The United States of America encompasses a very large amount of land, both what is generally considered dry land and even more covered by salt water. Approximately 40% of the dry land (31% federal and 9% states) and essentially 100% of the undersea lands are owned mostly by the government of the United States with the rest being owned by coastal states. Of all the US lands—submerged and not—the federal or state government owns 73% of them.
