Warrenville city, IL in context

How this area compares with national benchmarks.

Warrenville city is a mid-size town in Illinois, with 14,232 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #172 of 1,462 ranked by population — larger than 88% of them. The median age here is 37.2 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in Warrenville city earn a median of $99,028 a year, 26.1% above the national figure of $78,538 and 33% above the $74,244 median for the 698 Illinois cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 11% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Warrenville city is valued at $266,500, 12.2% below the national figure and 49% above the $179,100 peer median, while median gross rent runs $1,759 a month, 25.1% above the national figure, or roughly $21,108 across a full year. A household on the local median income would put about 21.3% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.7×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 75.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Rent is reported gross — contract rent plus tenant-paid utilities — which is why it runs above the advertised price on a listing for the same unit.
