East Alton, IL population, income and ZIP codes

East Alton village is a mid-size town in Illinois, with 5,729 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #315 of 1,462 ranked by population — larger than 78% of them. The median age here is 45.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. 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 East Alton village earn a median of $46,926 a year, 40.3% below the national figure of $78,538 and 37% below 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 14.5% of residents here, above the 12.4% national rate.

The typical owner-occupied home in East Alton village is valued at $99,600, 67.2% below the national figure and 44% below the $179,100 peer median, while median gross rent runs $819 a month, 41.7% below the national figure, or roughly $9,828 across a full year. A household on the local median income would put about 20.9% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 2.1×, 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. 62.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans more heavily on renters. 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.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.
