Illinois
From Wikinvestor
Illinois is a state of the United States of America, the 21st to be admitted to the Union. Illinois is the most populous and demographically diverse Midwestern state and the fifth most populous state in the nation. With Chicago in the northeast, small industrial cities and great agricultural productivity in central and western Illinois, and natural resources like coal, timber, and petroleum in the south, Illinois has a broad economic base. Illinois is an important transportation hub; the Port of Chicago connects the Great Lakes to the Mississippi River via the Illinois River. Illinois is often viewed as a microcosm of the United States; an Associated Press analysis of 21 demographic factors found Illinois the "most average state,"[6] while Peoria has long been a proverbial social and cultural bellwether.
Approximately 66% of the population resides in the northeastern corner of the state, primarily within the city of Chicago and the surrounding metropolitan areas.
With a population near 40,000 between 1300 and 1400 AD, the Mississippian city of Cahokia, in what is now southern Illinois, was the largest city within the future United States until it was surpassed by New York City between 1790 and 1800. About 2,000 Native American hunters and a small number of French villagers inhabited the Illinois area at the time of the American Revolution. American settlers began arriving from Kentucky in the 1810s; they achieved statehood in 1818. The future metropolis of Chicago was founded in the 1830s on the banks of the Chicago River, one of the only natural harbors on southern Lake Michigan.[8] Railroads and John Deere's invention of the self-scouring steel plow made central Illinois' rich prairie into some of the world's most productive and valuable farmlands, attracting immigrant farmers from Germany and Sweden. Northern Illinois provided major support for Illinoisans Abraham Lincoln and Ulysses S. Grant during the American Civil War. By 1900, the growth of industry in northern cities and coal mining in central and southern areas attracted immigrants from Eastern and Southern Europe, and made the state a major arsenal in both world wars. African-Americans migrating to Chicago from the rural South formed a large and important community, which created the city's famous jazz and blues cultures.
Geography

The Northeastern border of Illinois is Lake Michigan. Its eastern border with Indiana is all of the land west of the Wabash River, and a north-south line above Post Vincennes, or 87° 31′ 30″ west longitude. Its northern border with Wisconsin is fixed at 42° 30' north latitude. Its western border with Missouri and Iowa is the Mississippi River. Its southern border with Kentucky is the Ohio River. Illinois also borders Michigan, but only via a water boundary in Lake Michigan.
Though Illinois lies entirely in the Interior Plains, it has three major geographical divisions. The first is Northern Illinois, dominated by the Chicago metropolitan area, including the city of Chicago, its suburbs, and the adjoining exurban area into which the metropolis is expanding. As defined by the federal government, the Chicago metro area includes a few counties in Indiana and Wisconsin and stretches across much of northeastern Illinois. It is a cosmopolitan city, densely populated, industrialized, and settled by a wide variety of ethnic groups. The city of Rockford, the second largest metropolitan area and the state's third largest city generally sits along Interstates 39 and 90 some 75 miles northwest of Chicago.
Southward and westward, the second major division is Central Illinois, an area of mostly flat prairie. Known as the Heart of Illinois, it is characterized by small towns and mid-sized cities. The western section (west of the Illinois River) was originally part of the Military Tract of 1812 and forms the distinctive western bulge of the state. Agriculture, particularly corn and soybeans, as well as educational institutions and manufacturing centers, figure prominently. Cities include Peoria—the third largest metropolitan area in Illinois at 370,000—Springfield—the state capital—Quincy, Decatur, Bloomington-Normal and Champaign-Urbana. Though the Illinois Quad Cities are geographically almost at the same latitude as Chicago, they are often grouped in Central Illinois due to economic, political, and cultural ties to this region.
The third division is Southern Illinois, comprising the area south of U.S. Route 50, and including Little Egypt, near the juncture of the Mississippi River and Ohio River. This region can be distinguished from the other two by its warmer climate, different mix of crops (including some cotton farming in the past), more rugged topography (the southern tip is unglaciated with the remainder glaciated during the Illinoian Stage and earlier ages), as well as small-scale oil deposits and coal mining. The area is a little more populated than the central part of the state with the population centered in two areas. First, the Illinois suburbs of St. Louis comprise the second most populous metropolitan area in Illinois with nearly 600,000 inhabitants, and are known collectively as the Metro-East. The second area is Williamson County, Jackson County, Franklin County, Saline County and Perry County. It is home to around 210,000 residents.
The region outside of the Chicago Metropolitan area is often described as "downstate Illinois". However, residents of central and southern Illinois view their regions as geographically and culturally distinct, and do not necessarily use this term.
In extreme northwestern Illinois, the Driftless Zone, 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). The highest structure in Illinois is the Sears Tower with a roof elevation of approximately 2,034 feet (620 m) above sea level. [Chicago elevation (580 ft) + tower height (1454 ft) = 2034.]
The floodplain on the Mississippi River from Alton to the Kaskaskia River is the American Bottom, and is the site of the ancient city of Cahokia. It was a region of early German settlement, as well as the site of the first state capital, at Kaskaskia which is separated from the rest of the state by the Mississippi River.
A portion of Southeastern Illinois is part of the extended Evansville, Indiana Metro Area, commonly referred to as the Tri-State with Indiana and Kentucky. Seven Illinois counties are in the area.
Climate
Because of its nearly 400 miles (644 km) length and mid-continental situation, Illinois has a widely varying climate. Most of Illinois has a humid continental climate (Koppen climate classification Dfa), with hot, humid summers and cool to cold winters. The southernmost part of the state, from about Carbondale southward, borders on 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).[16] The all time high temperature was 117 °F (47 °C), recorded on 14 July 1954, at East St. Louis, Illinois, while the all time low temperature was −36 °F (−38 °C), recorded on 05 January 1999, at Congerville, Illinois.
Illinois averages around 50 days of thunderstorm activity a year which put it somewhat above average for 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 5 tornadoes per 10,000 square miles (30,000 km2) annually. The deadliest tornado on record in the nation occurred largely in Illinois. The Tri-State Tornado of 1925 killed 695 people in three states; 613 of the victims lived in Illinois.
Demographics
As of 2006, Illinois has an estimated population of 12,831,970, which is an increase of 65,200 from the prior year and an increase of 412,323, or 3.3%, since the year 2000. This includes a natural increase since the last census of 481,799 people (that is 1,138,398 births minus 656,599 deaths) and a decrease due to net migration of 71,456 people out of the state. Immigration from outside the United States resulted in an increase of 402,257 people, and migration within the country produced a loss of 473,713 people. As of 2004 there were 1,682,900 foreign-born (13.3%).
At the northern edge of the state on Lake Michigan lies Chicago, the nation's third largest city. In 2000, 23.3% of the population lived in the city of Chicago, 43.3% in Cook County and 65.6% the counties of the Chicago metro area; Will, DuPage, Kane, Lake, and McHenry Counties as well as Cook County. The rest of the population lives in the smaller cities and in the rural areas that dot the state's plains.
According to 2005 census, the racial distributions are as follows: 65.6% White American, 15.1% African-American, 3.9% are Asian, 2% other, and the remaining 13.2% are Hispanics or Latino of any race. Nearly three in ten whites in Illinois claimed at least partial German ancestry on the Census. African-Americans are present in large numbers in the city of Chicago, East St. Louis, and the southern tip of the state. Residents citing American and British ancestry are especially concentrated in the southeastern part of the state. Metropolitan Chicago has the greatest numbers of people of Irish, Mexican, and Polish ancestry.
7.1% of Illinois' population was reported as under age 5, 26.1% under age 18, and 12.1% were 65 or older. Females made up approximately 51% of the population.
According to the 2000 U.S. Census, 10.85% of the population aged 5 and older speak Spanish at home, while 1.60% speak Polish.
