How big a city is Cincinnati? It is a question that often comes up when people compare U.S. cities and regions.
How big a city Cincinnati is can mean different things: population, land area, density, and regional influence.
Cincinnati ranks as one of Ohio’s largest cities. According to Ohio Demographics, Cincinnati’s population reached about 314,915 in 2025, making it the third‑most populous city in the state behind Columbus and Cleveland.
Cincinnati covers a substantial urban footprint for its size. According to Encyclopædia Britannica, the city spans approximately 80 square miles (206 square kilometers) of land area, establishing a dense, tightly built city core within Hamilton County.

How big a city is Cincinnati by population
Cincinnati’s city population has fluctuated over time. According to the 2020 U.S. census, the city had 309,317 residents—the largest total since mid‑20th century declines reversed.
Recent estimates place Cincinnati’s population around 310,000–315,000 people as of 2024‑2025. This positions Cincinnati among the top three largest cities in Ohio.
Population density data further illustrate Cincinnati’s urban character. According to historical census information, Cincinnati had a density of about 3,810 people per square mile in 2010.
Other demographic sources show a similar figure of 3,885 residents per square mile, well above the national average.
Population demographics also reflect Cincinnati’s diversity and younger median age. According to Data USA, the city’s median age was about 33 in 2023, with steady population growth year‑over‑year.
These figures show how big a city Cincinnati is beyond raw population totals: the urban core supports a dense, active residential base with ongoing growth trends.
How big a city is Cincinnati in the context of Ohio and the metro region
Cincinnati’s city limits are smaller than some other major U.S. cities, but its regional influence extends far beyond. Within Ohio, it ranks third in population—behind Columbus (~933,000) and Cleveland (~365,000).
The Greater Cincinnati metropolitan area adds substantial scale. According to the U.S. Census Bureau, the Cincinnati–OH‑KY‑IN metropolitan statistical area had about 2.256 million people as of the 2020 census.
That metro region, commonly called the Tri‑State area, spans counties across Ohio, Kentucky, and Indiana, and serves as a major economic hub in the Midwest.
In practical terms, this means Cincinnati’s influence is far greater than what the city limits alone show, impacting nearly 2.3 million residents of the broader region.
For context:
- City of Cincinnati population: ~315,000 (2025 est.)
- City land area: ~80 square miles
- Metro area population: ~2.26 million
These figures make Cincinnati one of the largest metro areas in the Midwest, comparable to other major urban regions in states like Michigan, Indiana, and Wisconsin.
Density and urban scale: How big a city is Cincinnati in the built environment
Population numbers only tell part of the story of how big a city Cincinnati is. Another way to look at size is by density and built environment.
With the recent population rebound to roughly 315,000 residents within nearly 78 square miles, Cincinnati’s population density is approximately 4,000 inhabitants per square mile.
This places the city above many geographically larger U.S. cities (such as Nashville or Indianapolis) in terms of how closely people live within the urban footprint.
Urban density influences daily life — from commuting patterns to housing availability. Higher density often correlates with:
- more transit options
- closer amenities
- vibrant neighborhood centers
Cincinnati’s density reflects a compact urban core with strong residential and commercial districts, distinguishing it from more sprawling midwestern peers.
