Overview
Understanding ZIP code 45204
ZIP code 45204 is assigned to Cincinnati, OH, and falls within Hamilton County. Like every US postal code, it began as a mail-routing device rather than a geographic boundary — the US Postal Service groups delivery routes under a single code so carriers and sorting equipment can process mail efficiently. Today it also serves as a practical shorthand for the area itself: roughly 7,710 people live inside it.
At 2,507 residents per square mile spread over 3.075 square miles, 45204 reads as a suburban area. It is a smaller postal code by population, and density shapes almost everything else on this page — how people get to work, whether they own or rent, and what housing costs.
Household earnings are well below the national median. At $30,579, 45204 ranks among the lower-income postal codes, ahead of 2% of them. The US median for comparison is $70,109. Bear in mind that median income describes the midpoint household, not the average — it is not pulled upward by a handful of very high earners the way a mean would be.
Living here
What life in Cincinnati looks like
Housing in 45204 costs well below the national median. A typical home is valued at $93,100 against a US median of $207,500, and median gross rent runs $771 a month. The split between owning and renting is fairly even at 42.1% owner-occupied, which tends to indicate a mix of housing types rather than one dominant form.
The building stock is dominated by detached single-family houses, which account for 40.7% of housing units here. The median construction year is 1952, making the housing here mid-century. The vacancy rate of 20.7% is high, which in many places reflects seasonal or second-home use rather than abandonment.
The population skews younger than the country as a whole, with a median age of 30.2 against 42 nationally. The average household holds 2.62 people, and 50.5% are family households.
Getting to work takes 25.3 minutes on average one way. The dominant mode is drove alone at 69.0% of workers, while 11.2% take public transit. Commute patterns are one of the better proxies for how a place actually functions day to day.
Where to stay
Where to stay in Cincinnati, OH
Cincinnati is largely suburban in character. Accommodation here skews toward mid-range chain hotels and extended-stay properties positioned near highway junctions and business parks, which suits anyone driving in or visiting for work rather than sightseeing.
Local costs are modest — median rent here is $771 a month — and accommodation prices in the area tend to be correspondingly reasonable. For reference, Chicago, IL is about 250.6 miles away in a straight line, which is worth factoring in if you are comparing a stay here against one closer to the city centre.

Practical uses
What ZIP code 45204 is used for
Beyond addressing mail, 45204 does a lot of quiet administrative work. Retailers use it to calculate shipping and sales tax at checkout. Insurers use it to set premiums, since risk profiles vary geographically. Employers and marketers use it to define service areas. Government agencies use it to route benefits and organise reporting. If you have ever been asked for a postal code by a form that clearly does not intend to send you anything, this is why.
For anyone weighing a move, 45204 offers a compact profile of Cincinnati: 7,710 residents, a median household income of $30,579, 21.0% of adults holding a bachelor's degree or higher, and an unemployment rate of 7.9%. A handful of figures like these answer more relocation questions than most neighbourhood guides do.
One caution worth repeating: a postal code is not a neighbourhood. 45204 may cover parts of several distinct areas, and a single neighbourhood in Cincinnati may be split across more than one code. Boundaries also shift as USPS adjusts delivery routes. Treat the figures here as describing a delivery area, which is what they actually measure.
