engineering careers  Infographic: What are the worlds biggest cities going to be in 2100?

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 in 2100!

In 2010, Tokyo, Japan had the biggest population of any city on the planet with a population of 36 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 even further ahead, right? Wrong.

Tokyo 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.

In this research led piece, have been tracking the top 20 cities in the world with the highest population back in 2010 and following their projected population increase or decrease over the years. If they drop out of the top 20, the city that overtakes it joins the chart and replaces it.
