In the last decades, the population worldwide was influenced by economic factors. The search for a good job and the better living conditions that can be found in large cities attracted even more people. This trend can be observed at the global level and if we take each large city in part we can definitely conclude that the largest cities in the world are still growing.
The largest cities can be evaluated in two different ways. The first is to take into consideration only the population within the city borders (without the suburbs) while the second comparison take into consideration all people living in the metropolitan area.
For our top ten largest cities we choose the first method of listing which includes only the population living inside the political and administrative boundaries of the city. To get a clear look on the real urban agglomeration you can also find the area and the density information for each city.
