The United Nations has predicted the world’s population to be 9.8 billion in 2050. However, that is set to soar to an astonishing 11.2 billion people by the end of the decade – so what will be the largest city in the world in 2100!

In 2010, Tokyo, Japan had the the largest city in the world with a population of 36 Million people. Compare that to the top 20 biggest cities in England which have a combined total population of only 26 Million people.

That was nearly 15 million more than Delhi, India, which had the second highest population. Fast forward 90 years you’d expect Tokyo to be one of the most populous cities cities in the world? Wrong. It probably won’t even be in the top 15 major world cities.

Tokyo’s city population is predicted to not even make it into the top 20 cities in the world. In fact, only 6 of the top 20 cities with the highest population in 2010 are predicted to still be in the top 20 by 2100. Over the next decade we will see a radical change in the 50 biggest cities in the world as the list of the most populous city shift.
