Oak Park is a village in Cook County, Illinois, adjacent to Chicago. It is the 26th-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. It is closely tied to the smaller town of River Forest, sharing Oak Park and River Forest High School. Architect Frank Lloyd Wright and his wife settled in Oak Park in 1889, and his work heavily influenced local architecture and design, including the Frank Lloyd Wright Home and Studio. Over the years, rapid development was spurred by railroads and streetcars connecting the village to jobs in nearby Chicago. In 1968, Oak Park passed the Open Housing Ordinance, which helped devise strategies to integrate the village rather than resegregate.
