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. According to 2008
US Census Bureau estimates, the county has
5,294,664 residents, which is larger than the populations of 29
individual
U.S.
states, the combined populations of the six smallest US states,
and home to 43.3% of Illinois residents.
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 thirty different townships.
Geographically the
county is the fifth largest in Illinois by land area and shares the
state's coast line on Lake Michigan
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 Circuit Court of Cook County, which files more than 1.2 million
cases every year, the Cook County Department of Corrections, which
is 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
hospitals.
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.
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 of any major metropolitan
area in America. In Evanston
, sales tax reached 10 percent and Oak Lawn residents will pay 9.5 percent. On
July 22, 2008, the Cook County board voted against Cook County
Commissioner's proposal to repeal the tax increase.

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. 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 cited 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.
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 tax rates across the various other county
communities up amongst the highest in the nation. Border towns in
particular have been outraged, as without a captive tax base like
Chicago, people can easily 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.

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

is named "Cook County General Hospital", although filmed in Los

Blues Brothers, the title characters race to the offices
of the Cook County Assessor to pay the back taxes owed by the

reality, however, back taxes are paid in the Office of the Cook
County Treasurer, and church-owned property is tax exempt anyway.
Near the
end, a car is driven through the lobby of the Daley
Center courthouse
, and the County Building is stormed by the title
characters and hundreds of policemen and soldiers. Murphy Dunne, who played the pianist in the
movie, is the son of then Cook County Board President George Dunne.
