Visit the Most Populated Cities on Earth

This is a virtual travel to the world's most populous cities like New York, Tokyo, Shanghai, London, Hong Kong, Chicago, Buenos Aires, Bangkok, Seoul, Los Angeles, Mexico City and so on.

Which is the largest city on the planet, this issue is still unresolved but sometimes the subject of small talk. On your next casual conversation you may impress your audience when you state that by far the largest city is Chongqing, because most certainly nobody ever had heard of that city.

Chongqing in southwest China is one of the emerging Megacities with a population of more than 32 million people, sprawled over an area of 82,400 km² (this is twice the size of Switzerland with 41,285 km²). Chongqing carved out of Sichuan province in 1997, is de facto a Chinese province with the status of a provincial-level municipality like Shanghai, Beijing and Tianjin.
And this should be the largest? Actually Chongqing's core population is about 7.5 million.

The largest, the biggest, or the most populous cities?
In many languages this terms are interchangeable, meaning the largest city of a country is also the most populous.
In the chart below there they are, the largest cities in the world, ranked by the population of a city's urban/metropolitan area.

What is a City?
The challenge is, ranking these cities is like to compare apples and oranges.
The common ground is: there is a city and there must be people, so lets count them. The problem begins with the definition of a city, easy you say?
A build-up of many buildings with many citizens is a city, right?

The largest city on Earth?
Lets look at Tokyo, often referred to as the largest city on Earth. But this is only true when you take the built up area of Tokyo and add the urban expansion of Chiba, Kawasaki, Sagamihara, Saitama, and Yokohama, which actually is Japan's second most populous city.

In the course of time, the fringe areas of all those cities have been growing together and now they form one massive conurbation, a megalopolis, a sprawling sea of buildings, and streets, with only virtual borders - and living within, 28% of Japan’s entire population.

To learn more about the cities, this page provides links to the official city or municipality government website and/or to the official travel and tourism information site or other tourism guides related to a city. A city's websites usually publish also information for visitors and tourists about cultural events, festivals, sightseeing and much more.

Note: Population figures are for latest available years. The ranking is relative because of the diverse latest available figures of the city population.

Lets make it bigger.
For those who are interested why the population figures for major world urban areas vary so greatly by various sources and publications, can read about the difficulty to get almost realistic population figures for metropolitan areas and cities.

For example New York City is listed in various World-Rankings of the Most Populous Cities, Urban Areas, Agglomerations, Conurbations etc. as follows:

No. 2 (pop. 30 400 000) in World Gazetteer in 2004, according to Richard L. Forstall (see below)
No. 6 (pop. 21 900 000) in City Population (The Principal Agglomerations of the World)
No. 3 (pop. 21 295 ,000) in Wendell Cox Consultancy's Demographia (Largest Urban Areas in the World: 2009)
No. 4 (pop. 19 750 000) in Wikipedia (List of metropolitan areas by population)
No. 5 (pop. 19 500 000) in Richard L. Forstall (Which are the largest?)
No. 2 (pop. 19 000 000) in United Nations Population Division (Urban Agglomerations 2007)
No. 5 (pop. 16 626 000) in (Largest Cities of the World - by population)

the figures for other cities vary accordingly by each publication.

The official population figure for New York City, according to U.S. Census Bureau is 8 363 710 (July 1, 2008)

Some publication just don't mention, that this figures are not for the City of New York, instead of the New York-Northern New Jersey-Long Island, New York-New Jersey-Pennsylvania Metropolitan Statistical Area (MSA) including beside New York, the cities of Jersey City (NJ), Newark (NJ), Paterson (NJ), and Yonkers (NY), spread out over three states, New Jersey, New York, and Connecticut.
According to U.S. Census Bureau the population of 'New York-Northern New Jersey-Long Island, NY-NJ-PA is 19 006 798.

Urban area is the area that a city or town occupies, it is created and further developed by the process of urbanization.

** Urban agglomeration is an extended city or town area comprising the built-up area of a central place (usually a municipality) and any suburbs linked by continuous urban area, similar to Metropolitan Area.

Metropolitan area (Metro) is a large population center consisting of a large urban area (core city) together with adjacent communities and satellite cities plus its adjacent zone of influence including rural areas.
