Dupage County, IL Property Records & Statistics
DuPage County is one of the more expensive housing markets in Illinois. The median rent is $1,580, roughly double the state median of $762 and the national figure of $840.25. Renter-occupied housing accounts for 22.69% of occupied homes, above the state's 18.61% and slightly above the national 21.81%, so renting is more common here than in the typical Illinois county.
The median home value is $375,200, far above the state median of $116,950 and the national median of $173,750. Property taxes add to the cost of ownership: the county's median property tax rate of 2.07% is higher than the state rate of 1.8% and nearly triple the national rate of 0.74%, which on homes of this value means substantial annual tax bills.
Incomes help absorb those costs. The median household income of $108,175 is well above both the Illinois figure of $65,699.50 and the national figure of $65,108. The unemployment rate of 2.96% is close to the state's 2.92% and the national 2.87%, showing a labor market in line with broader averages.
Overall, the figures describe a high-value, high-income county where housing and property taxes cost more than elsewhere, matched by earnings that are well above state and national levels.
