This statistic shows a forecast of the top ten most populous megacities in 2030. By 2030, Tokyo will be the most populous city in the world, with a projected 37 million inhabitants.

The world is a crowded place, with more than 7 billion people on the planet as of 2014. About half of this population lives in urban areas, and ongoing migration into city centers has given rise to the megacity—a metropolitan area with 10 million people or more. This story map was produced by Esri's story map team. It is a customization of the Esri Story Map Journal app, and was created in collaboration with the Smithsonian Institution.

This statistic provides a projection of the gross domestic product (GDP) of major megacities worldwide in 2030. As of this time, it is projected that the GDP of Tokyo, Japan, will reach 40 billion U.S. dollars.

This dataset provides a comprehensive overview of the population statistics for 800 largest cities in the world, detailing the population estimates for the years 2023 and 2024. Additionally, it includes the calculated growth rate for each city over this period. This dataset can be instrumental for urban studies, demographic analysis, and economic research. Columns Description • City: The name of the city. • Country: The country where the city is located. • Population (2024): Estimated population of the city for the year 2024. • Population (2023): Estimated population of the city for the year 2023. • Growth Rate: The rate of population growth from 2023 to 2024. This is calculated as the difference between the 2024 and 2023 populations, divided by the 2023 population.

As of 2025, Tokyo-Yokohama in Japan was the largest world urban agglomeration, with 37 million people living there. Delhi ranked second with more than 34 million, with Shanghai in third with more than 30 million inhabitants.

List of the world's major cities (above 15,000 inhabitants)

This dataset lists cities which consists of above 15,000 inhabitants. Each city is associated with its country and sub-country to reduce the number of ambiguities. Subcountry can be the name of a state (eg in the United Kingdom or the United States of America) or the major administrative section (eg "region" in "France").

The below dataset shows the top 800 biggest cities in the world and their populations in the year 2024. It also tells us which country and continent each city is in, and their rank based on population size. Here are the top ten cities:

• Tokyo, Japan - in Asia, with 37,115,035 people.
• Delhi, India - in Asia, with 33,807,403 people.
• Shanghai, China - in Asia, with 29,867,918 people.
• Dhaka, Bangladesh - in Asia, with 23,935,652 people.
• Sao Paulo, Brazil - in South America, with 22,806,704 people.
• Cairo, Egypt - in Africa, with 22,623,874 people.
• Mexico City, Mexico - in North America, with 22,505,315 people.
• Beijing, China - in Asia, with 22,189,082 people.
• Mumbai, India - in Asia, with 21,673,149 people.
• Osaka, Japan - in Asia, with 18,967,459 people.

This database provides the construction of Large Urban Regions (LUR) in the world. A Large Urban Region (LUR) can be defined as an aggregation of continuous statistical units around a core that are economically dependent on this core and linked to it by economic and social strong interdependences. The main purpose of this delineation is to make cities comparable on the national and world scales and to make comparative social-economic urban studies. Aggregating different municipal districts around a core city, we construct a single large urban region, which allows to include all the areas of economic influence of a core into one statistical unit (see Rozenblat, 2020 or Rogov & Rozenblat, 2020 for Russia). In doing so we use four principal urban concepts (Pumain et al., 1992): local administrative units (Municipality or localities: MUNI), morphological urban area (MUA), functional urban area (FUA), and conurbation that we call Large Urban Region (LUR). The LURs are the spatial extensions of the influence of one or several FUAs or MUAs. MUAs and FUAs are defined by various national or international sources. We implemented LURs using criteria such as the population distribution among one or several MUAs or FUAs, road networks, access to an airport, distance from a core, and presence of multinational firms. FUAs and MUAs perimeters, if they form a part of a LUR, belong to a unique LUR. In this database, we provide the composition of the LURs in terms of local administrative units (MUNI), Morphological Urban Areas (MUA), and Functional Urban Areas (FUA).

This last update provides new LURs for the 54 African Countries (see Rogromel & Rozenblat, 2024) and some corrections for China.

It includes now 1'828 LURs composed of 130'283 localities.

This statistic provides the share of the total land area that is built-up in the ** largest cities around the world in 2015. As of this year, about ***** percent of Los Angeles' land area was considered built-up.

Urban open space (UOS) plays an important role, especially in areas characterized by intense social and economic activity. However, UOS mapping products for major cities around the world are lacking. To fill this gap, we used a deep learning–based method based on a tiny-manual annotation strategy to map UOS and produced a 1.19 m resolution UOS map of 2021 in urban areas of global 169 megacities with populations of over 3,000,000 people (namely the OpenspaceGlobal product). It contains five urban open space categories, namely "park and green spaces," "outdoor sports spaces," "transportation spaces," "water body spaces", and "background". The OpenspaceGlobal product can promote a better understanding of human-made space surfaces in major cities worldwide and facilitate functions such as urban livability estimation, urban planning, and sustainable development. The OpenspaceGlobal product is free to use for non-commercial forms including scientific research and science promotion under proper citation.

In 2023, New York led the ranking of the largest built-up urban areas worldwide, with a land area of ****** square kilometers. Boston-Providence and Tokyo-Yokohama were the second and third largest megacities globally that year.

World Cities provides a basemap layer for the cities of the world. The cities include national capitals, provincial capitals, major population centers, and landmark cities. Population estimates are provided for those cities listed in open source data from the United Nations Statistics Division, United Nations Human Settlements Programme, and U.S. Census Bureau.

List of major cities in the world

Data

The data is extracted from geonames, a very exhaustive list of worldwide toponyms.

This datapackage only list cities above 15,000 inhabitants. Each city is associated with its country and subcountry to reduce the number of ambiguities. Subcountry can be the name of a state (eg in United Kingdom or the United States of America) or the major administrative section (eg ''region'' in France''). See admin1 field on geonames website for further info about subcountry.

Notice that : * some cities like Vatican city or Singapore are a whole state so they don't belong to any subcountry. Therefore subcountry is N/A. * There is no guaranty that a city has a unique name in a country and subcountry (At the time of writing, there are about 60 ambiguities). But for each city, the source data primary key geonameid is provided.

Preparation

You can run the script yourself to update the data and publish them to github : see scripts README

This statistic shows the population growth rate of the top twenty largest urban agglomerations in the United States from 2000 to 2030. Between 2025 and 2030, the average annual population growth rate of the New York-Newark agglomeration is projected to be roughly **** percent.

Based on a collection of estimates, over the past 9,000 years, there have been at least 48 cities with a claim to the title of "the world's most populous city". While these can be found on four separate continents, the majority are concentrated in three major regions; 12 of these cities were in present-day Iraq or Syria (then-Mesopotamia), nine were in China, and seven in Egypt. Additionally, many of these cities were found across the Mediterranean, not only during Antiquity (Alexandria, Carthage, and Rome), but also during the Middle Ages (Constantinople, Cordova, and Fez), highlighting the economic significance of this region throughout history.

Many of the older entries in this list are now just archeological sites, although several have been continuously inhabited for millennia, such as Luoyang and Xi'an in China, which both have populations of several million in 2022. It may also be possible that the first entry, Jericho, is the world's oldest, continuously inhabited settlement, although this is a topic of debate.
