ZIP 04021 in context
How this area compares with national benchmarks.
ZIP 04021 is a mid-size town in Cumberland County, Maine, with 6,629 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #52 of 427 ranked by population — larger than 88% of them. The median age here is 38.9 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.
Households in ZIP 04021 earn a median of $145,833 a year, 85.7% 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 4.8% of residents here, less than half the 12.4% national rate.
The typical owner-occupied home in ZIP 04021 is valued at $506,800, 67% above the national figure, while median gross rent runs not published a month. The home-price-to-income ratio works out to 3.5×, against roughly 3.9× nationally, so buying is easier here than in the average US market. 93.4% 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.
The Census withheld gross rent for ZIP 04021 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.
Reading ZIP 04021 in context
How 04021 sits inside Cumberland County and Maine.
ZIP 04021 is tabulated inside Cumberland County, Maine, one of 38 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 04021 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.
Against its own county, 04021 reports a median household income of $145,833, 67% above the $87,399 county median, and 122% above the $65,739 typical ME ZIP. Owner-occupied homes are valued at a median of $506,800, 19% above the county figure and 120% 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 04021.
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 04021 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.

Affordability in this ZIP
Derived from the Census medians above — indicative, not an offer.
A rent burden above 30% is the federal threshold for cost-burdened households, and a price-to-income multiple above 4× is generally considered a stretched housing market. The mortgage figure is principal and interest only — taxes, insurance and HOA dues are extra.
