Answer: False
Explanation: Urban areas are more populous (per capita) than suburban areas. They also have more buildings and attractions. Take Nyc (New York City) as an example:
New York City is the largest urban city in America with a landmass of 4,669.0 sq mi
Now let's compare it to the largest suburban city:
Perth, Australia is the largest suburban city in the world with over 150 kilometers, it's still growing to this day
4,669.0 sq mi > 150
So, this leads to Urban areas being more populated (per capita) than suburban areas.
