by population. It excludes urban-characterized settlements such as regency seats, which does not have city status. Indonesia has 93 cities classified as kota (city), one provincial-level capital city (Nusantara), and one provincial-level special city (the Special Capital Region of Jakarta). Population figures are taken from the 2020 census and the more recent official estimates as at mid 2024, all by Statistics Indonesia (BPS).

Jakarta is the largest city and the only megacity in Indonesia, with a population of 10.70 million. As a primate city, Jakarta is nearly four times larger than the second largest city Surabaya. Jakarta, along with Capital City of Nusantara, are unique compared to other cities in Indonesia, since they are technically provinces with a city management. Jakarta is subdivided into five administrative cities and an administrative regency, which are not self-governed (without municipal council nor government budget). Each of Jakarta's five satellite cities also have passed the one million mark in population, with the largest one being Bekasi, while the others are Depok, Tangerang, South Tangerang and Bogor.

Kinshasa (/kɪnˈʃɑːsə/; French: [kinʃasa]; Lingala: Kinsásá), formerly named Léopoldville from 1881–1966 (Dutch: Leopoldstad), is the capital and largest city of the Democratic Republic of the Congo. Kinshasa is one of the world's fastest-growing megacities, with an estimated population of 17.8 million in 2024. It is the most densely populated city in the DRC, the third-most populous city and third-largest metropolitan area in Africa, and the world's twenty-second most populous city and fourth-most populous capital city. It is the leading economic, political, and cultural center of the DRC, housing several industries including manufacturing, telecommunications, banking, and entertainment. The city also hosts some of the DRC's significant institutional buildings, such as the People's Palace, Palace of the Nation, Court of Cassation, Constitutional Court, African Union City, Marble Palace, Martyrs Stadium, Government House, Kinshasa Financial Center, and other national departments and agencies.

The Kinshasa site has been inhabited by Teke and Humbu people for centuries and was known as Nshasa before transforming into a commercial hub during the 19th and 20th centuries. The city was named Léopoldville by Henry Morton Stanley in honor of Leopold II of Belgium. The name was changed to Kinshasa in 1966 during Mobutu Sese Seko's Zairianisation campaign as a tribute to Nshasa village. Covering 9,965 square kilometers, Kinshasa stretches along the southern shores of the Pool Malebo on the Congo River. It forms an expansive crescent across flat, low-lying terrain at an average altitude of about 300 meters. Kinshasa borders the Mai-Ndombe Province, Kwilu Province, and Kwango Province to the east; the Congo River delineates its western and northern perimeters, constituting a natural border with the Republic of the Congo; to the south lies the Kongo Central Province. Across the river sits Brazzaville, the smaller capital of the neighboring Republic of the Congo, forming the world's closest pair of capital cities despite being separated by a four-kilometer-wide unbridged span of the Congo River.

The Guangdong–Hong Kong–Macao Greater Bay Area, commonly referred to as the Greater Bay Area (GBA), is a megalopolis, consisting of nine cities and two special administrative regions in South China. It is envisioned by Chinese government planners as an integrated economic area aimed at taking a leading role globally by 2035.

It is the largest and most populated urban area in the world. The GBA—with a total population of approximately 86 million people—includes nine mega cities of Guangdong province: Guangzhou, Shenzhen, Zhuhai, Foshan, Dongguan, Zhongshan, Jiangmen, Huizhou, and Zhaoqing as well as two special administrative regions, Hong Kong, and Macao (Macau). Hong Kong, Guangzhou, and Shenzhen have been described among the world's 50 "superstar cities". Surrounding the Pearl River Delta with a total area of 56,000 km (comparable in size to Croatia), it is the largest and the richest economic region in South China.
