Sleepy Hollow, IL population, income and ZIP codes

Sleepy Hollow village is a small town in Illinois, with 3,165 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #418 of 1,462 ranked by population — larger than 71% of them. The median age here is 48.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 Sleepy Hollow village earn a median of $147,407 a year, 87.7% above the national figure of $78,538 and 99% above 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 5% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Sleepy Hollow village is valued at $365,200, 20.4% above the national figure and 104% above the $179,100 peer median, while median gross rent runs $1,206 a month, 14.2% below the national figure, or roughly $14,472 across a full year. A household on the local median income would put about 9.8% 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 2.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 93.6% 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.
