Metropolis (Mexico city)
 

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 sprawling ocean of buildings, and streets, with only virtual borders - and 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.
