Fox Lake, IL population, income and ZIP codes

Fox Lake village is a mid-size town in Illinois, with 10,872 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #213 of 1,462 ranked by population — larger than 85% of them. The median age here is 43.3 years against 39.1 nationally, a slightly older 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 Fox Lake village earn a median of $69,896 a year, 11% below the national figure of $78,538 and 6% below 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 12.6% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Fox Lake village is valued at $219,300, 27.7% below the national figure and 22% above the $179,100 peer median, while median gross rent runs $1,059 a month, 24.7% below the national figure, or roughly $12,708 across a full year. A household on the local median income would put about 18.2% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is cheap relative to what people here earn. The home-price-to-income ratio works out to 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 66.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.
