Silvis, IL population, income and ZIP codes

Silvis city is a mid-size town in Illinois, with 7,939 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #265 of 1,462 ranked by population — larger than 81% of them. The median age here is 47.4 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Silvis city earn a median of $67,569 a year, 14% below the national figure of $78,538 and 9% 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 16.2% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Silvis city is valued at $161,300, 46.8% below the national figure and 10% below the $179,100 peer median, while median gross rent runs $975 a month, 30.7% below the national figure, or roughly $11,700 across a full year. A household on the local median income would put about 17.3% 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 2.4×, 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. 54.2% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

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.
