Aurora is a city in northeastern Illinois along the Fox River with a 2020 population of 180,542, making it Illinois's second-largest city after Chicago and the 144th-most populous in the United States. Founded in 1837 and officially incorporated in 1857 from the merger of East Aurora (incorporated 1845) and West Aurora (organized 1854), the city earned its "City of Lights" nickname in 1908 for being one of the first U.S. cities to implement all-electric street lighting in 1881. Originally a manufacturing hub centered on the Chicago, Burlington and Quincy Railroad's roundhouse and locomotive shop - the city's largest employer until the 1960s - Aurora has evolved into a major Chicago metropolitan area city with notable architecture by Frank Lloyd Wright, Mies van der Rohe, and others, plus over 50 Sears Catalog Homes and the 53,000-square-foot Hollywood Casino Aurora on Stolp Island. The city's economy and culture were shaped by waves of European immigration, particularly Luxembourgish settlers between 1850 and 1870, and it expanded from Kane County into DuPage, Kendall, and Will counties to become Illinois's most populous non-county-seat city. Naperville is a city in DuPage and Will counties in Illinois, located 28 miles west of Chicago on the DuPage River, with a 2020 census population of 149,540, making it the state's fourth-most populous city. Founded in 1831 by Joseph Naper as Naper's Settlement, the city grew to over 100 residents by 1832 and served as DuPage County's seat from 1839 to 1868 before experiencing significant population growth due to Chicago's urban sprawl beginning in the 1960s. Naperville is home to Moser Tower and Millennium Carillon, one of the world's four largest carillons, as well as an extensive parks and forest preserve network including Centennial Beach. Edward Hospital is the city's largest employer with 4,500 employees, and Naperville is served by Amtrak and Metra train stations. The city operates two school districts (203 and 204) and is known for its residential appeal as a Chicago suburb. Downers Grove is a village in DuPage County, Illinois, founded in 1832 by Pierce Downer, a farmer from Vermont, and named after the grove of old-growth bur oak trees that surrounded it. Located as a southwestern Chicago suburb between I-88 and I-55, the village had a population of 50,248 according to the 2020 census and covers 14.457 square miles. The Chicago, Burlington and Quincy Railroad's 1864 extension through Downers Grove spurred growth, and the village was officially incorporated in March 1873 with its distinctive apostrophe-free spelling. Today, Downers Grove is a bustling suburb home to major corporate headquarters including FTD, Dover, and HAVI Global Solutions, with historic significance as a stop on the Underground Railroad through its abolitionist-founded Lyman and Blodgett homes. The village has earned Tree City USA designation 28 times and features two forest preserves, though it has experienced controversy over high teardown rates and resulting flooding issues.
