Cincinnati, OH population, income and ZIP codes

Cincinnati city is a mid-size city in Ohio, with 309,595 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #3 of 1,265 ranked by population — larger than 99% of them. The median age here is 33 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. At this size the Census also publishes one-year estimates; the five-year values used here are steadier and let you compare against smaller neighbours on the same basis.

Households in Cincinnati city earn a median of $51,707 a year, 34.2% below the national figure of $78,538 and 22% 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 24.5% 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 Cincinnati city is valued at $215,300, 29% below the national figure and 28% above the $168,500 peer median, while median gross rent runs $953 a month, 32.2% below the national figure, or roughly $11,436 across a full year. A household on the local median income would put about 22.1% 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 4.2×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 38.9% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

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.
