The Chicago metropolitan area, also colloquially referred to as Chicagoland, is a metropolitan area in the Midwestern United States. Encompassing 10,286 sq mi (28,120 km2), the metropolitan area includes the city of Chicago, its suburbs and hinterland, spanning 14 counties in northeast Illinois, northwest Indiana, and southeast Wisconsin. The MSA had a 2020 census population of 9,618,502 and the combined statistical area which spans up to 19 counties had a population of nearly 10 million people. The Chicago area is the fourth largest metropolitan area in North America (after the metro areas of Mexico City, New York City, and Los Angeles), the List of metropolitan statistical areas, third-largest metropolitan area in the United States, the largest within the entire Midwestern United States, Midwest, and the largest in the Great Lakes megalopolis. Its urban area is one of the List of urban areas by population, forty largest in the world.
According to the 2020 United States Census, 2020 Census, the metropolitan's population is approaching the 10 million mark. The metropolitan area has seen a substantial increase of Latin Americans, Latin American residents on top of its already large latin population, and the Asian American population also increased according to the 2020 Census. The metro area also has a large number of European Americans, White, African American, Black, and Arab American residents, making the Chicago metropolitan area a truly diverse region. The Chicago metropolitan area represents about 3 percent of the entire United States population.
Chicagoland, as the metropolitan area is also called, has one of the world's largest and most diversified economies. With more than six million full and part-time employees, the Chicago metropolitan area is a key factor of the Illinois economy, as the state has an annual GDP of over $1 trillion. The Chicago metropolitan area generated an annual gross regional product (GRP) of approximately $700 billion in 2018. The region is home to more than 400 major corporate headquarters, including 31 in the Fortune 500, ''Fortune'' 500 such as McDonald's, Boeing, United, and Blue Cross Blue Shield. With many companies moving to Chicagoland, the area ranked as the nation's top metropolitan area for corporation relocations for six consecutive years.
The Chicago area is home to a number of the nation's leading research universities including the University of Chicago, Northwestern University, University of Illinois at Chicago, DePaul University, Loyola University Chicago, Loyola University, and the Illinois Institute of Technology. The University of Chicago and Northwestern University are consistently ranked as two of the best universities in the world.
There are many transportation options around the area. The region has three separate rail networks: the Chicago Transit Authority (CTA) operates elevated and subway lines that run primarily throughout the city, Downtown Chicago, and into some suburbs. The CTA operates some rail lines 24 hours a day, every day of the year, nonstop service, making Chicago and New York City the only two cities in the world to offer some 24 hour rail service running nonstop, everyday throughout their city limits. The city-suburban Metra rail network runs numerous lines between Downtown Chicago and suburban/satellite cities. And the South Shore Line runs between Downtown Chicago and suburban Northwest Indiana. Amtrak operated a national rail hub at Union Station (Chicago), Union Station in Downtown Chicago.
CTA bus routes primarily serve the city proper, with some service into the suburbs. Several CTA bus routes also operate 24 hours a day, nonstop. Pace (transit), Pace bus routes primarily serve the suburbs, with some service into the city.
The Chicago Metropolitan Statistical Area was originally designated by the United States Census Bureau in 1950. It comprised the Illinois counties of Cook, DuPage, Kane, Lake and Will, along with Lake County in Indiana. As surrounding counties saw an increase in their population densities and the number of their residents employed within Cook County, they met Census criteria to be added to the MSA. The Chicago MSA, now defined as the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area, is the third largest MSA by population in the United States. The 2015 census estimate for the MSA was 9,532,569, a decline from 9,543,893 in the 2014 census estimate. This loss of population has been attributed to taxes, crime, political issues, weather, and other factors; however, a negative net migration rate statewide has been shown to be a result of poor gross in-migration, rather than an unusually high rate of gross out-migration.
The Chicago MSA is further subdivided by state boundaries into the ''Chicago-Naperville-Joliet, IL Metropolitan Division'', corresponding roughly to the CMAP region; the ''Gary, IN Metropolitan Division'' consisting of the Indiana counties of Lake and Porter, as well as two surrounding counties; and the ''Lake County-Kenosha County, IL-WI Metropolitan Division''.
A breakdown of the 2009 estimated populations of the three Metropolitan Divisions of the MSA are as follows:
* ''Chicago-Naperville-Elgin, Metropolitan Division'' (7,998,257)
** Cook County, Illinois, Cook County (5,287,037)
** DeKalb County, Illinois, DeKalb County (107,333)

Chicagoland is an informal name for the Chicago metropolitan area. The term ''Chicagoland'' has no official definition, and the region is often considered to include areas beyond the corresponding MSA, as well as portions of the greater CSA.
Robert R. McCormick, Colonel Robert R. McCormick, editor and publisher of the ''Chicago Tribune'', usually gets credit for placing the term in common use. McCormick's conception of Chicagoland stretched all the way to nearby parts of four states (Indiana, Wisconsin, Michigan, and Iowa). The first usage was in the ''Tribunes July 27, 1926 front page headline, "Chicagoland's Shrines: A Tour of Discoveries", for an article by reporter James O'Donnell Bennett. He stated that Chicagoland comprised everything in a radius in every direction and reported on many different places in the area. The ''Tribune'' was the dominant newspaper in a vast area stretching to the west of the city, and that hinterland was closely tied to the metropolis by rail lines and commercial links.
Today, the ''Chicago Tribunes usage includes the city of Chicago, the rest of Cook County, Illinois, Cook County, eight nearby Illinois counties (Lake County, Illinois, Lake, McHenry County, Illinois, McHenry, DuPage County, Illinois, DuPage, Kane County, Illinois, Kane, Kendall County, Illinois, Kendall, Grundy County, Illinois, Grundy, Will County, Illinois, Will, and Kankakee County, Illinois, Kankakee), and the two Indiana counties of Lake County, Indiana, Lake and Porter County, Indiana, Porter. Illinois Department of Tourism literature uses ''Chicagoland'' for suburbs in Cook, Lake, DuPage, Kane, and Will counties, treating the city separately. The Chicagoland Chamber of Commerce defines it as all of Cook, DuPage, Kane, Lake, McHenry, and Will counties.
In addition, company marketing programs such as Construction Data Company's "Chicago and Vicinity" region and the Chicago Automobile Trade Association's ''"Chicagoland and Northwest Indiana"'' advertising campaign are directed at the MSA itself, as well as LaSalle County, Illinois, LaSalle, Winnebago County, Illinois, Winnebago (Rockford, Illinois, Rockford), Boone County, Illinois, Boone, and Ogle County, Illinois, Ogle counties in Illinois, in addition to Jasper County, Indiana, Jasper, Newton County, Indiana, Newton, and La Porte County, Indiana, La Porte counties in Indiana and Kenosha County, Wisconsin, Kenosha, Racine County, Wisconsin, Racine, and Walworth County, Wisconsin, Walworth counties in Wisconsin, and even as far northeast as Berrien County, Michigan. The region is part of the Great Lakes Megalopolis, containing an estimated 54 million people.
As of the 2010 Census, the metropolitan area had a population of 9,729,825. The population density was 1,318 per square mile.
The racial makeup was 52.8% Non-Hispanic White, 22.1% were Hispanic, 16.7% were Non-Hispanic African Americans, and 6.4% were Asian. Other ethnic groups such as Native Americans and Pacific Islanders made up 2.0% of the population.
The suburbs, surrounded by easily annexed flat ground, have been expanding at a tremendous rate since the early 1960s. Aurora, Elgin, Joliet, and Naperville are noteworthy for being four of the few boomburbs outside the Sun Belt, West Coast of the United States, West Coast and Mountain States regions, and Commuter town, exurban Kendall County, Illinois, Kendall County ranked as the fastest-growing county (among counties with a population greater than 10,000) in the United States between the years 2000 and 2007.
Settlement patterns in the Chicago metropolitan area tend to follow those in the city proper: the northern suburbs along the shore of Lake Michigan are comparatively affluent, while the southern suburbs (sometimes known as Chicago Southland) are less so, with lower median incomes and a lower cost of living. However, there is a major exception to this. While Chicago's West Side, Chicago, West Side is the poorest section of the city, the western and northwestern suburbs contain many affluent areas. According to the 2000 Census, DuPage County, Illinois, DuPage County had the highest median household income of any county in the Midwestern United States.
According to the 2000 U.S. Census, poverty rates of the largest counties from least poverty to most are as follows: McHenry 3.70%, Dupage 5.9%, Will 6.7%, Lake 6.9%, Kane 7.4%, Cook 14.5%.
In an in-depth historical analysis, Keating (2004, 2005) examined the origins of 233 settlements that by 1900 had become suburbs or city neighborhoods of the Chicago metropolitan area. The settlements began as farm centers (41%), industrial towns (30%), residential railroad suburbs (15%), and recreational/institutional centers (13%). Although relations between the different settlement types were at times contentious, there also was cooperation in such undertakings as the construction of high schools.
The formerly distinct urban areas of Aurora, Elgin, Joliet, and Waukegan were absorbed into the Chicago UA as of the 2000 census.
† These urban areas and urban clusters are now joined to the Chicago Urban Area as of the 2010 census.

The Chicago metropolitan area is home to the corporate headquarters of 57 Fortune 1000 companies, including AbbVie Inc., Allstate, Boeing, Caterpillar Inc., Kraft Heinz, McDonald's, Mondelez International, Motorola, United Airlines, Walgreens, and List of companies in the Chicago metropolitan area, more. The Chicago area also headquarters a wide variety of global financial institutions including Citadel LLC, Discover Financial Services, Morningstar, Inc., CNA Financial, and more. Chicago is home to the largest futures exchange in the world, the Chicago Mercantile Exchange. In March 2008, the Chicago Mercantile Exchange announced its acquisition of NYMEX Holdings Inc, the parent company of the New York Mercantile Exchange and Commodity Exchange. CME'S acquisition of NYMEX was completed in August 2008.
A key piece of infrastructure for several generations was the Union Stock Yards of Chicago, which from 1865 until 1971 penned and slaughtered millions of cattle and hogs into standardized cuts of beef and pork. This prompted poet Carl Sandburg to describe Chicago as the "Hog Butcher for the World".
The Chicago area, meanwhile, began to produce significant quantities of telecommunications gear, electronics, steel, crude oil derivatives, automobiles, and industrial capital goods.
By the early 2000s, Illinois' economy had moved toward a dependence on high-value-added services, such as financial trading, higher education, logistics, and health care. In some cases, these services clustered around institutions that hearkened back to Illinois's earlier economies. For example, the Chicago Mercantile Exchange, a trading exchange for global derivative (finance), derivatives, had begun its life as an agricultural futures exchange, futures market.
In 2007, the area ranked first among U.S. metro areas in the number of new and expanded corporate facilities. It ranked third in 2008, behind the Greater Houston, Houston–Sugar Land–Baytown and Dallas–Fort Worth metropolitan areas, and ranked second behind the New York metropolitan area in 2009.
''The Wall Street Journal'' summarized the Chicago area's economy in November 2006 with the comment that "Chicago has survived by repeatedly reinventing itself."

Elementary and secondary education within the Chicago metropolitan area is provided by dozens of different school districts, of which by far the largest is the Chicago Public Schools with 400,000 students. Numerous private and religious school systems are also found in the region, as well as a growing number of charter schools. Racial inequalities in education in the region remain widespread, often breaking along district boundaries; for instance, educational prospects vary widely for students in the Chicago Public Schools compared to those in some neighboring suburban schools.
Historically, the Chicago metropolitan area has been at the center of a number of national educational movements, from the free-flowing Winnetka Plan to the regimented Taylorism of the Gary Plan. In higher education, University of Chicago founder William Rainey Harper was a leading early advocate of the junior college movement; Joliet Junior College is the nation's oldest continuously-operating junior college today. Later U of C president Robert Maynard Hutchins was central to the Great Books movement, and programs of dialogic education arising from that legacy can be found today at the U of C, at Shimer College, and in the City Colleges of Chicago and Oakton Community College in the Northwest suburbs.

Chicago Metropolitan statistical area
The Chicago Metropolitan Statistical Area was originally designated by the United States Census Bureau in 1950. It comprised the Illinois counties of Cook, DuPage, Kane, Lake and Will, along with Lake County in Indiana. As surrounding counties saw an increase in their population densities and the number of their residents employed within Cook County, they met Census criteria to be added to the MSA. The Chicago MSA, now defined as the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area, is the third largest MSA by population in the United States. The 2015 census estimate for the MSA was 9,532,569, a decline from 9,543,893 in the 2014 census estimate. This loss of population has been attributed to taxes, crime, political issues, weather, and other factors; however, a negative net migration rate statewide has been shown to be a result of poor gross in-migration, rather than an unusually high rate of gross out-migration.
The Chicago MSA is further subdivided by state boundaries into the ''Chicago-Naperville-Joliet, IL Metropolitan Division'', corresponding roughly to the CMAP region; the ''Gary, IN Metropolitan Division'' consisting of the Indiana counties of Lake and Porter, as well as two surrounding counties; and the ''Lake County-Kenosha County, IL-WI Metropolitan Division''.

Combined Statistical Area
The OMB also defines a slightly larger region as a Combined Statistical Area (CSA). The Chicago–Naperville, IL–IN–WI Combined Statistical Area combines the metropolitan areas of Chicago, Michigan City, Indiana, Michigan City (in Indiana), northeastern LaSalle County, Illinois, and Kankakee, Illinois, Kankakee (in Illinois). This area represents the extent of the labor market pool for the entire region. The CSA has a population of 9,825,325 (2019 estimate).United Nations' Chicago urban agglomeration
The Chicago urban agglomeration, according to the United Nations ''World Urbanization Prospects'' report (2018 revision), lists a population of 8,864,000. The term "urban agglomeration" refers to the population contained within the contours of a contiguous territory inhabited at urban density levels. It usually incorporates the population in a city, plus that in the contiguous urban, or built-up area.Chicagoland
Chicagoland is an informal name for the Chicago metropolitan area. The term ''Chicagoland'' has no official definition, and the region is often considered to include areas beyond the corresponding MSA, as well as portions of the greater CSA.

The region is part of the Great Lakes Megalopolis, containing an estimated 54 million people.
Collar counties
The term "collar counties" is a colloquialism for the five counties (DuPage County, Illinois, DuPage, Kane County, Illinois, Kane, Lake County, Illinois, Lake, McHenry County, Illinois, McHenry, and Will County, Illinois, Will) of Illinois that border Chicago's Cook County, Illinois, Cook County. After Cook County, they are also the next five most populous counties in the state. According to the ''Encyclopedia of Chicago'', there is no specifically known origin of the phrase, but it has been commonly used among policy makers, urban planners, and in the media. However, it also notes that as growth has spread beyond these counties, it may have lost some of its usefulness.Chicago Metropolitan Agency for Planning
Chicago Metropolitan Agency for Planning (CMAP) is an Illinois state agency responsible for transportation infrastructure, land use, and long-term economic development planning for the areas under its jurisdiction within Illinois. The planning area has a population of over 8 million, which includes the following locations in Illinois: * Cook County, Illinois, Cook County * DuPage County, Illinois, DuPage County * Kane County, Illinois, Kane County * Kendall County, Illinois, Kendall County * Lake County, Illinois, Lake County * McHenry County, Illinois, McHenry County * Will County, Illinois, Will CountyGeography and environment
The city of Chicago lies in the Chicago Plain, a flat and broad area characterized by little topographical relief. The few low hills are sand ridges. North of the Chicago Plain, steep bluffs and ravines run alongside Lake Michigan. Along the southern shore of the Chicago Plain, sand dunes run alongside the lake. The tallest dunes reach up to near and are found in Indiana Dunes National Park. Surrounding the low plain are bands of moraines in the south and west suburbs. These areas are higher and hillier than the Chicago Plain. A Chicago Portage, continental divide, separating the Mississippi River watershed from that of the Great Lakes and Saint Lawrence River, runs through the Chicago area. A 2012 survey of the urban trees and forests in the seven county Illinois section of the Chicago area found that 21% of the land is covered by the tree and shrub canopy, made up of about 157,142,000 trees. The five most common tree species are Rhamnus cathartica, buckthorn, green ash, boxelder, black cherry, and American elm. These resources perform important functions in carbon storage, water recycling, and energy saving.Demographics

Population
As the Chicago metropolitan area has grown, more counties have been partly or totally assimilated with the taking of each decennial census. Counties highlighted in gray were not included in the MSA for that census.

Elementary and secondary education within the Chicago metropolitan area is provided by dozens of different school districts, of which by far the largest is the Chicago Public Schools with 400,000 students. Numerous private and religious school systems are also found in the region, as well as a growing number of charter schools. Racial inequalities in education in the region remain widespread, often breaking along district boundaries; for instance, educational prospects vary widely for students in the Chicago Public Schools compared to those in some neighboring suburban schools.
Historically, the Chicago metropolitan area has been at the center of a number of national educational movements, from the free-flowing Winnetka Plan to the regimented Taylorism of the Gary Plan. In higher education, University of Chicago founder William Rainey Harper was a leading early advocate of the junior college movement; Joliet Junior College is the nation's oldest continuously-operating junior college today. Later U of C president Robert Maynard Hutchins was central to the Great Books movement, and programs of dialogic education arising from that legacy can be found today at the U of C, at Shimer College, and in the City Colleges of Chicago and Oakton Community College in the Northwest suburbs.
Area codes
From 1947 until 1988, the Illinois portion of the Chicago metro area was served by a single North American Numbering Plan, area code, 312, which abutted the 815 area code. In 1988 the 708 area code was introduced and the 312 area code became exclusive to the city of Chicago. It became common to call suburbanites "708'ers", in reference to their area code. The 708 area code was partitioned in 1996 into three area codes, serving different portions of the metro area: 630, 708, and 847. At the same time that the 708 area code was running out of phone numbers, the 312 area code in Chicago was also exhausting its supply of available numbers. As a result, the city of Chicago was divided into two area codes, 312 and 773. Rather than divide the city by a north–south area code, the central business district retained the 312 area code, while the remainder of the city took the new 773 code. In 2002, the 847 area code was supplemented with the overlay area code 224. In February 2007, the 815 area code (serving outlying portions of the metro area) was supplemented with the overlay area code 779. In October 2007, the overlay area code 331 was implemented to supplement the 630 area with additional numbers. Plans are in place for overlay codes in the 708, 773, and 312 regions as those area codes become exhausted in the future. * Area code 312, 312 Chicago - City (The Chicago Loop, Loop and central neighborhoods, e.g. the Near North Side) * Area code 773, 773 Chicago - City (Everywhere else within the city limits, excluding central area) * Area code 872, 872 Chicago - City (overlay for 312 & 773, effective November 7, 2009) * Area codes 847 and 224, 847/224 (North and Northwest Suburbs) * Area codes 630 and 331, 630/331 (Outer Western Suburbs) * Area code 708, 708 (South and Near West Suburbs) * Area codes 815 and 779, 815/779 (Rockford, Illinois, Rockford & Joliet, Illinois, Joliet: Far Northwest/Southwest Suburbs) * Area code 219, 219 (Northwest Indiana) * Area code 574, 574 (North-central Indiana) * Area code 262, 262 (Southeast Wisconsin surrounding Milwaukee County, Wisconsin, Milwaukee County)Proposed overlays
