ZIP 04231 in context

How this area compares with national benchmarks.

ZIP 04231 is a very small community in Oxford County, Maine, with 297 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #369 of 427 ranked by population — larger than 13% of them. The median age here is 60.2 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Households in ZIP 04231 earn a median of $50,893 a year, 35.2% below the national figure of $78,538. Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area. Poverty reaches 10.8% of residents here, below the 12.4% national rate.

The typical owner-occupied home in ZIP 04231 is valued at $221,400, 27% below the national figure, while median gross rent runs $1,156 a month, 17.8% below the national figure, or roughly $13,872 across a full year. A household on the local median income would put about 27.3% 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 4.4×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 87.8% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 60.2 puts ZIP 04231 well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages. With 297 residents, a handful of survey responses moves every median on this page. Compare ZIP 04231 against its county rather than against national figures.

All values below were released by the Census for this exact geography, with no gap-filling on our side. 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.

Reading ZIP 04231 in context

How 04231 sits inside Oxford County and Maine.

ZIP 04231 is tabulated inside Oxford County, Maine, one of 34 ZIP areas the Census publishes for that county and 427 across Maine. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 04231 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 04231 reports a median household income of $50,893, 17% below the $61,429 county median, and 23% below the $65,739 typical ME ZIP. Owner-occupied homes are valued at a median of $221,400, 13% above the county figure and 4% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,156 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

Maine charges 5.5% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 04231.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 04231 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
