The world's largest urban area, Tokyo (37.4 million), has almost the same population as the entire country of Canada (37.6 million).

The 2018 data on the 30 largest cities of the world,compiled by theUnitedNations Population Division, reflects the best possible estimates of the populations of these huge cities. Dynamicpopulation growthmakes determining the "exact" population of a city difficult, especially in a developing nation.

If you're wondering what these megacities will look like inthe​ ​future, the UN has also projected their population for the year 2030.

Also, in 2018, 27 of the megacities were located in the less developed regions, and by 2030, nine additional cities are estimated to be located there.
