In addition to its other uses, the word "area" may refer to any of the following types of country subdivisions:
Denver is the central city of a conurbation region in the U.S. state of Colorado. The conurbation includes one continuous region consisting of the six central counties of Adams, Arapahoe, Broomfield, Denver, Douglas, and Jefferson. The Denver region is part of the Front Range Urban Corridor.
A metropolitan area or metro is a region consisting of a densely populated urban core and its less-populated surrounding territories under the same administrative division, sharing industry, infrastructure and housing. A metro area usually comprises multiple jurisdictions and municipalities: neighborhoods, townships, boroughs, cities, towns, exurbs, suburbs, counties, districts, states, and even nations like the eurodistricts. As social, economic and political institutions have changed, metropolitan areas have become key economic and political regions.
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. The statistical criteria for a standard metropolitan area were defined in 1949 and redefined as metropolitan statistical area in 1983. A typical metropolitan area is centered on a single large city that wields substantial influence over the region. However, some metropolitan areas contain more than one large city with no single municipality holding a substantially dominant position. 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.
In general, a rural area or countryside is a geographic area that is located outside towns and cities. The Health Resources and Services Administration of the U.S. Department of Health and Human Services defines the word rural as encompassing "...all population, housing, and territory not included within an urban area. Whatever is not urban is considered rural."
A conurbation is a region comprising a number of metropolises, cities, large towns, and other urban areas that, through population growth and physical expansion, have merged to form one continuous urban or industrially developed area. In most cases, a conurbation is a polycentric urbanised area, in which transportation has developed to link areas to create a single urban labour market or travel to work 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 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.
The Chicago metropolitan area, or Chicagoland, is the metropolitan area of Chicago and its suburbs, covering 14 counties in the U.S. states of Illinois, Indiana, and Wisconsin. With an estimated 2019 CSA population of roughly 9.83 million people, and a MSA population of 9.46 million people, it is the third largest metropolitan area in the United States.
An urban area, or built-up area, is a human settlement with a high population density and infrastructure of built environment. Urban areas are created through urbanization and are categorized by urban morphology as cities, towns, conurbations or suburbs. In urbanism, the term contrasts to rural areas such as villages and hamlets; in urban sociology or urban anthropology it contrasts with natural environment. The creation of early predecessors of urban areas during the urban revolution led to the creation of human civilization with modern urban planning, which along with other human activities such as exploitation of natural resources led to a human impact on the environment. "Agglomeration effects" are in the list of the main consequences of increased rates of firm creation since. This is due to conditions created by a greater level of industrial activity in a given region. However, a favorable environment for human capital development would also be generated simultaneously.
United States micropolitan statistical areas, as defined by the Office of Management and Budget (OMB), are labor market and statistical areas in the United States centered on an urban cluster 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 Harrisburg–Carlisle, Pennsylvania, metropolitan statistical area is defined by the United States Census Bureau as an area consisting of three counties in Pennsylvania's Susquehanna Valley, anchored by the cities of Harrisburg and Carlisle.

The metropolitan areas of Mexico have been traditionally defined as the group of municipalities that heavily interact with each other, usually around a core city.
The North Central Colorado Urban Area comprises the four contiguous metropolitan statistical areas in the north central region of the State of Colorado: the Denver-Aurora Metropolitan Statistical Area, the Boulder Metropolitan Statistical Area, the Fort Collins-Loveland Metropolitan Statistical Area, and the Greeley Metropolitan Statistical Area. With the exception of southeastern Elbert County, southeastern Park County, and tiny portions of southern Douglas County, the entire North Central Colorado Urban Area is drained by the South Platte River and its tributaries. The North Central Colorado Urban Area is the central, and the most populous, of the three primary subregions of the Front Range Urban Corridor.
The statistical areas of the United States of America comprise the metropolitan statistical areas (MSAs), the micropolitan statistical areas (μSAs), and the combined statistical areas (CSAs) currently defined by the United States Office of Management and Budget (OMB).
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. A collective term for MSAs, μSAs, and CSAs is primary statistical areas (PSAs).
The Front Range Urban Corridor is an oblong region of urban population located along the eastern face of the Southern Rocky Mountains, encompassing 18 counties in the US states of Colorado and Wyoming. The corridor derives its name from the Front Range, the mountain range that defines the western boundary of the corridor which serves as a gateway to the Rocky Mountains. The region comprises the northern portion of the Southern Rocky Mountain Front geographic area, which in turn comprises the southern portion of the Rocky Mountain Front geographic area of Canada and the United States. The Front Range Urban Corridor had an estimated population of 4,976,781 on July 1, 2018, an increase of +14.84% since the 2010 United States Census.. It is estimated that the population exceeded 5 million in 2019. Roughly 98% of the population within the entire urban corridor region is within Colorado and roughly 85% of Colorado's population resides within the urban corridor region.
