Wilmington, OH population, income and ZIP codes

Wilmington city is a mid-size town in Ohio, with 12,637 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #152 of 1,265 ranked by population — larger than 88% of them. The median age here is 36.7 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 Wilmington city earn a median of $52,661 a year, 32.9% below the national figure of $78,538 and 21% below the $66,250 median for the 689 Ohio 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 21.2% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in Wilmington city is valued at $162,700, 46.4% below the national figure and 3% below the $168,500 peer median, while median gross rent runs $925 a month, 34.2% below the national figure, or roughly $11,100 across a full year. A household on the local median income would put about 21.1% 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 3.1×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 56.7% 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.

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.
