Illinois ( ) is a
state in the
Midwestern region of the
United States. It has the
fifth largest gross domestic product (GDP),
the sixth largest population, and the
25th largest land area of all U.S. states. Illinois has been noted as a
microcosm of the entire United States.
With
Chicago in northeastern Illinois, small industrial cities and immense
agricultural productivity in the north and center of the state, and
natural resources such as coal, timber, and petroleum in the south, Illinois has a diverse economic base, and is a major
transportation hub. The
Port of Chicago connects the state to international ports via two main routes: from the
Great Lakes, via the
Saint Lawrence Seaway, to the
Atlantic Ocean and from the
Great Lakes to the
Mississippi River, via the
Illinois River, through the
Illinois Waterway. The Mississippi River, the
Ohio River, and the
Wabash River form parts of the boundaries of Illinois. For decades, Chicago's
O'Hare International Airport has been ranked as one of the world's busiest airports. Illinois has long had a reputation as a
bellwether both in
social and cultural terms and, through the 1980s, in
politics.
The capital of Illinois is
Springfield, which is located in the central part of the state. Although today Illinois's largest population center is in its northeast, the state's European population grew first in the west as the French settled lands near the Mississippi River, when the region was known as
Illinois Country and was part of
New France. Following the
American Revolutionary War, American settlers began arriving from
Kentucky in the 1780s via the Ohio River, and the population grew from south to north. In 1818, Illinois achieved
statehood. Following increased commercial activity in the Great Lakes after the construction of the
Erie Canal, Chicago was incorporated in the 1830s on the banks of the
Chicago River at one of the few natural harbors on the southern section of
Lake Michigan.
John Deere's invention of the self-scouring
steel plow turned Illinois's rich
prairie into some of the world's most productive and valuable farmland, attracting
immigrant farmers from
Germany and
Sweden. The
Illinois and Michigan Canal (1848) made transportation between the Great Lakes and the Mississippi River valley faster and cheaper, and new railroads carried immigrants to new homes in the country's west and shipped commodity crops to the nation's east. The state became a transportation hub for the nation.
By 1900, the growth of industrial jobs in the northern cities and
coal mining in the central and southern areas attracted immigrants from
Eastern and Southern Europe. Illinois was an important manufacturing center during both world wars. The
Great Migration from the South established a large community of African Americans in the state, including Chicago, who founded the city's famous
jazz and
blues cultures. Chicago, the center of the
Chicago Metropolitan Area, is now recognized as a
global city.
Chicagoland, Chicago's
metropolitan area, encompasses about 65% of the state's population. The most populous
metropolitan areas outside the Chicago area include,
Metro East (of Greater St. Louis),
Peoria and
Rockford.
Three
U.S. presidents have been elected while living in Illinois:
Abraham Lincoln,
Ulysses S. Grant, and
Barack Obama. Additionally,
Ronald Reagan, whose political career was based in
California, was born and raised in the state. Today, Illinois honors Lincoln with its official state slogan ''Land of Lincoln'', which has been displayed on its
license plates since 1954. The state is the site of the
Abraham Lincoln Presidential Library and Museum in Springfield and the future home of the
Barack Obama Presidential Center in Chicago.
Etymology
"Illinois" is the modern spelling for the early
French Catholic missionaries and explorers' name for the
Illinois Native Americans, a name that was spelled in many different ways in the early records.
American scholars previously thought the name "Illinois" meant "man" or "men" in the
Miami-Illinois language, with the original ''iliniwek'' transformed via French into Illinois. This etymology is not supported by the Illinois language, as the word for "man" is ''ireniwa'', and plural of "man" is ''ireniwaki''. The name ''
Illiniwek'' has also been said to mean "tribe of superior men", which is a
false etymology. The name "Illinois" derives from the Miami-Illinois verb ''irenwe·wa''—"he speaks the regular way". This was taken into the
Ojibwe language, perhaps in the
Ottawa dialect, and modified into ''ilinwe·'' (pluralized as ''ilinwe·k''). The French borrowed these forms, spelling the /we/ ending as ''-ois'', a
transliteration of that sound in the French of that time. The current spelling form, ''Illinois'', began to appear in the early 1670s, when French colonists had settled in the western area. The Illinois's name for themselves, as attested in all three of the French missionary-period dictionaries of Illinois, was ''
Inoka'', of unknown meaning and unrelated to the other terms.
History
Geologic history
During the early part of the
Paleozoic Era, the area that would one day become Illinois was submerged beneath a shallow sea and located near the Equator. Diverse marine life lived at this time, including
trilobites,
brachiopods, and
crinoids. Changing environmental conditions led to the formation of large
coal swamps in the
Carboniferous.
Illinois was above sea level for at least part of the
Mesozoic, but by its end was again submerged by the
Western Interior Seaway. This receded by the
Eocene Epoch.
During the
Pleistocene Epoch, vast ice sheets covered much of Illinois, with only the
Driftless Area remaining exposed. These
glaciers carved the basin of
Lake Michigan and left behind traces of ancient glacial lakes and
moraines.
Pre-European
American Indians of successive cultures lived along the waterways of the Illinois area for thousands of years before the arrival of Europeans. The
Koster Site has been excavated and demonstrates 7,000 years of continuous habitation.
Cahokia, the largest regional
chiefdom and
Urban Center of the
Pre-Columbian Mississippian culture, was located near present-day
Collinsville, Illinois. They built an urban complex of more than 100
platform and
burial mounds, a
plaza larger than 35 football fields,
and a woodhenge of sacred cedar, all in a planned design expressing the culture's cosmology.
Monks Mound, the center of the site, is the largest Pre-Columbian structure north of the
Valley of Mexico. It is high, long, wide, and covers .
It contains about of earth.
It was topped by a structure thought to have measured about in length and in width, covered an area , and been as much as high, making its peak above the level of the plaza. The finely crafted ornaments and tools recovered by archaeologists at
Cahokia include elaborate ceramics, finely sculptured stonework, carefully embossed and engraved copper and
mica sheets, and one funeral blanket for an important chief fashioned from 20,000 shell beads. These artifacts indicate that Cahokia was truly an urban center, with clustered housing, markets, and specialists in toolmaking, hide dressing, potting, jewelry making, shell engraving, weaving and salt making.
The civilization vanished in the 15th century for unknown reasons, but historians and archeologists have speculated that the people depleted the area of resources. Many indigenous tribes engaged in constant warfare. According to Suzanne Austin Alchon, "At one site in the central
Illinois River valley, one third of all adults died as a result of violent injuries." The next major power in the region was the
Illinois Confederation or Illini, a political alliance. As the Illini declined during the
Beaver Wars era, members of the
Algonquian-speaking
Potawatomi,
Miami,
Sauk, and other tribes including the Fox (
Mesquakie),
Ioway,
Kickapoo,
Mascouten,
Piankashaw,
Shawnee,
Wea, and Winnebago (
Ho-Chunk) came into the area from the east and north around the Great Lakes.
European exploration and settlement prior to 1800

French explorers
Jacques Marquette and
Louis Jolliet explored the
Illinois River in 1673. Marquette soon after founded a mission at the
Grand Village of the Illinois in
Illinois Country. In 1680, French explorers under
René-Robert Cavelier, Sieur de La Salle and
Henri de Tonti constructed a fort at the site of present-day
Peoria, and in 1682, a fort atop
Starved Rock in today's Starved Rock State Park. French Empire
Canadiens came south to settle particularly along the Mississippi River, and Illinois was part of first
New France, and then of
La Louisiane until 1763, when it passed to the British with their defeat of France in the
Seven Years' War. The small French settlements continued, although many French migrated west to
Ste. Genevieve and
St. Louis, Missouri, to evade British rule.
A few British soldiers were posted in Illinois, but few British or American settlers moved there, as the Crown made it part of the territory reserved for Indians west of the Appalachians, and then part of the
British Province of Quebec. In 1778,
George Rogers Clark claimed
Illinois County for
Virginia. In a compromise, Virginia (and other states that made various claims) ceded the area to the new United States in the 1780s and it became part of the
Northwest Territory, administered by the federal government and later organized as states.
19th century
Prior to statehood
The
Illinois-Wabash Company was an early claimant to much of Illinois. The
Illinois Territory was created on February 3, 1809, with its capital at
Kaskaskia, an early French settlement.
During the discussions leading up to Illinois's
admission to the Union, the proposed northern boundary of the state was moved twice. The original provisions of the
Northwest Ordinance had specified a boundary that would have been tangent to the southern tip of Lake Michigan. Such a boundary would have left Illinois with no shoreline on Lake Michigan at all. However, as Indiana had successfully been granted a northern extension of its boundary to provide it with a usable lakefront, the original bill for Illinois statehood, submitted to Congress on January 23, 1818, stipulated a northern border at the same latitude as Indiana's, which is defined as 10 miles north of the southernmost extremity of Lake Michigan. However, the Illinois delegate,
Nathaniel Pope, wanted more, and lobbied to have the boundary moved further north. The final bill passed by Congress included an amendment to shift the border to 42° 30' north, which is approximately north of the Indiana northern border. This shift added to the state, including the
lead mining region near
Galena. More importantly, it added nearly 50 miles of Lake Michigan shoreline and the Chicago River. Pope and others envisioned a canal that would connect the Chicago and Illinois rivers and thus connect the Great Lakes to the Mississippi.
The State of Illinois prior to the Civil War

In 1818, Illinois became the 21st U.S. state. The capital remained at Kaskaskia, headquartered in a small building rented by the state. In 1819,
Vandalia became the capital, and over the next 18 years, three separate buildings were built to serve successively as the capitol building. In 1837, the state legislators representing
Sangamon County, under the leadership of state representative Abraham Lincoln, succeeded in having the capital moved to
Springfield, where a
fifth capitol building was constructed. A
sixth capitol building was erected in 1867, which continues to serve as the Illinois capitol today.
Though it was ostensibly a "
free state", there was nonetheless
slavery in Illinois. The ethnic French had owned black slaves since the 1720s, and American settlers had already brought slaves into the area from Kentucky. Slavery was nominally banned by the Northwest Ordinance, but that was not enforced for those already holding slaves. When Illinois became a sovereign state in 1818, the Ordinance no longer applied, and about 900 slaves were held in the state. As the southern part of the state, later known as "Egypt" or "Little Egypt", was largely settled by migrants from the South, the section was hostile to free blacks. Settlers were allowed to bring slaves with them for labor, but, in 1822, state residents voted against making slavery legal. Still, most residents opposed allowing free blacks as permanent residents. Some settlers brought in slaves seasonally or as house servants. The Illinois Constitution of 1848 was written with a provision for exclusionary laws to be passed. In 1853,
John A. Logan helped pass a law to prohibit all African Americans, including
freedmen, from settling in the state.
The winter of 1830–1831 is called the "Winter of the Deep Snow"; a sudden, deep snowfall blanketed the state, making travel impossible for the rest of the winter, and many travelers perished. Several severe winters followed, including the "Winter of the Sudden Freeze". On December 20, 1836, a fast-moving cold front passed through, freezing puddles in minutes and killing many travelers who could not reach shelter. The adverse weather resulted in crop failures in the northern part of the state. The southern part of the state shipped food north, and this may have contributed to its name: "
Little Egypt", after the
Biblical story of Joseph in Egypt supplying grain to his brothers.
In 1832, the
Black Hawk War was fought in Illinois and present-day
Wisconsin between the United States and the
Sauk,
Fox (Meskwaki), and
Kickapoo Indian tribes. It represents the end of Indian resistance to white settlement in the Chicago region. The Indians had been forced to leave their homes and move to
Iowa in 1831; when they attempted to return, they were attacked and eventually defeated by U.S. militia. The survivors were forced back to Iowa.
By 1839, the
Latter Day Saints had founded a
utopian city called
Nauvoo. Located in
Hancock County along the Mississippi River, Nauvoo flourished, and soon rivaled Chicago for the position of the state's largest city. But in 1844, the
Latter Day Saint movement founder
Joseph Smith was killed in the
Carthage Jail, about 30 miles away from Nauvoo. Following a
succession crisis (Latter Day Saints),
Brigham Young led most Latter Day Saints out of Illinois in a
mass exodus to present-day
Utah; after close to six years of rapid development, Nauvoo rapidly declined afterward.
After it was established in 1833, Chicago gained prominence as a
Great Lakes port, and then as an
Illinois and Michigan Canal port after 1848, and as a rail hub soon afterward. By 1857, Chicago was Illinois's largest city.
With the tremendous growth of mines and factories in the state in the 19th century, Illinois was the ground for the formation of
labor unions in the United States.
In 1847, after lobbying by
Dorothea L. Dix, Illinois became one of the first states to establish a system of state-supported treatment of mental illness and disabilities, replacing local
almshouses. Dix came into this effort after having met J. O. King, a
Jacksonville, Illinois businessman, who invited her to Illinois, where he had been working to build an asylum for the insane. With the lobbying expertise of Dix, plans for the Jacksonville State Hospital (now known as the
Jacksonville Developmental Center) were signed into law on March 1, 1847.
Civil War and after
During the
American Civil War, Illinois ranked fourth in men who served (more than 250,000) in the
Union Army, a figure surpassed by only New York,
Pennsylvania, and
Ohio. Beginning with President
Abraham Lincoln's first call for troops and continuing throughout the war, Illinois mustered 150 infantry regiments, which were numbered from the 7th to the 156th regiments. Seventeen cavalry regiments were also gathered, as well as two light artillery regiments. The town of
Cairo, at the southern tip of the state at the confluence of the Mississippi and Ohio Rivers, served as a strategically important supply base and training center for the
Union army. For several months, both General
Grant and Admiral
Foote had headquarters in Cairo.
During the Civil War, and more so afterwards, Chicago's population skyrocketed, which increased its prominence. The
Pullman Strike and
Haymarket Riot, in particular, greatly influenced the development of the American
labor movement. From Sunday, October 8, 1871, until Tuesday, October 10, 1871, the
Great Chicago Fire burned in downtown Chicago, destroying .
20th century
At the turn of the 20th century, Illinois had a population of nearly 5 million. Many people from other parts of the country were attracted to the state by employment caused by the expanding industrial base. Whites were 98% of the state's population.
Bolstered by continued
immigration from southern and eastern Europe, and by the African-American
Great Migration from the South, Illinois grew and emerged as one of the most important states in the union. By the end of the century, the population had reached 12.4 million.
The
Century of Progress World's fair was held at Chicago in 1933. Oil strikes in
Marion County and
Crawford County led to a boom in 1937, and by 1939, Illinois ranked fourth in U.S. oil production. Illinois manufactured 6.1 percent of total United States military armaments produced during
World War II, ranking seventh among the 48 states. Chicago became an ocean port with the opening of the
Saint Lawrence Seaway in 1959. The seaway and the
Illinois Waterway connected Chicago to both the Mississippi River and the
Atlantic Ocean. In 1960,
Ray Kroc opened the first
McDonald's franchise in
Des Plaines (which still exists as a museum, with a working McDonald's across the street).
Illinois had a prominent role in the emergence of the
nuclear age. In 1942, as part of the
Manhattan Project, the
University of Chicago conducted the first sustained
nuclear chain reaction. In 1957,
Argonne National Laboratory, near
Chicago, activated the first experimental nuclear power generating system in the United States. By 1960, the first privately financed nuclear plant in the United States,
Dresden 1, was dedicated near
Morris. In 1967,
Fermilab, a national nuclear research facility near
Batavia, opened a
particle accelerator, which was the world's largest for over 40 years. With eleven plants currently operating, Illinois leads all states in the amount of electricity generated from nuclear power.
In 1961, Illinois became the first state in the nation to adopt the recommendation of the
American Law Institute and pass a comprehensive criminal code revision that repealed the law against
sodomy. The code also abrogated
common law crimes and established an
age of consent of 18. The state's
fourth constitution was adopted in 1970, replacing the 1870 document.
The first
Farm Aid concert was held in
Champaign to benefit American farmers, in 1985. The worst
upper Mississippi River flood of the century, the
Great Flood of 1993, inundated many towns and thousands of acres of farmland.
21st century
On August 28, 2017, Illinois Governor
Bruce Rauner signed a bill into law that prohibited state and local police from arresting anyone solely due to their immigration status or due to federal detainers. Some fellow Republicans criticized Rauner for his action, claiming the bill made Illinois a
sanctuary state.
Geography
Illinois is located in the
Midwest region of the United States and is one of the eight states and Ontario, Canada, in the
Great Lakes region of North America.
Boundaries
Illinois's eastern border with
Indiana consists of a north–south line at 87° 31′ 30″ west longitude in
Lake Michigan at the north, to the
Wabash River in the south above
Post Vincennes. The Wabash River continues as the eastern/southeastern border with Indiana until the Wabash enters the
Ohio River. This marks the beginning of Illinois's southern border with
Kentucky, which runs along the northern shoreline of the Ohio River. Most of the western border with
Missouri and
Iowa is the
Mississippi River; Kaskaskia is an
exclave of Illinois, lying west of the Mississippi and reachable only from Missouri. The state's northern border with
Wisconsin is fixed at 42° 30′ north latitude. The northeastern border of Illinois lies in
Lake Michigan, within which Illinois shares a water boundary with the state of
Michigan, as well as Wisconsin and Indiana.
Topography
Though Illinois lies entirely in the
Interior Plains, it does have some minor variation in its elevation. In extreme northwestern Illinois, the
Driftless Area, a region of unglaciated and therefore higher and more rugged topography, occupies a small part of the state.
Southern Illinois includes the hilly areas around the
Shawnee National Forest.
Charles Mound, located in the Driftless region, has the state's highest natural elevation above sea level at . Other highlands include the
Shawnee Hills in the south, and there is varying topography along its rivers; the
Illinois River bisects the state northeast to southwest. The floodplain on the Mississippi River from
Alton to the
Kaskaskia River is known as the
American Bottom.
Divisions

Illinois has three major geographical divisions.
Northern Illinois is dominated by
Chicago metropolitan area, or Chicagoland, which is the city of Chicago and its suburbs, and the adjoining exurban area into which the metropolis is expanding. As defined by the federal government, the Chicago metro area includes several counties in Illinois,
Indiana, and
Wisconsin, and has a population of over 9.8 million. Chicago itself is a cosmopolitan city, densely populated, industrialized, the transportation hub of the nation, and settled by a wide variety of ethnic groups. The city of
Rockford, Illinois's third-largest city and center of the state's fourth largest metropolitan area, sits along Interstates
39 and
90 some northwest of Chicago. The
Quad Cities region, located along the
Mississippi River in northern Illinois, had a population of 381,342 in 2011.
The midsection of Illinois is the second major division, called
Central Illinois. It is an area of mainly
prairie and known as the Heart of Illinois. It is characterized by small towns and medium–small cities. The western section (west of the Illinois River) was originally part of the
Military Tract of 1812 and forms the conspicuous western bulge of the state. Agriculture, particularly
corn and
soybeans, as well as educational institutions and manufacturing centers, figure prominently in Central Illinois. Cities include
Peoria;
Springfield, the state capital;
Quincy;
Decatur;
Bloomington-Normal; and
Champaign-
Urbana.
The third division is
Southern Illinois, comprising the area south of
U.S. Route 50, including
Little Egypt, near the juncture of the
Mississippi River and
Ohio River. Southern Illinois is the site of the ancient city of
Cahokia, as well as the site of the first state capital at
Kaskaskia, which today is separated from the rest of the state by the Mississippi River.
This region has a somewhat warmer winter climate, different variety of crops (including some cotton farming in the past), more rugged topography (due to the area remaining unglaciated during the
Illinoian Stage, unlike most of the rest of the state), as well as small-scale oil deposits and coal mining. The Illinois suburbs of
St. Louis, such as
East St. Louis, are located in this region, and collectively, they are known as the
Metro-East. The other somewhat significant concentration of population in Southern Illinois is the Carbondale-Marion-Herrin, Illinois Combined Statistical Area centered on
Carbondale and
Marion, a two-county area that is home to 123,272 residents.
A portion of southeastern Illinois is part of the extended
Evansville, Indiana, Metro Area, locally referred to as the Tri-State with Indiana and Kentucky. Seven Illinois counties are in the area.
In addition to these three, largely latitudinally defined divisions, all of the region outside the Chicago Metropolitan area is often called "
downstate" Illinois. This term is flexible, but is generally meant to mean everything outside the influence of the Chicago area. Thus, some cities in ''Northern'' Illinois, such as
DeKalb, which is west of Chicago, and
Rockford—which is actually north of Chicago—are sometimes incorrectly considered to be 'downstate'.
Climate
Illinois has a climate that varies widely throughout the year. Because of its nearly 400-mile distance between its northernmost and southernmost extremes, as well as its mid-continental situation, most of Illinois has a
humid continental climate (
Köppen climate classification ''Dfa''), with hot, humid summers and cold winters. The southern part of the state, from about
Carbondale southward, has a
humid subtropical climate (Koppen ''Cfa''), with more moderate winters. Average yearly precipitation for Illinois varies from just over at the southern tip to around in the northern portion of the state. Normal annual snowfall exceeds in the Chicago area, while the southern portion of the state normally receives less than .

Illinois averages approximately 51 days of
thunderstorm activity a year, which ranks somewhat above average in the number of thunderstorm days for the United States. Illinois is vulnerable to tornadoes, with an average of 35 occurring annually, which puts much of the state at around five tornadoes per annually.

Demographics

The
United States Census Bureau estimates that the population of Illinois was 12,671,821 in 2019, moving from the fifth-largest state to the sixth-largest state (losing out to Pennsylvania). Illinois's population declined by 79,500 people from 2019 to 2020, which is not the largest decline of any state in the U.S. in raw terms, as New York state anticipates a loss of 126,355 people.
This includes a natural increase since the last census of 462,146 people (i.e., 1,438,187 births minus 976,041 deaths) and an decrease due to net migration of 622,928 people. Immigration resulted in a net increase of 242,945 people, and migration from within the U.S. resulted in a net decrease of 865,873 people.
Illinois is the most populous state in the
Midwest region. Chicago, the
third-most populous city in the United States, is the center of the
Chicago metropolitan area or
Chicagoland, as this area is nicknamed. Although Chicagoland comprises only 9% of the land area of the state, it contains 65% of the state's residents. The losses of population anticipated from the 2020 Census results do not arise from the Chicago metro area; rather the declines are from the Downstate counties.
According to the
2010 Census, the
racial composition of the state was:
* 71.5% White American (63.7% non-Hispanic white, 7.8% White Hispanic)
* 14.5% Black or
African American
* 0.3%
American Indian and
Alaska Native
* 4.6%
Asian American
* 2.3% Multiracial American
* 6.8% some other race
In the same year 15.8% of the total population was of
Hispanic or Latino origin (they may be of any race).
According to 2018 U.S. Census Bureau estimates, Illinois's population was 71.7%
White (60.9% Non-Hispanic White), 5.6%
Asian, 5.6% Some Other Race, 14.1% Black or
African American, 0.3%
Native Americans and
Alaskan Native, 0.1%
Pacific Islander and 2.7% from
two or more races.
The White population continues to remain the largest racial category in Illinois as Hispanics primarily identify as White (62.2%) with others identifying as Some Other Race (31.2%), Multiracial (3.9%), Black (1.5%), American Indian and Alaskan Native (0.8%), Asian (0.3%), and Hawaiian and Pacific Islander (0.1%).
By ethnicity, 17.3% of the total population is
Hispanic-Latino (of any race) and 82.7% is Non-Hispanic (of any race). If treated as a separate category, Hispanics are the largest minority group in Illinois.
The state's most populous ethnic group, non-Hispanic white, has declined from 83.5% in 1970 to 60.90% in 2018.
, 49.4% of Illinois's population younger than age 1 were minorities (Note: Children born to white Hispanics or to a sole full or partial minority parent are counted as minorities).
At the 2007 estimates from the
U.S. Census Bureau, there were 1,768,518 foreign-born inhabitants of the state or 13.8% of the population, with 48.4% from Latin America, 24.6% from Asia, 22.8% from Europe, 2.9% from Africa, 1.2% from Canada, and 0.2% from Oceania. Of the foreign-born population, 43.7% were
naturalized U.S. citizens, and 56.3% were not U.S. citizens.
In 2007, 6.9% of Illinois's population was reported as being under age 5, 24.9% under age 18 and 12.1% were age 65 and over. Females made up approximately 50.7% of the population.
According to the 2007 estimates, 21.1% of the population had
German ancestry, 13.3% had
Irish ancestry, 8% had
British ancestry, 7.9% had
Polish ancestry, 6.4% had
Italian ancestry, 4.6% listed themselves as
American, 2.4% had
Swedish ancestry, 2.2% had
French ancestry, other than
Basque, 1.6% had
Dutch ancestry, and 1.4% had
Norwegian ancestry.
Illinois also has large numbers of
African Americans and Latinos (mostly
Mexicans and
Puerto Ricans).
Chicago, along the shores of Lake Michigan, is the nation's third largest city. In 2000, 23.3% of Illinois's population lived in the city of Chicago, 43.3% in Cook County, and 65.6% in the counties of the
Chicago metropolitan area: Will, DuPage, Kane, Lake, and McHenry counties, as well as Cook County. The remaining population lives in the smaller cities and rural areas that dot the state's plains. As of 2000, the state's
center of population was at , located in
Grundy County, northeast of the village of
Mazon.
Birth data
''Births do not add up, because Hispanics are counted both by ethnicity and by race.''
* Since 2016, data for births of
White Hispanic origin are not collected, but included in one ''Hispanic'' group; persons of Hispanic origin may be of any race.
Urban areas
Chicago is the largest city in the state and the
third-most populous city in the United States, with its 2010 population of 2,695,598. The
U.S. Census Bureau currently lists seven other cities with populations of over 100,000 within Illinois. Based upon the Census Bureau's official 2010 population:
Aurora, a Chicago
satellite town that eclipsed
Rockford for the title of second-most populous city in Illinois; its 2010 population was 197,899. Rockford, at 152,871, is the third-largest city in the state, and is the largest city in the state not located within the Chicago suburbs.
Joliet, located in metropolitan Chicago, is the fourth-largest city in the state, with a population of 147,433.
Naperville, a suburb of Chicago, is fifth with 141,853. Naperville and Aurora share a boundary along
Illinois Route 59.
Springfield, the state's capital, comes in as sixth-most populous with 117,352 residents.
Peoria, which decades ago was the second-most populous city in the state, is seventh with 115,007. The eighth-largest and final city in the 100,000 club is
Elgin, a northwest suburb of Chicago, with a 2010 population of 108,188.
The most populated city in the state south of
Springfield is
Belleville, with 44,478 people at the
2010 census. It is located in the Illinois portion of
Greater St. Louis (often called the
Metro-East area), which has a rapidly growing population of over 700,000.
Other major urban areas include the
Champaign-Urbana Metropolitan Area, which has a combined population of almost 230,000 people, the Illinois portion of the
Quad Cities area with about 215,000 people, and the
Bloomington-Normal area with a combined population of over 165,000.
Languages
The
official language of Illinois is
English, although between 1923 and 1969, state law gave official status to "the American language". Nearly 80% of people in Illinois speak English natively, and most of the rest speak it fluently as a second language. A number of dialects of
American English are spoken, ranging from
Inland Northern American English and
African-American English around Chicago, to
Midland American English in Central Illinois, to
Southern American English in the far south.
Over 20% of Illinoians speak a language other than English at home, of which
Spanish is by far the most widespread, at more than 12% of the total population.
A sizeable number of
Polish speakers is present in the
Chicago Metropolitan Area.
Illinois Country French has mostly gone extinct in Illinois, although it is still celebrated in the
French Colonial Historic District.
Religion
Christianity
Roman Catholics constitute the single largest religious denomination in Illinois; they are heavily concentrated in and around Chicago, and account for nearly 30% of the state's population. However, taken together ''as a group'', the various Protestant denominations comprise a greater percentage of the state's population than do Catholics. In 2010 Catholics in Illinois numbered 3,648,907. The largest Protestant denominations were the
United Methodist Church with 314,461, and the
Southern Baptist Convention, with 283,519 members. Illinois has one of the largest concentrations of
Missouri Synod Lutherans in the United States.
Illinois played an important role in the early
Latter Day Saint movement, with
Nauvoo, Illinois, becoming a gathering place for Mormons in the early 1840s. Nauvoo was the location of the
succession crisis, which led to the separation of the Mormon movement into
several Latter Day Saint sects.
The Church of Jesus Christ of Latter-day Saints, the largest of the sects to emerge from the Mormon schism, has more than 55,000 adherents in Illinois today.
Other Abrahamic religious communities
A significant number of adherents of other
Abrahamic faiths can be found in Illinois. Largely concentrated in the
Chicago metropolitan area, followers of the
Muslim,
Baháʼí, and
Jewish religions all call the state home.
Muslims constituted the largest non-Christian group, with 359,264 adherents.
Illinois has the largest concentration of Muslims by state in the country, with 2,800 Muslims per 100,000 citizens. The largest and oldest surviving
Baháʼí House of Worship in the world is located in
Wilmette, Illinois, The Chicago area has a very large Jewish community, particularly in the suburbs of
Skokie,
Buffalo Grove,
Highland Park, and surrounding suburbs. Former Chicago Mayor
Rahm Emanuel is the Windy City's first Jewish mayor.
Other religions
Chicago is also home to a very large population of
Hindus,
Sikhs,
Jains, and
Buddhists.
The
Baháʼí House of Worship in Wilmette is the center of that religion's worship in North America.
Economy
The dollar
gross state product for Illinois was estimated to be billion in 2019. The state's 2019
per capita gross state product was estimated to be around $72,000.
As of February 2019, the unemployment rate in Illinois reached 4.2%.
Illinois's
minimum wage will rise to $15 per hour by 2025, making it one of the highest in the nation.
Agriculture
Illinois's major agricultural outputs are
corn,
soybeans,
hogs,
cattle,
dairy products, and wheat. In most years, Illinois is either the first or second state for the highest production of soybeans, with a harvest of 427.7 million bushels (11.64 million
metric tons) in 2008, after Iowa's production of 444.82 million bushels (12.11 million metric tons). Illinois ranks second in U.S. corn production with more than 1.5 billion bushels produced annually.
With a production capacity of 1.5 billion gallons per year, Illinois is a top producer of ethanol, ranking third in the United States in 2011.
Illinois is a leader in food manufacturing and meat processing.
[Facts About Illinois Agriculture](_blank)
, Illinois Department of Agriculture. Accessed online April 16, 2012 Although Chicago may no longer be "
Hog Butcher for the World", the Chicago area remains a global center for
food manufacture and meat processing,
with many plants, processing houses, and distribution facilities concentrated in the area of the former
Union Stock Yards. Illinois also produces
wine, and the state is home to two
American viticultural areas. In the area of The Meeting of the Great Rivers Scenic Byway, peaches and apples are grown. The German immigrants from agricultural backgrounds who settled in Illinois in the mid- to late 19th century are in part responsible for the profusion of fruit orchards in that area of Illinois. Illinois's universities are actively researching alternative agricultural products as alternative crops.
Manufacturing
Illinois is one of the nation's manufacturing leaders, boasting annual value added productivity by manufacturing of over $107 billion in 2006. , Illinois is ranked as the 4th-most productive manufacturing state in the country, behind California, Texas, and Ohio. About three-quarters of the state's manufacturers are located in the Northeastern Opportunity Return Region, with 38 percent of Illinois's approximately 18,900 manufacturing plants located in Cook County. As of 2006, the leading manufacturing industries in Illinois, based upon value-added, were chemical manufacturing ($18.3 billion), machinery manufacturing ($13.4 billion), food manufacturing ($12.9 billion), fabricated metal products ($11.5 billion), transportation equipment ($7.4 billion), plastics and rubber products ($7.0 billion), and computer and electronic products ($6.1 billion).
Services
By the early 2000s, Illinois's economy had moved toward a dependence on high-value-added services, such as financial trading, higher education, law, logistics, and medicine. In some cases, these services clustered around institutions that hearkened back to Illinois's earlier economies. For example, the
Chicago Mercantile Exchange, a trading exchange for global
derivatives, had begun its life as an agricultural
futures market. Other important non-manufacturing industries include publishing, tourism, and energy production and distribution.
Investments
Venture capitalists funded a total of approximately $62 billion in the U.S. economy in 2016. Of this amount, Illinois-based companies received approximately $1.1 billion. Similarly, in FY 2016, the federal government spent $461 billion on contracts in the U.S. Of this amount, Illinois-based companies received approximately $8.7 billion.
Energy
Illinois is a net importer of fuels for energy, despite large coal resources and some minor oil production. Illinois exports electricity, ranking fifth among states in electricity production and seventh in electricity consumption.
[Illinois in the Global Energy Marketplace]
, Robert Finley, 2001. Illinois State Geological Survey publication.
Coal
The coal industry of Illinois has its origins in the middle 19th century, when entrepreneurs such as
Jacob Loose discovered coal in locations such as
Sangamon County.
Jacob Bunn contributed to the development of the Illinois coal industry, and was a founder and owner of the
Western Coal & Mining Company of Illinois. About 68% of Illinois has coal-bearing strata of the
Pennsylvanian geologic period. According to the Illinois State Geological Survey, 211 billion tons of
bituminous coal are estimated to lie under the surface, having a total heating value greater than the estimated oil deposits in the
Arabian Peninsula. However, this coal has a high
sulfur content, which causes
acid rain, unless special equipment is used to reduce
sulfur dioxide emissions.
Many Illinois
power plants are not equipped to burn high-sulfur coal. In 1999, Illinois produced 40.4 million tons of coal, but only 17 million tons (42%) of Illinois coal was consumed in Illinois. Most of the coal produced in Illinois is exported to other states and countries. In 2008, Illinois exported three million tons of coal, and was projected to export nine million in 2011, as demand for energy grows in places such as China, India, and elsewhere in Asia and Europe. , Illinois was ranked third in recoverable coal reserves at producing mines in the nation.
Most of the coal produced in Illinois is exported to other states, while much of the coal burned for power in Illinois (21 million tons in 1998) is mined in the
Powder River Basin of
Wyoming.
Mattoon was chosen as the site for the
Department of Energy's
FutureGen project, a 275-megawatt experimental
zero emission coal-burning power plant that the DOE just gave a second round of funding. In 2010, after a number of setbacks, the city of Mattoon backed out of the project.
Petroleum
Illinois is a leading refiner of petroleum in the American
Midwest, with a combined crude oil distillation capacity of nearly . However, Illinois has very limited crude oil proved reserves that account for less than 1% of the U.S. total reserves. Residential heating is 81% natural gas compared to less than 1%
heating oil. Illinois is ranked 14th in
oil production among states, with a daily output of approximately in 2005.

Nuclear power
Nuclear power arguably began in Illinois with the
Chicago Pile-1, the world's first artificial self-sustaining
nuclear chain reaction in the world's first
nuclear reactor, built on the
University of Chicago campus. There are six operating
nuclear power plants in Illinois:
Braidwood,
Byron,
Clinton,
Dresden,
LaSalle, and
Quad Cities. With the exception of the single-unit Clinton plant, each of these facilities has two reactors. Three reactors have been permanently shut down and are in various stages of decommissioning:
Dresden-1 and
Zion-1 and 2. Illinois ranked first in the nation in 2010 in both nuclear capacity and nuclear generation. Generation from its nuclear power plants accounted for 12 percent of the nation's total.
In 2007, 48% of Illinois's electricity was generated using nuclear power.
The
Morris Operation is the only de facto high-level radioactive waste storage site in the United States.
Wind power
Illinois has seen growing interest in the use of
wind power for electrical generation. Most of Illinois was rated in 2009 as "marginal or fair" for wind energy production by the
U.S. Department of Energy, with some western sections rated "good" and parts of the south rated "poor". These ratings are for wind turbines with hub heights; newer wind turbines are taller, enabling them to reach
stronger winds farther from the ground. As a result, more areas of Illinois have become prospective wind farm sites. As of September 2009, Illinois had 1116.06
MW of installed wind power
nameplate capacity with another 741.9 MW under construction.
Illinois ranked ninth among U.S. states in installed wind power capacity, and sixteenth by potential capacity.
Large
wind farms in Illinois include
Twin Groves,
Rail Splitter,
EcoGrove, and
Mendota Hills.
As of 2007, wind energy represented only 1.7% of Illinois's energy production, and it was estimated that wind power could provide 5–10% of the state's energy needs. Also, the
Illinois General Assembly mandated in 2007 that by 2025, 25% of all electricity generated in Illinois is to come from
renewable resources.
Biofuels
Illinois is ranked second in
corn production among U.S. states, and Illinois corn is used to produce 40% of the
ethanol consumed in the United States.
The
Archer Daniels Midland corporation in
Decatur, Illinois, is the world's leading producer of ethanol from corn.
The National Corn-to-Ethanol Research Center (NCERC), the world's only facility dedicated to researching the ways and means of converting corn (maize) to ethanol is located on the campus of
Southern Illinois University Edwardsville.
University of Illinois at Urbana–Champaign is one of the partners in the
Energy Biosciences Institute (EBI), a $500 million biofuels research project funded by petroleum giant
BP.
Taxes
Tax is collected by the
Illinois Department of Revenue. State
income tax is calculated by multiplying
net income by a
flat rate. In 1990, that rate was set at 3%, but in 2010, the General Assembly voted for a temporary increase in the rate to 5%; the new rate went into effect on January 1, 2011; the personal income rate partially sunset on January 1, 2015, to 3.75%, while the corporate income tax fell to 5.25%. Illinois failed to pass a budget from 2015 to 2017, after the 736-day
budget impasse, a budget was passed in Illinois after lawmakers overturned Governor Bruce Rauner's veto; this budget raised the personal income rate to 4.95% and the corporate rate to 7%. There are two rates for state
sales tax: 6.25% for general merchandise and 1% for qualifying food, drugs, and medical appliances. The
property tax is a major source of tax revenue for local government taxing districts. The property tax is a local—not state—tax, imposed by local government taxing districts, which include counties,
townships, municipalities,
school districts, and special taxation districts. The property tax in Illinois is imposed only on
real property.
On May 1, 2019, the Illinois Senate voted to approve a
constitutional amendment that would have stricken language from the
Illinois Constitution requiring a flat state income tax, in a 73–44 vote. If approved, the amendment would have allowed the state legislature to impose a graduated income tax based on annual income. The governor,
J.B. Pritzker, approved the bill on May 27, 2019. It was scheduled for a 2020 general election ballot vote
and required 60 percent voter approval to effectively amend the state constitution.
The amendment was not approved by Illinoisans, with 55.1% of voters voting "No" on approval and 44.9% voting "Yes."
As of 2017 Chicago had the highest state and local sales tax rate for a U.S. city with a populations above 200,000, at 10.250%. The state of Illinois has the second highest rate of real estate tax: 2.31%, which is second only to New Jersey at 2.44%.
Toll roads are a ''de facto'' user tax on the citizens and visitors to the state of Illinois. Illinois ranks seventh out of the 11 states with the most miles of toll roads, at 282.1 miles. Chicago ranks fourth in most expensive toll roads in America by the mile, with the
Chicago Skyway charging 51.2 cents per mile. Illinois also has the 11th highest gasoline tax by state, at 37.5 cents per gallon.
Culture
Museums
Illinois has numerous museums; the greatest concentration of these are in Chicago. Several museums in Chicago are ranked as some of the best in the world. These include the
John G. Shedd Aquarium, the
Field Museum of Natural History, the
Art Institute of Chicago, the
Adler Planetarium, and the
Museum of Science and Industry.
The modern
Abraham Lincoln Presidential Library and Museum in Springfield is the largest and most attended
presidential library in the country. The Illinois State Museum boasts a collection of 13.5 million objects that tell the story of Illinois life, land, people, and art. The ISM is among only 5% of the nation's museums that are accredited by the American Alliance of Museums. Other historical museums in the state include the
Polish Museum of America in
Chicago;
Magnolia Manor in
Cairo;
Easley Pioneer Museum in
Ipava; the
Elihu Benjamin Washburne;
Ulysses S. Grant Homes, both in
Galena; and the Chanute Air Museum, located on the former Chanute Air Force Base in Rantoul.
The Chicago metropolitan area also hosts two zoos: The
Brookfield Zoo, located about ten miles west of the city center in suburban
Brookfield, contains more than 2,300 animals and covers . The
Lincoln Park Zoo is located in
Lincoln Park on Chicago's North Side, approximately north of the
Loop. The zoo accounts for more than of the park.

Music
Illinois is a leader in music education, having hosted the
Midwest Clinic International Band and Orchestra Conference since 1946, as well being home to the Illinois Music Educators Association (IMEA), one of the largest professional music educator's organizations in the country. Each summer since 2004,
Southern Illinois University Carbondale has played host to the Southern Illinois Music Festival, which presents dozens of performances throughout the region. Past featured artists include the
Eroica Trio and violinist
David Kim.
Chicago, in the northeast corner of the state, is a
major center for music in the
midwestern United States where distinctive forms of blues (greatly responsible for the future creation of
rock and roll), and
house music, a genre of electronic dance music, were developed.
The
Great Migration of poor black workers from the South into the industrial cities brought traditional
jazz and
blues music to the city, resulting in
Chicago blues and "Chicago-style"
Dixieland jazz. Notable blues artists included
Muddy Waters,
Junior Wells,
Howlin' Wolf and both
Sonny Boy Williamsons; jazz greats included
Nat King Cole,
Gene Ammons,
Benny Goodman, and
Bud Freeman. Chicago is also well known for its
soul music.
In the early 1930s,
Gospel music began to gain popularity in Chicago due to
Thomas A. Dorsey's contributions at
Pilgrim Baptist Church.
In the 1980s and 1990s,
heavy rock,
punk, and
hip hop also became popular in Chicago.
Orchestras in Chicago include the
Chicago Symphony Orchestra, the
Lyric Opera of Chicago, and the
Chicago Sinfonietta.
Movies
John Hughes, who moved from
Grosse Pointe to
Northbrook, based many films of his in
Chicago, and its suburbs.
Ferris Bueller's Day Off,
Home Alone,
The Breakfast Club, and all his films take place in the fictional Shermer, Illinois (the original name of Northbrook was Shermerville, and Hughes's High School,
Glenbrook North High School, is on Shermer Road). Most locations in his films include Glenbrook North, the former
Maine North High School, the
Ben Rose House in Highland Park, and the famous Home Alone house in
Winnetka, Illinois.

Law and politics
thumb|Illinois House of Representatives
State government
The
government of Illinois, under the
Constitution of Illinois, has three branches of government: executive, legislative and judicial. The executive branch is split into several statewide elected offices, with the governor as chief executive. Legislative functions are granted to the Illinois General Assembly. The judiciary is composed of the Supreme Court and lower courts.
The
Illinois General Assembly is the state legislature, composed of the 118-member
Illinois House of Representatives and the 59-member
Illinois Senate. The members of the General Assembly are elected at the beginning of each even-numbered year. The ''
Illinois Compiled Statutes'' (ILCS) are the
codified statutes of a general and permanent nature.
The executive branch is composed of six elected officers and their offices as well as numerous other departments.
[ The six elected officers are:][ Governor, Lieutenant Governor, Attorney General, Secretary of State, Comptroller, and Treasurer. The government of Illinois has numerous departments, agencies, boards and commissions, but the so-called code departments provide most of the state's services.]
The Judiciary of Illinois is the unified court system of Illinois. It consists of the Supreme Court, Appellate Court, and Circuit Courts. The Supreme Court oversees the administration of the court system.
The administrative divisions of Illinois are counties, townships, precincts, cities, towns, villages, and special-purpose districts. The basic subdivision of Illinois are the 102 counties. Eighty-five of the 102 counties are in turn divided into townships and precincts. Municipal governments are the cities, villages, and incorporated towns. Some localities possess ''home rule'', which allows them to govern themselves to a certain extent.
Party balance
Illinois is a Democratic stronghold. Historically, Illinois was a political swing state, with near-parity existing between the Republican and the Democratic parties. However, in recent elections, the Democratic Party has gained ground, and Illinois has come to be seen as a solid "blue" state in presidential campaigns. Votes from Chicago and most of Cook County have long been strongly Democratic. However, the "collar counties" (the suburbs surrounding Chicago's Cook County, Illinois), can be seen as moderate voting districts. College towns like Carbondale, Champaign, and Normal also lean Democratic.
Republicans continue to prevail in the rural areas of northern and central Illinois, as well as southern Illinois outside of East St. Louis. From 1920 until 1972, Illinois was carried by the victor of each of these 14 presidential elections. In fact, the state was long seen as a national bellwether, supporting the winner in every election in the 20th century, except for 1916 and 1976. By contrast, Illinois has trended more toward the Democratic party, and has voted for their presidential candidates in the last six elections; in 2000, George W. Bush became the first Republican to win the presidency without carrying either Illinois or Vermont. Local politician and Chicago resident Barack Obama easily won the state's 21 electoral votes in 2008, with 61.9% of the vote. In 2010, incumbent governor Pat Quinn was re-elected with 47% of the vote, while Republican Mark Kirk was elected to the Senate with 48% of the vote. In 2012, President Obama easily carried Illinois again, with 58% to Republican candidate Mitt Romney's 41%. In 2014, Republican Bruce Rauner defeated Governor Quinn 50% to 46% to become Illinois's first Republican governor in 12 years after being sworn in on January 12, 2015, while Democratic senator Dick Durbin was re-elected with 53% of the vote. In 2016, Hillary Clinton carried Illinois with 55% of the vote, and Tammy Duckworth defeated incumbent Mark Kirk 54% to 40%. George W. Bush and Donald Trump are the only Republican presidential candidates to win without carrying either Illinois or Vermont. In 2018, Democrat JB Pritzker defeated the incumbent Bruce Rauner for the governorship with 54% of the vote.
History of corruption
Politics in the state have been infamous for highly visible corruption cases, as well as for crusading reformers, such as governors Adlai Stevenson and James R. Thompson. In 2006, former governor George Ryan was convicted of racketeering and bribery, leading to a six-and-a-half-year prison sentence. In 2008, then-Governor Rod Blagojevich was served with a criminal complaint on corruption charges, stemming from allegations that he conspired to sell the vacated Senate seat left by President Barack Obama to the highest bidder. Subsequently, on December 7, 2011, Rod Blagojevich was sentenced to 14 years in prison for those charges, as well as perjury while testifying during the case, totaling 18 convictions. Blagojevich was impeached and convicted by the legislature, resulting in his removal from office. In the late 20th century, Congressman Dan Rostenkowski was imprisoned for mail fraud; former governor and federal judge Otto Kerner, Jr. was imprisoned for bribery; Secretary of State Paul Powell was investigated and found to have gained great wealth through bribes, and State Auditor of Public Accounts (Comptroller) Orville Hodge was imprisoned for embezzlement. In 1912, William Lorimer, the GOP boss of Chicago, was expelled from the U.S. Senate for bribery and in 1921, Governor Len Small was found to have defrauded the state of a million dollars.
U.S. presidential elections
Illinois has shown a strong presence in presidential elections. Three presidents have claimed Illinois as their political base when running for president: Abraham Lincoln, Ulysses S. Grant, and most recently Barack Obama. Lincoln was born in Kentucky, but he moved to Illinois at age 21. He served in the General Assembly and represented the 7th congressional district in the U.S. House of Representatives before his election to the presidency in 1860. Ulysses S. Grant was born in Ohio and had a military career that precluded settling down, but on the eve of the Civil War and approaching middle age, he moved to Illinois and thus utilized the state as his home and political base when running for president. Barack Obama was born in Hawaii and made Illinois his home after graduating from law school, and later represented Illinois in the U.S. Senate. He then became president in 2008, running as a candidate from his Illinois base.
Ronald Reagan was born in Illinois, in the city of Tampico, raised in Dixon, Illinois, and educated at Eureka College, outside Peoria. Reagan later moved to California during his young adulthood. He then became an actor, and later became California's Governor before being elected president.
Hillary Clinton was born and raised in the suburbs of Chicago and became the first woman to represent a major political party in the general election of the U.S. presidency. Clinton ran from a platform based in New York State.
African-American U.S. senators
Nine African-Americans have served as members of the United States Senate. Of which three have represented Illinois, the most of any single state: Carol Moseley-Braun, Barack Obama, and Roland Burris, who was appointed to replace Obama after his election to the presidency. Moseley-Braun was the first African-American woman to become a U.S. Senator.
Political families
Three families from Illinois have played particularly prominent roles in the Democratic Party, gaining both statewide and national fame.
Stevenson
The Stevenson family, initially rooted in central Illinois and later based in the Chicago metropolitan area, has provided four generations of Illinois officeholders.
* Adlai Stevenson I (1835–1914) was a Vice President of the United States, as well as a Congressman
* Lewis Stevenson (1868–1929), son of Adlai, served as Illinois Secretary of State.
* Adlai Stevenson II (1900–1965), son of Lewis, served as Governor of Illinois and as the U.S. Ambassador to the United Nations; he was also the Democratic party's presidential nominee in 1952 and 1956, losing both elections to Dwight Eisenhower.
* Adlai Stevenson III (1930–), son of Adlai II, served ten years as a United States Senator.
Daley
The Daley family's powerbase was in Chicago.
* Richard J. Daley (1902–1976) served as Mayor of Chicago from 1955 to his death.
* Richard M. Daley (1942–), son of Richard J, was Chicago's longest-serving mayor, in office from 1989 to 2011.
* William M. Daley (1948–), another son of Richard J, is a former White House Chief of Staff and has served in a variety of appointed positions.
Pritzker
The Pritzker family is based in Chicago and have played important roles in both the private and the public sectors.
* Jay Pritzker (1922–1999), co-founder of Hyatt Hotel based in Chicago.
* Penny Pritzker (born 1959), 38th United States Secretary of Commerce under President Barack Obama.
* J.B. Pritzker (born 1965), current and 43rd governor of Illinois and co-founder of the Pritzker Group.
Education
Illinois State Board of education
The Illinois State Board of Education (ISBE) is autonomous of the governor and the state legislature, and administers public education in the state. Local municipalities and their respective school districts operate individual public schools, but the ISBE audits performance of public schools with the Illinois School Report Card. The ISBE also makes recommendations to state leaders concerning education spending and policies.
Primary and secondary schools
Education is compulsory for ages 7–17 in Illinois. Schools are commonly, but not exclusively, divided into three tiers of primary and secondary education: elementary school, middle school or junior high school, and high school. District territories are often complex in structure. Many areas in the state are actually located in ''two'' school districts—one for high school, the other for elementary and middle schools. And such districts do not necessarily share boundaries. A given high school may have several elementary districts that feed into it, yet some of those feeder districts may themselves feed into multiple high school districts.
Colleges and universities
Using the criterion established by the Carnegie Foundation for the Advancement of Teaching, there are eleven "National Universities" in the state.
The University of Chicago is continuously ranked as one of the world's top ten universities on various independent university rankings, and its Booth School of Business, along with Northwestern's Kellogg School of Management consistently rank within the top five graduate business schools in the country and top ten globally. The University of Illinois at Urbana–Champaign is often ranked among the best engineering schools in the world and in United States.
, six of these rank in the "first tier" among the top 500 National Universities in the nation, as determined by the ''U.S. News & World Report'' rankings: the University of Chicago, Northwestern University, the University of Illinois at Urbana–Champaign, Loyola University Chicago, the Illinois Institute of Technology, DePaul University, University of Illinois at Chicago, Illinois State University, Southern Illinois University Carbondale, and Northern Illinois University.
Illinois also has more than twenty additional accredited four-year universities, both public and private, and dozens of small liberal arts colleges across the state. Additionally, Illinois supports 49 public community colleges in the Illinois Community College System.
School financing
Schools in Illinois are funded primarily by property taxes, based on state assessment of property values, rather than direct state contributions. Scholar Tracy Steffes has described Illinois public education as historically “inequitable,” a system where one of “the wealthiest of states” is “the stingiest in its support for education.” There have been several attempts to reform school funding in Illinois. The most notable attempt came in 1973 with the adoption of the Illinois Resource Equalizer Formula, a measure through which it was hoped funding could be collected and distributed to Illinois schools more equitably. However, opposition from affluent Illinois communities who objected to having to pay for the less well-off school districts (many of them Black majority communities, produced by redlining, white flight, and other “soft” segregation methods) resulted in the formula’s abolition in the late 1980s.
Infrastructure
Transportation
Because of its central location and its proximity to the Rust Belt and Grain Belt, Illinois is a national crossroads for air, auto, rail, and truck traffic.
Airports
From 1962 until 1998, Chicago's O'Hare International Airport (ORD) was the busiest airport in the world, measured both in terms of total flights and passengers. While it was surpassed by Atlanta's Hartsfield in 1998 (as Chicago splits its air traffic between O'Hare and Midway airports, while Atlanta uses only one airport), with 59.3 million domestic passengers annually, along with 11.4 million international passengers in 2008, O'Hare consistently remains one of the two or three busiest airports globally, and in some years still ranks number one in total flights. It is a major hub for both United Airlines and American Airlines, and a major airport expansion project is currently underway. Midway Airport (MDW), which had been the busiest airport in the world at one point until it was supplanted by O'Hare as the busiest airport in 1962, is now the secondary airport in the Chicago metropolitan area and still ranks as one of the nation's busiest airports. Midway is a major hub for Southwest Airlines and services many other carriers as well. Midway served 17.3 million domestic and international passengers in 2008.
Rail
Illinois has an extensive passenger and freight rail transportation network. Chicago is a national Amtrak hub and in-state passengers are served by Amtrak's Illinois Service, featuring the Chicago to Carbondale ''Illini'' and ''Saluki'', the Chicago to Quincy ''Carl Sandburg'' and ''Illinois Zephyr'', and the Chicago to St. Louis ''Lincoln Service''. Currently there is trackwork on the Chicago–St. Louis line to bring the maximum speed up to , which would reduce the trip time by an hour and a half. Nearly every North American railway meets at Chicago, making it the largest and most active rail hub in the country. Extensive commuter rail is provided in the city proper and some immediate suburbs by the Chicago Transit Authority's 'L' system. One of the largest suburban commuter rail system in the United States, operated by Metra, uses existing rail lines to provide direct commuter rail access for hundreds of suburbs to the city and beyond.
In addition to the state's rail lines, the Mississippi River and Illinois River provide major transportation routes for the state's agricultural interests. Lake Michigan gives Illinois access to the Atlantic Ocean by way of the Saint Lawrence Seaway.
Interstate highway system
The Interstate Highways in Illinois are all segments of the Interstate Highway System that are owned and maintained by the state.
Illinois has the distinction of having the most primary (two-digit) interstates pass through it among all the 50 states with 13. Illinois also ranks third among the fifty states with the most interstate mileage, coming in after California and Texas, which are much bigger states in area.
Major U.S. Interstate highways crossing the state include: Interstate 24 (I-24), I-39, I-41, I-55, I-57, I-64, I-70, I-72, I-74, I-80, I-88, I-90, and I-94.
U.S. highway system
The Illinois Department of Transportation (IDOT) is responsible for maintaining the U.S Highways in Illinois. The system in Illinois consists of 21 primary highways.
Among the U.S. highways that pass through the state, the primary ones are: US 6, US 12, US 14, US 20, US 24, US 30, US 34, US 36, US 40, US 41, US 45, US 50, US 51, US 52, US 54, US 60, US 62, and US 67.
