Population
The population in Tokyo is rising at an extremely fast rate, to the point that the city is becoming extremely over crowded. In 1950, Tokyo was only populated by 7 million people, but by 1965 it had over 20 million people and in 1975, it had over 23 million. Tokyo was also the first city to have over 10 million people living there, and that was just by 1962. Tokyo is quickly becoming an overcrowded city, as 20,000 people live in every square kilometre. The population has risen to a massive 37.8 million residents as of February 2nd 2015, and the majority of them are 0-50 year old males.
