Cook County is the most populous county in the U.S. state of Illinois and the second-most-populous county in the United States, after Los Angeles County, California. More than 40 percent of all residents of Illinois live within Cook County. As of 2020,[update] the population was 5,275,541. The county seat is Chicago, the most populous city in Illinois and the third most populous city in the United States. The county is at the center of the Chicago metropolitan area.
Cook County was incorporated in 1831 and named for Daniel Pope Cook, an early Illinois statesman. It achieved its present boundaries in 1839. Within a century, the county recorded explosive population growth, going from a trading post village with a little over six hundred residents to four million, rivaling Paris by the Great Depression. During the first half of the 20th century it had the absolute majority of Illinois's population.
There are more than 800 local governmental units and nearly 130 municipalities located wholly or partially within Cook County, the largest of which is Chicago. The city is home to approximately 54 percent of the entire county's population.[5] The part of the county outside of the Chicago and Evanston city limits is divided into 29 townships; these often divide or share governmental services with local municipalities. Townships within Chicago were abolished in 1902 but are retained for real estate assessment purposes. Evanston Township was formerly coterminous with the City of Evanston but was abolished in 2014. County government is overseen by the Cook County Board of Commissioners, with its president as chief executive, and Cook County Treasurer. Countywide state government offices include the Circuit Court of Cook County, the Cook County State's Attorney, the Cook County Sheriff, and the Cook County Assessor.
Geographically, the county is the sixth-largest in Illinois by land area and the largest by total area. It shares the state's Lake Michigan shoreline with Lake County. Including its lake area, Cook County has a total area of 1,635 square miles (4,234.6 km2), the largest county in Illinois, of which 945 square miles (2,447.5 km2) is land and 690 square miles (1,787.1 km2) (42.16%) is water. Land-use in Cook County is mostly urban and densely populated. Within Cook County, the state of Illinois took advantage of its Lake Michigan access and the Chicago Portage, beginning with the construction of the Illinois and Michigan Canal in 1848. This helped make the region a central transit hub for the nation. Chicago, with its location on the Great Lakes and via the St. Lawrence Seaway, is a global port city, giving Cook County an international shipping port.
Cook County's population is larger than that of 28 U.S. states and territories, and larger than the population of 11 of the 13 Canadian provinces and territories.[6] Cook County is at the center of the Chicago metropolitan area, which has a population of approximately 10 million people.
History
[edit]Cook County was created on January 15, 1831, out of Putnam County by an act of the Illinois General Assembly. It was the 54th county established in Illinois and was named after Daniel Pope Cook, one of the earliest and youngest statesmen in Illinois history. He served as the second U.S. representative from Illinois and the state's first attorney general. In 1839, DuPage County was carved out of Cook County.

Cook County's current size was formed in 1839 by the creation of DuPage County
The shape of Cook County and the neighboring counties has remained the same since DuPage County was formed. The population in each county and the split of agriculture compared to residential and industrial activity has changed dramatically over the intervening decades to 2020. The county began with 10,201 people in the census of 1840, growing rapidly to 5,150,233 people estimated for 2019 by the US census. Growth was rapid in the 19th century, with the County reaching 2.4 million people by 1910. In the 20th century, the County reached 5.1 million population.
Cook County is nearly completely developed, with little agricultural land remaining near the outer county boundaries.[7]

[edit]Government and politics
[edit]Government
[edit]The government of Cook County is primarily composed of the Board of Commissioners headed by the President of the County Board, other elected officials such as the Sheriff, State's Attorney, Treasurer, Board of Review, Clerk, Assessor, Recorder, Circuit Court judges, and Circuit Court Clerk, as well as numerous other officers and entities. Cook County is the only home rule county in Illinois.[26] The Cook County Code is the codification of Cook County's local ordinances. Cook County's current County Board president is Toni Preckwinkle.
The Circuit Court of Cook County, which is an Illinois state court of general jurisdiction is funded, in part, by Cook County, and accepts more than 1.2 million cases each year for filing.[27] The Cook County Department of Corrections, also known as the Cook County Jail, is the largest single-site jail in the nation. The Cook County Juvenile Detention Center, under the authority of the Chief Judge of the court, is the first juvenile center in the nation and one of the largest in the nation. The Cook County Law Library is the second-largest county law library in the nation.
The Bureau of Health Services administers the county's public health services and is the third-largest public health system in the nation. Three hospitals are part of this system: John H. Stroger, Jr. Hospital of Cook County, Provident Hospital, and Oak Forest Hospital of Cook County, along with over 30 clinics.
The Cook County Department of Transportation is responsible for the design and maintenance of roadways in the county. These thoroughfares are composed mostly of major and minor arterials, with a few local roads. Although the County Department of Transportation was instrumental in designing many of the expressways in the county, today they are under the jurisdiction of the state.
The Cook County Forest Preserves, organized in 1915, is a separate, independent taxing body, but the Cook County Board of Commissioners also acts as its Board of Commissioners. The district is a belt of 69,000 acres (280 km2) of forest reservations surrounding the city of Chicago. The Brookfield Zoo (managed by the Chicago Zoological Society) and the Chicago Botanic Garden (managed by the Chicago Horticultural Society) are located in the forest preserves.
Cook County is the fifth-largest employer in Chicago.[28]
In March 2008, the County Board increased the sales tax by one percent to 1.75 percent. This followed a quarter-cent increase in mass transit taxes. In Chicago, the rate increased to 10.25 percent, the steepest nominal rate of any major metropolitan area in America. In Evanston, sales tax reached 10 percent and Oak Lawn residents pay 9.5 percent.[29] On July 22, 2008, the Cook County board voted against Cook County Commissioner's proposal to repeal the tax increase.[30]
In 2016, Cook County joined Chicago in adopting a $13 hourly minimum wage.[31] Cook County Board chairman John Daley called the wage hike "the moral and right thing to do." In June 2017, however, nearly 75 home rule municipalities passed measures opting themselves out of the increase.[32]
Politics
[edit]The county has more Democratic Party members than any other Illinois county and it is one of the most Democratic counties in the United States.[33] Since 1932, the majority of its voters have only supported a Republican candidate in a Presidential election three times, all during national Republican landslides–Dwight Eisenhower over native son Adlai Stevenson II in 1952 and 1956, and Richard Nixon over George McGovern in 1972. Since then, the closest a Republican has come to carrying the county was in 1984, when Ronald Reagan won 48.4 percent of the county's vote. In 2020, 74 percent of the county voted for Joe Biden and 24 percent voted for Donald Trump.
In 1936, with Franklin D. Roosevelt receiving 1,253,164 votes in the county, Cook County became the first county in American history where a candidate received one million votes.
The Cook County Democratic Party represents Democratic voters in 50 wards in the city of Chicago and 30 suburban townships of Cook County. The organization has dominated County, city, and state politics since the 1930s. The last Republican mayor of Chicago was William Hale "Big Bill" Thompson, who left office in 1931 with a record of corruption. The most successful Republican candidate for mayor since then was Bernard Epton, who in 1983 came within 3.3 percentage points of defeating Democrat Harold Washington.[34] The county's Republican Party organization is the Cook County Republican Party.
The last Republican governor to carry the county was Jim Edgar in his 1994 landslide. The last Republican senator to do so was Charles H. Percy in 1978.

Secession movements
[edit]To establish more localized government control and policies which reflect the often different values and needs of large suburban sections of the sprawling county, secession movements have been made over the years which called for certain townships or municipalities to form their own independent counties.
In the late 1970s, a movement started which proposed a separation of six northwest suburban townships, Cook County's panhandle (Barrington, Hanover, Palatine, Wheeling, Schaumburg, and Elk Grove) from Cook to form Lincoln County, in honor of the former U.S. president and Illinois resident.[37] It is likely that Arlington Heights would have been the county seat. This northwest suburban region of Cook was at the time moderately conservative and has a population over 500,000. Local legislators, led by State Senator Dave Regnar, went so far as to propose it as official legislation in the Illinois House. The legislation died, however, before coming to a vote.
In 2004, Blue Island mayor Donald E. Peloquin organized a coalition of fifty-five south and southwest suburban municipalities to form a new county, also proposing the name Lincoln County. The county would include everything south of Burbank, stretching as far west as Orland Park, as far east as Calumet City, and as far south as Matteson, covering an expansive area with a population of over one million residents. Peloquin argued that the south suburbs are often shunned by the city (although Chicago is not bound or required to do anything for other municipalities) and he blamed the Chicago-centric policies of Cook County for failing to jumpstart the somewhat-depressed south suburban local economy. Pending sufficient interest from local communities, Peloquin planned a petition drive to place a question regarding the secession on the general election ballot, but the idea was not met with success.[38]
In arguing against the Lincoln County proposal, others noted several of the cities involved had power structures, law enforcement, or de facto "mayors for life" often accused in the press, or civilly or criminally charged with, political corruption, cronyism, and nepotism, and themselves being the main factor in their depressed economies rather than anyone in Cook County government. The opposition decried that their true reason for joining the secession effort was to start with a 'clean slate' with a new county government by design less willing to enforce responsibility against their abuses of power.[39][40]
Talk of secession from Cook County amongst some outlying communities again heated up in mid-2008 in response to a highly controversial 1% sales tax hike which has pushed the tax rates across the county communities up amongst the highest in the nation. Some border towns in particular had been outraged, as people can take their business across the county border (paying, for instance, 7% in Lake County instead of Palatine's 9.5%).[41] The secession issue eventually died down from the nominal tax increase.
In 2011, two downstate Republican state representatives, Bill Mitchell of the 87th district and Adam Brown of the 101st district, proposed statehood for Cook County. Mitchell said that Chicago is "dictating its views" to the rest of the state and Brown added that Chicago "overshadows" the rest of Illinois.[42]
Infrastructure
[edit]Canals
[edit]Construction of the Erie Canal in New York State made a connection from the Atlantic Ocean to the Great Lakes in 1821. As the Midwest farms proved productive, with much grain to sell to other parts of the US, Chicago and Cook County saw the benefit of a canal to improve the link from the Great Lakes to the Mississippi River. The Illinois and Michigan Canal was completed in 1848, extending from the Bridgeport neighborhood in Chicago on the Chicago River, to the Illinois River at the cities of LaSalle-Peru. This canal spurred the growth of Chicago and the areas around it, as water travel was the primary way to ship grain or other commodities in that part of the 19th century. The Illinois and Michigan Canal ceased major operation in 1933. Portions are now designated as a National Historic Corridor. The two canals and the Great Lakes cemented trade ties between the Midwest and the Northeast, encouraging farmers to grow more than they needed to feed themselves in Illinois, with a large market for grain now open to them. Towns in Cook County along the Canal grew. From a national perspective, the trade ties made the South region of the US less important to the Northeast as a trade partner.
The Chicago Sanitary and Ship Canal, completed in 1900, largely replaced the functions of the Illinois and Michigan Canal. This canal resulted in the reversal of the direction of flow of the main stem and the South branch of the Chicago River; they used to empty into Lake Michigan and now those river sections flow toward the Des Plaines River. The Sanitary and Ship Canal was built to serve many aims, including ending using Lake Michigan as a sewer, sending waste water through treatment plants and sending it away from Lake Michigan. It is also a waterway for movement of ships.
Railway network
[edit]The next major technology for transportation was railroads. Chicago and the towns along the canal and rivers understood the value of being a hub of a major network. Rail lines spurred out from Chicago by the 1850s, with major growth in the rail network for freight and passenger transportation coming after the American Civil War, when the transcontinental railroads were completed, coast to coast across the US, stopping in Chicago, the heart of Cook County.
Local transit

Major highways
[edit]Following on the well-established position of Chicago as a transportation hub, the Interstate highway network maintained Chicago as a hub of that network, as well as serving the travel needs within the region.
Airports
[edit]When the age of air travel began in the 20th century, Midway Airport was built on 1 square mile (2.6 km2) of land and served as the major Chicago area airport from 1927 to 1955. Midway has been enlarged and continues to operate as of 2024[update]. As air travel became more important for passenger travel, and then for select freight commodities, O'Hare International Airport was built adjacent to a military airfield in the northwest part of Cook County. The City of Chicago annexed the land for the airport, so that the city controls both airports serving a large area. During the second half of the 20th century, it was the world's busiest airport. The approach of Cook County and Chicago to air travel has been the same as the approach to canal, railroad and highway transportation, to serve as a major national hub.
There has been a long running plan for a third major airport to serve the south side of the city and the southern and southwestern suburbs, the Proposed Chicago south suburban airport intended for Peotone, Illinois. The state of Illinois has been addressing this topic since 1986. Some land has been acquired, but there is not a functioning airport there, as of August 2020[update].
