In the mid-18th century, the area was inhabited by the Potawatomi, a Native American tribe who had succeeded the Miami and Sauk and Fox peoples in this region.[21]

The first known permanent settler in Chicago was trader Jean Baptiste Point du Sable. Du Sable was of African descent, perhaps born in the French colony of Saint-Domingue (Haiti), and established the settlement in the 1780s. He is commonly known as the "Founder of Chicago".[22][23][24]

In 1795, following the victory of the new United States in the Northwest Indian War, an area that was to be part of Chicago was turned over to the US for a military post by native tribes in accordance with the Treaty of Greenville. In 1803, the U.S. Army constructed Fort Dearborn, which was destroyed during the War of 1812 in the Battle of Fort Dearborn by the Potawatomi before being later rebuilt.[25]

After the War of 1812, the Ottawa, Ojibwe, and Potawatomi tribes ceded additional land to the United States in the 1816 Treaty of St. Louis. The Potawatomi were forcibly removed from their land after the 1833 Treaty of Chicago and sent west of the Mississippi River as part of the federal policy of Indian removal.[26][27][28]

On August 12, 1833, the Town of Chicago was organized with a population of about 200.[28] Within seven years it grew to more than 6,000 people. On June 15, 1835, the first public land sales began with Edmund Dick Taylor as Receiver of Public Monies. The City of Chicago was incorporated on Saturday, March 4, 1837,[29] and for several decades was the world's fastest-growing city.[30]

As the site of the Chicago Portage,[31] the city became an important transportation hub between the eastern and western United States. Chicago's first railway, Galena and Chicago Union Railroad, and the Illinois and Michigan Canal opened in 1848. The canal allowed steamboats and sailing ships on the Great Lakes to connect to the Mississippi River.[32][33][34][35]

A flourishing economy brought residents from rural communities and immigrants from abroad. Manufacturing and retail and finance sectors became dominant, influencing the American economy.[36] The Chicago Board of Trade (established 1848) listed the first-ever standardized "exchange-traded" forward contracts, which were called futures contracts.[37]

In the 1850s, Chicago gained national political prominence as the home of Senator Stephen Douglas, the champion of the Kansas–Nebraska Act and the "popular sovereignty" approach to the issue of the spread of slavery.[38] These issues also helped propel another Illinoisan, Abraham Lincoln, to the national stage. Lincoln was nominated in Chicago for US president at the 1860 Republican National Convention, which was held in a purpose-built auditorium called the Wigwam. He defeated Douglas in the general election, and this set the stage for the American Civil War.

To accommodate rapid population growth and demand for better sanitation, the city improved its infrastructure. In February 1856, Chicago's Common Council approved Chesbrough's plan to build the United States' first comprehensive sewerage system.[39] The project raised much of central Chicago to a new grade with the use of jackscrews for raising buildings.[40] While elevating Chicago, and at first improving the city's health, the untreated sewage and industrial waste now flowed into the Chicago River, and subsequently into Lake Michigan, polluting the city's primary freshwater source.

The city responded by tunneling two miles (3.2 km) out into Lake Michigan to newly built water cribs. In 1900, the problem of sewage contamination was largely resolved when the city completed a major engineering feat. It reversed the flow of the Chicago River so that the water flowed away from Lake Michigan rather than into it. This project began with the construction and improvement of the Illinois and Michigan Canal, and was completed with the Chicago Sanitary and Ship Canal that connects to the Illinois River, which flows into the Mississippi River.[41][42][43]

In 1871, the Great Chicago Fire destroyed an area about 4 miles (6.4 km) long and 1-mile (1.6 km) wide, a large section of the city at the time.[44][45][46] Much of the city, including railroads and stockyards, survived intact,[47] and from the ruins of the previous wooden structures arose more modern constructions of steel and stone. These set a precedent for worldwide construction.[48][49] During its rebuilding period, Chicago constructed the world's first skyscraper in 1885, using steel-skeleton construction.[50][51]

The city grew significantly in size and population by incorporating many neighboring townships between 1851 and 1920, with the largest annexation happening in 1889, with five townships joining the city, including the Hyde Park Township, which now comprises most of the South Side of Chicago and the far southeast of Chicago, and the Jefferson Township, which now makes up most of Chicago's Northwest Side.[52] The desire to join the city was driven by municipal services that the city could provide its residents.

Chicago's flourishing economy attracted huge numbers of new immigrants from Europe and migrants from the Eastern United States. Of the total population in 1900, more than 77% were either foreign-born or born in the United States of foreign parentage. Germans, Irish, Poles, Swedes, and Czechs made up nearly two-thirds of the foreign-born population (by 1900, whites were 98.1% of the city's population).[53][54]

Labor conflicts followed the industrial boom and the rapid expansion of the labor pool, including the Haymarket affair on May 4, 1886, and in 1894 the Pullman Strike. Anarchist and socialist groups played prominent roles in creating very large and highly organized labor actions. Concern for social problems among Chicago's immigrant poor led Jane Addams and Ellen Gates Starr to found Hull House in 1889.[55] Programs that were developed there became a model for the new field of social work.[56]

During the 1870s and 1880s, Chicago attained national stature as the leader in the movement to improve public health. City laws and later, state laws that upgraded standards for the medical profession and fought urban epidemics of cholera, smallpox, and yellow fever were both passed and enforced. These laws became templates for public health reform in other cities and states.[57]

The city established many large, well-landscaped municipal parks, which also included public sanitation facilities. The chief advocate for improving public health in Chicago was John H. Rauch, M.D. Rauch established a plan for Chicago's park system in 1866. He created Lincoln Park by closing a cemetery filled with shallow graves, and in 1867, in response to an outbreak of cholera he helped establish a new Chicago Board of Health. Ten years later, he became the secretary and then the president of the first Illinois State Board of Health, which carried out most of its activities in Chicago.[58]

In the 1800s, Chicago became the nation's railroad hub, and by 1910 over 20 railroads operated passenger service out of six different downtown terminals.[59][60] In 1883, Chicago's railway managers needed a general time convention, so they developed the standardized system of North American time zones.[61] This system for telling time spread throughout the continent.

In 1893, Chicago hosted the World's Columbian Exposition on former marshland at the present location of Jackson Park. The Exposition drew 27.5 million visitors, and is considered the most influential world's fair in history.[62][63] The University of Chicago, formerly at another location, moved to the same South Side location in 1892. The term "midway" for a fair or carnival referred originally to the Midway Plaisance, a strip of park land that still runs through the University of Chicago campus and connects the Washington and Jackson Parks.[64][65]

During World War I and the 1920s there was a major expansion in industry. The availability of jobs attracted African Americans from the Southern United States. Between 1910 and 1930, the African American population of Chicago increased dramatically, from 44,103 to 233,903.[66] This Great Migration had an immense cultural impact, called the Chicago Black Renaissance, part of the New Negro Movement, in art, literature, and music.[67] Continuing racial tensions and violence, such as the Chicago race riot of 1919, also occurred.[68]

The ratification of the 18th amendment to the Constitution in 1919 made the production and sale (including exportation) of alcoholic beverages illegal in the United States. This ushered in the beginning of what is known as the gangster era, a time that roughly spans from 1919 until 1933 when Prohibition was repealed. The 1920s saw gangsters, including Al Capone, Dion O'Banion, Bugs Moran and Tony Accardo battle law enforcement and each other on the streets of Chicago during the Prohibition era.[69] Chicago was the location of the infamous St. Valentine's Day Massacre in 1929, when Al Capone sent men to gun down members of a rival gang, North Side, led by Bugs Moran.[70]

Chicago was the first American city to have a homosexual-rights organization. The organization, formed in 1924, was called the Society for Human Rights. It produced the first American publication for homosexuals, Friendship and Freedom. Police and political pressure caused the organization to disband.[71]

The Great Depression brought unprecedented suffering to Chicago, in no small part due to the city's heavy reliance on heavy industry. Notably, industrial areas on the south side and neighborhoods lining both branches of the Chicago River were devastated; by 1933 over 50% of industrial jobs in the city had been lost, and unemployment rates amongst blacks and Mexicans in the city were over 40%. The Republican political machine in Chicago was utterly destroyed by the economic crisis, and every mayor since 1931 has been a Democrat.[72]

From 1928 to 1933, the city witnessed a tax revolt, and the city was unable to meet payroll or provide relief efforts. The fiscal crisis was resolved by 1933, and at the same time, federal relief funding began to flow into Chicago.[72] Chicago was also a hotbed of labor activism, with Unemployed Councils contributing heavily in the early depression to create solidarity for the poor and demand relief, these organizations were created by socialist and communist groups. By 1935 the Workers Alliance of America begun organizing the poor, workers, the unemployed. In the spring of 1937 Republic Steel Works witnessed the Memorial Day massacre of 1937 in the neighborhood of East Side.

In 1933, Chicago Mayor Anton Cermak was fatally wounded in Miami, Florida, during a failed assassination attempt on President-elect Franklin D. Roosevelt. In 1933 and 1934, the city celebrated its centennial by hosting the Century of Progress International Exposition World's Fair.[73] The theme of the fair was technological innovation over the century since Chicago's founding.[74]

Boy from Chicago, 1941

The Chicago Picasso (1967) inspired a new era in urban public art.

During World War II, the city of Chicago alone produced more steel than the United Kingdom every year from 1939 – 1945, and more than Nazi Germany from 1943 – 1945.[75]

The Great Migration, which had been on pause due to the Depression, resumed at an even faster pace in the second wave, as hundreds of thousands of blacks from the South arrived in the city to work in the steel mills, railroads, and shipping yards.[76]

On December 2, 1942, physicist Enrico Fermi conducted the world's first controlled nuclear reaction at the University of Chicago as part of the top-secret Manhattan Project. This led to the creation of the atomic bomb by the United States, which it used in World War II in 1945.[77]

Mayor Richard J. Daley, a Democrat, was elected in 1955, in the era of machine politics. In 1956, the city conducted its last major expansion when it annexed the land under O'Hare airport, including a small portion of DuPage County.[78]

By the 1960s, white residents in several neighborhoods left the city for the suburban areas – in many American cities, a process known as white flight – as Blacks continued to move beyond the Black Belt.[79] While home loan discriminatory redlining against blacks continued, the real estate industry practiced what became known as blockbusting, completely changing the racial composition of whole neighborhoods.[80] Structural changes in industry, such as globalization and job outsourcing, caused heavy job losses for lower-skilled workers. At its peak during the 1960s, some 250,000 workers were employed in the steel industry in Chicago, but the steel crisis of the 1970s and 1980s reduced this number to just 28,000 in 2015. In 1966, Martin Luther King Jr. and Albert Raby led the Chicago Freedom Movement, which culminated in agreements between Mayor Richard J. Daley and the movement leaders.[81]

Two years later, the city hosted the tumultuous 1968 Democratic National Convention, which featured physical confrontations both inside and outside the convention hall, with anti-war protesters, journalists and bystanders being beaten by police.[82] Major construction projects, including the Sears Tower (now known as the Willis Tower, which in 1974 became the world's tallest building), University of Illinois at Chicago, McCormick Place, and O'Hare International Airport, were undertaken during Richard J. Daley's tenure.[83] In 1979, Jane Byrne, the city's first female mayor, was elected. She was notable for temporarily moving into the crime-ridden Cabrini-Green housing project and for leading Chicago's school system out of a financial crisis.[84]

In 1983, Harold Washington became the first black mayor of Chicago. Washington's first term in office directed attention to poor and previously neglected minority neighborhoods. He was re‑elected in 1987 but died of a heart attack soon after.[85] Washington was succeeded by 6th ward alderman Eugene Sawyer, who was elected by the Chicago City Council and served until a special election.

Richard M. Daley, son of Richard J. Daley, was elected in 1989. His accomplishments included improvements to parks and creating incentives for sustainable development, as well as closing Meigs Field in the middle of the night and destroying the runways. After successfully running for re-election five times, and becoming Chicago's longest-serving mayor, Richard M. Daley declined to run for a seventh term.[86][87]

In 1992, a construction accident near the Kinzie Street Bridge produced a breach connecting the Chicago River to a tunnel below, which was part of an abandoned freight tunnel system extending throughout the downtown Loop district. The tunnels filled with 250 million US gallons (1,000,000 m³) of water, affecting buildings throughout the district and forcing a shutdown of electrical power.[88] The area was shut down for three days and some buildings did not reopen for weeks; losses were estimated at $1.95 billion.[88]

On February 23, 2011, Rahm Emanuel, a former White House Chief of Staff and member of the House of Representatives, won the mayoral election.[89] Emanuel was sworn in as mayor on May 16, 2011, and won re-election in 2015.[90] Lori Lightfoot, the city's first African American woman mayor and its first openly LGBTQ mayor, was elected to succeed Emanuel as mayor in 2019.[91] All three city-wide elective offices were held by women (and women of color) for the first time in Chicago history: in addition to Lightfoot, the city clerk was Anna Valencia and the city treasurer was Melissa Conyears-Ervin.[92]

On May 15, 2023, Brandon Johnson assumed office as the 57th mayor of Chicago.

Downtown and the North Side with beaches lining the waterfront

Chicago is located in northeastern Illinois on the southwestern shores of freshwater Lake Michigan. It is the principal city in the Chicago metropolitan area, situated in both the Midwestern United States and the Great Lakes region. The city rests on a continental divide at the site of the Chicago Portage, connecting the Mississippi River and the Great Lakes watersheds. In addition to it lying beside Lake Michigan, two rivers—the Chicago River in downtown and the Calumet River in the industrial far South Side—flow either entirely or partially through the city.[93][94]

Chicago's history and economy are closely tied to its proximity to Lake Michigan. While the Chicago River historically handled much of the region's waterborne cargo, today's huge lake freighters use the city's Lake Calumet Harbor on the South Side. The lake also provides another positive effect: moderating Chicago's climate, making waterfront neighborhoods slightly warmer in winter and cooler in summer.[95]

When Chicago was founded in 1837, most of the early building was around the mouth of the Chicago River, as can be seen on a map of the city's original 58 blocks.[96] The overall grade of the city's central, built-up areas is relatively consistent with the natural flatness of its overall natural geography, generally exhibiting only slight differentiation otherwise. The average land elevation is 579 ft (176.5 m) above sea level. While measurements vary somewhat,[97] the lowest points are along the lake shore at 578 ft (176.2 m), while the highest point, at 672 ft (205 m), is the morainal ridge of Blue Island in the city's far south side.[98]

Lake Shore Drive runs adjacent to a large portion of Chicago's waterfront. Some of the parks along the waterfront include Lincoln Park, Grant Park, Burnham Park, and Jackson Park. There are 24 public beaches across 26 miles (42 km) of the waterfront.[99] Landfill extends into portions of the lake providing space for Navy Pier, Northerly Island, the Museum Campus, and large portions of the McCormick Place Convention Center. Most of the city's high-rise commercial and residential buildings are close to the waterfront.

An informal name for the entire Chicago metropolitan area is "Chicagoland", which generally means the city and all its suburbs, though different organizations have slightly different definitions.[100][101][102]

Community areas of Chicago

Major sections of the city include the central business district, called The Loop, and the North, South, and West Sides.[103] The three sides of the city are represented on the Flag of Chicago by three horizontal white stripes.[104] The North Side is the most-densely-populated residential section of the city, and many high-rises are located on this side of the city along the lakefront.[105] The South Side is the largest section of the city, encompassing roughly 60% of the city's land area. The South Side contains most of the facilities of the Port of Chicago.[106]

In the late-1920s, sociologists at the University of Chicago subdivided the city into 77 distinct community areas, which can further be subdivided into over 200 informally defined neighborhoods.[107][108]

Chicago's streets were laid out in a street grid that grew from the city's original townsite plot, which was bounded by Lake Michigan on the east, North Avenue on the north, Wood Street on the west, and 22nd Street on the south.[109] Streets following the Public Land Survey System section lines later became arterial streets in outlying sections. As new additions to the city were platted, city ordinance required them to be laid out with eight streets to the mile in one direction and sixteen in the other direction, about one street per 200 meters in one direction and one street per 100 meters in the other direction. The grid's regularity provided an efficient means of developing new real estate property. A scattering of diagonal streets, many of them originally Native American trails, also cross the city (Elston, Milwaukee, Ogden, Lincoln, etc.). Many additional diagonal streets were recommended in the Plan of Chicago, but only the extension of Ogden Avenue was ever constructed.[110]

In 2016, Chicago was ranked the sixth-most walkable large city in the United States.[111] Many of the city's residential streets have a wide patch of grass or trees between the street and the sidewalk itself. This helps to keep pedestrians on the sidewalk further away from the street traffic. Chicago's Western Avenue is the longest continuous urban street in the world.[112] Other notable streets include Michigan Avenue, State Street, Oak, Rush, Clark Street, and Belmont Avenue. The City Beautiful movement inspired Chicago's boulevards and parkways.[113]

The Chicago Building (1904–05) is a prime example of the Chicago School, displaying both variations of the Chicago window.

The destruction caused by the Great Chicago Fire led to the largest building boom in the history of the nation. In 1885, the first steel-framed high-rise building, the Home Insurance Building, rose in the city as Chicago ushered in the skyscraper era,[51] which would then be followed by many other cities around the world.[114] Today, Chicago's skyline is among the world's tallest and densest.[115]

Some of the United States' tallest towers are located in Chicago; Willis Tower (formerly Sears Tower) is the second tallest building in the Western Hemisphere after One World Trade Center, and Trump International Hotel and Tower is the third tallest in the country.[116] The Loop's historic buildings include the Chicago Board of Trade Building, the Fine Arts Building, 35 East Wacker, and the Chicago Building, 860-880 Lake Shore Drive Apartments by Mies van der Rohe. Many other architects have left their impression on the Chicago skyline such as Daniel Burnham, Louis Sullivan, Charles B. Atwood, John Root, and Helmut Jahn.[117][118]

The Merchandise Mart, once first on the list of largest buildings in the world, currently listed as 44th-largest (as of 9 September 2013), had its own zip code until 2008, and stands near the junction of the North and South branches of the Chicago River.[119] Presently, the four tallest buildings in the city are Willis Tower (formerly the Sears Tower, also a building with its own zip code), Trump International Hotel and Tower, the Aon Center (previously the Standard Oil Building), and the John Hancock Center. Industrial districts, such as some areas on the South Side, the areas along the Chicago Sanitary and Ship Canal, and the Northwest Indiana area are clustered.[120]

Chicago gave its name to the Chicago School and was home to the Prairie School, two movements in architecture.[121] Multiple kinds and scales of houses, townhouses, condominiums, and apartment buildings can be found throughout Chicago. Large swaths of the city's residential areas away from the lake are characterized by brick bungalows built from the early 20th century through the end of World War II. Chicago is also a prominent center of the Polish Cathedral style of church architecture. The Chicago suburb of Oak Park was home to famous architect Frank Lloyd Wright, who had designed The Robie House located near the University of Chicago.[122][123]

A popular tourist activity is to take an architecture boat tour along the Chicago River.[124]

Chicago is famous for its outdoor public art with donors establishing funding for such art as far back as Benjamin Ferguson's 1905 trust.[125] A number of Chicago's public art works are by modern figurative artists. Among these are Chagall's Four Seasons; the Chicago Picasso; Miro's Chicago; Calder's Flamingo; Oldenburg's Batcolumn; Moore's Large Interior Form, 1953-54, Man Enters the Cosmos and Nuclear Energy; Dubuffet's Monument with Standing Beast, Abakanowicz's Agora; and, Anish Kapoor's Cloud Gate which has become an icon of the city. Some events which shaped the city's history have also been memorialized by art works, including the Great Northern Migration (Saar) and the centennial of statehood for Illinois. Finally, two fountains near the Loop also function as monumental works of art: Plensa's Crown Fountain as well as Burnham and Bennett's Buckingham Fountain.[126][127]

The Chicago River during the January 2014 cold wave

The city lies within the typical hot-summer humid continental climate (Köppen: Dfa), and experiences four distinct seasons.[128][129][130] Summers are hot and humid, with frequent heat waves. The July daily average temperature is 75.4 °F (24.1 °C), with afternoon temperatures peaking at 84.5 °F (29.2 °C). In a normal summer, temperatures reach at least 90 °F (32 °C) on 17 days, with lakefront locations staying cooler when winds blow off the lake. Winters are relatively cold and snowy. Blizzards do occur, such as in winter 2011.[131] There are many sunny but cold days. The normal winter high from December through March is about 36 °F (2 °C). January and February are the coldest months. A polar vortex in January 2019 nearly broke the city's cold record of −27 °F (−33 °C), which was set on January 20, 1985.[132][133][134] Measurable snowfall can continue through the first or second week of April.[135]

Spring and autumn are mild, short seasons, typically with low humidity. Dew point temperatures in the summer range from an average of 55.8 °F (13.2 °C) in June to 61.7 °F (16.5 °C) in July.[136] They can reach nearly 80 °F (27 °C), such as during the July 2019 heat wave. The city lies within USDA plant hardiness zone 6a, transitioning to 5b in the suburbs.[137]

According to the National Weather Service, Chicago's highest official temperature reading of 105 °F (41 °C) was recorded on July 24, 1934.[138] Midway Airport reached 109 °F (43 °C) one day prior and recorded a heat index of 125 °F (52 °C) during the 1995 heatwave.[139] The lowest official temperature of −27 °F (−33 °C) was recorded on January 20, 1985, at O'Hare Airport.[136][139] Most of the city's rainfall is brought by thunderstorms, averaging 38 a year. The region is prone to severe thunderstorms during the spring and summer which can produce large hail, damaging winds, and occasionally tornadoes.[140]

Like other major cities, Chicago experiences an urban heat island, making the city and its suburbs milder than surrounding rural areas, especially at night and in winter. The proximity to Lake Michigan tends to keep the Chicago lakefront somewhat cooler in summer and less brutally cold in winter than inland parts of the city and suburbs away from the lake.[141] Northeast winds from wintertime cyclones departing south of the region sometimes bring the city lake-effect snow.[142]

As in the rest of the state of Illinois, Chicago forms part of the Central Time Zone. The border with the Eastern Time Zone is located a short distance to the east, used in Michigan and certain parts of Indiana.

According to a 2014 study by the Pew Research Center, Christianity is the most prevalently practiced religion in Chicago (71%),[176] with the city being the fourth-most religious metropolis in the United States after Dallas, Atlanta and Houston.[176] Roman Catholicism and Protestantism are the largest branches (34% and 35% respectively), followed by Eastern Orthodoxy and Jehovah's Witnesses with 1% each.[175] Chicago also has a sizable non-Christian population. Non-Christian groups include Irreligious (22%), Judaism (3%), Islam (2%), Buddhism (1%) and Hinduism (1%).[175]

Chicago is the headquarters of several religious denominations, including the Evangelical Covenant Church and the Evangelical Lutheran Church in America. It is the seat of several dioceses. The Fourth Presbyterian Church is one of the largest Presbyterian congregations in the United States based on memberships.[177] Since the 20th century Chicago has also been the headquarters of the Assyrian Church of the East.[178] In 2014 the Catholic Church was the largest individual Christian denomination (34%), with the Roman Catholic Archdiocese of Chicago being the largest Catholic jurisdiction. Evangelical Protestantism form the largest theological Protestant branch (16%), followed by Mainline Protestants (11%), and historically Black churches (8%). Among denominational Protestant branches, Baptists formed the largest group in Chicago (10%); followed by Nondenominational (5%); Lutherans (4%); and Pentecostals (3%).[175]

Non-Christian faiths accounted for 7% of the religious population in 2014. Judaism has at least 261,000 adherents which is 3% of the population, making it the second largest religion.[179][175] A 2020 study estimated the total Jewish population of the Chicago metropolitan area, both religious and irreligious, at 319,600.[180]

The first two Parliament of the World's Religions in 1893 and 1993 were held in Chicago.[181] Many international religious leaders have visited Chicago, including Mother Teresa, the Dalai Lama[182] and Pope John Paul II in 1979.[183]

Renowned Chicago theater companies include the Goodman Theatre in the Loop; the Steppenwolf Theatre Company and Victory Gardens Theater in Lincoln Park; and the Chicago Shakespeare Theater at Navy Pier. Broadway In Chicago offers Broadway-style entertainment at five theaters: the Nederlander Theatre, CIBC Theatre, Cadillac Palace Theatre, Auditorium Building of Roosevelt University, and Broadway Playhouse at Water Tower Place. Polish language productions for Chicago's large Polish speaking population can be seen at the historic Gateway Theatre in Jefferson Park. Since 1968, the Joseph Jefferson Awards are given annually to acknowledge excellence in theater in the Chicago area. Chicago's theater community spawned modern improvisational theater, and includes the prominent groups The Second City and I.O. (formerly ImprovOlympic).

The Chicago Symphony Orchestra (CSO) performs at Symphony Center, and is recognized as one of the best orchestras in the world.[208] Also performing regularly at Symphony Center is the Chicago Sinfonietta, a more diverse and multicultural counterpart to the CSO. In the summer, many outdoor concerts are given in Grant Park and Millennium Park. Ravinia Festival, located 25 miles (40 km) north of Chicago, is the summer home of the CSO, and is a favorite destination for many Chicagoans. The Civic Opera House is home to the Lyric Opera of Chicago.[209] The Lithuanian Opera Company of Chicago was founded by Lithuanian Chicagoans in 1956,[210] and presents operas in Lithuanian.

The Joffrey Ballet and Chicago Festival Ballet perform in various venues, including the Harris Theater in Millennium Park. Chicago has several other contemporary and jazz dance troupes, such as the Hubbard Street Dance Chicago and Chicago Dance Crash.

Other live-music genre which are part of the city's cultural heritage include Chicago blues, Chicago soul, jazz, and gospel. The city is the birthplace of house music (a popular form of electronic dance music) and industrial music, and is the site of an influential hip hop scene. In the 1980s and 90s, the city was the global center for house and industrial music, two forms of music created in Chicago, as well as being popular for alternative rock, punk, and new wave. The city has been a center for rave culture, since the 1980s. A flourishing independent rock music culture brought forth Chicago indie. Annual festivals feature various acts, such as Lollapalooza and the Pitchfork Music Festival. Lollapalooza originated in Chicago in 1991 and at first travelled to many cities, but as of 2005 its home has been Chicago.[211] A 2007 report on the Chicago music industry by the University of Chicago Cultural Policy Center ranked Chicago third among metropolitan U.S. areas in "size of music industry" and fourth among all U.S. cities in "number of concerts and performances".[212]

Chicago has a distinctive fine art tradition. For much of the twentieth century, it nurtured a strong style of figurative surrealism, as in the works of Ivan Albright and Ed Paschke. In 1968 and 1969, members of the Chicago Imagists, such as Roger Brown, Leon Golub, Robert Lostutter, Jim Nutt, and Barbara Rossi produced bizarre representational paintings. Henry Darger is one of the most celebrated figures of outsider art.[213]

Ferries offer sightseeing tours and water-taxi transportation along the Chicago River and Lake Michigan.

Magnificent Mile hosts numerous upscale stores and landmarks, including the Chicago Water Tower.

In 2014, Chicago attracted 50.17 million domestic leisure travelers, 11.09 million domestic business travelers and 1.308 million overseas visitors.[214] These visitors contributed more than US$13.7 billion to Chicago's economy.[214] Upscale shopping along the Magnificent Mile and State Street, thousands of restaurants, as well as Chicago's eminent architecture, continue to draw tourists. The city is the United States' third-largest convention destination. A 2017 study by Walk Score ranked Chicago the sixth-most walkable of fifty largest cities in the United States.[215] Most conventions are held at McCormick Place, just south of Soldier Field. Navy Pier, located just east of Streeterville, is 3,000 ft (910 m) long and houses retail stores, restaurants, museums, exhibition halls and auditoriums. Chicago was the first city in the world to ever erect a ferris wheel. The Willis Tower (formerly named Sears Tower) is a popular destination for tourists.[216]

Among the city's museums are the Adler Planetarium & Astronomy Museum, the Field Museum of Natural History, and the Shedd Aquarium. The Museum Campus joins the southern section of Grant Park, which includes the renowned Art Institute of Chicago. Buckingham Fountain anchors the downtown park along the lakefront. The University of Chicago's Institute for the Study of Ancient Cultures, West Asia & North Africa has an extensive collection of ancient Egyptian and Near Eastern archaeological artifacts. Other museums and galleries in Chicago include the Chicago History Museum, the Driehaus Museum, the DuSable Museum of African American History, the Museum of Contemporary Art, the Peggy Notebaert Nature Museum, the Polish Museum of America, the Museum of Broadcast Communications, the Pritzker Military Library, the Chicago Architecture Foundation, and the Museum of Science and Industry.

Chicago-style deep-dish pizza

Chicago lays claim to a large number of regional specialties that reflect the city's ethnic and working-class roots. Included among these are its nationally renowned deep-dish pizza; this style is said to have originated at Pizzeria Uno.[217] The Chicago-style thin crust is also popular in the city.[218] Certain Chicago pizza favorites include Lou Malnati's and Giordano's.[219]

The Chicago-style hot dog, typically an all-beef hot dog, is loaded with an array of toppings that often includes pickle relish, yellow mustard, pickled sport peppers, tomato wedges, dill pickle spear and topped off with celery salt on a poppy seed bun.[220] Enthusiasts of the Chicago-style hot dog frown upon the use of ketchup as a garnish, but may prefer to add giardiniera.[221][222][223]

A distinctly Chicago sandwich, the Italian beef sandwich is thinly sliced beef simmered in au jus and served on an Italian roll with sweet peppers or spicy giardiniera. A popular modification is the Combo—an Italian beef sandwich with the addition of an Italian sausage. The Maxwell Street Polish is a grilled or deep-fried kielbasa—on a hot dog roll, topped with grilled onions, yellow mustard, and hot sport peppers.[224]

Chicken Vesuvio is roasted bone-in chicken cooked in oil and garlic next to garlicky oven-roasted potato wedges and a sprinkling of green peas. The Puerto Rican-influenced jibarito is a sandwich made with flattened, fried green plantains instead of bread. The mother-in-law is a tamale topped with chili and served on a hot dog bun.[225] The tradition of serving the Greek dish saganaki while aflame has its origins in Chicago's Greek community.[226] The appetizer, which consists of a square of fried cheese, is doused with Metaxa and flambéed table-side.[227] Chicago-style barbecue features hardwood smoked rib tips and hot links which were traditionally cooked in an aquarium smoker, a Chicago invention.[228] Annual festivals feature various Chicago signature dishes, such as Taste of Chicago and the Chicago Food Truck Festival.[229]

One of the world's most decorated restaurants and a recipient of three Michelin stars, Alinea is located in Chicago. Well-known chefs who have had restaurants in Chicago include: Charlie Trotter, Rick Tramonto, Grant Achatz, and Rick Bayless. In 2003, Robb Report named Chicago the country's "most exceptional dining destination".[230]

Carl Sandburg's most famous description of the city is as "Hog Butcher for the World / Tool Maker, Stacker of Wheat / Player with Railroads and the Nation's Freight Handler, / Stormy, Husky, Brawling, City of the Big Shoulders."

Chicago literature finds its roots in the city's tradition of lucid, direct journalism, lending to a strong tradition of social realism. In the Encyclopedia of Chicago, Northwestern University Professor Bill Savage describes Chicago fiction as prose which tries to "capture the essence of the city, its spaces and its people". The challenge for early writers was that Chicago was a frontier outpost that transformed into a global metropolis in the span of two generations. Narrative fiction of that time, much of it in the style of "high-flown romance" and "genteel realism", needed a new approach to describe the urban social, political, and economic conditions of Chicago.[231] Nonetheless, Chicagoans worked hard to create a literary tradition that would stand the test of time,[232] and create a "city of feeling" out of concrete, steel, vast lake, and open prairie.[233] Much notable Chicago fiction focuses on the city itself, with social criticism keeping exultation in check.

At least three short periods in the history of Chicago have had a lasting influence on American literature.[234] These include from the time of the Great Chicago Fire to about 1900, what became known as the Chicago Literary Renaissance in the 1910s and early 1920s, and the period of the Great Depression through the 1940s.

What would become the influential Poetry magazine was founded in 1912 by Harriet Monroe, who was working as an art critic for the Chicago Tribune. The magazine discovered such poets as Gwendolyn Brooks, James Merrill, and John Ashbery.[235] T. S. Eliot's first professionally published poem, "The Love Song of J. Alfred Prufrock", was first published by Poetry. Contributors have included Ezra Pound, William Butler Yeats, William Carlos Williams, Langston Hughes, and Carl Sandburg, among others. The magazine was instrumental in launching the Imagist and Objectivist poetic movements. From the 1950s through 1970s, American poetry continued to evolve in Chicago.[236] In the 1980s, a modern form of poetry performance began in Chicago, the poetry slam.[237]

The government of the City of Chicago is divided into executive and legislative branches. The mayor of Chicago is the chief executive, elected by general election for a term of four years, with no term limits. The current mayor is Brandon Johnson. The mayor appoints commissioners and other officials who oversee the various departments. As well as the mayor, Chicago's clerk and treasurer are also elected citywide. The City Council is the legislative branch and is made up of 50 aldermen, one elected from each ward in the city.[260] The council takes official action through the passage of ordinances and resolutions and approves the city budget.[261]

The Chicago Police Department provides law enforcement and the Chicago Fire Department provides fire suppression and emergency medical services for the city and its residents. Civil and criminal law cases are heard in the Cook County Circuit Court of the State of Illinois court system, or in the Northern District of Illinois, in the federal system. In the state court, the public prosecutor is the Illinois state's attorney; in the Federal court it is the United States attorney.

During much of the last half of the 19th century, Chicago's politics were dominated by a growing Democratic Party organization. During the 1880s and 1890s, Chicago had a powerful radical tradition with large and highly organized socialist, anarchist and labor organizations.[263] For much of the 20th century, Chicago has been among the largest and most reliable Democratic strongholds in the United States; with Chicago's Democratic vote the state of Illinois has been "solid blue" in presidential elections since 1992. Even before then, it was not unheard of for Republican presidential candidates to win handily in downstate Illinois, only to lose statewide due to large Democratic margins in Chicago. The citizens of Chicago have not elected a Republican mayor since 1927, when William Thompson was voted into office. The strength of the party in the city is partly a consequence of Illinois state politics, where the Republicans have come to represent rural and farm concerns while the Democrats support urban issues such as Chicago's public school funding.

Chicago contains less than 25% of the state's population, but it is split between eight of Illinois' 17 districts in the United States House of Representatives. All eight of the city's representatives are Democrats; only two Republicans have represented a significant portion of the city since 1973, for one term each: Robert P. Hanrahan from 1973 to 1975, and Michael Patrick Flanagan from 1995 to 1997.

Machine politics persisted in Chicago after the decline of similar machines in other large U.S. cities.[264] During much of that time, the city administration found opposition mainly from a liberal "independent" faction of the Democratic Party. The independents finally gained control of city government in 1983 with the election of Harold Washington (in office 1983–1987). From 1989 until May 16, 2011, Chicago was under the leadership of its longest-serving mayor, Richard M. Daley, the son of Richard J. Daley. Because of the dominance of the Democratic Party in Chicago, the Democratic primary vote held in the spring is generally more significant than the general elections in November for U.S. House and Illinois State seats. The aldermanic, mayoral, and other city offices are filled through nonpartisan elections with runoffs as needed.[265]

The city is home of former United States President Barack Obama and First Lady Michelle Obama; Barack Obama was formerly a state legislator representing Chicago and later a US senator. The Obamas' residence is located near the University of Chicago in Kenwood on the city's south side.[266]

Chicago Police Department SUV, 2011

Chicago's crime rate in 2020 was 3,926 per 100,000 people.[267] Chicago experienced major rises in violent crime in the 1920s, in the late 1960s, and in the 2020s.[268][269] Chicago's biggest criminal justice challenges have changed little over the last 50 years, and statistically reside with homicide, armed robbery, gang violence, and aggravated battery. Chicago has attracted attention for a high murder rate and perceived crime rate compared to other major cities like New York and Los Angeles. However, while it has a large absolute number of crimes due to its size, Chicago is not among the top-25 most violent cities in the United States.[270][271]

Murder rates in Chicago vary greatly depending on the neighborhood in question.[272] The neighborhoods of Englewood on the South Side, and Austin on the West side, for example, have homicide rates that are ten times higher than other parts of the city.[273] Chicago has an estimated population of over 100,000 active gang members from nearly 60 factions.[274][275] According to reports in 2013, "most of Chicago's violent crime comes from gangs trying to maintain control of drug-selling territories",[276] and is specifically related to the activities of the Sinaloa Cartel, which is active in several American cities.[277] Violent crime rates vary significantly by area of the city, with more economically developed areas having low rates, but other sections have much higher rates of crime.[276] In 2013, the violent crime rate was 910 per 100,000 people;[278] the murder rate was 10.4 – while high crime districts saw 38.9, low crime districts saw 2.5 murders per 100,000.[279]

Chicago has a long history of public corruption that regularly draws the attention of federal law enforcement and federal prosecutors.[280] From 2012 to 2019, 33 Chicago aldermen were convicted on corruption charges, roughly one third of those elected in the time period. A report from the Office of the Legislative Inspector General noted that over half of Chicago's elected alderman took illegal campaign contributions in 2013.[281] Most corruption cases in Chicago are prosecuted by the US Attorney's office, as legal jurisdiction makes most offenses punishable as a federal crime.[282]

When it was opened in 1991, the central Harold Washington Library appeared in Guinness World Records as the largest municipal public library building in the world.

Chicago Public Schools (CPS) is the governing body of the school district that contains over 600 public elementary and high schools citywide, including several selective-admission magnet schools. There are eleven selective enrollment high schools in the Chicago Public Schools,[283] designed to meet the needs of Chicago's most academically advanced students. These schools offer a rigorous curriculum with mainly honors and Advanced Placement (AP) courses.[284] Walter Payton College Prep High School is ranked number one in the city of Chicago and the state of Illinois.[285]

Chicago high school rankings are determined by the average test scores on state achievement tests.[286] The district, with an enrollment exceeding 400,545 students (2013–2014 20th Day Enrollment), is the third-largest in the U.S.[287] On September 10, 2012, teachers for the Chicago Teachers Union went on strike for the first time since 1987 over pay, resources and other issues.[288] According to data compiled in 2014, Chicago's "choice system", where students who test or apply and may attend one of a number of public high schools (there are about 130), sorts students of different achievement levels into different schools (high performing, middle performing, and low performing schools).[289]

Chicago has a network of Lutheran schools,[290] and several private schools are run by other denominations and faiths, such as the Ida Crown Jewish Academy in West Ridge. The Roman Catholic Archdiocese of Chicago operates Catholic schools, that include Jesuit preparatory schools and others. A number of private schools are completely secular. There are also the private Chicago Academy for the Arts, a high school focused on six different categories of the arts and the public Chicago High School for the Arts, a high school focused on five categories (visual arts, theatre, musical theatre, dance, and music) of the arts.[291]

The Chicago Public Library system operates 3 regional libraries and 77 neighbourhood branches, including the central library.[292]

The University of Chicago, as seen from the Midway Plaisance

Since the 1850s, Chicago has been a world center of higher education and research with several universities. These institutions consistently rank among the top "National Universities" in the United States, as determined by U.S. News & World Report.[293] Highly regarded universities in Chicago and the surrounding area are: the University of Chicago; Northwestern University; Illinois Institute of Technology; Loyola University Chicago; DePaul University; Columbia College Chicago and University of Illinois at Chicago. Other notable schools include: Chicago State University; the School of the Art Institute of Chicago; East–West University; National Louis University; North Park University; Northeastern Illinois University; Robert Morris University Illinois; Roosevelt University; Saint Xavier University; Rush University; and Shimer College.[294]

William Rainey Harper, the first president of the University of Chicago, was instrumental in the creation of the junior college concept, establishing nearby Joliet Junior College as the first in the nation in 1901.[295] His legacy continues with the multiple community colleges in the Chicago proper, including the seven City Colleges of Chicago: Richard J. Daley College, Kennedy–King College, Malcolm X College, Olive–Harvey College, Truman College, Harold Washington College and Wilbur Wright College, in addition to the privately held MacCormac College.

Chicago also has a high concentration of post-baccalaureate institutions, graduate schools, seminaries, and theological schools, such as the Adler School of Professional Psychology, The Chicago School of Professional Psychology, the Erikson Institute, The Institute for Clinical Social Work, the Lutheran School of Theology at Chicago, the Catholic Theological Union, the Moody Bible Institute, and the University of Chicago Divinity School.

The Chicago metropolitan area is a major media hub and the third-largest media market in North America, after New York City and Los Angeles.[296] Each of the big four U.S. television networks, CBS, ABC, NBC and Fox, directly owns and operates a high-definition television station in Chicago (WBBM 2, WLS 7, WMAQ 5 and WFLD 32, respectively). Former CW affiliate WGN-TV 9, which was owned from its inception by Tribune Broadcasting (now owned by the Nexstar Media Group since 2019), is carried with some programming differences, as "WGN America" on cable and satellite TV nationwide and in parts of the Caribbean. WGN America eventually became NewsNation in 2021.

Chicago has also been the home of several prominent talk shows, including The Oprah Winfrey Show, Steve Harvey Show, The Rosie Show, The Jerry Springer Show, The Phil Donahue Show, The Jenny Jones Show, and more. The city also has one PBS member station (its second: WYCC 20, removed its affiliation with PBS in 2017[297]): WTTW 11, producer of shows such as Sneak Previews, The Frugal Gourmet, Lamb Chop's Play-Along and The McLaughlin Group.

As of 2018, Windy City Live is Chicago's only daytime talk show, which is hosted by Val Warner and Ryan Chiaverini at ABC7 Studios with a live weekday audience. Since 1999, Judge Mathis also films his syndicated arbitration-based reality court show at the NBC Tower. Beginning in January 2019, Newsy began producing 12 of its 14 hours of live news programming per day from its new facility in Chicago.

Two major daily newspapers are published in Chicago: the Chicago Tribune and the Chicago Sun-Times, with the Tribune having the larger circulation. There are also several regional and special-interest newspapers and magazines, such as Chicago, the Dziennik Związkowy (Polish Daily News), Draugas (the Lithuanian daily newspaper), the Chicago Reader, the SouthtownStar, the Chicago Defender, the Daily Herald, Newcity,[298][299] StreetWise and the Windy City Times. The entertainment and cultural magazine Time Out Chicago and GRAB magazine are also published in the city, as well as local music magazine Chicago Innerview. In addition, Chicago is the home of satirical national news outlet, The Onion, as well as its sister pop-culture publication, The A.V. Club.[300]

Chicago has five 50,000 watt AM radio stations: the CBS Radio-owned WBBM and WSCR; the Tribune Broadcasting-owned WGN; the Cumulus Media-owned WLS; and the ESPN Radio-owned WMVP. Chicago is also home to a number of national radio shows, including Beyond the Beltway with Bruce DuMont on Sunday evenings.

Chicago Public Radio produces nationally aired programs such as PRI's This American Life and NPR's Wait Wait...Don't Tell Me!.

Chicago is a major transportation hub in the United States. It is an important component in global distribution, as it is the third-largest inter-modal port in the world after Hong Kong and Singapore.[301]

The city of Chicago has a higher than average percentage of households without a car. In 2015, 26.5 percent of Chicago households were without a car, and increased slightly to 27.5 percent in 2016. The national average was 8.7 percent in 2016. Chicago averaged 1.12 cars per household in 2016, compared to a national average of 1.8.[302]

Chicago has many parking garages to accommodate for commuters and local residents. Some of the larger garages downtown include Grant Park Garage, East Monroe Street Garage, and Millennium Park Garage. [303][304][305]

Chicago since 2009 has relinquished rights to its public street parking.[306] In 2008, as Chicago struggled to close a growing budget deficit, the city agreed to a 75-year, $1.16 billion deal to lease its parking meter system to an operating company created by Morgan Stanley, called Chicago Parking Meters LLC. Daley said the "agreement is very good news for the taxpayers of Chicago because it will provide more than $1 billion in net proceeds that can be used during this very difficult economy."[307]

The rights of the parking ticket lease end in 2081, and since 2022 have already recouped over $1.5 billion in revenue for Chicago Parking Meters LLC investors.[308]

Seven mainline and four auxiliary interstate highways (55, 57, 65 (only in Indiana), 80 (also in Indiana), 88, 90 (also in Indiana), 94 (also in Indiana), 190, 290, 294, and 355) run through Chicago and its suburbs. Segments that link to the city center are named after influential politicians, with three of them named after former U.S. Presidents (Eisenhower, Kennedy, and Reagan) and one named after two-time Democratic candidate Adlai Stevenson.

The Kennedy and Dan Ryan Expressways are the busiest state maintained routes in the entire state of Illinois.[309]

Chicago Union Station, opened in 1925, is the third-busiest passenger rail terminal in the United States.

The Regional Transportation Authority (RTA) coordinates the operation of the three service boards: CTA, Metra, and Pace.

• The Chicago Transit Authority (CTA) handles public transportation in the City of Chicago and a few adjacent suburbs outside of the Chicago city limits. The CTA operates an extensive network of buses and a rapid transit elevated and subway system known as the Chicago "L" or just "L" (short for "elevated"), with lines designated by colors. These rapid transit lines also serve both Midway and O'Hare Airports. The CTA's rail lines consist of the Red, Blue, Green, Orange, Brown, Purple, Pink, and Yellow lines. Both the Red and Blue lines offer 24‑hour service which makes Chicago one of a handful of cities around the world (and one of two in the United States, the other being New York City) to offer rail service 24 hours a day, every day of the year, within the city's limits.
• Metra, the nation's second-most used passenger regional rail network, operates an 11-line commuter rail service in Chicago and throughout the Chicago suburbs. The Metra Electric Line shares its trackage with Northern Indiana Commuter Transportation District's South Shore Line, which provides commuter service between South Bend and Chicago.
• Pace provides bus and paratransit service in over 200 surrounding suburbs with some extensions into the city as well. A 2005 study found that one quarter of commuters used public transit.[310]

Greyhound Lines provides inter-city bus service to and from the city at the Chicago Bus Station, and Chicago is also the hub for the Midwest network of Megabus (North America).

Amtrak train on the Empire Builder route departs Chicago from Union Station.

Amtrak long distance and commuter rail services originate from Union Station.[311] Chicago is one of the largest hubs of passenger rail service in the nation.[312] The services terminate in the San Francisco area, Washington, D.C., New York City, New Orleans, Portland, Seattle, Milwaukee, Quincy, St. Louis, Carbondale, Boston, Grand Rapids, Port Huron, Pontiac, Los Angeles, and San Antonio. Future services will terminate at Rockford and Moline. An attempt was made in the early 20th century to link Chicago with New York City via the Chicago – New York Electric Air Line Railroad. Parts of this were built, but it was never completed.

In July 2013, the bicycle-sharing system Divvy was launched with 750 bikes and 75 docking stations[313] It is operated by Lyft for the Chicago Department of Transportation.[314] As of July 2019, Divvy operated 5800 bicycles at 608 stations, covering almost all of the city, excluding Pullman, Rosedale, Beverly, Belmont Cragin and Edison Park.[315]

In May 2019, The City of Chicago announced its Chicago's Electric Shared Scooter Pilot Program, scheduled to run from June 15 to October 15.[316] The program started on June 15 with 10 different scooter companies, including scooter sharing market leaders Bird, Jump, Lime and Lyft.[317] Each company was allowed to bring 250 electric scooters, although both Bird and Lime claimed that they experienced a higher demand for their scooters.[318] The program ended on October 15, with nearly 800,000 rides taken.[319]

Chicago is the largest hub in the railroad industry.[320] All five Class I railroads meet in Chicago. As of 2002, severe freight train congestion caused trains to take as long to get through the Chicago region as it took to get there from the West Coast of the country (about 2 days).[321] According to U.S. Department of Transportation, the volume of imported and exported goods transported via rail to, from, or through Chicago is forecast to increase nearly 150 percent between 2010 and 2040.[322] CREATE, the Chicago Region Environmental and Transportation Efficiency Program, comprises about 70 programs, including crossovers, overpasses and underpasses, that intend to significantly improve the speed of freight movements in the Chicago area.[323]

O'Hare International Airport

Chicago is served by O'Hare International Airport, the world's busiest airport measured by airline operations,[324] on the far Northwest Side, and Midway International Airport on the Southwest Side. In 2005, O'Hare was the world's busiest airport by aircraft movements and the second-busiest by total passenger traffic.[325] Both O'Hare and Midway are owned and operated by the City of Chicago. Gary/Chicago International Airport and Chicago Rockford International Airport, located in Gary, Indiana and Rockford, Illinois, respectively, can serve as alternative Chicago area airports, however they do not offer as many commercial flights as O'Hare and Midway. In recent years the state of Illinois has been leaning towards building an entirely new airport in the Illinois suburbs of Chicago.[326] The City of Chicago is the world headquarters for United Airlines, the world's third-largest airline.

The Port of Chicago consists of several major port facilities within the city of Chicago operated by the Illinois International Port District (formerly known as the Chicago Regional Port District). The central element of the Port District, Calumet Harbor, is maintained by the U.S. Army Corps of Engineers.[327]

• Iroquois Landing Lakefront Terminal: at the mouth of the Calumet River, it includes 100 acres (0.40 km²) of warehouses and facilities on Lake Michigan with over 780,000 square meters (8,400,000 square feet) of storage.
• Lake Calumet terminal: located at the union of the Grand Calumet River and Little Calumet River 6 miles (9.7 km) inland from Lake Michigan. Includes three transit sheds totaling over 29,000 square meters (310,000 square feet) adjacent to over 900 linear meters (3,000 linear feet) of ship and barge berthing.
• Grain (14 million bushels) and bulk liquid (800,000 barrels) storage facilities along Lake Calumet.
• The Illinois International Port district also operates Foreign trade zone No. 22, which extends 60 miles (97 km) from Chicago's city limits.

Electricity for most of northern Illinois is provided by Commonwealth Edison, also known as ComEd. Their service territory borders Iroquois County to the south, the Wisconsin border to the north, the Iowa border to the west and the Indiana border to the east. In northern Illinois, ComEd (a division of Exelon) operates the greatest number of nuclear generating plants in any US state. Because of this, ComEd reports indicate that Chicago receives about 75% of its electricity from nuclear power. Recently, the city began installing wind turbines on government buildings to promote renewable energy.[328][329][330]

Natural gas is provided by Peoples Gas, a subsidiary of Integrys Energy Group, which is headquartered in Chicago.

Domestic and industrial waste was once incinerated but it is now landfilled, mainly in the Calumet area. From 1995 to 2008, the city had a blue bag program to divert recyclable refuse from landfills.[331] Because of low participation in the blue bag programs, the city began a pilot program for blue bin recycling like other cities. This proved successful and blue bins were rolled out across the city.[332]

Prentice Women's Hospital on the Northwestern Memorial Hospital Downtown Campus

The Illinois Medical District is on the Near West Side. It includes Rush University Medical Center, ranked as the second best hospital in the Chicago metropolitan area by U.S. News & World Report for 2014–16, the University of Illinois Medical Center at Chicago, Jesse Brown VA Hospital, and John H. Stroger Jr. Hospital of Cook County, one of the busiest trauma centers in the nation.[333]

Two of the country's premier academic medical centers reside in Chicago, including Northwestern Memorial Hospital and the University of Chicago Medical Center. The Chicago campus of Northwestern University includes the Feinberg School of Medicine; Northwestern Memorial Hospital, which is ranked as the best hospital in the Chicago metropolitan area by U.S. News & World Report for 2017–18;[334] the Shirley Ryan AbilityLab (formerly named the Rehabilitation Institute of Chicago), which is ranked the best U.S. rehabilitation hospital by U.S. News & World Report;[335] the new Prentice Women's Hospital; and Ann & Robert H. Lurie Children's Hospital of Chicago.

The University of Illinois College of Medicine at UIC is the second largest medical school in the United States (2,600 students including those at campuses in Peoria, Rockford and Urbana–Champaign).[336]

In addition, the Chicago Medical School and Loyola University Chicago's Stritch School of Medicine are located in the suburbs of North Chicago and Maywood, respectively. The Midwestern University Chicago College of Osteopathic Medicine is in Downers Grove.

The American Medical Association, Accreditation Council for Graduate Medical Education, Accreditation Council for Continuing Medical Education, American Osteopathic Association, American Dental Association, Academy of General Dentistry, Academy of Nutrition and Dietetics, American Association of Nurse Anesthetists, American College of Surgeons, American Society for Clinical Pathology, American College of Healthcare Executives, the American Hospital Association and Blue Cross and Blue Shield Association are all based in Chicago.
