The Illinois River is a principal tributary of the Mississippi River 273 miles long, in the U. S. state of Illinois. The river drains a large section of central Illinois, with a drainage basin of 28,756.6 square miles. The drainage basin extends into Wisconsin, a small area of southwestern Michigan; this river was important among Native Americans and early French traders as the principal water route connecting the Great Lakes with the Mississippi. The French colonial settlements along the rivers formed the heart of the area known as the Illinois Country. After the construction of the Illinois and Michigan Canal and the Hennepin Canal in the 19th century, the role of the river as link between Lake Michigan and the Mississippi was extended into the era of modern industrial shipping, it now forms the basis for the Illinois Waterway. The Illinois River is formed by the confluence of the Kankakee River and the Des Plaines River in eastern Grundy County 10 miles southwest of Joliet; this river flows west across northern Illinois, passing Morris and Ottawa, where it is joined by the Mazon River and Fox River.
At LaSalle, the Illinois River is joined by the Vermilion River, it flows west past Peru, Spring Valley. In southeastern Bureau County it turns south at an area known as the "Great Bend", flowing southwest across western Illinois, past Lacon and downtown Peoria, the chief city on the river. South of Peoria, the Illinois River goes by East Peoria and Creve Coeur, Pekin, Illinois, in Tazewell County, Illinois, it is joined by the Mackinaw River and passes through the Chautauqua National Wildlife Refuge. Across from Havana, the Illinois is joined by the Spoon River coming from Fulton County and across from Browning, it is joined by the Sangamon River, which passes through the state capital, Illinois; the La Moine River flows into it five miles southwest of Beardstown, south of Peoria and Pekin and north of Lincoln and Springfield. Near the confluence of the Illinois with the La Moine River, it turns south, flowing parallel to the Mississippi across southwestern Illinois. Macoupin Creek joins the Illinois on the border between Greene and Jersey counties 15 miles upstream from the confluence with the Mississippi.
For the last 20 miles of its course, the Illinois is separated from the Mississippi River by only about five miles, by a peninsula of land that makes up Calhoun County. The Illinois joins the Mississippi near Grafton 25 miles northwest of downtown St. Louis and about 20 miles upstream from the confluence of the Missouri River and the Mississippi. South of Hennepin, the Illinois River is following the ancient channel of the Mississippi River; the Illinoian Stage, about 300,000 to 132,000 years ago, blocked the Mississippi near Rock Island, diverting it into its present channel. After the glacier melted, the Illinois River flowed into the ancient channel; the Hennepin Canal follows the ancient channel of the Mississippi upstream of Rock Island. The modern channel of the Illinois River was shaped in a matter of days by the Kankakee Torrent. During the melting of the Wisconsin Glacier about 10,000 years ago, a lake formed in present-day Indiana, comparable to one of the modern Great Lakes; the lake formed behind the terminal moraine of a substage of that glacier.
Melting ice to the north raised the level of the lake so that it overflowed the moraine. The dam burst, the entire volume of the lake was released in a short time a few days; because of the manner of its formation, the Illinois River runs through a deep canyon with many rock formations. It has an "underutilized channel", one far larger than would be needed to contain any conceivable flow in modern times. Flooding along the Illinois River The Illinois River valley was one of the strongholds of the Illinois Confederation of Native Americans; the French first met the natives here in 1673. The first European settlement in the state of Illinois was the Jesuit mission founded in 1675 by Father Jacques Marquette on the banks of the Illinois across from Starved Rock at the Grand Village of the Illinois. Marquette wrote of the river, “We have seen nothing like this river that we enter, as regards its fertility of soil, its prairies and woods. There are many small rivers; that on which we sailed is wide and still, for 65 leagues."In 1680, René-Robert Cavelier, Sieur de La Salle built the first fort in Illinois, Ft. St. Louis, at Starved Rock.
It was relocated to the present site of Creve Coeur, near Peoria, where the Jesuits relocated. The Peoria Riverfront Museum contains a gallery, "Illinois River Encounter," that attempts to interpret the museum through an aquarium tank and displays of the river's geology, social history and commercial use. From 1905 to 1915, more freshwater fish were harvested from the Illinois River than from any other river in the United States except for the Columbia River; the Illinois River was once a major source of mussels for the shell button industry. Overfishing, habitat loss from heavy siltation, water pollution have eliminated most commercial fishing except for a small mussel harvest to provide shells to seed pearl oysters overseas, it is commercially fished downstream of the Rt. 89 bridge at Spring Valley. However, an infestation of invasive Asian Carp has crowded out many game fish in the river; the Illinois River is still an important sports fishing waterway with a good sauger fishery. The Illinois forms part of a modern waterway that connects the Great
Morgan County, Illinois
Morgan County is a county located in the U. S. state of Illinois. According to the 2010 census, it had a population of 35,547, its county seat is Jacksonville. Morgan County is part of the Jacksonville, IL Micropolitan Statistical Area, included in the Springfield-Jacksonville-Lincoln, IL Combined Statistical Area. Morgan County was formed in 1823 out of Sangamon Counties, it was named in honor of General Daniel Morgan, who defeated the British at the Battle of Cowpens in the American Revolutionary War. General Morgan was serving under General Nathanael Greene at Cowpens. Jacksonville was established by European Americans on a 160-acre tract of land in the center of Morgan County in 1825, two years after the county was founded; the founders of Jacksonville, Illinois consisted of settlers from New England. These people were "Yankee" settlers, to say they were descended from the English Puritans who settled New England in the 1600s, they were part of a wave of New England farmers who headed west into what was the wilds of the Northwest Territory during the early 1800s.
Most of them arrived as a result of the completion of the Erie Canal and the end of the Black Hawk War. The Yankee migration to Illinois was a result of several factors, one of, the overpopulation of New England; the old stock Yankee population had large families bearing up to ten children in one household. Most people were expected to have their own piece of land to farm, due to the massive and nonstop population boom, land in New England became scarce as every son claimed his own farmstead; as a result, there was not enough land for every family to have a self-sustaining farm, Yankee settlers began leaving New England for the Midwestern United States. When they arrived in what is now Jacksonville there was nothing but dense virgin forest and wild prairie, the "Yankee" New Englanders laid out farms, constructed roads, erected government buildings and established post routes, they brought with them many of their Yankee New England values, such as a passion for education, establishing many schools as well as staunch support for abolitionism.
They were members of the Congregationalist Church though some were Episcopalian. Due to the second Great Awakening some of them had converted to Methodism and Presbyterianism while some others became Baptist, before moving to what is now Jacksonville. Jacksonville, like some other parts of Illinois, would be culturally continuous with early New England culture for most of its early history.</ref> According to the US Census Bureau, the county has a total area of 572 square miles, of which 569 square miles is land and 3.5 square miles is water. Average temperatures in the county seat of Jacksonville range from a low of 15 °F in January to a high of 87 °F in July. Average monthly precipitation ranged from 1.35 inches in January to 4.86 inches in May.

There were 15,515 housing units at an average density of 27.3 per square mile.
The racial makeup of the county was 90.9% white, 6.0% black or African American, 0.5% Asian, 0.2% American Indian, 0.8% from other races, 1.6% from two or more races. Those of Hispanic or Latino origin made up 2.0% of the population. In terms of ancestry, 25.9% were German, 21.6% were American, 15.4% were Irish, 14.5% were English. Those citing "American" ancestry in Morgan County, Illinois are of overwhelmingly English extraction, in many cases going back to colonial New England, however most English Americans identify as having "American" ancestry because their roots have been in North America for so long, in many cases since the early sixteen hundreds. Of the 14,104 households, 28.3% had children under the age of 18 living with them, 47.4% were married couples living together, 11.2% had a female householder with no husband present, 37.2% were non-families, 31.5% of all households were made up of individuals.

Springfield is the capital of the U. S. state of Illinois and the county seat of Sangamon County. The city's population of 116,250 as of the 2010 U. S. Census makes it the state's sixth most populous city, it is the largest city in central Illinois. As of 2013, the city's population was estimated to have increased to 117,006, with just over 211,700 residents living in the Springfield Metropolitan Statistical Area, which includes Sangamon County and the adjacent Menard County. Present-day Springfield was settled by European Americans in the late 1810s, around the time Illinois became a state; the most famous historic resident was Abraham Lincoln, who lived in Springfield from 1837 until 1861, when he went to the White House as President. Major tourist attractions include multiple sites connected with Lincoln including his presidential library and museum, his home, his tomb at Oak Ridge Cemetery; the capital is centrally located within the state. The city lies in a plain near the Sangamon River. Lake Springfield, a large artificial lake owned by the City Water, Light & Power company, supplies the city with recreation and drinking water.
Weather is typical for middle latitude locations, with hot summers and cold winters. Spring and summer weather is like that of most midwestern cities. Tornadoes hit the Springfield area in 1957 and 2006; the city governs the Capital Township. The government of the state of Illinois is based in Springfield. State government entities include the Illinois General Assembly, the Illinois Supreme Court and the Office of the Governor of Illinois. There are three private high schools in Springfield. Public schools in Springfield are operated by District No. 186. Springfield's economy is dominated by government jobs, plus the related lobbyists and firms that deal with the state and county governments and justice system, health care and medicine. Springfield was named "Calhoun", after Senator John C. Calhoun of South Carolina; the land that Springfield now occupies was settled first by trappers and fur traders who came to the Sangamon River in 1818. The first cabin was built by John Kelly, it was located at what is now the northwest corner of Jefferson Street.
In 1821, Calhoun was designated as the county seat of Sangamon County due to fertile soil and trading opportunities. Settlers from Kentucky and North Carolina came to the developing city. By 1832, Senator Calhoun had fallen out of the favor with the public and the town renamed itself as Springfield after Springfield, Massachusetts. At that time, the New England city was known for industrial innovation, concentrated prosperity, the Springfield Armory. Kaskaskia was the first capital of the Illinois Territory from its organization in 1809, continuing through statehood in 1818, through the first year as a state in 1819. Vandalia was the second state capital of Illinois from 1819 to 1839. Springfield became the third and current capital of Illinois in 1839; the designation was due to the efforts of Abraham Lincoln and his associates. The Potawatomi Trail of Death passed through here in 1838, as the Native Americans were forced west to Indian Territory by the government's Indian Removal policy. Lincoln arrived in the Springfield area when he was a young man in 1831, though he did not live in the city until 1837.
He spent the ensuing six years in New Salem, where he began his legal studies, joined the state militia and was elected to the Illinois General Assembly. In 1837 Lincoln spent the next 24 years as a lawyer and politician. Lincoln delivered his Lyceum address in Springfield, his farewell speech when he left for Washington is a classic in American oratory. Winkle examines the historiography concerning the development of the Second Party System and applies these ideas to the study of Springfield, a strong Whig enclave in a Democratic region, he chiefly studied poll books for presidential years. The rise of the Whig Party took place in 1836 in opposition to the presidential candidacy of Martin Van Buren and was consolidated in 1840. Springfield Whigs tend to validate several expectations of party characteristics as they were native-born, either in New England or Kentucky, professional or agricultural in occupation, devoted to partisan organization. Abraham Lincoln's career reflects the Whigs' political rise, but by the 1840s, Springfield began to be dominated by Democratic politicians.
Waves of new European immigrants changed the city's demographics and became aligned with the Democrats. By the 1860 presidential election, Lincoln was able to win his home city. Winkle examines the impact of migration on political participation in Springfield during the 1850s. Widespread migration in the 19th-century United States produced frequent population turnover within Midwestern communities, which influenced patterns of voter turnout and office-holding. Examination of the manuscript census, poll books, office-holding records reveals the effects of migration on the behavior and voting patterns of 8,000 participants in 10 elections in Springfield. Most voters were short-term residents who participated in only one or two elections during the 1850s. Fewer than 1% of all voters participated in all 10 elections. Instead of producing political instability, rapid turnover enhanced the influence of the more stable residents. Migration was selective by age, occupation and birthplace. Longer-term or persistent voters, as he terms them, tended to be wealthier, more skilled, more native-born, more stable than non-persisters.

Jacksonville is a city in Morgan County, United States. The population was 19,446 at the 2010 census, it is the county seat of Morgan County. It is home to Illinois College, MacMurray College, Illinois School for the Deaf, the Illinois School for the Visually Impaired. Jacksonville is the principal city of the Jacksonville Micropolitan Statistical Area, which includes all of Morgan and Scott counties. Jacksonville was established by European Americans on a 160-acre tract of land in the center of Morgan County in 1825, two years after the county was founded; the founders of Jacksonville, Illinois consisted of settlers from New England. These people were "Yankee" settlers, to say they were descended from the English Puritans who settled New England in the 1600s, they were part of a wave of New England farmers who headed west into what was the wilds of the Northwest Territory during the early 1800s.

Jacksonville, like some other parts of Illinois, would be culturally continuous with early New England culture for most of its early history.</ref>The town grew at a rapid rate, a town square was developed. In 1829, the Presbyterian Reverend John M. Ellis worked to found a new "seminary of learning" in the new state of Illinois. A group of Congregational students at Yale University heard about his plans and headed westward to establish the new school; these students were a part of the famous "Yale Bands," groups of students who established several colleges in the frontier, what is now the Midwest. Illinois College was one of the first institutions of higher learning in the Midwest; the college stimulated the growth of Jacksonville. A new courthouse was built on the square, churches were constructed, railroads were planned, stores and taverns were built.
By 1834, Jacksonville had the largest population of any city in the state of Illinois, vastly outnumbering Chicago. In the 1830s, the town was on the path of Native Americans who were being forcibly removed by the federal government to west of the Mississippi; the Potawatomi passed through here in 1838 on what they called their Trail of Death as they were forced from their traditional homelands to the dry and barren Indian Territory to the west. Jacksonville's education complex and standing in the state was developed by the establishment of state institutions: the Illinois School for the Deaf and the Illinois School for the Visually Impaired; the Illinois Conference Female Academy was founded for education for girls. By 1850, Illinois College had issued Illinois' first college degrees and opened the first medical school in the state; because of this, Jacksonville earned the nickname of "Athens of the West."In 1851, Illinois opened its first state mental hospital in Jacksonville. Now named the Jacksonville Developmental Center, this facility serves developmentally challenged individuals.
The attorney Abraham Lincoln had legal business in Jacksonville acting either as co-counsel or opposing counsel with David A. Smith, a Jacksonville resident. In what is now Central Park Plaza, Lincoln delivered a strong antislavery speech on September 6, 1856 in support of the presidential campaign of John C. Frémont, lasting over two hours. A mural depicting the event has been painted on the side of a building at the southwest corner of the Park. During the antebellum years, Jacksonville was a major stopping point on the historic Underground Railroad, as refugee slaves moved north to freedom, many going into Canada; the city has an annual commemoration of the Civil War, with a reenactment named for the late Jacksonville resident U. S. Army General Benjamin Grierson; this event has been suspended. In 1911 as part of the progressive movement, Jacksonville adopted the city commission form of government, the first mayor being George W. Davis. In the summer of 1965, in order to keep up with customer demand for records by the Beatles, the wildly popular English band, Capitol Records opened a vinyl record pressing plant on the western outskirts of Jacksonville, at 1 Capitol Way.
The plant produced a number of collectible pressings. This plant served the Capitol Records Club, producing vinyl LPs and audiocassettes, CDs, DVDs of a number of artists. At its peak, operating as EMI Records, the plant employed over 1,000 workers, it was a significant location in the music industry. For example, all seven albu
2010 United States Census
The 2010 United States Census is the twenty-third and most recent United States national census. National Census Day, the reference day used for the census, was April 1, 2010; the census was taken via mail-in citizen self-reporting, with enumerators serving to spot-check randomly selected neighborhoods and communities. As part of a drive to increase the count's accuracy, 635,000 temporary enumerators were hired; the population of the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census. This was the first census in which all states recorded a population of over half a million, as well as the first in which all 100 largest cities recorded populations of over 200,000; as required by the United States Constitution, the U. S. census has been conducted every 10 years since 1790. The 2000 U. S. Census was the previous census completed. Participation in the U. S. Census is required by law in Title 13 of the United States Code. On January 25, 2010, Census Bureau Director Robert Groves inaugurated the 2010 Census enumeration by counting World War II veteran Clifton Jackson, a resident of Noorvik, Alaska.
More than 120 million census forms were delivered by the U. S. Post Office beginning March 15, 2010; the number of forms mailed out or hand-delivered by the Census Bureau was 134 million on April 1, 2010. Although the questionnaire used April 1, 2010 as the reference date as to where a person was living, an insert dated March 15, 2010 included the following printed in bold type: "Please complete and mail back the enclosed census form today." The 2010 Census national mail participation rate was 74%. From April through July 2010, census takers visited households that did not return a form, an operation called "non-response follow-up". In December 2010, the U. S. Census Bureau delivered population information to the U. S. President for apportionment, in March 2011, complete redistricting data was delivered to states. Identifiable information will be available in 2082; the Census Bureau did not use a long form for the 2010 Census. In several previous censuses, one in six households received this long form, which asked for detailed social and economic information.
The 2010 Census used only a short form asking ten basic questions: How many people were living or staying in this house, apartment, or mobile home on April 1, 2010? Were there any additional people staying here on April 1, 2010 that you did not include in Question 1? Mark all that apply: Is this house, apartment, or mobile home – What is your telephone number? What is Person 1's name? What is Person 1's sex? What is Person 1's age and Person 1's date of birth? Is Person 1 of Hispanic, Latino, or Spanish origin? What is Person 1's race? Does Person 1 sometimes live or stay somewhere else? The form included space to repeat all of these questions for up to twelve residents total. In contrast to the 2000 census, an Internet response option was not offered, nor was the form available for download. Detailed socioeconomic information collected during past censuses will continue to be collected through the American Community Survey; the survey provides data about communities in the United States on a 1-year or 3-year cycle, depending on the size of the community, rather than once every 10 years.
A small percentage of the population on a rotating basis will receive the survey each year, no household will receive it more than once every five years. In June 2009, the U. S. Census Bureau announced. However, the final form did not contain a separate "same-sex married couple" option; when noting the relationship between household members, same-sex couples who are married could mark their spouses as being "Husband or wife", the same response given by opposite-sex married couples. An "unmarried partner" option was available for couples; the 2010 census cost $13 billion $42 per capita. Operational costs were $5.4 billion under the $7 billion budget. In December 2010 the Government Accountability Office noted that the cost of conducting the census has doubled each decade since 1970. In a detailed 2004 report to Congress, the GAO called on the Census Bureau to address cost and design issues, at that time, had estimated the 2010 Census cost to be $11 billion. In August 2010, Commerce Secretary Gary Locke announced that the census operational costs came in under budget.
Locke credited the management practices of Census Bureau director Robert Groves, citing in particular the decision to buy additional advertising in locations where responses lagged, which improved the overall response rate. The agency has begun to rely more on questioning neighbors or other reliable third parties when a person could not be reached at home, which reduced the cost of follow-up visits. Census data for about 22% of U. S. househol
1940 United States Census
The Sixteenth United States Census, conducted by the Census Bureau, determined the resident population of the United States to be 132,164,569, an increase of 7.3 percent over the 1930 population of 123,202,624 people. The census date of record was April 1, 1940. A number of new questions were asked including where people were 5 years before, highest educational grade achieved, information about wages; this census introduced sampling techniques. Other innovations included a field test of the census in 1939; this was the first census in which every state had a population greater than 100,000. The 1940 census collected the following information: In addition, a sample of individuals were asked additional questions covering age at first marriage and other topics. Full documentation on the 1940 census, including census forms and a procedural history, is available from the Integrated Public Use Microdata Series. Following completion of the census, the original enumeration sheets were microfilmed; as required by Title 13 of the U.
S. Code, access to identifiable information from census records was restricted for 72 years. Non-personally identifiable information Microdata from the 1940 census is available through the Integrated Public Use Microdata Series. Aggregate data for small areas, together with electronic boundary files, can be downloaded from the National Historical Geographic Information System. On April 2, 2012—72 years after the census was taken—microfilmed images of the 1940 census enumeration sheets were released to the public by the National Archives and Records Administration; the records are indexed only by enumeration district upon initial release.

Illinois is a state in the Midwestern and Great Lakes region of the United States. It has the fifth largest gross domestic product, the sixth largest population, the 25th largest land area of all U. S. states. Illinois is 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, natural resources such as coal and petroleum in the south, Illinois has a diverse economic base, is a major transportation hub. Chicagoland, Chicago's metropolitan area, encompasses over 65% of the state's population; 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 Waterway to the Illinois River. The Mississippi River, the Ohio River, 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, located in the central part of the state. Although today's Illinois' largest population center is in its northeast, the state's European population grew first in the west as the French settled the vast Mississippi of the Illinois Country of New France. Following the American Revolutionary War, American settlers began arriving from Kentucky in the 1780s via the Ohio River, 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 founded 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 made transportation between the Great Lakes and the Mississippi River valley faster and cheaper, 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 alpha-level city. Three U. S. presidents have been elected while living in Illinois: Abraham Lincoln, Ulysses S. Grant, 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, 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. "Illinois" is the modern spelling for the early French Catholic missionaries and explorers' name for the Illinois Native Americans, a name, spelled in many different ways in the early records. American scholars 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, plural of "man" is ireniwaki. The name Illiniwek has been said to mean "tribe of superior men", 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 in the Ottawa dialect, modified into ilinwe·.
The French borrowed these forms, changing the /we/ ending to spell it as -ois, a transliteration for its pronunciation in French of that time. The current spelling form, 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. 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 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 50-acre plaza larger than 35 football fields, 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 100 feet high, 951 feet long, 836 feet wide, covers 13.8 acres. It contains about 814,000 cubic yards of earth, it was topped by a structure thought to have measured about 105 feet in length and 48 feet in width, covered an area 5,000 square feet, been as much as 50 feet high, making its peak 150 feet above the level of the pl
