Chicago
Most populous city in Illinois, United States

Chicago, the most populous city in Illinois and the Midwestern United States, is the third-most populous city in the U.S. with over 2.7 million residents as of the 2020 census. Located on Lake Michigan, it is the seat of Cook County and the center of the Chicago metropolitan area. Known for its contributions to urban planning and architecture, Chicago is an international hub for finance, culture, commerce, and transportation, featuring O'Hare International Airport. The city attracts millions of visitors annually, drawn to its cultural institutions, vibrant music scene, and professional sports teams, hosting events like the Chicago Marathon.

Etymology and nicknames

Main article: Nicknames of Chicago

See also: Windy City (nickname) and List of Chicago placename etymologies

The name Chicago is derived from a French rendering of the indigenous Miami–Illinois name Šikaakonki, the locative form of the word šikaakwa which can mean both "skunk" and "ramps," a wild relative of onion and garlic known to botanists as Allium tricoccum.17 The first known reference to the site of the city of Chicago as "Checagou" was by Robert de LaSalle around 1679 in a memoir.18 Henri Joutel, in his journal of 1688, noted that the eponymous wild "garlic" grew profusely in the area.19 According to his diary of late September 1687:

... when we arrived at the said place called "Chicagou" which, according to what we were able to learn of it, has taken this name because of the quantity of garlic which grows in the forests in this region.20

The city has had several nicknames throughout its history, such as the Windy City, Chi-Town, Second City, and City of the Big Shoulders.21

History

Main article: History of Chicago

For a chronological guide, see Timeline of Chicago history.

Beginnings

In the mid-18th century, the area was inhabited by the Potawatomi, an indigenous tribe who had succeeded the Miami, Sauk and Meskwaki peoples in this region.22

The first known permanent settler in Chicago was a trader, Jean Baptiste Point du Sable. Du Sable was of African descent, perhaps born in the French colony of Saint-Domingue (Haiti), and he established the settlement in the 1780s. He is commonly known as the "Founder of Chicago."232425

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 U.S. 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.26

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.272829

19th century

On August 12, 1833, the Town of Chicago was organized with a population of about 200.30 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, 1837,31 and for several decades was the world's fastest-growing city.32

As the site of the Chicago Portage,33 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.34353637

A flourishing economy brought residents from rural communities and immigrants from abroad. Manufacturing and retail and finance sectors became dominant, influencing the American economy.38 The Chicago Board of Trade (established 1848) listed the first-ever standardized "exchange-traded" forward contracts, which were called futures contracts.39

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.40 These issues also helped propel another Illinoisan, Abraham Lincoln, to the national stage. Lincoln was nominated in Chicago for U.S. 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.41 The project raised much of central Chicago to a new grade with the use of jackscrews for raising buildings.42 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.434445

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.464748 Much of the city, including railroads and stockyards, survived intact,49 and from the ruins of the previous wooden structures arose more modern constructions of steel and stone. These set a precedent for worldwide construction.5051 During its rebuilding period, Chicago constructed the world's first skyscraper in 1885, using steel-skeleton construction.5253

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.54 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).5556

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 1889.57 Programs that were developed there became a model for the new field of social work.58

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.59

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.60

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.6162 In 1883, Chicago's railway managers needed a general time convention, so they developed the standardized system of North American time zones.63 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.6465 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.6667

20th and 21st centuries

1900 to 1939

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 233,903.68 This Great Migration had an immense cultural impact, called the Chicago Black Renaissance, part of the New Negro Movement, in art, literature, and music.69 Continuing racial tensions and violence, such as the Chicago race riot of 1919, also occurred.70

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.71 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.72

From 1920 to 1921, the city was affected by a series of tenant rent strikes, which lead to the formation of the Chicago Tenants Protective association, passage of the Kessenger tenant laws, and of a heat ordinance that legally required flats to be kept above 68 °F during winter months by landlords.737475767778

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.79

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.80

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.81 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 began 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.82 The theme of the fair was technological innovation over the century since Chicago's founding.83

1940 to 1979

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 – 1945.84

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.85

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 1945.86

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.87

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.88 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.89 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.90

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.91 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.92 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.93

1980 to present

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.94 Washington was succeeded by 6th ward alderperson 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.9596

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.97 The area was shut down for three days and some buildings did not reopen for weeks; losses were estimated at $1.95 billion.98

On February 23, 2011, Rahm Emanuel, a former White House Chief of Staff and member of the House of Representatives, won the mayoral election.99 Emanuel was sworn in as mayor on May 16, 2011, and won re-election in 2015.100 Lori Lightfoot, the city's first African American woman mayor and its first openly LGBTQ mayor, was elected to succeed Emanuel as mayor in 2019.101 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.102

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

Geography

Topography

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.103104

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.105

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.106 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,107 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.108

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.109 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.110111112

Communities

See also: Community areas in Chicago and List of neighborhoods in Chicago

Major sections of the city include the central business district, called the Loop, and the North, South, and West Sides.113 The three sides of the city are represented on the Flag of Chicago by three horizontal white stripes.114 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.115 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.116

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.117118

Streetscape

Main article: Roads and expressways in Chicago

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.119 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.120

In 2021, Chicago was ranked the fourth-most walkable large city in the United States.121 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.122 Other notable streets include Michigan Avenue, State Street, 95th Street, Cicero Avenue, Clark Street, and Belmont Avenue. The City Beautiful movement inspired Chicago's boulevards and parkways.123

Architecture

Further information: List of tallest buildings in Chicago and List of Chicago Landmarks

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,124 which would then be followed by many other cities around the world.125 Today, Chicago's skyline is among the world's tallest and densest.126

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.127 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.128129

The Merchandise Mart, once the largest building in the world, had its own zip code until 2008, and stands near the junction of the North and South branches of the Chicago River.130 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.131

Chicago gave its name to the Chicago School and was home to the Prairie School, two movements in architecture.132 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.133134

A popular tourist activity is to take an architecture boat tour along the Chicago River.135

Monuments and public art

Main article: List of public art in Chicago

Chicago is famous for its outdoor public art with donors establishing funding for such art as far back as Benjamin Ferguson's 1905 trust.136 A number of Chicago's public art works are by modern figurative artists. Among these are Chagall's Four Seasons; the Chicago Picasso; Miró'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.137138

Climate

Main articles: Climate of Chicago and Tornadoes in Chicago

The city mostly lies within the typical hot-summer humid continental climate (Köppen: Dfa), and experiences four distinct seasons.139140141 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 2011.142 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, 1985.143144145 Measurable snowfall can continue through the first or second week of April.146

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.147 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.148

According to the National Weather Service, Chicago's highest official temperature reading of 105 °F (41 °C) was recorded on July 24, 1934.149 Midway Airport reached 109 °F (43 °C) one day prior and recorded a heat index of 125 °F (52 °C) during the 1995 heatwave.150 The lowest official temperature of −27 °F (−33 °C) was recorded on January 20, 1985, at O'Hare Airport.151152 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.153 Notably, the F4 Oak Lawn tornado moved through the South Side of the city on April 21, 1967, moving onto Lake Michigan as a waterspout.154 Downtown Chicago was struck by an F3 tornado on May 6, 1876, again moving out over Lake Michigan.155

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,156 which is sufficient to give lakefront areas such as Northerly Island a humid subtropical (Cfa) climate using Köppen's 27 °F (−3 °C) winter isotherm (as opposed to the firmly continental climate of inland areas such as Midway and O'Hare International Airports),157 even though those areas are still continental (Dca) under Trewartha due to winters averaging below 32 °F (0 °C).158 Northeast winds from wintertime cyclones departing south of the region sometimes bring the city lake-effect snow.159

During its first hundred years, Chicago was one of the fastest-growing cities in the world. When founded in 1833, fewer than 200 people had settled on what was then the American frontier. By the time of its first census, seven years later, the population had reached over 4,000. In the forty years from 1850 to 1890, the city's population grew from slightly under 30,000 to over 1 million. At the end of the 19th century, Chicago was the 5th-most populous city in the world,176 and the largest of the cities that did not exist at the dawn of the century. Within sixty years of the Great Chicago Fire of 1871, the population went from about 300,000 to over 3 million,177 and reached its highest ever recorded population of 3.6 million for the 1950 census.

From the last two decades of the 19th century, Chicago was the destination of waves of immigrants from Ireland, Southern, Central and Eastern Europe, including Italians, Jews, Russians, Poles, Greeks, Lithuanians, Bulgarians, Albanians, Romanians, Turks, Croatians, Serbs, Bosnians, Montenegrins and Czechs.178179 To these ethnic groups, the basis of the city's industrial working class, were added an additional influx of African Americans from the American South—with Chicago's black population doubling between 1910 and 1920 and doubling again between 1920 and 1930.180 Chicago has a significant Bosnian population, many of whom arrived in the 1990s and 2000s.181

In the 1920s and 1930s, the great majority of African Americans moving to Chicago settled in a so‑called "Black Belt" on the city's South Side.182 A large number of blacks also settled on the West Side. By 1930, two-thirds of Chicago's black population lived in sections of the city which were 90% black in racial composition.183 Around that time, a lesser known fact about African Americans on the North Side is that the block of 4600 Winthrop Avenue in Uptown was the only block African Americans could live or open establishments.184185 Chicago's South Side emerged as United States second-largest urban black concentration, following New York's Harlem. In 1990, Chicago's South Side and the adjoining south suburbs constituted the largest black majority region in the entire United States.186 Since the 1980s, Chicago has had a massive exodus of African Americans (primarily from the South and West sides) to its suburbs or outside its metropolitan area.187 The above average crime and cost of living were leading reasons for the fast declining African American population in Chicago.188189190

Most of Chicago's foreign-born population were born in Mexico, Poland or India.191 A 2020 study estimated the total Jewish population of the Chicago metropolitan area, both religious and irreligious, at 319,500.192

Chicago's population declined in the latter half of the 20th century, from over 3.6 million in 1950 down to under 2.7 million by 2010. By the time of the official census count in 1990, it was overtaken by Los Angeles as the United States' second largest city.193

The city has seen a rise in population for the 2000 census and after a decrease in 2010, it rose again for the 2020 census.194

According to U.S. census estimates as of July 2019, Chicago's largest racial or ethnic group is non-Hispanic White at 32.8% of the population, Blacks at 30.1% and the Hispanic population at 29.0% of the population.195196197198

The city's waterfront location and nightlife attracts residents and tourists alike. Over a third of the city population is concentrated in the lakefront neighborhoods from Rogers Park in the north to South Shore in the south.253 The city has many upscale dining establishments as well as many ethnic restaurant districts. These districts include the Mexican American neighborhoods, such as Pilsen along 18th street, and La Villita along 26th Street; the Puerto Rican enclave of Paseo Boricua in the Humboldt Park neighborhood; Greektown, along South Halsted Street, immediately west of downtown;254 Little Italy, along Taylor Street; Chinatown in Armour Square; Polish Patches in West Town; Little Seoul in Albany Park around Lawrence Avenue; Little Vietnam near Broadway in Uptown; and the Desi area, along Devon Avenue in West Ridge.255

Downtown is the center of Chicago's financial, cultural, governmental, and commercial institutions and the site of Grant Park and many of the city's skyscrapers. Many of the city's financial institutions, such as the CBOT and the Federal Reserve Bank of Chicago, are located within a section of downtown called "The Loop", which is an eight-block by five-block area of city streets that is encircled by elevated rail tracks. The term "The Loop" is largely used by locals to refer to the entire downtown area as well. The central area includes the Near North Side, the Near South Side, and the Near West Side, as well as the Loop. These areas contribute famous skyscrapers, abundant restaurants, shopping, museums, Soldier Field, convention facilities, parkland, and beaches.

It also contains the University of Chicago, ranked one of the world's top ten universities,259 and the Museum of Science and Industry. The 6-mile (9.7 km) long Burnham Park stretches along the waterfront of the South Side. Two of the city's largest parks are also located on this side of the city: Jackson Park, bordering the waterfront, hosted the World's Columbian Exposition in 1893, and is the site of the aforementioned museum; and slightly west sits Washington Park. The two parks themselves are connected by a wide strip of parkland called the Midway Plaisance, running adjacent to the University of Chicago. The South Side hosts one of the city's largest parades, the annual African American Bud Billiken Parade and Picnic, which travels through Bronzeville to Washington Park. Ford Motor Company has an automobile assembly plant on the South Side in Hegewisch, and most of the facilities of the Port of Chicago are also on the South Side.

The city's distinctive accent, made famous by its use in classic films like The Blues Brothers and television programs like the Saturday Night Live skit "Bill Swerski's Superfans", is an advanced form of Inland Northern American English. This dialect can also be found in other cities bordering the Great Lakes such as Cleveland, Milwaukee, Detroit, and Rochester, New York, and most prominently features a rearrangement of certain vowel sounds, such as the short 'a' sound as in "cat", which can sound more like "kyet" to outsiders. The accent remains well associated with the city.261

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.265 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".266

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.267

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.275 The Chicago-style thin crust is also popular in the city.276 Certain Chicago pizza favorites include Lou Malnati's and Giordano's.277

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.278 Enthusiasts of the Chicago-style hot dog frown upon the use of ketchup as a garnish, but may prefer to add giardiniera.279280281

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.

Literature

Further information: Chicago literature

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.289 Nonetheless, Chicagoans worked hard to create a literary tradition that would stand the test of time,290 and create a "city of feeling" out of concrete, steel, vast lake, and open prairie.291 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.292 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.293 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.294 In the 1980s, a modern form of poetry performance began in Chicago, the poetry slam.295

Sports

Main article: Sports in Chicago

The city has two Major League Baseball (MLB) teams: the Chicago Cubs of the National League play in Wrigley Field on the North Side; and the Chicago White Sox of the American League play in Rate Field on the South Side. The two teams have faced each other in a World Series only once, in 1906.296

The Cubs are the oldest Major League Baseball team to have never changed their city;297 they have played in Chicago since 1871.298 They had the dubious honor of having the longest championship drought in American professional sports, failing to win a World Series between 1908 and 2016. The White Sox have played on the South Side continuously since 1901. They have won three World Series titles (1906, 1917, 2005) and six American League pennants, including the first in 1901.

Chicago has also entered into esports with the creation of the OpTic Chicago, a professional Call of Duty team that participates within the CDL.307

Parks and greenspace

Main articles: Parks in Chicago, Chicago Boulevard System, and Cook County Forest Preserves

When Chicago was incorporated in 1837, it chose the motto Urbs in Horto, a Latin phrase which means "City in a Garden". Today, the Chicago Park District consists of more than 570 parks with over 8,000 acres (3,200 ha) of municipal parkland. There are 31 sand beaches, a plethora of museums, two world-class conservatories, and 50 nature areas.308 Lincoln Park, the largest of the city's parks, covers 1,200 acres (490 ha) and has over 20 million visitors each year, making it third in the number of visitors after Central Park in New York City, and the National Mall and Memorial Parks in Washington, D.C.309

There is a historic boulevard system,310 a network of wide, tree-lined boulevards which connect a number of Chicago parks.311 The boulevards and the parks were authorized by the Illinois legislature in 1869.312 A number of Chicago neighborhoods emerged along these roadways in the 19th century.313 The building of the boulevard system continued intermittently until 1942. It includes nineteen boulevards, eight parks, and six squares, along twenty-six miles of interconnected streets.314 The Chicago Park Boulevard System Historic District was listed on the National Register of Historic Places in 2018.315316

With berths for more than 6,000 boats, the Chicago Park District operates the nation's largest municipal harbor system.317 In addition to ongoing beautification and renewal projects for the existing parks, a number of new parks have been added in recent years, such as the Ping Tom Memorial Park in Chinatown, DuSable Park on the Near North Side, and most notably, Millennium Park, which is in the northwestern corner of one of Chicago's oldest parks, Grant Park in the Chicago Loop.

The wealth of greenspace afforded by Chicago's parks is further augmented by the Cook County Forest Preserves, a network of open spaces containing forest, prairie, wetland, streams, and lakes that are set aside as natural areas which lie along the city's outskirts,318 including both the Chicago Botanic Garden in Glencoe and the Brookfield Zoo in Brookfield.319 Washington Park is also one of the city's biggest parks; covering nearly 400 acres (160 ha). The park is listed on the National Register of Historic Places listings in South Side Chicago.320

Law and government

Government

Main article: Government of Chicago

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 incumbent 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 alderpersons, one elected from each ward in the city.321 The council takes official action through the passage of ordinances and resolutions and approves the city budget.322

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.

Politics

201682.9% 912,94512.3% 135,3204.8% 53,262

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.324 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.325 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.326

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 U.S. senator. The Obamas' residence is located near the University of Chicago in Kenwood on the city's south side.327

Crime

Main articles: Crime in Chicago and Timeline of organized crime in Chicago

Chicago's crime rate in 2020 was 3,926 per 100,000 people.328 Chicago experienced major rises in violent crime in the 1920s, in the late 1960s, and in the 2020s.329330 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 a higher murder rate than the larger cities of 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.331332

Murder rates in Chicago vary greatly depending on the neighborhood in question.333 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.334 Chicago has an estimated population of over 100,000 active gang members from nearly 60 factions.335336 According to reports in 2013, "most of Chicago's violent crime comes from gangs trying to maintain control of drug-selling territories,"337 and is specifically related to the activities of the Sinaloa Cartel, which is active in several American cities.338 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.339 In 2013, the violent crime rate was 910 per 100,000 people;340 the murder rate was 10.4 per 100,000 – while high crime districts saw 38.9 murders, low crime districts saw 2.5 murders per 100,000.341

Chicago's long history of public corruption regularly draws the attention of federal law enforcement and federal prosecutors.342 From 2012 to 2019, 33 Chicago alderpersons 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 alderpersons took illegal campaign contributions in 2013.343 Most corruption cases in Chicago are prosecuted by the U.S. Attorney's office, as legal jurisdiction makes most offenses punishable as a federal crime.344

Education

Schools and libraries

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, 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.345 Walter Payton College Prep High School is ranked number one in the city of Chicago and the state of Illinois.346

Chicago high school rankings are determined by the average test scores on state achievement tests.347 The district, with an enrollment exceeding 400,545 students (2013–2014 20th Day Enrollment), is the third-largest in the U.S.348 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.349 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).350

Chicago has a network of Lutheran schools,351 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, including Jesuit preparatory schools and others. A number of private schools are completely secular. There is also the private Chicago Academy for the Arts, a high school focused on six different artistic disciplines, and the public Chicago High School for the Arts, a high school focused on five disciplines (visual arts, theatre, musical theatre, dance, and music).352

The Chicago Public Library system operates three regional libraries and 77 neighborhood branches, including the central library.353

Colleges and universities

For a more comprehensive list, see List of colleges and universities in Chicago.

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.354 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 the University of Illinois 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.355

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 1901.356 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 the Erikson Institute, Institute for Clinical Social Work, Lutheran School of Theology at Chicago, Catholic Theological Union, Moody Bible Institute, and University of Chicago Divinity School.

Television

The Chicago metropolitan area is a major media hub and the third-largest media market in the United States, after New York City and Los Angeles.357 Each of the big five U.S. television networks, NBC, ABC, CBS, Fox and The CW, directly owns and operates a high-definition television station in Chicago (WMAQ 5, WLS 7, WBBM 2, WFLD 32 and WGN-TV 9, respectively). WGN is owned by the CW through a majority stake held in the network by the Nexstar Media Group, which acquired it from its founding owner Tribune Broadcasting in 2019. WGN was once 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 2017358): 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.

Television stations

Most of Chicago's television stations are owned and operated by the big television network companies. They are:

Newspapers

Two major daily newspapers are published in Chicago: the Chicago Tribune and the Chicago Sun-Times, with the Tribune having the larger circulation.

Infrastructure

Transportation

Further information: Transportation in Chicago

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.362

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 1.8.363

Parking

Due to Chicago's wheel tax,364 residents of Chicago who own a vehicle are required to purchase a Chicago City Vehicle Sticker.365 In established Residential Parking Zones, only local residents can purchase Zone-specific parking stickers for themselves and guests.366367

Chicago since 2009 has relinquished rights to its public street parking.368 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."369

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.370

Expressways

Further information: Roads and expressways in Chicago

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.371

Transit systems

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 the "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.372

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).

Passenger rail

Amtrak long distance and commuter rail services originate from Union Station.373 Chicago is one of the largest hubs of passenger rail service in the nation.374 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 service will terminate at 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.

Bicycle and scooter sharing systems

In July 2013, the bicycle-sharing system Divvy was launched with 750 bikes and 75 docking stations375 It is operated by Lyft for the Chicago Department of Transportation.376 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.377

In May 2019, The City of Chicago announced its Chicago's Electric Shared Scooter Pilot Program, scheduled to run from June 15 to October 15.378 The program started on June 15 with 10 different scooter companies, including scooter sharing market leaders Bird, Jump, Lime and Lyft.379 Each company was allowed to bring 250 electric scooters, although both Bird and Lime claimed that they experienced a higher demand for their scooters.380 The program ended on October 15, with nearly 800,000 rides taken.381

Freight rail

Chicago is the largest hub in the railroad industry.382 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).383 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 2040.384 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.385

Airports

Further information: Transportation in Chicago § Airports

Chicago is served by O'Hare International Airport, the world's busiest airport measured by airline operations,386 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.387 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.388 The City of Chicago is the world headquarters for United Airlines, the world's third-largest airline.

Port authority

Main article: Port of Chicago

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.389

  • 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 sq ft) 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 sq ft) 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.

Utilities

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 U.S. 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.390391392

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.393 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.394

Health systems

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.395

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;396 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;397 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).398

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.
