ZIP code 04579

ZIP 04579 is a small town in Sagadahoc County, Maine, with 3,135 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #118 of 427 ranked by population — larger than 72% of them. The median age here is 53 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 04579 earn a median of $103,482 a year, 31.8% above the national figure of $78,538. The median is the midpoint household, not an average, so a handful of very high earners cannot drag it upward the way they distort a mean. Poverty reaches 14.1% of residents here, above the 12.4% national rate.

The typical owner-occupied home in ZIP 04579 is valued at $249,500, 17.8% below the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 2.4×, against roughly 3.9× nationally, so purchase prices are unusually low against local pay, the pattern in places where supply is plentiful and wage growth has been flat. 94.6% 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. 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 53 puts ZIP 04579 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. Median income runs above the national figure while poverty also runs above it — a split distribution, not a uniformly comfortable place. Averages hide that; the two numbers together do not.

The Census withheld gross rent for ZIP 04579 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 04579 is tabulated inside Sagadahoc County, Maine, one of 8 ZIP areas the Census publishes for that county and 427 across Maine. Population sits in the small-town band, typically one main street plus the addresses that feed into it. 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 04579 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 04579 reports a median household income of $103,482, 25% above the $82,671 county median, and 57% above the $65,739 typical ME ZIP. Owner-occupied homes are valued at a median of $249,500, 21% below the county figure and 8% above the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at not published 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 04579.

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 04579 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.
