Overview

Understanding ZIP code 45121

ZIP code 45121 is assigned to Georgetown, OH, and falls within Brown 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 8,931 people live inside it.

At 84 residents per square mile spread over 106.824 square miles, 45121 reads as a rural 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 run below the national median. At $57,274, 45121 sits in the lower half, ahead of 27% 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 Georgetown looks like

Housing in 45121 costs below the national median. A typical home is valued at $150,800 against a US median of $207,500, and median gross rent runs $680 a month. Ownership dominates: 73.7% of occupied homes are owner-occupied, which usually signals an established residential area with relatively low turnover.

The building stock is dominated by detached single-family houses, which account for 71.5% of housing units here. The median construction year is 1976, making the housing here from the later twentieth century.

The population skews older than the national median, with a median age of 45.1 against 42 nationally. The average household holds 2.34 people, and 59.5% are family households.

Getting to work takes 32.7 minutes on average one way. The dominant mode is drove alone at 82.5% of workers.

Where to stay

Where to stay in Georgetown, OH

45121 covers a rural area, and accommodation within the postal code itself is likely to be sparse — perhaps a country inn, a lodge or a vacation rental rather than a conventional hotel. Widening the search radius is usually the practical approach, and it also opens up more availability at short notice.

Local costs are modest — median rent here is $680 a month — and accommodation prices in the area tend to be correspondingly reasonable. For reference, Chicago, IL is about 285.7 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 45121 is used for

Beyond addressing mail, 45121 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, 45121 offers a compact profile of Georgetown: 8,931 residents, a median household income of $57,274, 19.1% of adults holding a bachelor's degree or higher, and an unemployment rate of 4.3%. 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. 45121 may cover parts of several distinct areas, and a single neighbourhood in Georgetown 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.

Accommodation in and around Georgetown, OH ranges with the character of the area. See the 'Where to stay' section on this page for local context, and use the live search there for current availability and pricing.
Does 45121 cover more than one city or county?
This page lists Georgetown as the primary place and Brown County as the county. ZIP codes follow mail delivery routes rather than municipal or county lines, so a single code can straddle boundaries, and USPS also recognises alternate acceptable city names for many codes. If you need the definitive answer for a specific street address, the USPS ZIP Code Lookup is the authority.
Can ZIP code 45121 change?
Yes. USPS adjusts ZIP codes as delivery volumes shift — codes are occasionally split, merged, retired or newly created, and boundaries move more often than most people assume. The Census Bureau's ZCTA definitions, which underpin the demographic figures on this page, are redrawn only once a decade, so the two can drift apart between censuses.

On accuracy. ACS figures are survey estimates, not counts. The margin of error shown alongside the population figure means the true value has a 90% chance of falling in that range. For small ZIP codes the error can be large relative to the estimate — treat the direction as more reliable than the exact number.
