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.
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. Missouri is the only U.S. state to have two Federal Reserve locations within its borders, as some states are divided into more than one district.
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.
The Energy Information Administration currently uses the PADD system established by Petroleum Administration for War in World War II.It is used for data collection on refining petroleum and its products. Each PADD is subdivided into refining districts.
PADD I can also be subdivided into 3 Subdistricts:
The Agricultural Research Service (ARS) is the research arm of the USDA. The ARS has sectioned their work into five geographic regions:
The U.S. National Park Service divides the U.S. into the following regions for U.S. National Park purposes:
The U.S. Minor Outlying Islands are not part of any U.S. National Park Service region.
There are also multi-territory regions:
In Connecticut, there are 14 official regions, each with a regional government that serves for the absence of county government in Connecticut. There are also a fair number of unofficial regions in Connecticut with no regional government.

The term "United States", when used in the geographical sense, is 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, United Kingdom, Dominican Republic, and the Bahamas 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 East Coast of the United States, also known as the Eastern Seaboard, the Atlantic Coast, and the Atlantic Seaboard, is the coastline along which the Eastern United States meets the North Atlantic Ocean. The coastal states that have shoreline on the Atlantic Ocean are, from north to south, Maine, New Hampshire, Massachusetts, Rhode Island, Connecticut, New York, New Jersey, Delaware, Maryland, Virginia, North Carolina, South Carolina, Georgia, and Florida.
The Western United States is the region comprising the westernmost states of the United States. As European settlement in the U.S. expanded westward through the centuries, 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. 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. The work has been called "a classic text on the current regionalization of North America".
In the United States of America, an interstate compact is an agreement between two or more states. Article I, Section 10 of the United States Constitution provides that "No State shall, without the Consent of Congress... enter into any Agreement or Compact with another State." Consent can be obtained in one of three ways. First, there can be a model compact and Congress can grant automatic approval for any state wishing to join it, such as the Driver License Compact. Second, states can submit a compact to Congress prior to entering into the compact. Third, states can agree to a compact then submit it to Congress for approval, which, if it does so, causes it to come into effect. Not all compacts between states require explicit Congressional approval – the Supreme Court ruled in Virginia v. Tennessee that only those agreements which would increase the power of states at the expense of the federal government required it.
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.
A National Heritage Area is a site designated by United States and intended to encourage historic preservation of the area and an appreciation of the history and heritage of the site.

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 New York, New Jersey, and Connecticut. The term "tri-state area" is often present in movies, radio and television commercials.
Indigenous peoples of the Northeastern Woodlands include Native American tribes and First Nation bands residing in or originating from a cultural area encompassing the northeastern and Midwest United States and southeastern Canada. It is part of a broader grouping known as the Eastern Woodlands. The Northeastern Woodlands is divided into three major areas: the Coastal, Saint Lawrence Lowlands, and Great Lakes-Riverine zones.

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 2011–12 season by and large saw above normal average temperatures across North America, with the contiguous United States encountering its fourth-warmest winter on record along with an unusually low number of significant winter precipitation events.
