The ten standard federal regions were established by OMB (Office of Management and Budget) Circular A-105, "Standard Federal Regions", in April 1974, and went into use for all executive agencies. In recent years, some agencies have tailored their field structures to meet program needs and facilitate interaction with local, state, and regional counterparts. However, the OMB must still approve any departures.
Note: OMB Circular A-105 was rescinded on June 8, 1995.
The Federal Reserve Act of 1913 divided the country into twelve districts with a central Federal Reserve Bank in each district.

The term 'United States', when used in the geographical sense, refers to the contiguous United States, the state of Alaska, the island state of Hawaii, the five insular territories of Puerto Rico, Northern Mariana Islands, U.S. Virgin Islands, Guam, and American Samoa, and minor outlying possessions. The United States shares land borders with Canada and Mexico and maritime borders with Russia, Cuba, The Bahamas, and other countries, in addition to Canada and Mexico. The northern border of the United States with Canada is the world's longest bi-national land border.
The Western United States is the region comprising the westernmost states of the United States. As American settlement in the U.S. expanded westward, the meaning of the term the West changed. Before about 1800, the crest of the Appalachian Mountains was seen as the western frontier. The frontier moved westward and eventually the lands west of the Mississippi River were considered the West.
The Nine Nations of North America is a 1981 book by Joel Garreau, in which the author suggests that North America can be divided into nine nations, which have distinctive economic and cultural features.

The work has been called "a classic text on the current regionalization of North America".

Classification of Indigenous peoples of the Americas is based upon cultural regions, geography, and linguistics. Anthropologists have named various cultural regions, with fluid boundaries, that are generally agreed upon with some variation. These cultural regions are broadly based upon the locations of Indigenous peoples of the Americas from early European and African contact beginning in the late 15th century. When Indigenous peoples have been forcibly removed by nation-states, they retain their original geographic classification. Some groups span multiple cultural regions.
The North American Cordillera, sometimes also called the Western Cordillera of North America, the Western Cordillera or the Pacific Cordillera, is the North American portion of the American Cordillera, the mountain chain system (cordillera) along the western coast of the Americas.
