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 51,878 as of the 2010 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, including the Frank Lloyd Wright Home and Studio. Over the years, rapid development was spurred by railroads and street cars 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.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. Oak Park is closely connected to Chicago with Chicago Transit Authority access via the Green Line and Blue Line "L" train lines including the Metra Oak Park station downtown.

Rosemont is a village in Cook County, Illinois, United States. Located immediately northwest of Chicago, as of the 2010 census it had a population of 4,202. The village was incorporated in 1956, though it had been settled long before that. While Rosemont's land area and population are relatively small among municipalities in the Chicago Metropolitan Area, the village is a major center for commercial activity in the region and is a key component of the Golden Corridor. Due to its proximity to several interstates, O'Hare International Airport, and downtown Chicago, it has emerged as a significant edge city and entertainment district, with corporate facilities, millions of square feet of office space, nearly 50 restaurants, 15 hotels, the 840,000-square-foot (78,000 m2) Donald E. Stephens Convention Center (home to conventions and trade shows), the 16,000+ seat Allstate Arena (home to the Chicago Wolves, Chicago Sky, DePaul Blue Demons until 2017, and concerts and other live entertainment events), the 4,000+ seat Rosemont Theatre, the 130-store Fashion Outlets of Chicago, the Rosemont Stadium (home to an outdoor collegiate-level softball stadium and 140,000 sq ft indoor sports dome), Impact Field (home to the Chicago Dogs independent minor league baseball team), and the entertainment complex Parkway Bank Park, which features restaurants, entertainment and a large common area used for summer concerts and ice skating in the winter. Rosemont is near Rivers Casino in Des Plaines and additional hotels, offices, restaurants, and corporate facilities in the adjacent O'Hare neighborhood of Chicago and nearby suburban communities such as Des Plaines and Schiller Park. The residential sections of Rosemont are a gated community, as a result of the 1995 decision by residents to enclose the residential portions of the village (roughly half the area of the village), thereby restricting access to locals.
