Oak Park is a village in Cook County, Illinois, adjacent to Chicago. It is the 29th-most populous municipality in Illinois with a population of 54,583 as of the 2020 U.S. Census estimate. Oak Park was first settled in 1835 and later incorporated in 1902, when it separated from Cicero. Architect Frank Lloyd Wright and his wife settled in Oak Park in 1889, and his work heavily influenced local architecture and design. In 1968, Oak Park passed the Open Housing Ordinance, which helped devise strategies to integrate the village rather than resegregate. Today Oak Park remains ethnically diverse, and is known for its socially liberal politics, with 80% or higher voter turnout in every presidential election since 2000. The village is closely connected to Chicago with Chicago Transit Authority access via the Green Line and Blue Line "L" train lines, as well as the Metra Oak Park station downtown. In the future village of Oak Park, this system ran east-west on Madison Street and Lake Street, with a north-south connection on Harlem Avenue. Streetcar service was discontinued in 1947, although the Lake Street Elevated Railroad (todays CTA Green Line CTA Blue Line) was extended into the Oak Park level in 1899-1901. The "Met" line moved onto new tracks along the Congress Expressway in 1958 (Eisenhower) The village's population grew quickly and most of the current village's buildings were built in the 1950s and 1960s.


In 1835, Joseph and Betty Kettlestrings, immigrants from Yorkshire, England, staked out a farm and built a house near Lake Street and Harlem Avenue, west of Chicago. By 1850, the Galena and Chicago Union Railroad was constructed as far as Elgin, Illinois, and passed through the settlement area. In the 1850s the land on which Oak Park sits was part of the new Chicago suburb, the town of Cicero. The population of the area boomed during the 1870s, with Chicago residents resettling in Cicero following the Great Chicago Fire of 1871. As Chicago grew from a regional center to a national metropolis Oak Park expanded from 500 residents in 1872 to 1,812 in 1890, to 9,353 in 1900, to 20,911 in 1910, to 39,585 in 1920. The village population grew quickly, and "by 1930, the village had a population of 64,000, even larger than the current population", while cherishing a reputation as the "World's Largest Village" After World War II, Oak Park was affected by larger developmental trends in the Chicago Metropolitan area. Starting in the mid 1950s and 1960s, the Village of Oak Park has made a larger portion of the southern portion of Chicago in the Metropolitan area a part of its own. Oak Park is now home to the Chicago Cubs baseball team, the Chicago Bulls football team, and the Chicago Blackhawks hockey team. The Chicago Cubs won their first World Series championship in 1968.


The entire village of Oak Park lies on the shore of ancient Lake Chicago, which covered most of the city of Chicago during the last Ice Age. Ridgeland Avenue in eastern Oak Park marks the shoreline of the lake, and was once an actual ridge. One of North America's four continental divides runs through Oak Park. This divide, a slight rise running northsouth through the village, separates the Saint Lawrence River watershed from the Mississippi River watershed. According to the 2010 census, Oak Park has a total area of 4.7 sq mi (12.17 km²), all land. The village is located on the banks of the ancient Des Plaines river, which once emptied into glacial Lake Chicago. The ancient lake was the forerunner to today's Lake Michigan, which connects to the present day Lake Michigan just north of the Loop. Oak Park is home to the Chicago Cubs baseball team, the Chicago Bulls football team, and the Chicago Blackhawks hockey team. The Chicago Cubs won the World Series in 2008, 2009, 2010, and 2012. The Blackhawks won the Super Bowl in 2008 and 2010, as well as the 2010 Winter Olympics. The Bears won the Winter Olympics in 2010 and 2012, and won the gold medal in the 2010 men's ice hockey game against the Sweden team. The game was the first to be held in the United States since 1998. The Winter Olympics were held in Chicago from 2010 to 2014. The games were held on the ice in Chicago's Soldier Field, which was once the site of the Chicago River.


The Eisenhower Expressway is the primary expressway between Chicago and Oak Park. The streets are laid out in a grid pattern, occasionally with local streets ending in a cul-de-sac to maintain local character. Oak Park has its own street-numbering system that begins, for eastwest streets at Austin Boulevard (no east or west designation), and for northsouth streets, at the elevated train tracks located just south of Lake Street. The border streets do not follow the Oak Park numbering system; rather, they match the address system with the cities sharing those border streets. Augusta Boulevard through the village is part of the Grand Illinois Trail; the trailhead of the Illinois Prairie Path is less than a mile from the village. With several cycle clubs and groups, Oak Park is considered a bicycle-friendly community, and the tree-lined streets of the community, as well as its proximity to trails in nearby communities, attract cyclists to Oak Park, easily accessed by the Green Line, Blue Line, or Metra. The Village Board cancelled the Divvy bike sharing program in 2017, after the program was determined not to be cost-effective. The Green Line and the Blue Line are accessible from Chicago by service on the CTA's Green and Blue Lines. Bus transit service within Oak Park and to other suburbs is also provided by the CGA and Pace. The village has a station for Metra's Union Pacific / West Line. It is located near Chicago's O'Hare International Airport.


As of the 2010 census, 51,878 people, 22,670 households, and 13,037 families were residing in the village. In Oak Park, 13.1% spoke a language other than English at home and 10.3% were foreign-born. In the 1960s, Oak Parkers began a concerted effort to avoid the destructive racial housing practices occurring in nearby communities. In 1972, the Oak Park Housing Center was founded by Roberta "Bobbie" Raymond to promote integration in the community. Part of this effort included banning "for sale" signs on houses. Although this law became unconstitutional with the decision in Linmark Associates, Inc. v. Township of Willingboro, use of the signs is still strongly discouraged by local realtors. As late as 2000, there were no resegregated census tracts, with tracts ranging from 7% black to 36% black. This was not because the pattern of rapid westward resegregation had run its course, because events in neighboring suburbs showed that segregation trends were still operating. Instead, the pattern in a sense leaped over Oak Park to other suburbs farther west, including Bellwood and Maywood, which resegregate in a relatively short time. The median income for a family was $105,217. The per capita income for the village was $53,972. About 5.9% of families and 8.0% of the population were below the poverty line, including 9.0 per cent of those under age 18.


Since 1951, Oak Park has been organized under the council-manager form of municipal government. The village government includes an elected president and an elected village board, which hires a village manager to conduct the day-to-day affairs of the administration. Oak Park's election turnout varies greatly depending on whether it is a municipal or national election. The public primary schools (Lincoln, Mann, Longfellow, Beye, Irving, Holmes, Whittier, and Hatch) and the middle schools, Percy Julian Middle School (formerly Nathaniel Hawthorne) and Gwendolyn Brooks Middle School are operated by the Oak Park Elementary School District. These ten schools are part of elementary school District 97, which serves the entire city limits. The Park District of Oak Park was first organized in 1912 as the Recreation Department. In the late 1980s, the Park District was created as a separate tax-levying body. It comprises thirteen parks scattered throughout the village, for a total of 80 acres (320,000 m2) of parkland. The Oak Park Public Library has a main campus overlooking Scoville Park at the corner of Oak Avenue and Lake Street, and two branches, the Dille Park and Ridgeland branches. It was originally built in 1962 and renovated from March 2013 to June 14, 2014. The city's public high school is Oak Park and River Forest High School, the sole school in educational District 200, and Fenwick High School. Both high schools have a long history of high academic standards, and bestows the Tradition of Excellence Award to distinguished alumni.

Arts and culture

Oak Park is home to several professional dance and theatre companies, including Circle Theatre, Oak Park Festival Theatre, and The Academy of Movement and Music. The Oak Park Art League (OPAL), a nonprofit visual arts center founded after World War I (renamed in 1970), provides classes, workshops, lectures, demonstrations, and exhibitions. The July 4 celebration featuring fireworks draws thousands to the Oak Park-River Forest High School football stadium. A Day in Our Village, held in June, allows local groups to set up tables to seek members of the community. The band Born an Abomination, was an act in the depressive metal genre, originated from Oak Park. Their album Fires in the Night Hour... from the year 2016 includes a song titled 'Oak Park' in dedication to the band's home. The city is located on the Illinois River, which runs through the center of the city. It is located seven miles west of Chicago's downtown area, and is located in the heart of the Chicago metropolitan area. It has a population of around 2.5 million, making it one of the most ethnically diverse cities in the U.S., along with New York City, Los Angeles, and San Francisco. It also has a reputation for being a great place to live and work, as well as a good place to raise a family. It was the site of the World War II-era Battle of the Bulge, which took place in the early 1950s. It's also home to a number of cultural institutions, including the National Museum of American History, the Chicago History Museum, and the Chicago Museum of Art.

There are 2,400 historic sites in Oak Park, the majority of which are homes built in the Queen Anne, Prairie School and Craftsman styles of architecture. Three historic districts recognize the variety of styles often standing next door to each other. Frank Lloyd Wright spent the first 20 years of his 70-year career in the community, building numerous homes. Ernest Hemingway spent his first six years of life at 339 N. Oak Park Ave. The house was returned to its original 1890s' Victorian Heritage after restoration in 1992 and is open to the public for tours through The Ernest Hemedway Foundation of Oak Park. The Art Deco-style main post office on Lake Street was designed by White and Weber in 1933. It is part of the Ridgeland-Oak Park Historic District. A fourth district is under consideration as of 2015, of 176 homes built by Thomas Henry Hulbert. The village's historic preservation has been a priority since an ordinance passed in 1972 and since revised. The Village ofOak Park displays these online on an interactive website. There are three historic districts, outlined on a map from the village. The three districts areFrank Lloyd Wright, Ridgland-Oak park, and Seward Gunderson, outlined in the map below. The district name is based on the name of the village's first post office, which was established in 1858. The current district name comes from the name given to the village by the village in 1881. The historic district name was changed in 1883 to Oak Park-Ridgeland.
