Spring Valley, IL population, income and ZIP codes

Spring Valley city is a mid-size town in Illinois, with 5,508 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #320 of 1,462 ranked by population — larger than 78% of them. The median age here is 42.5 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 Spring Valley city earn a median of $63,964 a year, 18.6% below the national figure of $78,538 and 14% below the $74,244 median for the 698 Illinois cities we cover. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 10.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Spring Valley city is valued at $125,000, 58.8% below the national figure and 30% below the $179,100 peer median, while median gross rent runs $1,022 a month, 27.3% below the national figure, or roughly $12,264 across a full year. A household on the local median income would put about 19.2% 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 2×, 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. 63% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

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.
