Cook County is a county in the U.S. state of Illinois. It is the second most populous county in the United States after Los Angeles County. The county has 5,294,664 residents,[1] which is 43.3% of all Illinois residents. Cook County's population is larger than that of 29 individual U.S. states and the combined populations of the seven smallest US states.[2] There are over 130 incorporated municipalities in Cook County, the largest of which is the county seat, Chicago, which makes up approximately 54% of the population of the county. The county is divided into 30 different townships. Geographically the county is the fifth largest in Illinois by land area and shares the state's Lake Michigan shoreline with Lake County.

History

Cook County was created on January 15, 1831 out of Putnam County by an act of the Illinois State Legislature. It was the 54th county established in Illinois and was named after Daniel Cook, one of the earliest and youngest statesmen in Illinois history, who served as the second U.S. Representative from Illinois and the first Attorney General of the State of Illinois. Shortly thereafter, in 1839, DuPage County was carved out of Cook County.

Government and politics

Cook County's current County Board president is Todd Stroger. The county has by far more Democratic Party members than any other Illinois county, and is one of the most Democratic counties in the United States. It has voted only once for a Republican candidate in a Presidential election in the last forty years, when county voters preferred Richard Nixon to George McGovern in 1972.

The Cook County Democratic Organization is one of the most powerful political machines in American history. Commonly called the "Chicago Democratic machine", or simply the "Chicago Machine", the organization has dominated Chicago politics since the 1930s. Corruption and scandal have frequently been synonymous with the machine.

The Circuit Court of Cook County, which files more than 1.2 million cases every year,[3] the Cook County Department of Corrections, also known as the Cook County Jail, the largest single-site jail in the nation, and the Cook County Juvenile Detention Center, the first juvenile center in the nation and one of the largest in the nation, are solely the responsibility of Cook County government. 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 second 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 Highway Department is responsible for the design and maintenance of roadways in the county. These thoroughfares are mostly composed of major and minor arterials, with a few local roads. Although the Highway Department was instrumental in designing many of the expressways in the county, today they are under the jurisdiction of the state.

The Forest Preserve District, organized in 1915, is a separate, independent taxing body, but the Cook County Board of Commissioners also acts as the Forest Preserve District Board of Commissioners. The District is a belt of 69,000 acres (275 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.

In the 1980s, Cook County was ground zero to an extensive FBI investigation named Operation Greylord. Ninety-two officials were indicted, including 17 judges, 48 lawyers, 8 policemen, 10 deputy sheriffs, 8 court officials, and 1 state legislator. Cook County is the fifth largest employer in Chicago.[4]

In March 2008, the Cook County Board increased sales tax one percent, increasing the county sales tax rate from 0.75% to 1.75%. This followed a recent quarter-cent increase in mass transit taxing coming into effect in April. In Chicago, the rate increased to 10.25 percent, the steepest nominal rate of any major metropolitan area in America (the actual rate is much lower, as the sales tax does not apply to many items taxed elsewhere).[5] In Evanston, sales tax reached 10 percent and Oak Lawn residents will pay 9.5 percent.[6] On July 22, 2008, the Cook County board voted against Cook County Commissioner's proposal to repeal the tax increase.[7]

Secession movements

To establish more localized government control and policies which reflect the often different values and needs of large suburban sections of the sprawling county, several 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.[8] It is likely that Arlington Heights would have been the county seat. This northwest suburban region of Cook is 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 Peloquin tried to organize 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 and blamed the Chicago-centric policies of Cook County government for failing to jumpstart the long-depressed local economy of the south suburban region. Pending sufficient interest from local communities, Peloquin planned a petition drive to place a question regarding the secession on the general election ballot.[9]

Talk of secession amongst outlying communities have again heated up in mid-2008 in response to a highly controversial 1% sales tax hike which has pushed the sales tax rate in Chicago proper to 10.25%, and pushed the nominal tax rates across the various other county communities up amongst the highest in the nation (the actual rate is much lower, as the sales tax does not apply to many items covered by sales taxes in other major metropolitan areas, e.g., periodicals).[10][11] Border towns in particular have been outraged, as people can take their business across the county border (paying, for instance, 7% in Lake County instead of Palatine's 11%). In March 2009, advisory referenda in Barrington, Hanover and Palatine Townships passed recommending secession from Cook County.

Geography

According to the U.S. Census Bureau, the county has a total area of 1,635 square miles (4,235 km²), of which 946 square miles (2,449 km²) is land and 689 square miles (1,785 km²) (42.16%) is water, most of it in Lake Michigan. The highest point in Cook County is its northwest corner, at nearly 1,000 feet above sea level.[12]

Its eight former townships and annexed parts of others no longer have any governmental structure or responsibility since their annexations, but their names and boundaries are still used on property plats and by Cook County for tax assessment purposes.
