Oak Brook is a village in DuPage and Cook Counties, in Illinois.[2] The population was 8,702 at the 2000 census. A suburb of Chicago, it is the headquarters of McDonald's and Lions Clubs International.



Oak Brook was incorporated as a Village in 1958, due in large part to the efforts of Paul Butler, a prominent civic leader and landowner whose father had first moved to the vicinity in 1898 and opened a dairy farm shortly thereafter. Prior to incorporation, the name Oak Brook was used by local residents to distinguish their community from neighboring Hinsdale and Elmhurst, going back to the founding of the Oak Brook Civic Association almost two decades earlier.[3]

The original boundaries were smaller than the present extent of the Village, but a considerable amount of land was acquired soon after the founding of the Village, including the land that is now the site of the Oakbrook Center shopping mall, which opened in 1962.

Paul Butler's interest in sport was reflected in the Oak Brook Sports Core, which features polo fields, a golf course (which was at one time the venue for the Western Open), swimming and tennis facilities, and other recreational facilities not commonly found in a village of this size.[4]

In October 2009, the employees of the Oak Brook Public Library invited the Teamsters to represent them.[5]


Oak Brook is located at 41°50′24″N 87°57′11″W / 41.84°N 87.95306°W / 41.84; -87.95306Coordinates: 41°50′24″N 87°57′11″W / 41.84°N 87.95306°W / 41.84; -87.95306 (41.84018, −87.953079)[6].

According to the United States Census Bureau, the village has a total area of 8.3 square miles (21 km2), of which, 8.2 square miles (21 km2) of it is land and 0.1 square miles (0.26 km2) of it (1.21%) is water.

The village's proximity to the junction of Interstates 88, 294, and 290, about 20 miles (32 km) west of downtown Chicago, makes access by car easy for residents of Chicago and other suburbs. Although Oak Brook is not directly served by any CTA or Metra trains, the commercial corridor along 22nd Street is served by several PACE bus routes, and train stations in neighboring villages offer commuter train access to downtown Chicago.

Most of Oak Brook consists of residential subdivisions, with the exception of the Oakbrook Center shopping mall and other retail and office properties along 22nd Street and the Interstate 88 corridor in the northern part of the village.


As of the census[7] of 2000, there were 8,702 people, 3,124 households, and 2,589 families residing in the village. The population density was 1,066.4 people per square mile (411.7/km²).

The racial makeup in the 2010 census was 71.80% White, 2.00% African American, 23.20% Asian, 0.00% Pacific Islander, 0.70% from other races, and 1.69% from two or more races. Hispanic or Latino of any race were 4.30% of the population.

The average household size was 2.74 and the average family size was 3.04.

In the village the population was spread out with 19.6% under the age of 18, 6.9% from 18 to 24, 15.3% from 25 to 44, 36.4% from 45 to 64, and 21.8% who were 65 years of age or older. The median age was 50 years. For every 100 females there were 91.1 males. For every 100 females age 18 and over, there were 89.5 males.
