DuPage County at the time of its creation in 1839

DuPage County is a county in the U.S. state of Illinois, and one of the collar counties of the Chicago metropolitan area. As of the 2010 census, the population was 916,924,[2] making it Illinois' second-most populous county. Its county seat is Wheaton.[3]

With a population nearing one million, DuPage County has become mostly developed and suburbanized, although some small pockets of farmland remain in the county's western part. The county has a vast socioeconomic profile; residents of Hinsdale, Naperville, and Oak Brook include some of the wealthiest people in the Midwest. In 2010, Midwest Living voted Hinsdale the Midwest's second wealthiest town, the first being Fairway, Kansas. In stark contrast, the large unincorporated area of Downers Grove Township is very blue collar, with many residents below the poverty line.[4]


DuPage County was formed on 9 February 1839 out of Cook County.[5] The county took its name from the DuPage River, which was, in turn, named after a French fur trapper, DuPage.[6] The first written history to address the name, the 1882 History of DuPage County, Illinois, by Rufus Blanchard, relates:[7]


According to the U.S. Census Bureau, the county has a total area of 336 square miles (870 km2), of which 327 square miles (850 km2) is land and 8.9 square miles (23 km2) (2.6%) is water.[8] The DuPage River and the Salt Creek flow through DuPage County. According to the Forest Preserve District of DuPage County, the highest point in the county is located at the Mallard Lake Landfill, which at its highest point is 982 feet (299 m) above mean sea level.[9]

Historically, DuPage County was a stronghold of the Republican Party, and was reckoned as a classic bastion of suburban conservatism, but like many suburban counties has trended Democratic in presidential years.

National Politics[edit]

The county supported Democrat Barack Obama, a Chicago resident, in 2008 and 2012 (albeit narrowly in 2012). Obama was the first Democratic presidential nominee to win the county since Franklin Pierce in 1852; hence, the last time before Obama that any Republican failed to win the county was before the Republican Party existed.

In the U.S. House of Representatives, DuPage County is in the 5th, 6th, 8th, 11th and 14th districts.

Local politics[edit]

Republicans have controlled local politics in DuPage County since the nineteenth century. Democrats have only held countywide office twice. In 1934 William Robinson was elected Circuit Clerk and Arthur Hellyer was elected Treasurer. That year also saw the only Democratic majority county board in DuPage history.[34][35] Robinson and Hellyer each served one term; Robinson lost his bid for a full term in 1936 and Hellyer left the Treasurer’s office to make a failed bid for probate judge in 1938.[36]

Democrats were sporadically elected at the county and township levels. In 1972, Don Carroll was elected to the County Board. In the Democratic wave of 1974, Jane Spirgel, Mary Eleanor Wall, and Elaine Libovicz were elected. All four were from the northeastern portion of DuPage, which at that time was the most Democratic.[37] Republicans regained all seats on the board when Jane Spirgel ran for Illinois Secretary of State with Adlai Stevenson III under the Solidarity Party banner.[38] In 2000, Linda J. Bourke Hilbert was elected. Like her 1970s counterparts, she was from the northeastern portion of the county.[39] During the 2008 Democratic wave, three Democrats were elected to the board.[40] As of 2016, Democrats hold only one of eighteen board seats.

In 1973, a slate of Democrats took eight of nine offices in Addison Township. This feat would not be replicated until 2015 when Democratic candidates won a majority of offices in Naperville and Lisle townships.[41] Between these two victories, Democrats only held two township offices. Mark Starkovich served as York Township Supervisor from 1989-1993 and Martin McManamon has served as Wayne Township Highway Commissioner since 2013.[42][43]


Colleges and universities[edit]

The College of DuPage, in Glen Ellyn, is one of the largest community colleges in the United States. Wheaton College is one of the most well-known and respected evangelical Christian colleges in the country. Benedictine University, Elmhurst College and North Central College also have long and respected histories in their communities.

Other prominent colleges and universities include: Midwestern University in Downers Grove; National University of Health Sciences and Northern Baptist Theological Seminary in Lombard; the Addison, Naperville and Oak Brook campuses of DeVry University; the Aurora campus of Robert Morris University; the Lisle campus of National–Louis University; the Naperville campuses of DePaul University and Northern Illinois University; the Wheaton campus of Illinois Institute of Technology; and the DuPage campus of Westwood College in Woodridge. Hamburger University, McDonald's global training facility, is located at its corporate headquarters in Oak Brook, on an 80-acre (32 ha) campus.
