Sycamore city, IL in context

How this area compares with national benchmarks.

Sycamore city is a mid-size town in Illinois, with 18,243 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #138 of 1,462 ranked by population — larger than 90% of them. The median age here is 37.6 years against 39.1 nationally, a slightly younger 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 Sycamore city earn a median of $80,837 a year, 2.9% above the national figure of $78,538 and 9% 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 9.5% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Sycamore city is valued at $254,200, 16.2% below the national figure and 42% above the $179,100 peer median, while median gross rent runs $1,062 a month, 24.5% below the national figure, or roughly $12,744 across a full year. A household on the local median income would put about 15.8% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 71% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.
