Sterling city, IL in context

How this area compares with national benchmarks.

Sterling city is a mid-size town in Illinois, with 14,670 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #168 of 1,462 ranked by population — larger than 88% of them. The median age here is 42.6 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 Sterling city earn a median of $52,647 a year, 33% below the national figure of $78,538 and 29% below the $74,244 median for the 698 Illinois cities we cover. Median household income counts every pre-tax dollar arriving at an address — wages, self-employment, Social Security, pensions, interest and public assistance — for everyone living there, so multi-earner households pull the figure up even where individual pay is modest. Poverty reaches 16.4% of residents here, above the 12.4% national rate.

The typical owner-occupied home in Sterling city is valued at $107,800, 64.5% below the national figure and 40% below the $179,100 peer median, while median gross rent runs $780 a month, 44.5% below the national figure, or roughly $9,360 across a full year. A household on the local median income would put about 17.8% 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. 61.8% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
