Really? I have the opposite viewpoint. It's amazing how much of the US has zero people living in it.

Remember, if the census block has is filled in, it could only have 1 or 2 people living in it (i.e. a farm).

We have so much dam space in the US it's mind blowing.

A lot of the space is not really suitable for dense inhabitation, tho. (or any at all for a smaller subset)
