The White House is located in a federal district on the eastern coast of the United States. Today, the majority of states are located west of Washington, D.C., and the White House.

As the nation grew stronger and more populous, presidents began to seek additional territory and expanded westward across the continent, eventually reaching the Pacific coast.
