ZIP code 04489

ZIP 04489 is a very small community in Penobscot County, Maine, with 366 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #358 of 427 ranked by population — larger than 16% of them. The median age here is 24.9 years against 39.1 nationally, a distinctly younger profile, typical of places with students, military posts or a fast-growing family population. 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 04489 earn a median of not published a year. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 26.2% 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 ZIP 04489 is valued at $229,200, 24.5% below the national figure, while median gross rent runs $1,403 a month, essentially level with the national figure, or roughly $16,836 across a full year. 66.5% of occupied homes are owner-occupied versus 65% nationally, so the market leans toward owners. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

A median age of 24.9 means a large student or early-career population; income medians in places like this understate household resources, since many residents are supported from outside the address. With 366 residents, a handful of survey responses moves every median on this page. Compare ZIP 04489 against its county rather than against national figures.

The Census withheld household income for ZIP 04489 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

ZIP 04489 is tabulated inside Penobscot County, Maine, one of 41 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 04489 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 04489 reports a median household income of not published. Owner-occupied homes are valued at a median of $229,200, 43% above the county figure and close to the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,403 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 04489.

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 04489 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.
