The geography of the United States impacts the possible regions people settle in.
Areas that tend to be flat (or small amounts of small hills) tend to be the most population areas because it is easier to build houses, apartments, etc etc. However there is very few places people have settled where National Parks and Mountains are located because it is unstable and extremely difficult to make a house in that region.
