When we think of overpopulated cities, we think of big cities like Manhattan or Los Angeles. But did you know that our most populated cities in America don't even make it in the top 15 when compared to other parts of the world? Check out the most populated places on the planet, a list compiled by Imgur-user Undulate with extra information and photos supplied by Heavy.
Area: 59.5 km2 (22.96 sq mi)
Population density: 26,939/km2 (69,771/sq mi)
Because Manhattan has so many office buildings, it swells to about 3.94 million during the day, giving a population density of about 171,000 per square mile / 66,000 per square km.
The Upper West Side is primarily residential, with 209,000 people / 1.9 square miles, meaning about 110,000 people per square mile / 42,500 per square kilometer.
