Illinois

Illinois is a state in the Midwestern region of the United States. It is the 5th most populous state and 25th largest state in terms of land area, and is often noted as a microcosm of the entire country. With Chicago in the northeast, small industrial cities and great agricultural productivity in central and northern Illinois, and natural resources like 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 other global ports from the Great Lakes, via the Saint Lawrence Seaway, to the Atlantic Ocean, as well as the Great Lakes to the Mississippi River, via the Illinois River. For decades, 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 politics.

Although today the state’s largest population center is around Chicago in the northern part of the state, the state’s European population grew first in the west, with French Canadians who settled along the Mississippi River, and gave the area the name, Illinois. After the American Revolutionary War established the United States, American settlers began arriving from Kentucky in the 1810s via the Ohio River, and the population grew from south to north. In 1818, Illinois achieved statehood. After construction of the Erie Canal increased traffic and trade through the Great Lakes, Chicago was founded in the 1830s on the banks of the Chicago River, at one of the few natural harbors on southern Lake Michigan. John Deere’s invention of the self-scouring steel plow turned Illinois’ rich prairie into some of the world’s most productive and valuable farmlands, attracting immigrant farmers from Germany and Sweden. Railroads carried immigrants to new homes, as well as being used to ship their commodity crops out to markets.

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 Chicago, who created the city’s famous jazz and blues cultures.

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 the only U.S. president born and raised in Illinois. Today, Illinois honors Lincoln with its official state slogan, Land of Lincoln, which has been displayed on its license plates since 1954. The Abraham Lincoln Presidential Library and Museum is located in the state capital of Springfield.

Illinois, showing major cities and roads

Illinois is located in the Midwest Region of the United States and is one of the eight states and Canadian Province of Ontario in the bi-national Great Lakes region of North America.

Boundaries

Illinois’ eastern border with Indiana consists of a north-south line at 87° 31′ 30″ west longitude in Lake Michiganat 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’ 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. Charles Mound, located in this region, has the state’s highest elevation above sea level at 1,235 feet (376 m). 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.

Charles Mound, the highest natural point in Illinois at 1235 feet, is located in the northwestern part of the state.

Divisions

Chicago on Lake Michigan is the third largest city in the United States.

The lowest elevation in the State is near Cairo and the confluence of the Ohio and Mississippi Rivers

Illinois has three major geographical divisions. Northern Illinois is dominated by 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 people. Chicago itself is a cosmopolitan city, densely populated, industrialized, and the transportation hub of the nation, and settled by a wide variety of ethnic groups. The city of Rockford, Illinois’ third largest city and center of the state’s fourth largest metropolitan area, sits along Interstates 39 and 90 some 75 miles (121 km) northwest of Chicago. The Cities region, located along the Mississippi River in northern Illinois, had a population of 381,342 in 2011.

The midsection of Illinois is a second major division, called Central Illinois. It is an area of mostly 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 Illinoisan 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 latitudinal defined divisions, all of the region outside of the Chicago Metropolitan area is often called “downstate” Illinois. This term is flexible, but is generally meant to mean everything outside 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 considered to be “downstate”.

Climate

Main article: Climate of Illinois

Illinois map of Köppen climate classification.

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 48 inches (1,219 mm) at the southern tip to around 35 inches (889 mm) in the northern portion of the state. Normal annual snowfall exceeds 38 inches (965 mm) in the Chicago area, while the southern portion of the state normally receives less than 14 inches (356 mm). The all-time high temperature was 117 °F (47 °C), recorded on July 14, 1954, at East St. Louis, while the all-time low temperature was −36 °F (−38 °C), and recorded on January 5, 1999, at Conger Ville. A temperature of -37 °F (-39 °C), was recorded on January 15, 2009, at Rochelle.

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 10,000 square miles (30,000 km2) annually. While tornadoes are no more powerful in Illinois than other states, the nation’s deadliest tornadoes on record have occurred largely in Illinois because it is the most populous state in Tornado Alley. The Tri-State Tornado of 1925 killed 695 people in three states; 613 of the victims died in Illinois. Other significant high-casualty tornadoes include the 1896 St. Louis – East St. Louis tornado, which killed 111 people in East St. Louis and a May 1917 tornado that killed 101 people in Charleston and Mattoon. Modern developments in storm forecasting and tracking have caused death tolls from tornadoes to decline dramatically, with the 1967 Belvidere – Oak Lawn tornado outbreak (58 fatalities) and 1990 Plainfield tornado (29 fatalities) standing out as exceptions. On November 18, 2013, tornadoes touched down and ripped through Washington, Illinois. There were seven fatalities.

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 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 59Springfield, 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 people.

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 area with about 215,000 people, and the Bloomington-Normal area with a combined population of over 165,000.

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, with 59.3 million domestic passengers annually, along with 11.4 million international passengers in 2008, O’Hare remains one of the two or three busiest airports in the world, and some years still ranks number one in total flights. It is a major hub for United Airlines and American Airlines, and a major airport expansion project is currently underway. Chicago Midway International Airport (MDW), which had been the busiest airport in the world until supplanted by O’Hare in 1962, is now the secondary airport in the Chicago metropolitan area. For a time in the late 1960s and 1970s, Midway was nearly vacant except for general aviation, but growth in the area, combined with political deadlock over the building of a new major airport in the region, has caused a resurgence for Midway. It is now a major hub for Southwest Airlines, and services many other airlines as well. Midway served 17.3 million domestic and international passengers in 2008.

Rail

Illinois Major Rail Network

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 track work on the Chicago–St. Louis line to bring the maximum speed up to 110 mph (180 km/h), 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. 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

Illinois is among many US states with a well-developed interstate highway system. Illinois has the distinction of having the most primary (two-digit) interstates pass through it among all the 50 states with 13 (with the new addition of Interstate 41 near Wisconsin), as well as the 3rd most interstate mileage behind California and Texas.

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

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.
