AT THE beginning of February, somewhere in London, a maternity ward welcomed the city's 8,615,246th inhabitant. The mayor of London reckons that the British capital has now surpassed its previous population peak set in 1939. But if it occasionally feels cramped on the Tube, the task for other city planners around the world looks far more daunting. Nearly 9% of the world's population will be living in just 41 megacities (those with more than 10m inhabitants) by 2030. Even adding in the residents of the greater urban area, London only earned megacity status in 2013, according to the UN. Tokyo is estimated to be home to 38m people. Our interactive map above tracks global city population shifts and forecasts over time. Related:  Megacities, Mega regionsCITIES & MEGACITIES

China’s Pearl River Delta overtakes Tokyo as world’s largest megacity | Cities China’s Pearl River Delta has overtaken Tokyo to become the world’s largest urban area in both size and population, according to a report from the World Bank. The megacity – which covers a significant part of China’s manufacturing heartland and includes the cities of Shenzhen, Guangzhou, Foshan and Dongguan – is now home to more people than the countries of Canada, Argentina or Australia. Urbanisation which took place over a period of several decades in Europe and North America is happening in just a few years in East Asia, which already contains eight megacities (with populations above 10 million) and 123 cities with between one and 10 million people. With almost two-thirds of the region’s population (64%) still non-urban at present, several hundred million are expected to move to cities over the next 20 years as economies shift from agriculture to manufacturing and services, according to East Asia’s Changing Urban Landscape: Measuring a Decade of Spatial Growth.

Urban world: Mapping the economic power of cities Six hundred cities—the City 600—are projected to generate more than 60 percent of global growth to 2025. Within this group, companies need to adjust their strategy to include the 577 fast-growing “middleweight cities.” The urban world is shifting. Open interactive popup Today, major urban areas in developed-regions are, without doubt, economic giants. But by 2025, one-third of these developed-market cities will no longer make the top 600; and one out of every 20 cities in emerging-markets is likely to see its rank drop out of the top 600. To help companies find growth opportunities and policymakers to manage the increasing complexity of larger cities more effectively, MGI has built on its extensive research on the urbanization of China, India, and Latin America to develop Cityscope, a database on more than 2,000 metropolitan areas around the world, the largest of its kind. Podcast The urban landscape is shifting.

Megacity A megacity is usually defined as a metropolitan area with a total population in excess of ten million people.[1] A megacity can be a single metropolitan area or two or more metropolitan areas that converge. The terms conurbation, metropolis and metroplex are also applied to the latter. As of 2016, there are 35 megacities in existence, Chennai being the latest. The largest of these are the metropolitan areas of Tokyo and Jakarta, each of these having a population of over 30 million inhabitants. Tokyo is the largest metropolitan area, while Shanghai is the largest city proper. Largest cities[edit] This is the list of largest cities and metropolitan areas as of 2016. History[edit] The term "megacity" entered common use in the late 19th or early 20th centuries, one of the earliest documented uses being by the University of Texas in 1904.[10] Initially the United Nations used the term to describe cities of 8 million or more inhabitants, but now uses the threshold of 10 million.[11] Growth[edit]

List of European cities by population within city limits - Wikipedia This is a list of the largest cities in Europe ranked according to population within their city limits. It deals exclusively with the areas within city administrative boundaries (municipalities) as opposed to urban areas or metropolitan areas, which are generally larger in terms of population than the main city. The list includes cities geographically situated in Europe, using the conventional definition of its boundaries. It is notable that Istanbul's commercial and historical center lies on the European side, and about a third of its population lives on the Asian side.[1] 64.7% of the residents live on the European side, and 35.3% on the Asian side.[2] According to the population within city limits value listed below, the city as a whole is larger than Moscow. However, the European side is not as populous as Moscow. Largest cities[edit] Note: The cities are sorted by the column labelled Population within city limits.

Bangkok Becomes First Megacity to Mull Move to Higher Ground November 25th, 2011 by Susan Kraemer After another year marked by months of epic flooding in the capital city of 12 million, this month AFP reports that lawmakers in Thailand have submitted a parliamentary motion to begin discussions of building a second capital or moving Bangkok to higher ground. Sataporn Maneerat, a Puea Thai party MP, told AFP Thailand should think about moving the capital or looking to another city for future developments and investments. “Another 19 Puea Thai MPs and I have signed and submitted a motion to parliament to seek approval to set up a committee, to consider whether the capital should be moved or if Thailand should have a second capital,” he said. “Bangkok is sinking every year. According to a World Bank estimate in 2009: Like New Orleans, Bangkok is a low-lying coastal city built on swampy ground. The rapidly developing capital is gradually overwhelming the marshy ground, unable to support the weight of the burgeoning megacity above, and is sinking.

Dar es Salaam: Africa's next megacity? 30 July 2012Last updated at 20:34 ET By Joe Boyle BBC News, Dar es Salaam Visionaries hope for a modern metropolis modelled on Singapore, but pessimists fear the emergence of another dirt-poor city of slums. Dar es Salaam is one of the world's fastest growing cities, and it has reached its tipping point. In the dark basement of the cavernous Kariakoo market, dozens of traders gather at tiny makeshift stalls, arranging fruit and vegetables into neat piles. Rolens Elias arrived seven years ago from a village near Morogoro, about 150km to the west. "It has been hard to set up a life here," he says. As he arranges his tomatoes, a group of his friends gather around and chip in with their own stories. Their stories are repeated many thousands of times across the city. Every day new arrivals flood in, many of them setting up home in hastily erected shacks, many others sleeping on the streets. Superficially at least, his dream seems within reach. But Dar es Salaam is a long way from Singapore.

Cities: an interactive data visual This is an updated and expanded version of the data visual first posted in June 2014. It draws on a new dataset from the United Nations Population Division. It also covers all cities with 500,000-plus inhabitants, compared to the earlier version that covered cities with 750,000-plus inhabitants. Guide to use To use the above data visual click on the dateline button at the top to slide the scale to the right and advance through the years, enabling you to see how and where cities of 500,000+ inhabitants have grown since 1800, plus predictions for future growth up to 2030. A summary of the wider global changes taking place can be found at the top, while users who hover their mouse over individual cities can discover precise data regarding those cities. Alternatively, click on the 'grid' view towards the top right of the visual to see a chart of the individual cities and where they rank in terms of population.

Asia to dominate 21st century megacities 21 June 2011Last updated at 00:19 Mass urbanisation, the increasing concentration of populations into towns and cities, is one of the defining characteristics of industrialised economies. By the middle of the 20th Century the two biggest economies, the USA and Japan, had created a new urban phenomenon: the megacity. This image of the earth at night shows where the population of the world is crowding together into major urban areas. The first megacities were New York and Tokyo, and by 1980 Tokyo had almost twice as many inhabitants as New York. By the early 1990s, vast urban centres in developing countries were acting as engines for economic growth. By 2000 Europe and Africa had their first megacities in Moscow and Cairo, but there were also another four megacities in Asia, including Karachi in Pakistan and Dhaka in Bangladesh. By 2010 there were 21 megacities with Paris becoming the first in western Europe.
