Illinois

"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 transformed via French into Illinois. This etymology is not supported by the Illinois language, as the word for "man" is , and plural of "man" is . The name has also been said to mean 'tribe of superior men', ==History==

Pre-European found at the Saddle Site in Union County, Illinois 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. Around the time of European contact in 1673, the Illinois confederation had an estimated population of over 10,000 people. As the Illini declined during the Beaver Wars era, members of the Algonquian-speaking Potawatomi, Miami, Sauk, and other tribes including the Meskwaki, Iowa, Kickapoo, Mascouten, Piankeshaw, Shawnee, Wea, and 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. 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. State of Illinois prior to the Civil War was admitted as the state of Illinois, and the rest was joined to Michigan Territory. , Edward Coles brought his slaves from his home state of Virginia to give them their freedom when they arrived in Illinois. : Abraham Lincoln and other area legislators were instrumental in moving the state capitol to centrally located Springfield in 1839. 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 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. Edward Coles, the second Governor of Illinois who was born in Virginia, participated in a campaign to block extending existing slavery in Illinois after winning the 1822 Illinois gubernatorial election. In 1824, state residents voted against making slavery legal by a vote of 6640 against to 4972 for. 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 a coalition of the Sauk, Meskwaki, and Kickapoo peoples, who had been forced to leave their homes and relocate to Iowa in 1831. The tribes had lost their territory east of the Mississippi river in Illinois under a disputed treaty in 1804. The natives, under Sauk chief Black Hawk, attempted to return to Illinois in April 1832 to reclaim this land. They were attacked and defeated by the U.S. Militia and rival tribes allied with the US forces, including the Potawatomi, Dakota, Menominee, and Ho-Chunk. The survivors of Black Hawk's band were forced back to Iowa. This represented the end of native resistance to white settlement in the Chicago and Northern Illinois regions. By 1832, when the last native lands in Illinois were ceded to the United States, the indigenous population of the state had been reduced by infectious diseases, warfare, and forced westward removal to only one village with fewer than 300 inhabitants. But in that same year, the Latter Day Saint movement founder, Joseph Smith, was killed in the Carthage Jail, about 30 miles away from Nauvoo. Following a succession crisis, 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 quickly 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. Civil War and after troops embarking at Cairo on January 10, 1862 During the American Civil War, Illinois ranked fourth in soldiers 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, killing 300 people and destroying . 20th century in Chicago. in 1993. 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 was demolished in 1984. In 1985 a replica was built on the same site to recreate how the original one looked. 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. The 2002 election brought Democrat Rod Blagojevich to the governor's mansion. It also brought future president Barack Obama into a committee leadership position in the Illinois Senate, where he drafted the Health Care Justice Act, a forerunner of the Affordable Care Act. Obama's election to the presidency in Blagojevich's second term set off a chain of events culminating in Blagojevich's impeachment, trial, and subsequent criminal conviction and imprisonment, making Blagojevich the second consecutive Illinois governor to be convicted on federal corruption charges. Blagojevich's replacement Pat Quinn was defeated by Republican Bruce Rauner in the 2014 election. Disagreements between the governor and legislature over budgetary policy led to the Illinois Budget Impasse, a 793-day period stretching from 2015 to 2018 in which the state had no budget and struggled to pay its bills. On August 28, 2017, 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. In the 2018 election, Rauner was replaced by J. B. Pritzker, returning the state government to a Democratic trifecta. In January 2020 the state legalized marijuana. On March 9, 2020, Pritzker issued a disaster proclamation due to the COVID-19 pandemic. He ended the state of emergency in May 2023. ==Geography==

Illinois is located in the Midwest region of the United States and is one of the eight states in the Great Lakes region of North America. 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 , the highest natural point in Illinois at above sea level, is located in the Driftless Area in the northwestern part of the state. 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. Geology 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. Divisions and the confluence of the Ohio and Mississippi Rivers. 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. Historically prairie, it is now mainly agricultural 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. 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. The all-time high temperature was , recorded on July 14, 1954, at East St. Louis, and the all-time low temperature was , recorded on January 31, 2019, during the January 2019 North American cold wave at a weather station near Mount Carroll, and confirmed on March 5, 2019. This followed the previous record of recorded on January 5, 1999, near Congerville. 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 54 occurring annually, which puts much of the state at about five tornadoes per annually. Some of Tornado Alley's deadliest tornadoes on record have occurred in the state. The Tri-State Tornado of 1925 killed 695 people in three states; 613 of the victims died in Illinois. Urban areas Chicago is the largest city in the state and the third-most populous city in the United States, with a population of 2,746,388 in 2020. Furthermore, over 7 million residents of the Chicago metropolitan area reside in Illinois. The U.S. Census Bureau currently lists seven other cities with populations of over 100,000 within the state. This includes the Chicago satellite towns of Aurora, Joliet, Naperville, and Elgin, as well as the cities of Rockford, the most populous city in the state outside of the Chicago area; Springfield, the state's capital; and Peoria. The most populated city in the state south of Springfield is Belleville, with 42,000 residents. It is located in the Metro East region of Greater St. Louis, the second-most populous urban area in Illinois with over 700,000 residents. Other major urban areas include the Peoria metropolitan area, Rockford metropolitan area, Champaign–Urbana metropolitan area (home to the University of Illinois), Springfield metropolitan area, the Illinois portion of the Quad Cities area, and the Bloomington–Normal metropolitan area. ==Demographics==

The United States Census Bureau found that the population of Illinois was 12,812,508 in the 2020 United States census, moving from the fifth-largest state to the sixth-largest state (losing out to Pennsylvania). Illinois' population slightly declined in 2020 from the 2010 United States census by just over 18,000 residents and the overall population was quite higher than recent census estimates.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 the Chicago metropolitan area comprises only 9% of the land area of the state, it contains 65% of the state's residents, with 21.4% of Illinois' population living in the city of Chicago itself as of 2020. The five most populous counties in the state, as of 2024, are Cook (5,182,617), DuPage (937,142), Lake (718,604), Will (708,583), and Kane (520,997), all located in the Chicago metropolitan area. While the state's population has declined in recent years, according to the 2020 census, these losses do not arise from the Chicago metro area; rather the declines are from the Downstate counties. As of the 2020 census, the state's geographic mean center of population is located at 41° 18′ 43″N 88° 22 23″W in Grundy County, about six miles northwest of Coal City. Illinois is the most racially and ethnically diverse state in the Midwestern United States. By several metrics, including racial and ethnic background, religious affiliation, and percentage of rural and urban divide, Illinois is the most representative of the larger demography of the United States. Race and ethnicity 2024 American Community Survey According to 2024 U.S. Census Bureau estimates (with Hispanics allocated amongst the various racial groups), Illinois' population was 60.2% White, 13.2% Black or African American, 0.8% Native American or Alaskan Native, 6.4% Asian, 0.1% Pacific Islander, 8.7% Some Other Race, and 10.7% from two or more races. The white population continues to remain the largest racial category in Illinois. Under this methodology, Hispanics are allocated amongst the various racial groups and primarily identify as Some Other Race (43.0%) or Multiracial (35.6%) with the remainder identifying as White (16.0%), Black (1.5%), American Indian and Alaskan Native (3.7%), Asian (0.3%), and Hawaiian and Pacific Islander (0.1%). Hispanic Americans If treated as a separate category, Hispanics are the largest minority group in Illinois, making up nearly a fifth of the population. About 75% of the state's Hispanic population is Mexican-American, numbering 1,794,369 and making up 14.3% of the total population of the state. Illinois is home to the largest population of Mexican descent in the US outside of the Western United States. The second largest Hispanic group in Illinois are Puerto Ricans, numbering 211,676 and making up 9% of the Hispanic population and 1.7% of the total population. The state is also home to significant Central American and South American communities, including 44,373 Guatemalan-Americans, 41,047 Ecuadorian-Americans, and 42,101 Colombian-Americans. Hispanics are the second fastest growing demographic in Illinois after Asians, growing by 15% between 2010 and 2020, while the overall population of the state declined. The vast majority of Hispanics in Illinois live in Chicago or the surrounding suburbs, with 786,464 Hispanics living in the city of Chicago itself, making up nearly a third of the city's population. Many large suburbs of Chicago, including Aurora, Berwyn, Cicero, and Elgin, have either a majority or plurality Hispanic population. The county with the highest share of Hispanic residents in the state, at 33.5% of the population, is Kane County, located on the western edge of the Chicago suburbs and including the cities of Elgin and Aurora. Hispanics have the lowest per-capita income of any major ethnic or racial group in Illinois, at $28,541. While those of Hispanic ethnicity are not distinguished between total and partial Hispanic origin, 2021 estimates show that almost 10% of the state's Hispanic population also reported a non-Spanish European ancestry, with this group making up 1.7% of the state's total population. African-Americans Black Americans form the second largest minority group in Illinois. In 2023, 1,922,259 Illinoisans identified as Black alone or in combination, making up 15.3% of the states population. Of this population, 1,643,638 (13.1%) are non-Hispanic Black alone, while 28,321 identify as Afro-Latino, and 250,300 identify as Black in combination with any other race. While most of the state's Black population identifies as African-American, there are also 45,393 people of West Indian descent and 43,911 of Nigerian descent in the state. A majority of the state's Black population resides in the Chicago metropolitan area, with 42% living in Chicago itself. According to a study from the Brookings Institution, the Chicago area has the third highest level of black-white residential segregation in the United States. Outside of Chicagoland, urban areas in Southern and Central Illinois, including the Metro East, Peoria, Springfield, and Decatur also have significant Black populations. The counties with the highest share of Black residents in Illinois are Pulaski and Alexander County, located at the southern tip of the state along the banks of the Ohio and Mississippi rivers in the region known as "Little Egypt", with Black residents making up 32% of the population in both counties. The per-capita income of Black residents, at $30,295, is the second lowest of all major ethnic or racial groups in the state, after Hispanics of any race. However, Black Illinoisans have the highest overall poverty rate of all groups in the state, at 23%. Illinois has a long history of milestones regarding African American involvement in politics. It was the first state to elect a Black person to the U.S. House of Representatives in the post-reconstruction era, with the election of Oscar De Priest in 1928. It was also the first state to elect a Black woman to the US Senate, with the election of Carol Moseley Braun in 1992. Illinois senator Barack Obama would become the first Black president of the United States following his victory in the 2008 presidential election. Asian-Americans The third largest minority group in Illinois are Asian-Americans. In 2023, 894,048 Illinoisans identified as being Asian alone or in combination, making up 7.1% of the state's population. 756,661 identified as Asian alone, making up 6.0% of the population. The largest specific Asian groups in the state are Indian (277,961), Filipino (184,508), Chinese (160,880), Korean (67,452), and Pakistani (50,508). About 85% of the state's Asian-American population identifies as Asian alone, while 15% identify as multiracial. Illinoisans of South Asian ancestry are significantly less likely than other Asian-Americans in the state to report multiracial ancestry, with 94% of Indian-Americans and 90% of Pakistani-Americans in the state identifying as Asian alone, compared to 82% of Chinese-American residents, 73% of Filipino-American residents, and only 44% of the state's 33,000 Japanese-American residents. Suburban DuPage County has the highest share of Asian residents in the state, at 14.7%. While Asians aren't the majority in any municipality within Illinois, they make up a significant share of the population (between 20 and 40%) in multiple western and northern suburbs of Chicago, including Naperville, Schaumburg, Hoffman Estates, Skokie, Niles, and Morton Grove. Additionally, the Chicago community area of Armour Square, which includes the city's Chinatown neighborhood, is majority Asian at 63.7% of the population. Asian residents have the highest per-capita income of any major ethnic or racial group in the state, at $54,122, and the second lowest poverty rate, after non-Hispanic whites, at 10.4%. Illinois senator Tammy Duckworth, of Thai descent, is one of only three Asian Americans currently serving in the US Senate. Native Americans In 2023, 271,494 Illinoisans identified as Native American alone or in combination, making up 2.2% of the state's population. 184,155 Illinoisans identified as Native American in combination with any other race, while 87,339 identified as being Native American alone. Over 80% of the state's Native American population also identified as being Hispanic or Latino, with only 12,385, or 0.1% of the population, identifying as non-Hispanic Native American alone. The largest non-Latin American Indigenous groups in the state were Blackfeet (8,674) and Navajo (3,950). Pacific Islanders The state has a very small number of Pacific Islanders, numbering 17,982 and making only 0.1% of the population in 2023. The majority of Pacific Islanders in the state identify as multiracial, with only 5,852 identifying as Pacific Islander alone. European-Americans In 2023, 7,260,529 Illinoisans identified as non-Hispanic white alone, making up 57.9% of the population. In the Chicago metro area, the white population is located mostly in suburban areas, with non-Hispanic white residents making up a majority of the population (between 53% and 75%) in every metropolitan county other than Cook County, while making up only 31.7% of the population in the city of Chicago itself. Within Chicago, there is significant racial segregation, with the white population concentrated primarily on the North Side of the city, while many predominantly African-American or Hispanic neighborhoods on the West Side and South Side of the city have almost no non-Hispanic white residents. The largest European ancestry reported in Illinois is German. 1,983,050 Illinoisans, or 15.8% of the total population, identify with German ancestry, making it the single largest ancestry group in the state. German ancestry predominates among the white population in every county in northern Illinois, as well as most counties in the southwestern part of the state, while English-Americans, making up 6.8% of Illinois' population, predominate in most of the southeastern counties. Illinois' Polish-American population of 761,948 is the highest out of any state. The state is also home to a significant population of other Eastern European ethnicities, also largely concentrated around the Chicago area, including 86,814 Russians, 83,679 Czechs, 71,279 Ukrainians, and 35,407 Croatians. Most Illinoisans who report any European ancestry identify with multiple ancestries. Those of partial descent make up the majority of most European ancestry groups in Illinois, including 58% of Polish-Americans, 68% of English-Americans, 69% of German-Americans, and 75% of Irish-Americans in the state. Of all European ancestries numbering over 50,000 in Illinois, those identifying solely with that ancestry are only a majority among the state's 71,279 Ukrainian-Americans, with two thirds of this group identifying as Ukrainian alone. Arab Americans The state is home to a significant Middle Eastern population, with 101,464 people (0.8% of the population) identifying as Arab.'''''''''' Oak Lawn, Palos Hills, and Hickory Hills, where they make up between 5–12% of the population. Illinois has the largest Palestinian population in the United States. According to census estimates, 19,255 Illinoisans have Palestinian ancestry, while other estimates place the population of Palestinian descent in the Chicago area as high as 85,000. Demographic Trends , 50% of Illinois's population younger than age 18 were minorities. This marks an increase from 2010, when 47% of children in the state were minorities, and 2000, when 41% were minorities. (Note: Children born to white Hispanics or to a sole full or partial minority parent are counted as minorities. Arabs are classified as white in census data.).

Cook County, which is home to Chicago, is the only majority-minority county within Illinois, with non-Hispanic whites making up a plurality of 40.4% of the population. Despite being the most ethnically diverse state in the Midwest, urban areas in Illinois have had a persistently high level of racial segregation, with a study from the Brookings Institution finding that the Chicago area has the third highest level of black-white residential segregation out of all major metropolitan areas in the United States.

Agriculture combine harvester on an Illinois farm; the company is headquartered in Moline, Illinois. 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. For example, Illinois had a harvest of 648.9 million bushels (17.7 million metric tons) in 2023, ahead of Iowa's production of 573 million bushels (15.6 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. Although Chicago may no longer be "Hog Butcher for the World", the Chicago area remains a global center for food manufacture and meat processing, 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 , one of twelve Federal Reserve Banks, at the heart of Chicago's financial center. 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. 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. Coal mining in central and southern Illinois was important in the late 19th and early 20th centuries. The 1909 Cherry Mine disaster was an underground fire that killed 259 miners in the third worst disaster in the history of American coal mining. After 1940 there was a slow decline in coal mining. 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. , Illinois was ranked third in recoverable coal reserves at producing mines in the nation. Nuclear power in Ogle County Worldwide nuclear power began in Illinois during 1942 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. 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. 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. University of Illinois 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. 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==

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.

In a 2020 study, Illinois was ranked as the 4th easiest state for citizens to vote in. State government in Springfield 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 executive branch is composed of six elected officers and their offices as well as numerous other departments. 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 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 (D) In modern national and state politics, 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 both presidential and congressional campaigns. Illinois's Democratic tendencies are mostly attributable to Cook County and Chicago, by far the state's largest county and city, respectively, which have long been strongly Democratic. The collar counties, affluent suburban counties that surround Cook County, historically voted Republican and helped keep the state competitive; however, they have swung toward the left in recent elections as the national Republican Party has become increasingly conservative, which has cemented Democratic dominance in state politics. Outside of the Chicago metropolitan area, the state's rural areas are heavily Republican. The dominance of the Chicago area in state elections is so overwhelming that it has influenced a secessionist movement in the downstate region. Illinois was long seen as a national bellwether, supporting the winner in every election in the 20th century, except for 1916 and 1976. Since the 1992 election, however, Illinois has trended more toward the Democratic Party and is part of the "blue wall" of states that have consistently voted Democratic in the last six presidential elections. In 2000, George W. Bush became the first Republican to win the presidency without carrying either Illinois or Vermont, with Donald Trump repeating the feat in 2016. Illinois has not elected a Republican to the Senate since Mark Kirk won in 2010; the last Republicans to hold statewide office were Governor Bruce Rauner and Lieutenant Governor Evelyn Sanguinetti, who both left office in 2019. 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. On December 7, 2011, former governor Rod Blagojevich was sentenced to 14 years in prison for allegations that he conspired to sell the vacated Senate seat left by President Barack Obama to the highest bidder. Blagojevich had earlier been 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 was then elected 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 Twelve 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, 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 Several families from Illinois have played particularly prominent roles in politics, in both the Republican Party earlier in the state's history but more recently the Democratic Party, gaining both statewide and national fame. Ingersoll The Ingersoll family of Illinois comprised a pair of brothers who held several prominent elected positions representing Illinois. • Ebon C. Ingersoll (1831–1879), Illinois State Representative 1856, U.S. Representative from Illinois 1864–71. Brother of Robert G. Ingersoll. • Robert G.

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 and 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. , 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 Urbana-Champaign, Loyola University Chicago, the Illinois Institute of Technology, DePaul University, University of Illinois Chicago, Illinois State University, Southern Illinois University Carbondale, and Northern Illinois University. 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 Urbana-Champaign is often ranked among the best engineering schools in the world and United States. 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. ==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 , one of the world's busiest 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. Highways in Rock Island The Interstate Highways in Illinois are all segments of the Interstate Highway System that are owned and maintained by the state. 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. Illinois has 13 primary (two-digit) interstates pass through it, more than any other state. 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. 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. Buses Due to its central location, Illinois sees numerous intercity bus services primarily connecting east and west. The Chicago Bus Station is the busiest intercity bus station in the state. The following carriers provide scheduled service: Amtrak Thruway, Barons Bus Lines, Burlington Trailways, Flixbus, Greyhound Lines, Indian Trails, Miller Transportation (Hoosier Ride), Peoria Charter Coach Company, Van Galder Bus Company, and Wisconsin Coach Lines. Railroads -owned Amtrak locomotives at Chicago Union Station 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 (including all six Class I railroads), making it the largest and most active rail hub in the country. Extensive heavy rail service 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, with one line extending into Kenosha, Wisconsin. The South Shore Line commuter service originates in Chicago and connects the state to Northwest Indiana. The Illinois Department of Transportation (IDOT) has programmed several new passenger rail routes to serve the state. These include the Chicago-Moline route (to be operated by Amtrak) and the Chicago-Rockford route (to be operated by Metra). A route between Chicago and Peoria was accepted into the Federal Railroad Administration's (FRA) Corridor Identification and Development Program and is undergoing studies. Waterways 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. The Illinois International Port District operates the Port of Chicago, which is located on Lake Michigan at the mouth of the Calumet River. It is the start point of the Illinois Waterway, which is series of rivers that allow for commercial shipping between the Great Lakes and the Mississippi River. The Illinois Waterway also consists of the Chicago Sanitary and Ship Canal, which connects the Chicago River with the Des Plaines River and replaced the Illinois and Michigan Canal. The Chicago River hosts many tourist and commuter boat routes such as the Chicago River Architecture Tours and the Chicago Water Taxi. == See also ==
