Core-based statistical area

A core-based statistical area (CBSA) is a U.S. geographic area defined by the Office of Management and Budget (OMB) that consists of one or more counties (or equivalents) anchored by an urban center of at least 10,000 people plus adjacent counties that are socioeconomically tied to the urban center by commuting. Areas defined on the basis of these standards applied to Census 2000 data were announced by OMB in June 2003. These standards are used to replace the definitions of metropolitan areas that were defined in 1990. The OMB released new standards based on the 2010 Census on July 15, 2015.

List of United States cities by area

This list ranks the top 150 U. S. cities by land area. Total areas including water are also given, but note that, when ranked by total area, a number of coastal cities appear disproportionately larger. San Francisco is an extreme example: water makes up nearly 80% of its total area of 232 square miles (601 km2). Note also that in many cases a city may be geographically large primarily because its municipal government has merged with the government of the surrounding county. In some cases the county no longer exists, while in others the arrangement has formed a consolidated city–county (or city-borough in Alaska, or city-parish in Louisiana); these are shown in bold. Cities that are not consolidated with or part of any county are independent cities, indicated with two asterisks (**). All data is from the 2010 United States Census.

List of United States urban areas

This is a list of urban areas in the United States as defined by the United States Census Bureau, ordered according to their 2010 census populations. In the table, UA refers to "urbanized area" (urban areas with population over 50,000) and UC refers to "urban cluster" (urban areas with population less than 50,000). The list includes urban areas with a population of at least 50,000.

For the 2010 census, the Census Bureau redefined the classification of urban areas to "a densely settled core of census tracts and/or census blocks that meet minimum population density requirements, along with adjacent territory containing non-residential urban land uses as well as territory with low population density included to link outlying densely settled territory with the densely settled core. To qualify as an urban area, the territory identified according to criteria must encompass at least 2,500 people, at least 1,500 of which reside outside institutional group quarters." These criteria result in several large urban agglomerations that encompass multiple urban areas from the 2000 census. The Census Bureau is currently considering whether to split up the larger agglomerations, but published potential agglomerations in August 2010.

List of cities by population in New England

This is a list of the top 150 New England cities and towns by population based on the 2010 census.

List of largest cities of U.S. states and territories by population

This is a list of the five most populous incorporated places in all 50 U.S. states, the District of Columbia, and the 5 inhabited territories of the United States. The capital city of each state or territory is italicized.

List of metropolitan statistical areas

The United States Office of Management and Budget (OMB) has defined 383 metropolitan statistical areas (MSAs) for the United States and seven for Puerto Rico. The OMB defines a Metropolitan Statistical Area as one or more adjacent counties or county equivalents that have at least one urban core area of at least 50,000 population, plus adjacent territory that has a high degree of social and economic integration with the core as measured by commuting ties.

List of mountains of the United States

This list includes significant mountain peaks and high points located in the United States arranged alphabetically by state, district, or territory. The highest peak or point in each state, district or territory is noted in bold.

List of states and territories of the United States by population density

This article includes a sortable table listing the 50 states, the territories, and the District of Columbia by population density, population rank, and land area. It also includes a sortable table of density by states, territories, divisions and regions by population rank and land area, and a sortable table for density by states, divisions, regions and territories in square miles and square kilometers.

Population density is calculated as resident population divided by total land area. Resident population is from the United States Census Bureau estimates for July 1, 2015 (for the 50 states, DC and Puerto Rico), and from the 2015 United Nations Department of Economic and Social Affairs for territories besides Puerto Rico. In the second table, territories data (except Puerto Rico) is from the 2010 Census. Total land area is from the 2010 Census.The population density of the United States is relatively low compared to many other developed countries due to its size. For example, the population density of the U.S. is one-twelfth that of the Netherlands and one-fifteenth that of South Korea.

Lists of populated places in the United States

The following is a list of lists of the cities, towns and villages of the United States separated by state, territory or district name.

Metropolitan statistical area

In the United States, a metropolitan statistical area (MSA) is a geographical region with a relatively high population density at its core and close economic ties throughout the area. Such regions are neither legally incorporated as a city or town would be, nor are they legal administrative divisions like counties or separate entities such as states; because of this, the precise definition of any given metropolitan area can vary with the source. A typical metropolitan area is centered on a single large city that wields substantial influence over the region (e.g., New York City or Philadelphia). However, some metropolitan areas contain more than one large city with no single municipality holding a substantially dominant position (e.g., Dallas–Fort Worth metroplex, Norfolk-Virginia Beach (Hampton Roads), Riverside–San Bernardino (Inland Empire) or Minneapolis–Saint Paul (Twin Cities)). MSAs are defined by the U.S. Office of Management and Budget (OMB) and used by the Census Bureau and other federal government agencies for statistical purposes.

Micropolitan statistical area

United States micropolitan statistical areas (µSA, where the initial Greek letter mu represents "micro-"), as defined by the Office of Management and Budget (OMB), are labor market areas in the United States centered on an urban cluster (urban area) with a population of at least 10,000 but fewer than 50,000 people. The micropolitan area designation was created in 2003. Like the better-known Metropolitan Statistical Areas, a micropolitan area is a geographic entity used for statistical purposes based on counties and county equivalents. The OMB has identified 536 micropolitan areas in the United States.

The term "micropolitan" gained currency in the 1990s to describe growing population centers in the United States that are removed from larger cities, in some cases by 100 miles (160 km) or more.

Micropolitan cities do not have the economic or political importance of large cities, but are nevertheless significant centers of population and production, drawing workers and shoppers from a wide local area. Because the designation is based on the core urban cluster's population and not on that of the whole area, some micropolitan areas are actually larger than some metropolitan areas. For example, the Ottawa–Peru, IL Micropolitan Statistical Area had a 2010 census population of 154,908. That would put its total population ahead of roughly 100 individual locations classified as a Metropolitan Statistical Area in 2010. The largest of the areas, around Claremont and Lebanon, New Hampshire, had a population in excess of 218,000 in 2010; Claremont's population was only 13,355 in that year's census, and Lebanon's population was only 13,151.

Political divisions of the United States

Political divisions (or administrative divisions) of the United States are the various recognized governing entities that together form the United States — states, the District of Columbia, territories and indian reservations.

The primary first-level political (administrative) division of the United States is the state. There are 50 states, which are bound together in a union with each other. Each state holds governmental jurisdiction over a defined geographic territory, and shares its sovereignty with the United States federal government. According to numerous decisions of the United States Supreme Court, the 50 individual states and the United States as a whole are each sovereign jurisdictions.All state governments are modeled after the federal government and consist of three branches (although the three-branch structure is not Constitutionally required): executive, legislative, and judicial. They retain plenary power to make laws covering anything not preempted by the U.S. Constitution, federal statutes, or treaties ratified by the U.S. Senate, and are organized as presidential systems where the governor is both head of government and head of state (even though this too is not required). The various states are then typically subdivided into counties. Louisiana uses the term parish and Alaska uses the term borough for what the Census terms county equivalents in those states.

Counties and county equivalents may be further subdivided into townships. Towns in New York, Wisconsin and New England are treated as equivalents to townships by the United States Census Bureau. Townships or towns are used as subdivisions of a county in 20 states, mostly in the Northeast and Midwest.Population centers may be organized into incorporated cities, towns, villages, and other types of municipalities. Municipalities are typically subordinate to a county government, with some exceptions. Certain cities, for example, have consolidated with their county government as consolidated city-counties. In Virginia, cities are completely independent from the county in which they would otherwise be a part. In some states, particularly in New England, towns form the primary unit of local government below the state level, in some cases eliminating the need for county government entirely.

The government of each of the five permanently inhabited U.S. territories is also modeled and organized after the federal government. Each is further subdivided into smaller entities. Puerto Rico has 78 municipalities, and the Northern Mariana Islands has 4 municipalities. Guam has villages, the U.S. Virgin Islands has districts, and American Samoa has districts and unorganized atolls.Other U.S. sub-national divisions include the District of Columbia, several minor outlying islands, and Indian reservations, all of which are administered by the Federal government. Each Indian Reservation is subdivided in various ways. For example, the Navajo Nation is subdivided into agencies and Chapter houses, while the Blackfeet Nation is subdivided into Communities. The Federal government also maintains exclusive jurisdiction over military installations and American embassies and consulates located in foreign countries. Other special purpose divisions exist separately from those for general governance, examples of which include conservation districts and Congressional districts.

According to the U.S. Internal Revenue Service,

Federal and state governments are established and recognized by the U.S. Constitution and state constitutions. Federally recognized Indian tribal governments are recognized by the U.S. Constitution, treaties, statutes and court decisions. Other entities may be recognized as governments by state law, court decision, or an examination of facts and circumstances that indicate it has the characteristics of a government, such as powers of taxation, law enforcement and civil authority.

Principal city

In the United States, a principal city is the main core city in a metropolitan area. The largest city in each metropolitan or micropolitan statistical area is designated a "principal city." Additional cities qualify if specified requirements are met concerning population size and employment. The title of each metropolitan or micropolitan statistical area consists of the names of up to three of its principal cities and the name of each state into which the metropolitan or micropolitan statistical area extends.In the United States and Puerto Rico, the Office of Management and Budget identifies principal cities for each Core Based Statistical Area (CBSA) and New England City and Town Area (NECTA). Principal cities are used primarily for naming CBSAs and NECTAs, as well as combined statistical areas and combined NECTAs.

Statistical area (United States)

The United States federal government defines and delineates the nation's metropolitan areas for statistical purposes, using a set of standard statistical area definitions. As of 2013, the U.S. Office of Management and Budget (OMB) defined and delineated 388 metropolitan statistical areas (MSAs) and 541 micropolitan statistical areas (μSAs) in the United States and Puerto Rico. Many of these 929 MSAs and μSAs are, in turn, components of larger combined statistical areas (CSAs) consisting of adjacent MSAs and μSAs that are linked by commuting ties; as of 2013, 524 metropolitan and micropolitan areas are components of the 169 defined CSAs.

Metropolitan and micropolitan statistical areas are defined as consisting of one or more adjacent counties or county equivalents with at least one urban core area meeting relevant population thresholds, plus adjacent territory that has a high degree of social and economic integration with the core, as measured by commuting ties. A metropolitan statistical area has at least one urban core with a population of at least 50,000. In a micropolitan statistical area, the largest urban core has a population of at least 10,000 but less than 50,000.

Thirteener

In mountaineering in the United States, a thirteener is a mountain that exceeds 13,000 feet (3,962.4 m) above mean sea level, similar to the more familiar "fourteeners," which exceed 14,000 feet (4,267.2 m). In most instances, "thirteeners" refers only to those peaks between 13,000 and 13,999 feet in elevation.

The importance of thirteeners is greatest in Colorado, which has the majority of such peaks in North America with over 600 of them. Despite the large number of peaks, over 20 peak baggers have reported climbing all of Colorado's thirteeners. Thirteeners are also significant in states whose highpoints fall between 13,000 and 13,999 feet. Regarding whether or not peaks in excess of 13,999 feet should be considered as "thirteeners", this article will count them as such for statistical purposes, but concentrate its focus on those peaks less than 14,000 feet since the higher peaks are already covered in the fourteeners list.

Not all summits over 13,000 feet qualify as thirteeners, but only those summits that mountaineers consider to be independent. Objective standards for independence include topographic prominence and isolation (distance from a higher summit), or a combination. However thirteener lists do not always consistently use such objective rules. A rule commonly used by mountaineers in the contiguous United States is that a peak must have at least 300 feet (91 m) of prominence to qualify. According to the Mountaineering Club of Alaska, it is standard in Alaska to use a 500 ft (152 m) prominence rule rather than a 300-foot rule. These are the standards applied for the lists below.

United States

The United States of America (USA), commonly known as the United States (U.S. or US) or America, is a country comprising 50 states, a federal district, five major self-governing territories, and various possessions. At 3.8 million square miles (9.8 million km2), the United States is the world's third or fourth largest country by total area and is slightly smaller than the entire continent of Europe's 3.9 million square miles (10.1 million km2). With a population of over 327 million people, the U.S. is the third most populous country. The capital is Washington, D.C., and the largest city by population is New York City. Forty-eight states and the capital's federal district are contiguous in North America between Canada and Mexico. The State of Alaska is in the northwest corner of North America, bordered by Canada to the east and across the Bering Strait from Russia to the west. The State of Hawaii is an archipelago in the mid-Pacific Ocean. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea, stretching across nine official time zones. The extremely diverse geography, climate, and wildlife of the United States make it one of the world's 17 megadiverse countries.Paleo-Indians migrated from Siberia to the North American mainland at least 12,000 years ago. European colonization began in the 16th century. The United States emerged from the thirteen British colonies established along the East Coast. Following the French and Indian War, numerous disputes between Great Britain and the colonies led to the American Revolution, which began in 1775, and the subsequent Declaration of Independence in 1776. The war ended in 1783 with the United States becoming the first country to gain independence from a European power. The current constitution was adopted in 1788, with the first ten amendments, collectively named the Bill of Rights, being ratified in 1791 to guarantee many fundamental civil liberties. The United States embarked on a vigorous expansion across North America throughout the 19th century, acquiring new territories, displacing Native American tribes, and gradually admitting new states until it spanned the continent by 1848.During the second half of the 19th century, the Civil War led to the abolition of slavery. By the end of the century, the United States had extended into the Pacific Ocean, and its economy, driven in large part by the Industrial Revolution, began to soar. The Spanish–American War and World War I confirmed the country's status as a global military power. The United States emerged from World War II as a global superpower, the first country to develop nuclear weapons, the only country to use them in warfare, and a permanent member of the United Nations Security Council. Sweeping civil rights legislation, notably the Civil Rights Act of 1964, the Voting Rights Act of 1965 and the Fair Housing Act of 1968, outlawed discrimination based on race or color. During the Cold War, the United States and the Soviet Union competed in the Space Race, culminating with the 1969 U.S. Moon landing. The end of the Cold War and the collapse of the Soviet Union in 1991 left the United States as the world's sole superpower.The United States is the world's oldest surviving federation. It is a federal republic and a representative democracy. The United States is a founding member of the United Nations, World Bank, International Monetary Fund, Organization of American States (OAS), and other international organizations. The United States is a highly developed country, with the world's largest economy by nominal GDP and second-largest economy by PPP, accounting for approximately a quarter of global GDP. The U.S. economy is largely post-industrial, characterized by the dominance of services and knowledge-based activities, although the manufacturing sector remains the second-largest in the world. The United States is the world's largest importer and the second largest exporter of goods, by value. Although its population is only 4.3% of the world total, the U.S. holds 31% of the total wealth in the world, the largest share of global wealth concentrated in a single country.Despite income and wealth disparities, the United States continues to rank very high in measures of socioeconomic performance, including average wage, human development, per capita GDP, and worker productivity. The United States is the foremost military power in the world, making up a third of global military spending, and is a leading political, cultural, and scientific force internationally.

United States urban area

Urban areas in the United States are defined by the U.S. Census Bureau as contiguous census block groups with a population density of at least 1,000/sq mi (390/km2) with any census block groups around this core having a density of at least 500/sq mi (190/km2). Urban areas are delineated without regard to political boundaries. The census has two distinct categories of urban areas. Urbanized Areas have populations of greater than 50,000, while Urban Clusters have populations of less than 50,000 but more than 2,500. An urbanized area may serve as the core of a metropolitan statistical area, while an urban cluster may be the core of a micropolitan statistical area.
