The United States Census Bureau defines four statistical regions, with nine divisions.The Census Bureau region definition is "widely used [...] for data collection and analysis," and is the most commonly used classification system.
Puerto Rico and other US territories are not part of any census region or census division.
The ten standard federal regions were established by OMB (Office of Management and Budget) Circular A-105, "Standard Federal Regions," in April 1974, and required 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Note: OMB Circular A-105 was rescinded on June 8, 1995.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. These twelve Federal Reserve Banks together form a major part of the Federal Reserve System, the central banking system of the United States.

The Federal Circuit is not a regional circuit. Its jurisdiction is nationwide but based on the subject matter.
The Bureau of Economic Analysis defines regions for comparison of economic data.

PADD I can also be subdivided into 3 Subdistricts:

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. He also argues that conventional national and state borders are largely artificial and irrelevant, and that his "nations" provide a more accurate way of understanding the true nature of North American society.

This is a list of historic regions of the United States that existed at some time during the territorial evolution of the United States and its overseas possessions, from the colonial era to the present day.

The last section lists informal regions from American vernacular geography known by popular nicknames and linked by geographical, cultural, or economic similarities, some of which are still in use today.
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.

Tri-state area is an informal term in the eastern contiguous United States for any of several regions associated with a particular town or metropolis that, with adjacent suburbs, lies across three states. Some of these involve a state boundary tripoint. Other tri-state areas have a more diffuse population that shares a connected economy and geography — especially with respect to geology, botany, or climate — such as the tri-state area of eastern Pennsylvania, southern New Jersey and northern Delaware. The term "tri-state area" is often present in movies, radio and television commercials.
USA Volleyball (USAV) is a non-profit organization which is recognized as the national governing body of volleyball in the United States by the Fédération Internationale de Volleyball (FIVB) and the United States Olympic Committee (USOC).

A Grotto is an internal organization of the National Speleological Society (NSS). They generally function as the local NSS chapter/club.

The fauna of the United States of America is all the animals living in the Continental United States and its surrounding seas and islands, the Hawaiian Archipelago, Alaska in the Arctic, and several island-territories in the Pacific and in the Caribbean. The U.S. has many endemic species found nowhere else on Earth. With most of the North American continent, the U.S. lies in the Nearctic, Neotropic, and Oceanic faunistic realms, and shares a great deal of its flora and fauna with the rest of the American supercontinent.

Regional geology is the geological study of large-scale regions. Usually, it encompasses multiple geological disciplines to piece together the history of an area. It is the geologic equivalent of regional geography. The size and the borders of each region are defined by geologically significant boundaries and by the occurrence of geologic processes. Examples of geologically significant boundaries are the interfingering facies change in sedimentary deposits when discussing a sedimentary basin system, or the leading or boundary thrust of an orogen.
The 2011–12 North American winter refers to winter in North America as it occurred across the continent from late 2011 through early 2012.

The primary outlier was Alaska, which experienced its coldest January on record.
