Fox River Grove, IL population, income and ZIP codes

Fox River Grove village is a small town in Illinois, with 4,501 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #351 of 1,462 ranked by population — larger than 76% of them. The median age here is 39 years against 39.1 nationally, a slightly younger profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Fox River Grove village earn a median of $125,104 a year, 59.3% above the national figure of $78,538 and 69% above the $74,244 median for the 698 Illinois cities we cover. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 2.9% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Fox River Grove village is valued at $289,200, 4.7% below the national figure and 61% above the $179,100 peer median, while median gross rent runs $2,157 a month, 53.4% above the national figure, or roughly $25,884 across a full year. A household on the local median income would put about 20.7% 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 2.3×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 85.7% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

Every value on this page is published directly by the Census for this area — nothing is modelled or interpolated. 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.
