Forsyth, IL population, income and ZIP codes

Forsyth village is a small town in Illinois, with 3,656 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #399 of 1,462 ranked by population — larger than 72% of them. The median age here is 41.9 years against 39.1 nationally, a slightly older profile than the country as a whole. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in Forsyth village earn a median of $113,456 a year, 44.5% above the national figure of $78,538 and 53% above 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 10.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Forsyth village is valued at $289,800, 4.5% below the national figure and 62% above the $179,100 peer median, while median gross rent runs $1,207 a month, 14.2% below the national figure, or roughly $14,484 across a full year. A household on the local median income would put about 12.8% 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 2.6×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 92.3% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. 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.
