|The world's cities are known also as metropolises and represent large areas of human urbanisation where housing and industry spread outwards from the centre, often creating a sprawling sea of concrete that stretches further than the human eye can possibly hope to see. The populations of these cities are ever increasing as urban development grows.|
The great cities of the world in terms of sheer size and importance include Tokyo, New York, London, Seoul, Bombay, Jakarta, Shanghai, Cairo, Bangkok, Moscow, Berlin, Paris, Istanbul and Sydney. New York was the first of the world's cities to ever reach 1 million inhabitants and has a current population of 7.5 million.
Two of the world's largest metropolises are Seoul, South Korea and Tokyo, Japan. Shinjuku station on the Yamanote Line in Tokyo has the claim of allowing 2 million passengers to pass through its turnstiles daily. Most of the world's great cities have subway systems for ease of access although those that do not usually have tramways.
Capital cities are usually the biggest in the particular country although this is not always the case. Ankara is the capital of Turkey although many confuse Istanbul as being the capital. Sydney is another common misconception as the capital of Australia, when in fact it is Canberra.
