Delaware city, OH in context

How this area compares with national benchmarks.

Delaware city is a small city in Ohio, with 43,168 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #28 of 1,265 ranked by population — larger than 97% of them. The median age here is 36.3 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 Delaware city earn a median of $92,928 a year, 18.3% above the national figure of $78,538 and 40% above the $66,250 median for the 689 Ohio cities we cover. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 8.7% of residents here, below the 12.4% national rate.

The typical owner-occupied home in Delaware city is valued at $279,400, 7.9% below the national figure and 66% above the $168,500 peer median, while median gross rent runs $1,203 a month, 14.4% below the national figure, or roughly $14,436 across a full year. A household on the local median income would put about 15.5% 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×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 62% 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.
