Saline ZIP codes — Saline County, Illinois

Saline County is a mid-size town in Illinois, with 23,387 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates. The median age here is 43.2 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 Saline County earn a median of $54,945 a year, 30% below the national figure of $78,538. 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 17.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Saline County is valued at $92,900, 69.4% below the national figure, while median gross rent runs $711 a month, 49.4% below the national figure, or roughly $8,532 across a full year. A household on the local median income would put about 15.5% 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 1.7×, 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. 74.9% 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.

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.
